The following story was posted in a Northern Wisconsin newspaper. Although not all situations allow trees to be used, pay special attention to the need for shallow water cover to hold fry. Fishiding products are just the answer to this dilema. Take a look and see why the only American made artificial fish habitat, made from reclaimed PVC is the answer to a green approach to fish habitat management. http:// www.fishiding.com

Vilas County may include structures in cost share program

By Ratchel White Of the Lakeland Times

Fish sticks aren’t just frozen food anymore. In areas where the technique is implemented, “Fish Sticks” refers to fallen trees arranged and utilized for fish habitat. The idea has gained local attention, especially because the structures are suspected to also reduce shoreline erosion.

Researchers studying shoreline restoration in Oneida and Vilas Counties are interested in possibly integrating the technique in their efforts. Vilas County Department of Land and Water Conservation has also eyeballed the technique as a potential candidate to include in their cost share program for landowners combating erosion.

Vilas County land conservation specialist Marquita Sheehan said that with so many lakes, people in this part of the state are likely to pick up on the technique.

Michael Meyer, lead research scientist on the above mentioned efforts, agrees. “Anything that increases people’s likelihood to catch fish is popular,” Meyer said.

And it does seem to be the case that the structures increase the amount of fish in lakes where they have been built. Thats according to Department of Natural Resources fisheries biologist Scott Toshner.

“People who fish in lakes and people who scuba dive or snorkel really like these things because they attract fish. That’s just the bottom line,” Toshner said.

Toshner has been involved with more than 20 “Fish Sticks” projects over the past four years. He has watched the interest in this method of improving lake health and habitat spread to other counties and even out of state. The idea for fish sticks was resurrected from a DNR study in the 1950’s.

The technique arranges entire trees, with their branches, in a criss-cross shape that resembles the letter A.  Typical structures use five tress and take up 25-50 feet of shoreline.

Fish Sticks are assembled on the ice so they will fall into place once the lake surface thaws. The structures are anchored to trees on the shoreline. They require a DNR permit and specialized equipment to build. Toshner estimated the cost of a project as roughly $25.00 per tree.

One project near Bayfield was scaled back because the structures were too near a beach at a public campground. However, Toshner said it was the only instance of controversy surrounding the structures.

Projects to put in structures have mainly been on private property and with landowner’s cooperation.

In all cases except for the above, Toshner said that response to the structures on lakes where they are put in is overwhelmingly positive. They have gained a reputation as improving fish habitat, though he said that the structures also improve turtle and other wildlife habitat.

In comparing the structures to fish cribs, Toshner indicated that they may provide a missing link in terms of fish habitat. “With the fish cribs, the one thing you kind of miss with them is the link between the near shore area where a lot of theses fish spawn and spend their lives as juveniles…[with fish sticks] the wood in this near shore area may be a missing link in terms of habitat in some of these lakes,” Toshner said.

In addition to improving habitat for lake critters, there is furthewr evidence that these structures may reduce soil erosion. However, the evidence remains annecdotal.

A UW-Steven’s Point study is attempting to confirm observations that the structures help prevent wave action and can build up eroded shoreline. Right now, it’s the growing interest in these structures that is is the most encouraging side effect, according to Toshner.

Lakes in Eau Claire, Douglas and Bayfield Counties currently have fish sticks structures, and Toshner said the forest service in the Michigan  Upper Penninsula and groups out of Minnesota have also expressed interest.

More interest leads to more awareness of the benefits of fish sticks projects, according to Toshner. The educational component of current projects cannot be overlooked, he said, especially for people who live out on the lakes.

“If they see this and they see that it’s a good thing, which is what we’re seeing, then they’re more apt to leave that tree in that fell along the shoreline instead of removing it,” Toshner said. “If people can see that trees in the water are a valuable resource, they’re less likely to remove a tree that might fall inj along their own shoreline.”

Action Plan News Status of Fish Habitats Report Gives “Fish Eye View” of National Waters
Status of Fish Habitats Report Gives “Fish Eye View” of National Waters
THURSDAY, 14 APRIL 2011 15:13
The National Fish Habitat Board (www.fishhabitat.org) today released a first-of-its-kind status of fish habitats in the United States report as envisioned in the National Fish Habitat Action Plan, an effort to protect, restore and enhance our nation’s aquatic habitats. The report titled THROUGH A FISH’S EYE: The Status of Fish Habitats In The United States 2010 summarizes the results of an unprecedented, nationwide assessment of the human effects on fish habitat in the rivers and estuaries of the United States.

Through a Fish’s Eye, provides an important picture of the challenges and opportunities facing fish and those engaged in fish habitat conservation efforts. Urbanization, agriculture, dams, culverts, pollution and other human impacts have resulted in specific areas of degraded habitat where restoration is most likely needed to bring back the healthy habitats and fishing opportunities that once existed. Addressing degraded habitat also requires reducing or eliminating the sources of degradation mentioned in this report, through best management practices, land use planning, and engaging landowners, businesses, and local communities in the effort.

The assessment detailed in the report assigns watersheds and estuaries a risk of current habitat degradation ranging from very low to very high. These results allow comparisons of aquatic habitats across the nation and within 14 sub-regions. The results also identify some of the major sources of habitat degradation that plague waterways across the nation.

Overall, 27 percent of the miles of stream in the lower 48 states are at high or very high risk of current habitat degradation and 44 percent are at low or very low risk. Twenty-nine percent of stream miles in the lower 48 states are at moderate risk of current habitat degradation.

Fifty-three percent of estuaries (by area) are at high or very high risk of current habitat degradation, while 23 percent of estuaries are at low or very low risk of current habitat degradation. Marine habitats of the United States tend to be most degraded near the coast, where they are most affected by human activity.

The goal of the national assessment was to estimate disturbance levels to fish habitats in rivers and estuaries from information about human activities occurring in the watersheds and the local areas affecting each aquatic habitat. This approach is supported by a large body of scientific research showing that human disturbances to the land transfer to receiving waters and contribute to disturbance in downstream fish habitats in rivers, estuaries, and the ocean.

While the specific analytical approaches used to assess habitats in the lower-48 states, Alaska, Hawaii and U.S. estuaries differed slightly, the end product of each analysis was similar—an estimate of the risk that discrete habitat units will be degraded due to current human activities on the landscape.

“This report identifies areas where those efforts are most needed and points to areas where fish habitat is most likely still intact and should be protected to maintain its value for fish and other aquatic organisms. Resources for fish habitat conservation are limited, especially for the next few years,” said Kelly Hepler, Chairman of the National Fish Habitat Board.

“Fish Habitat partnerships ensure coordinated work around specific habitat challenges,” said Eric Schwaab, Assistant Administrator for NOAA Fisheries. ”This information will help bring strategic focus to conservation efforts and allow rigorous measurement of results.”

“This report clearly illustrates the need for strategic use of existing resources through partnerships that can identify the most effective use of funds and help the nation as a whole make progress in fish habitat conservation,” said U.S. Fish and Wildlife Service Acting Director Rowan Gould. “There are many major threats to the health of fish habitat and the National Fish Habitat Action plan helps to focus and leverage available funds, pool technical expertise, and enlist new partners to address the challenges to fish habitat.”

Key findings from the “Through a Fish’s Eye: Status of Fish Habitats” report include:

Habitats with a very high risk of current habitat degradation include those in or near urban development, livestock grazing, agriculture, point source pollution or areas with high numbers of active mines and dams. Specific locations that stand out as regions at high risk of current habitat degradation include: the urban corridor between Boston and Atlanta; the Central Midwestern states of Iowa, Illinois, Indiana and Ohio; the Mississippi River Basin, including habitats adjacent to the lower Mississippi River in Arkansas, Mississippi and Louisiana; habitats in eastern Texas; and habitats in Central California and along the Columbia River in Oregon and Washington.

Areas that stand out as being at very low risk of current habitat degradation include rural areas in New England and the Great Lakes states; many habitats throughout the Mountain, Southwest and Pacific Coast states; and most of Alaska. It should be noted that not all water and land management issues could be addressed in the assessment, so some of the areas mapped as at low risk of current habitat degradation actually may be at higher risk due to disturbance factors not assessed. For example, most arid regions of the western United States were found to be at low risk of current habitat degradation.

Estuaries in the mid-Atlantic have a very high risk of habitat degradation related to polluted run-off and other effects of the intense urbanization and agriculture in this area. The estuaries of southern California also have a high risk of current habitat degradation for similar reasons. Estuaries in the north Pacific and downeast Maine have a low risk of current habitat degradation.

The release of this report is also accompanied with the release of a map viewer, which offers the maps that are in the report in greater detail. The National Fish Habitat Action Plan map and data web tool (www.nbii.gov/far/nfhap) was developed by the U.S. Geological Survey’s Biological Informatics Program under guidance of the National Fish Habitat Action Plan Science and Data Committee. This tool not only enables users to see multiple views depicting the condition of stream and coastal habitats across the country, but also means that users can access more detailed information at finer scales, as well as the option to download data files and map services.

Well folks now that the winter is near over and the ice is off most of the lakes, ponds, rivers and streams all we need to do know is wait for the crappie spawn to catch some big slab spring crappie Wrong! Spring crappie fishing right after ice out is the most amazing time of year to catch trophy slabs. The fishing pressure will be light because of the still very cold weather. If you can tolerate some very inclement weather you will experience some of the most amazing spring crappie fishing.  

After ice out it is time to go out and start your spring crappie fishing. The crappie are still in deep water but will start their move into holding areas close to their spawning beds. They will be hungry and will their feeding in earnest The water is extremely cold, so you will have to use a very slow bait presentation. The trick is being able to locate the fish, there are some fundamentals you need to be aware of to find the big slab pre-spawn spring crappie. Oh you won?t have to be out on the lake at first light either. It has been my experience , afternoon is better this time of year because there is some sun warming and the crappie feed on the moving bait fish more in the afternoon.

Start your fishing at the last ice fishing location. If you don?t ice fish contact some ice fisherman and find out their last fishing locations. The fish will be holding at these locations right after ice out. If your lake is shallow, head to the deeper boat channels around your lake, the fish will be locate here. In deeper lakes head to narrowing creaks and channels feeding off the lake the spring crappie will be located there. I rivers head for channels that feed off the main river.  

When fishing In cold water I prefer ultra light equipment. When your fishing for spring crappie the bite will most likely be very light. You need to be able to feel the bite to catch fish Use 2lb test and an open face reel and a graphite rod, with a good tip. If you are breaking line and snagging a lot move to 4lb fluorocarbon.. I recommend you use 1/32oz or 1/16oz jig heads that have eyes painted on them. The color of the jig head can very, but my preference is chartreuse or pink. with split tail plastic tubes. with some glitter color. My preference is to use clear color tubes with some glitter color in them for clear water. In murky water use white or yellow. If the water is real muddy use chartreuse.

If you use these tips you will be successful. When you catch a giant slab crappie in early spring there is no better feeling. Well good luck with your spring crappie fishing.

Don’t for get to build up the fish habitat for your crappie to enjoy. Shallow habitat for fry is the first step in growing big slab crappie. Artificial fish attractors and fish habitat grow algae fast and protect young fry for larger predators.   Fishiding.com

Structure Fishing 101
By Paul Crawford
If there has been any real revolution in fishing over the last 20 years, it’s been “structure fishing”. Bass fishing as a sport, depended on shallow water “bank beating” since it’s inception. Over the last 20 years, it has become fashionable to wander off shore in search of more and bigger fish. Much has been written and discussed, but there still seems to be some confusion over structure fishing, even among the pros, and the majority of the fishermen have just become off shore fishermen, not structure fishermen. Let’s look at what we mean by structure fishing, and some of the tricks of the trade.
The definition of structure is a change in bottom contour, (I.e. depth), which results in an irregular feature on the bottom of the lake. Now just about any quick change in depth results in some type of structure, a hump, point, ledge, or something. The biggest misunderstanding seems to be the definition of “quick”. Quick is a relative term. In a traditional reservoir, this could be anything from a vertical drop to a gentle slope dropping 5 feet over a 30 yard distance. In a natural Florida lake, where it may normally take 1/4 mile to change depth by 1 foot, it may be a 6″ deep channel running through a 5 foot deep flat, or a two foot drop over 30 yards. Where ever you find it, structure is another edge in the underwater world, and we all agree that fish just love edges.

Let’s spend just a minute talking about what structure isn’t. Structure isn’t a weed bed on a flat, or an isolated stump, or a brush pile. All of these things are “cover”. A weed bed may constitute a different type of edge, both of the weeds and of the bottom composition, but not structure. Wood, whether natural or man made, is just some place to hide. Likewise, a feeding flat is a place, not a structure. We all have seen times when fish are on the flats and relating to cover. Even during those times, there will still be some fish around the surrounding structure. Even on days when the fish are straying away from structure, they generally won’t go that far if they don’t have to. Learn to recognize structure and it can narrow your search for fish dramatically.

Now that we can agree on what is structure and what is cover, we can also agree there are times when one or the other seems most important. Deep structure without cover can and does normally hold a few fish, but generally not a great concentration, at least of bass, (catfish and crappie are another story). And we blow by miles of shoreline or shallow water cover every trip that doesn’t have a concentration of bass. But put the two together, and you generally will find the fish stacked at least some of the time. The trick then is to know the other variables and be there at the right time. And every once in a great while we can find that honey hole with both structure and cover that have fish all the time, at least until we fish it out and have to find another one.

Types of Structure

We can define structure types by the relationship to the surrounding depths. The basic component of structure is the ledge. A ledge is simply a distinct change in depth. In a southern reservoir, this might be a drop of 5 feet over a twenty foot slope. In Florida, it is most times a drop of 6 inches to 1 foot over the same twenty foot slope. A ledge, by our definition, is a fairly straight line of depth change. Start putting some noticeable curves along the lip of a ledge, and you get other structure. A point is a protrusion of shallower water along a ledge. Surrounded by deeper water on three sides, it is the most recognizable and often the most productive type of structure. The opposite of a ledge is a cut. A cut is an indention in the line of a ledge with deeper water surrounded by shallow water on 3 sides. A hump is nothing more than a ledge that wraps around on itself, or an underwater island of sorts. A hump has deeper water on all sides. The opposite of a hump is simply a hole, literally deep water with shallow water on all sides. There are several other types we can talk about, but these are the basic types.

We now have our basic definitions, but we need to put some size restrictions on them, else everything is some type of structure. For instance, the main lake body could be seen as a hole, or simply a round set of ledges. We need to decide which one because we’d like to fish the structure differently depending on which type of structure we call it. As a reasonable guide, let’s look for just a second on how fish use structure. Structure, what ever it’s form, is a type of underwater transportation system. Fish generally follow a narrow depth getting from one place to another. The advantage of using structure edges is the deeper water provides an immediate escape route if you happen onto something much bigger than you. Now just like any road, fish rarely live right in the center lane. More likely, they will be just off one side or the other, which is were the cover part comes in. In any event, for our purposes, the extent or limit of a useful definition for a structure is the depth change itself and the reasonable area adjacent to the drop where fish will wander off to feed. In the case of our hole, a fish might reasonably wander out, say 100 feet into the hole without loosing the advantage of the edge for chasing shad. So, if we assume both sides of hole are good for 100 feet, then anything that is over 200 feet wide, at it’s narrowest part, isn’t a hole, just two separate ledges. Similarly, if a hole is too small to make use of each side, you have a ditch or a depression, not a hole. Each of these other cases may be useful, but for our discussion, they aren’t holes. Apply all of the same comments to the other structures: points, humps, cuts, etc.

Cover and Structures

Even with our size restrictions, we still have a tremendous area to work. But we can narrow the odds by putting one additional restriction on our prime structure. We already said we’d like structure with cover, but let’s now say we want the cover to end along the edge of our structure. A point with a grass bed is good. But if the grass bed happens to end right at the edge of the point, then the point is great!

Weed beds in particular are excellent types of cover to either change types, or stop all together right at the lip of the structure. A ledge may have heavy grass in say 10 feet on the top edge, while have either a different type of grass or, even better, no grass at all at the bottom edge. If you work the outside of the weed bed, you actually are working three edges at the same time, the vertical edge of the grass, the edge of the weed bed, and the depth change of the structure. Add a small point or cut in the straight ledge, and you have 4 or 5 edges. This is the kind of high percentage spot worth spending hours to find.

Standing wood is another case of cover at a structure. When you are fishing an old road bed or creek channel and the wood suddenly stops at a particular depth, you get all the advantages of the structure and the cover. I have found it necessary to be careful with defining wood on a ledge. Where you have creeks or roads, you a likely to also have hills or mounds. In this case you need to find a structure on a structure. Just because to the bed runs at a consistent depth, the top edge will, more often than not, rise and fall over mounds or small hills. A gentle slope up an underwater hill may concentrate the fish at a single tree because the depth is 6 inches different than the surrounding trees. If you don’t know what depth, it can be frustrating. On the other hand, a slight mount in on one side of a bed can act as a magnet for every fish in the area not actively hunting. Find an area with several of these mounds and you’ve got your honey hole. Depending on the local botany before it was flooded, you may be able to spot these mounds by looking for a specific type of tree which grew only on a mound or down in a cut. A perfect example is willow trees that would tend to have grown lower and closer to the water level of an old creek than say the surrounding oak trees. Cypress trees are another sure tip off of a change in structure level. You’ll read many times about a tournament won fishing a specific type of tree. More than likely, it wasn’t the wood type that made the difference, it was depth that type of tree was growing in before the lake was built.

Water Temperature and Structure

We’ve now established looking for a structure with cover, it’s time to chose among all structures with cover that ends at the structure edge. This will depend on several variables, water clarity, weather, season, stratification, temperature, etc. We could try to consider everything, but for starters, there is an easier way. Most of the changes can be interpreted as water temperature. Like any other generalization, it doesn’t work all of the time, but for 80 – 90% of the cases, it works just fine.

The general rule of thumb: “The Colder the Water, The Steeper the Drop.” Pretty simple, and it works. During winter and early spring, look for the fish to relate to a steep drop into deep water. This might be from 5′ or from 20′ into a deep hole, but the fast drop is the key. The fish will move during warmer periods to the upper shelf to feed and may suspend over the hole during those blue bird cold fronts. During summer and well into fall, look for a gentle slope into deeper water. The fish may range a couple of hundred yards from the structure but at least some will be on slope for most of the year. The only tough part about this is they may actually move deeper to feed and return to the slope to rest. But again, for the most part they will move into the cover for feeding while the bait is on the bottom.

Everything else being equal, we still don’t know at what depth we should look for our structure. In the Florida Chain Lakes, with different water clarity in different lakes, you can still find structure, with cover, the correct type of slope, and the correct contour in just about any depth. The tie breaker is again water temperature, just not surface temperature anymore. The most productive structure, all things being equal, will be where the structure tops out at the same depth as the thermocline. A thermocline, for those not normally worrying about those things, is a physical layer between two different temperatures of water. This normally exists when the lake is “stratified”, or during the summer when there is little movement between the upper and lower water layers. In this case, the cooler water will remain below the warmer upper layers. In the fall, as the upper water cools, it will normally fall within the water column, causing a lake to “turn over”, normally tough days to be fishing. Anyway, a structure near the thermocline with appropriate cover, can be a gold mine for fishing.

There are several ways to find a thermocline if one exists. The most obvious, and the most trouble, is to lower a temperature probe and look for a dramatic, (3 – 6 degrees), change in temperature. An easier way is to use your depth finder. A thermocline will reflect sound waves if the temperature change is great enough. Move to deep water and place your unit in manual mode. Increase the gain, (sensitivity), until you see a solid or broken line in the middle of the water column. If your depth finder has the little fish symbols on it, this may take the form of a line of fish around a particular depth. As you move the boat, this line may move slightly up or down, (a foot or so), but should remain pretty close for a given area. Find structure at that depth, and you should find fish. By the way, during the dog days of summer, you may find 2 or 3 thermoclines at the same time. Generally, the fish won’t be below the lower one, (commonly about 25′ in Florida). If you have 3 or more thermoclines, (more common on reservoirs where water 50′ plus is the rule), fish the middle one.

Fishing Structure

The absolute most important thing for fishing structure is your depth finder. A depth finder which can mark in 1/10′ or in inches is ideal for this application. Also, you’ll find it more comfortable if your depth finder is mounted on the bow with the transducer attached to the foot of the trolling motor. If you have only one depth finder, mounted on your console, then keep in mind the depth being shown is for the stern of the boat, not directly under you and your trolling motor. Get to be best friends with your depth finder, for structure fishing, it’s the most important piece of gear you’ve got.

Most of the time, you’ll find the majority of the fish on the top lip of the structure. The rest of the time, you’ll find the fish suspended just past the lower edge at approximately the same depth as the upper edge. Boat position is the key to effectively fishing the structure. Run up and down your structure a time or two and get to know the rate of the slope and where it bottoms out at. Position the boat so at a full cast length, your lure is about 10 over the top edge while holding the boat in deeper water. Keep the boat at the same depth as you follow the contours of the structure. If you find a narrow cut, back off and fish the bottom of the cut as well as moving in and fishing the surrounding lip. If you move over a point, make sure to go back and fish the normal edge line across the top of the point as well as following the point out into deeper water.

While you’re fishing the top of the ledge, don’t forget the deeper side of the boat. Every 6 or 8 casts, turn around and heave one out into open water. Make sure you monitor your bait on the drop, that’s were the bite will be for suspended fish. Pay particular attention to suspended fish around the ends of points and at the corner of flats. More to see in the fishiding news page

After you’ve finished a run on a structure’s top edge, if it still looks promising, make another pass fishing the bottom edge. Position the boat as close as you can to the top edge, (where you’ve just fished), and use your bait to “feel” you way along the bottom edge. If the cover stops on the top edge, many times a different scattered grass, limbs, or simply trash will pile up on the bottom edge. If you can’t feel anything, and when all else fails, you can count down your lure and get a pretty consistent feel for the depth you’re fishing. This is also the pass you’d like to fish straight across points and cuts looking for fish suspended in the middle. In general, this deep water pass will also be your best bet of sticking that kicker you’re looking for.

If you think there are some suspended fish in the area, try a long Carolina rig. Instead of simply pulling the bait along the bottom, pop the bait up in the water. As the sinker drops, the bait will actually whip upwards and you can effectively cover 6 or 8 feet off the bottom. In these situations, expect a very light bite and give the bait plenty of time to float back to the bottom before the next jerk. It won’t be unusual to not feel anything and simply have a fish on when you raise your rod. You can increase your hook up ratio by gently raising the rod tip and feeling for pressure before jerking the bait off the bottom. This is a prime example of the wisdom of the adage, ” The Jerk’s Free”.

There are a hundred other ways to fish various structures, and there are many more variations of the structures themselves. We’ll look in future articles at the more specific structures and techniques, but this pretty much covers the basics. Give structure fishing a try and I think you’ll like the results. Like most other techniques, it more a matter of confidence than anything. Given the right situation, structure fishing can open up a whole new world of schools of fish and big bites!

CATCH AND RELEASE OR SELECTIVE HARVEST? – BY DR. RICHARD O ANDERSON
Thursday, January 27, 2011 at 5:33pm
Dr. Richard Anderson is a legendary fisheries biologist who helped develop relative weight tables of fish that today’s biologist use religiously. He resides near Houston, Texas.

Grandpa told me a long time ago. “If they’re big enough to bite, they’re big enough to keep.” I’ll always remember his philosophies. He grew up in an era where fish were for food more than fun.

I’ll also never forget the time my wife caught two bass on the same plug, undernourished fish chasing anything that hit the surface of the pond. Such fishing memories are priceless.

The philosophy and approaches to management of fish populations in ponds have changed a great deal since the good ole days. We have a much better understanding of fish population structure and dynamics because of research on fishing ponds in the Midwest.

Should I keep this fish or put it back? For some people, largemouth bass have become a sacred cow and the answer is obvious. Catch and release has been a benefit to the quality of fish and fishing in many larger and public lakes.

But, this is not so in most private lakes and ponds. In lightly fished lakes and fishing ponds there is often a surplus of eight to twelve inch bass.

It helps to make an educated decision about which fish to keep or release if you know the fish population structure: e.g. length-frequency distribution of bass and panfish. The index of size distribution is called “proportional size distribution” or simply “PSD.”

Specific lengths of fish define “stock,” “quality” and “preferred” sizes. For largemouth bass these total lengths are eight, twelve and fifteen inches: for bluegill these lengths are three, six and eight inches. The index is determined as a whole number as the proportion of fish longer than quality size in stock. If ten largemouth bass longer than eight inches are caught and two of those are longer than twelve inches the PSD is 20: if no fish are caught longer than 15.0 inches the PSD-P is 0. Angling is an excellent way to estimate population PSD of bass.

Tracking PSD is an excellent way to keep a running tabulation on the progress (or lack of) of your fish populations. PSD is a useful tool for a lake or pond manager to make decisions when (and which) fish to harvest.

However, size of bluegill caught by angling does not reflect fish population PSD because few or no fish as small as three inches are caught. People just don’t fish for tiny bluegill. When six to eight out of ten bluegill caught are quality sizes the population PSD is probably between 20 and 60. Consider this a well-balanced population of those key panfish. When few or no bluegill longer than six inches are caught, the PSD is likely less than ten; fish are probably stunted with slow growth and high natural mortality. Only the smallest of age-4 survive to age-5.

The number 3.0 to 5.9 inches long can be in the thousands per acre. In several Midwest fishing ponds with a bluegill PSD less than 10, total weight of bluegill was three hundred or more pounds per acre i.e. carrying capacity for bluegill. With an increasing PSD there was a decline in bluegill standing crop such that when PSD was about 60 bluegill biomass was about 150 pounds per acre or 50% of carrying capacity.

With lower standing crop there is little competition for food in the fishing pond and individuals grow faster, live longer and some reach preferred size. Adequate predation by bass of quality size can reduce numbers of stock and quality size of the fishery down to hundreds per acre and a PSD of 60.

When the PSD of largemouth bass is less than 10 they may also be stunted and few survive to age 5. Their condition or index of well being called “relative weight” (Wr) is probably less than 90. This common fish population structure can result from a twelve-inch minimum size limit or a preference to keep bass of quality size. The PSD of such fish populations can be increased with selective harvest of bass less than twelve inches while releasing all bass of quality size. This process is called, “selective harvest.” Maintain that selective harvest until the proportion of fish eight to twelve inches long is equal to those twelve to fifteen inches long. With these proportions the Wr of both fish size groups should be about 100, or the optimum value for growth efficiency: i.e. about three pounds of gain for each pound of fish consumed. When competition for food is keen and Wr is low, fish may lose weight or it may take five to ten pounds of prey for a bass to gain one pound. When there is a surplus of prey and Wr is well over I(X), growth efficiency is lower because excess protein is converted to fat.

All pond owners should spend some time keeping track of numbers and sizes caught by angling in their fishing ponds. Set up a spreadsheet in your computer and track each year’s catch records by plotting bluegill PSD on the vertical axis and bass PSD on the horizontal axis. Both scales should be 0 to 100. Estimate bluegill PSD by subtracting 20 from angling PSD unless numbers are near O or 100. For the records just keep track of the numbers of bluegill shorter and longer than six inches total length. For example-if three bluegill less than six inches are caught from your fishing pond and seven longer than six are landed the angling PSD is 70 (7 divided by 10 x 100) and the estimated population PSD is 50. All fishing ponds with bluegill and largemouth bass will be plotted somewhere on this graph.

Decide your pond management objectives. If you prefer larger bluegill, protect more bass and be satisfied with a PSD less than 30. If you prefer to catch larger bass harvest those less than 15 inches long and catch and release those of preferred size.

When the PSD’s of bluegill and bass in your pond is around 60, you have reached the balance of nature, the way these fish populations have evolved. About 40% of bass will be 8.0 to 11.9 inches long, 40% 12.0 to 14.9 inches long and 20% longer than 15 inches. Your fish population will be near carrying capacity for bass and panfish populations will be near 50% of their carrying capacity. In a typical Midwest fishing pond this could be 150 pounds of bluegill and 40 to 50 pounds of bass. This structure can be sustained by catch and release of all bass and bluegill.

You are likely to be dissatisfied with low ecological efficiency of mediocre fish populations of PSD less than 10 of both bass and bluegill. But, such fishing ponds are ideal to introduce your children or grandchildren to fishing. These hungry fish are much easier to catch than fish in well balanced populations.

Some of my favorite fishing memories are from a 35 acre private fishing lake in Boone County. Missouri. It was opened to fishing with a twelve-inch minimum length limit to prevent initial overharvest of bass. After two seasons, it was obvious there was a surplus of eight to twelve inch bass in the fishing lake. The regulation was changed to protect bass twelve to fifteen inches long, the first ever application of a “slot limit” on bass. Gizzard shad were also stocked, to help forage fish production. After two years, the Wr of bass of all sizes was over l00. Over the next five years the angling PSD of bluegill ranges from 50-90 and bass PSD ranged from 20 to 60. The regulation was considered a success for the fishery.

But, for those few years with bass PSD of 10 and Wr near 90, this lake was unforgettable for my family. My daughters were about eight and ten years old at the time. They were more into “catching” than “fishing.” There was a hatch of black caddis flies (Trichoptera) and bass were behaving like trout. Any cast near a rise produced a strike. I didn’t catch any fish that day. Didn’t have time. Only had time to unhook and release what they caught. Those memories, too, are priceless.

Maybe we should have kept those fish?

We made it home safe from the 600 mile drive to Big Cedar Lodge for the Pond Boss convention this past week. Many new friends were made as well as building and improving business relationships. These folks are all about enjoying all aspects of the great outdoors.

Allen warren was on hand to talk about the growing concern for our kids, missing out on all that the outdoors have to offer. He is spearheading a national movement to get outdoor education to be offered to our kids at school. The important traditions of spending time outdoors, learning and applying the skills of woodsmanship,hunting,climbing,mountaineering,fishing and camping, are just some of the skills that are not getting passed down to the kids.

All the information is available at www.isupportoutdoored.com for everyone to get involved. Celebrities and folks from all over the nation are getting involved to help. Please look into this first of it’s kind movement to ensure our future generstions have the oppourtunity to enjoy all nature has to offer.

Brad Wiegmann was also on hand to cover the event. His unique style of writing comes from a strong love for all things fishy. Brad is a freelance outdoor writer from Sprindale, Arkansas, who adds his photography skills to his writing abilities. He also has been guiding professionally for years, adding to his experienced eye for a story when water is involved. Here is a link to his site and the story hot off press:

The fishing is great on Tablerock and we were lucky enough to catch a few. The weather was pushing 80 degrees, a far cry from what we came home to. A fellow friend and crappie nut from www.crappie.com gave us some spots to fish and they were dead on. What a advantage to have friends with a common bond of the outdoors offering their help to make our trip the most enjoyable possible. 

We caught a number of smaller male bass, staging for the spawn as well as a bunch of crappie to pack on ice to enjoy with friends at home. New places and friends to return to the next time we head south into the great state of Missouri. Thanks to all.

The family at Pond Boss is truly a passionate group of folks who love to be outside, usually around water. Many of the attendees came from the south where heat is a constant issue raising fish and aquatic balance. I can’t imagine dealing with water temps over 90 degrees, when we come home to a 2″ snowfall. Spend some time looking through the pond boss site and you will find topics and answers to all water related things and beyond. Countless folks are always on hand to reply to a question or concern, often with humor but always with a sincere desire to help. www.pondboss.com
