Small Fisheries Revitalization Using Largemouth Bass (Micropterus salmoides) as an Indicator Species

Largemouth bass are a good indicator of pond health and will specify the health of the tested pond after the treatment of any adversary conditions.  The study follows the set guidelines obtained by Brady (1981) to determine the procedure needed to correct any problems concerning the pond.  The study involved treating any flaws related to the pond and monitoring its effect on the bass caught.  The bass were then compared to the pre-treatment bass to determine the effect of the revitalization.

Ponds offer an excellent setting in which to study aquatic ecosystems simply for the reason that you can control many of the variables. Because largemouth bass (Micropterus salmoides) are the top predator in a pond, they are affected by everything that lies beneath them on the food chain. This makes largemouth bass one of the best indicators of problems within a pond.  The data gathered in this experiment will specify the elements that need to be added or changed to create healthy pond, which will be indicated as it becomes a good fishing resource for largemouth bass.

There are many factors that contribute to the health of a pond.  Fish attractors such as brush should be placed at different depths throughout the pond.  These attractors will allow a place of ambush for large fish and a refuge for smaller fish.  The shallowest part of the pond should only be two feet deep; this depth will prevent the growth of foreign aquatic weeds.  The temperature should range between 64 and 90 degrees Fahrenheit in order to promote maximum fish growth.  Fish will tolerate a pH range of 4.6 to 11, but will thrive in water with a pH of 6.5 to 9.0.  One side of the pond should be shaded and the other should be open to the wind to churn the water and produce oxygen.  There should be enough phytoplankton to cloud the water, which will indicate that there is a sufficient amount of oxygen to sustain aquatic life (Oster, 1983).

In order to manage a productive pond one must understand the delicate balance of the ecosystem in the pond.  Located at the bottom of the food chain are plants called phytoplankton which use chlorophyll to produce food.  Zooplankton feed exclusively on phytoplankton.  Smaller baitfish feed on zooplankton.  Bream feed on small baitfish, insects, and worms.  Largemouth bass feed on anything from four-inch bream to large snakes (Oster, 1983).

Once a pond is considered unhealthy, a number of tests are run to determine the procedure needed to revitalize the pond.  The pH of the water must be tested.    If the pH is too low, limestone can be added at a ratio of one ton per acre to raise the pH by one unit.  Unfortunately nothing can be done to remedy a high pH (Brady, 1981).

An additional test is needed to determine the quantity and type of phytoplankton present in the pond.  Phytoplankton play a key role in producing oxygen.  If the population of the phytoplankton is too low, the oxygen level will decrease causing fish kills.  Therefore fertilizer must be periodically added to promote the growth of the phytoplankton, but can only be added when the temperature reaches 65 degrees Fahrenheit.  Pond fertilizer is composed of four parts phosphorus, four parts nitrogen, and two parts potassium.  The fertilizer may be applied anywhere between six and sixteen times a year, depending on the natural fertility of the pond (Brady, 1981).

If there is an overgrowth of phytoplankton, it will block the sunlight that other aquatic plants need for photosynthesis.  When the plants die, bacterial decomposition drains the pond of oxygen.  This oxygen depletion will have a devastating effect on fish.  To counteract the increase of phytoplankton, lime is added to slow the population growth (Pond Management Guidebook, 1989).

Oxygen deficiency is deadly to a pond, but it is easy to fix.  A test kit is used to find the oxygen level of the pond.  If the level is too low, an aerator puts fresh water back into the pond.  The added water should be sprayed through the air so that it causes a splash as it hits the water to intensify the oxygen content.  Another way to increase the oxygen level is to pump water from the bottom of the pond into the aerator.  The oxygenated water, located at the surface, will then shift to the bottom at a faster rate.  The water at the base of the pond will pass through the aerator and back to the surface creating a cycle (Pond Management Guidebook, 1989).

The main food for the largemouth bass in a pond is small bream that spend much of the summer in the vegetation.  If the aquatic plants are too dense, the bream will escape from the bass that are waiting to ambush its prey.  If all the vegetation is removed, the pond becomes oxygen deprived, and the bass lose their places of ambush.  The vegetation must be controlled to provide the optimum conditions for the fish.  Herbicides or aquatic mowers can be used to trim the population, and fertilizer can be used to boost the plant population (Oster, 1981).

In a proper ecosystem, there is a delicate balance between the predator and the prey.  Within the pond, the bass must feed on bream, or the bream will eat the bass eggs and decimate the population.  If the bass population is too large, the bream population will decline and the struggle for food will increase (Fig. 1) (Pond Management Guidebook, 1989).

Study Question

The purpose of this study is to correct the problems within a pond that have contributed to the reduction in fish population over the past three years.  A drop in the number of fish caught indicates a decline in water quality.  Once the problems are fixed, the number of fish will increase along with water quality.

Study Site

This study involves a man-made pond that has a small population of underweight bass.  The pond spans four acres and ranges from 0 to 12 feet deep.  The only wooden structure of the pond is a massive brush pile is at deepest part and lines the entire bank. The edges of the pond present shade on one side and an open bank, where the wind churns the water, on the other.  Water opposite the levy is shallow and offers a place for the fishes to spawn and feed.  The pond is sufficiently fertilized because there is an ample amount of vegetation and phytoplankton growth.

Methods

The methods described in Brady (1981) will be implemented to increase the number of fish caught and ultimately improve the water quality.

Results

The number of largemouth bass caught after pond treatment compared to the number of largemouth bass caught before treatment will indicate the health of the pond.  Lime, aquatic mowers, and  modified topography will be used to correct different problems related to the pond if necessary.

Conclusion

When all of the problems within the pond are corrected, the amount of largemouth bass caught should increase along with a physical growth of all the species.  The number of fish caught will serve as an indicator of pond health, and therefore of water quality, which is a major concern of people today.

Public Works Builds Fish Habitat in Upper St. Clair

The stream in front of the post office will now be better for fish life.

By Becky EmmersEmail the author | May 20, 2011

The Upper St. Clair Public Works department teamed up with the Pennsylvania Fish and Boat Commission during National Public Works Weekto help improve the stream that runs in front of the post office along McLaughlin Run Road.

“We had a need for some bank stabilization,” said Dave Kutschbach, superintendent of projects for the public works department.

The organizations worked together to design a project that stabilizes the bank and creates a fish habitat.

“We created structures that directs the water down the center,” Kutschbach said.

Channelizing the stream will prevent bank erosion along with providing structures for the fish to live under.

“The structures create some overhead cover for the fish to stay away from predators like birds and raccoons,” said Jon Thomas, from the Pennsylvania Fish and Boat Commission.

Thomas said the new structures give the possibility of creating more fish life in the stream.

“There isn’t much here right now, but they’ll start to congregate,” Thomas said.

The fish include basic minnows, daces and carp, he said.

“The structures will stop sediment from going into the streams and make the water better for the organisms,” said Keith Beamer, of the Pennsylvania Fish and Boat Commission.

The Allegheny County Conservation District was also involved with the project.

“It provides dual benefits. Better relationships develop between the township, nonprofits and state organizations,” said Amy Miller, of Allegheny County Conservation. “And it results in a cleaner stream. There’s going to be less sediment so that means less flooding. And it makes it prettier.”

“This project is an example of the township’s commitment to conservation and clean streams,” Kutschbach said.

The public works department also celebrated National Public Works Week with an open house for kids and the community. Click here to read the article.

 

Fishiding helps Premier Outdoor Properties,Inc. improve fish habitat

cribs ready to go
We recently sent a custom artificial fish habitat arrangement to Nebraska to be installed in Aaron Graham’s personal pond at his home.  Aaron and his two boys stayed up late the night they arrived, each of them creating ther own personal fish attractors by bending them into shape.  We put together a plan for him with a lake map he provided showing depth, contour and swimming areas. After the habitat has been installed, the boys will be sure to let us know how they are doing.

This trout may look like a trophy, but it’s likely a rainbow-cutthroat hybrid. An ongoing FWP project is trying to stop hybridization of trout in 21 high mountain lakes along the Hungry Horse Reservoir and in the Bob Marshall Wilderness.

Posted: Tuesday, May 17, 2011 2:11 pm

By CHRIS PETERSON Hungry Horse News | 0 comments

 

On a hot day last summer, biologists from Montana Fish, Wildlife and Parks ventured to Danaher Creek, deep in the Bob Marshall Wilderness, and caught hundreds of young purebred westslope cutthroat trout.

The fish made the 24-mile journey out of the wilderness on the backs of mules, packed in water-filled coolers fed with bottled oxygen. Once out of the wilderness, they were transported to their new home at the Sekokini Springs hatchery in Coram.

“We had 100 percent survival,” FWP biologist Matt Boyer told interested anglers last week.

Many of those fish and their offspring will have a new home in the Necklace Chain of Lakes in 2012 as part of an ongoing effort to preserve westslope cutthroats in the South Fork.

Since 2007, the Westslope Cutthroat Trout Conservation Project has slowly, but surely, been replacing non-native fish and hybrids in lakes in the South Fork drainage in an effort to preserve some of the last remaining purebred strains of westslope cutthroats in the nation.

This year, the effort will continue in the Necklace Chain of Lakes in the Bob Marshall Wilderness. In late August, FWP biologists and technicians will treat the small lakes and a portion of the outlet stream with rotenone, a chemical that kills fish.

Rotenone is not hazardous to humans, but it prevents the absorption of oxygen across a fish’s gills. Death comes quickly. Rotenone was first used by South American and Asian natives to catch fish. It was originally derived from the roots of the derris plant, a pea species from Asia, and the lonchocarpus plant, from South America.

Rotenone will be hauled in by mules and applied to the Necklace Chain of Lakes. Biologists will cut the bladders of dead fish that rise to the top to prevent attracting bears and other birds.

The treatment can linger up to three months, biologists note. A chemical that neutralizes rotenone will be applied downstream from the outlets of the lakes to prevent harm to fish further downstream.

All told, the treatment will take a few days. The following spring, the effects of the rotenone will have dispersed, and the lakes can be re-stocked with purebred westslope cutthroat trout.

Prior to treatment, lakes in the conservation project were rife with non-native fish, including rainbow trout, rainbow-cutthroat crosses and yellowstone cutthroat crosses. The worry among biologists is that the continued hybridization of westslope trout with non-native fish eventually will wipe out the purebred cutts in the South Fork.

To date, Black, Blackfoot, Big Hawk, Clayton and Wildcat lakes have been treated and re-stocked. Many of the lakes are fishing well already, Boyer said, and some lakes already have natural fish reproduction just a year after being re-stocked.

Several other lakes are being treated through an effort known as “swamping,” where hundreds of purebred westslope cutthroat trout are added to a lake that contains hybrid fish. As the fish breed overtime, it’s hoped that the hybrid genetics will be squeezed out of the population.

All told, the entire project will cover 21 lakes in the Bob Marshall and Jewel Basin area. Biologists have also teamed up with the Backcountry Horsemen of the Flathead for packing services.

There are challenging waters ahead. Handkerchief Lake poses challenges because the outlet stream, Graves Creek, is short and flows into the Hungry Horse Reservoir. Biologists will have to be careful not to kill trout in the reservoir itself.

One the of the last lakes to be treated will be Sunburst, a large lake in the Bob Marshall that will need thousands of pounds of rotenone for treatment

A state hatchery in Coram recently received the final funding it needs to complete its construction. The Sekokini Springs Westslope Cutthroat Isolation Facility, located off the North Fork of the Flathead River near Blankenship Bridge, is one of two hatcheries in Montana where wild, genetically pure strains of trout are accepted.

The Northwest Power and Conservation Council recently approved about $1.8 million in funding for the state-run hatchery that’s been operating as an advanced conservation hatchery for more than a decade. The funding will be used over the next few years to finish the hatchery’s master plan, which calls for an outdoor pond and stream habitat to complement the indoor isolation facility.

While other hatcheries rely on the state’s only westslope cutthroat brood stock at the Washoe Park Trout Hatchery in Anaconda, Sekokini Springs will serve as a diversity resource for Montana waters that have lost genetically pure strains of westslope cutthroat trout over the years, said Fish, Wildlife and Parks biologist Brian Marotz, who helped manage the Sekokini hatchery since it was acquired by the state in 1998.

Sekokini Springs operated as a private rainbow trout farm for about 40 years on land leased from the Flathead National Forest. The state acquired the improvements, including a 60-by-40-foot building with concrete raceways, for about $70,000. The building was insulated to prevent condensation, damaged siding was replaced, and the artesian springs that supply the facility were capped and piping was installed to secure the water supply from airborne contaminants.

Sekokini Springs is used to quarantine juvenile cutthroat collected from wild sources. The fish are held in raceways, tested for disease and genetic purity, and eventually certified for use as a hatchery resource. FWP has identified about 50 genetically pure strains in the wild to draw from, mostly in South Fork drainages. Cutthroats in other drainages have been exposed to hybridization with rainbow and Yellowstone cutthroat trout strains.

Ironically, Sekokini Springs may have been a primary source for rainbow hybridization in the lower Flathead River system. The hatchery likely “leaked” fish over the years into the North Fork Flathead River, Marotz said. The hatchery now is entirely contained, and its waste water is disposed of through a special drainfield.

With the new funding, the building will be expanded, and two large, still-functioning ponds will be restored and converted into four ponds. Another pond will be created to grow wild feed. Grasshoppers and meal worms already are being cultivated at the hatchery.

BIG TROPHY BASS LIVE WHERE THEY ARE – BY BOB LUSK

BIG TROPHY BASS LIVE WHERE THEY ARE – BY BOB LUSK

That Could be Your Fishing Pond

It’s a dream many pondmeisters share. Young son or daughter, in the boat, enjoying the outdoors on your very own fishing pond. Birds flit above, something with scales spanks water’s surface not far from the boat.

For years, pond and lake owners carefully practice pond and lake management tactics. Proper fish stocking, adding cover or fish structure, fish feeding, pond fertilizing, dealing with runaway aquatic vegetation growth.

Long years, short years, go by raising the family, working hard at what you do. Stealing time to go fishing, and enjoying your pond and the outdoors.

Recently, there have been a number of pond owners who let us know if what they are doing is working and they are having a ball. Here are a few photos and some stories to share.

Johnny Tanner, III is a wonderful family man from Carrollton, Georgia. He takes care of a fourth generation grocery business while being the quintessential husband and father, doing what good men do. Of course, his bride takes pretty good care of him, too. She makes great chicken pie. I know that, first hand.

Johnny lives on a lake, plus has property with its own lake, a pet lake project dating years ago. Eight or ten years ago, Johnny renovated the lake just outside of town, restocked it with fish, and is doing everything he can do to have the greatest bass lake he can create.

He is exceptionally passionate about it. He believes in lake management. He believes in proper fish stocking. He believes in God and Country.

In the meantime, Johnny has spent countless hours doing what he can do with the lake behind his home. It’s a community lake with few rules, and few helpers. Over time, Johnny has added fish cover, especially Christmas tree brush piles. He has kept logs of his bass catches, tagged fish, and kept pretty good records. He has tagged fish weighing four to nine pounds.

He has a new story to tell.

Here are his words.

“On September 26, 2004, my son John (who is 8 years old and uses a baitcaster) and I were at Lake Carroll in Carrollton, Georgia about to go for a ride in the boat. I suggested we put a fishing rod in the boat. While we are out there we might as well fish a little bit. Fishing conditions were terrible but we put a rod in anyway. After an hour we had not caught anything. Winds were from the east at 15-20 mph. (Isn’t there a saying that if the wind is from the east the fish bite the least?) It was the day Hurricane Jean was coming up the eastern coast.

“John had picked out a 1/2 oz white spinnerbait. It was 7:00 pm and I cast it out 3 or 4 times trying to find some submerged trees. We had put out several trees in an area using the old pickle bucket method (May – June 1999 Pond Boss article X Marks The Spot). When I finally came across the top of them a bass hit and almost took the rod out of my hand. It was pulling the drag pretty good when I asked John if he wanted to bring it in.

“I handed the rod to John and immediately he said ‘Daddy the fish is going to pull the rod out of my hands.’ I repositioned his hands so the left hand was in front of the reel and the butt of the reel was in his stomach. It was a standstill for what seemed like an eternity. Finally, John started to get some line back on the fish as I moved the boat closer in her direction. John got the trophy bass closer and when she saw the boat, she went straight down. I thought for a minute that the rod was either going in the lake or going to break in half.

“My son John was straining with all he had.

“Finally, the fish came up and I almost had a stroke. I reached down and picked up the giant bass and brought her in the boat. The hook immediately came out of the fish’s mouth. At this point I had no idea how much this fish weighed because I had never, ever seen one this big.

“I had a set of Normark digital scales in my tackle box that went up to 10 pounds. When I put her on the scales, they started flashing like they were broken. I tried it again and again they flashed double zero. Finally, I let the fish down easily on the scale and watched them register 4 pounds the 5 then 6… .7… .8… .9… .then flash. I knew we had the bass of our lives. (My biggest bass ever is 9 pounds 3 oz. which I tagged and released in this lake).

“We got back to the dock and I had another digital scale that went up to 15 pounds. When I put her on those scales they registered an amazing 12 pounds and 4 ounces. I checked the scale when I got back home and it was correct to the ounce.

“The first thing John said is ‘Daddy, can my name be on the plaque,’ which I replied that he had done more work than I had so yes when we get her mounted we will both be on the plaque. What I didn’t tell him is that if I had known the fish was that big, he probably wouldn’t have gotten the rod.

“We kept her alive for a couple of hours in a cooler full of lake water and I debated whether to release her or keep her. I finally thought that in that particular lake I have records going back to 1994 of releasing between 150 and 200 bass that I have personally tagged. Their weights are from 4 pounds to 9 pounds. I also knew that a bass this big probably would have been in the neighborhood of 15 years old or more and had very little life left. So I decided to keep her. It was a tough decision, but when I saw the look on John’s face, and quickly reflected about my life, fishing with my Dad, and looked back at John, it was an obvious decision. I knew John may never see a fish this large again. We have always practiced catch and release and continue to do so.

“Lake Carroll is about 150 acres and full of Crappie and Gizzard Shad. The bass (even the big ones) have plenty to eat.

“Now, Little John and I have a fishing story that neither one of us will ever forget.”

Then there’s 30 acre Fin & Feather Club Lake in Atlanta, Texas. Gordon Pynes and his neighbors are conscientious about pond management in their pristine east Texas fishing hole. A number of people live around the lake and this club works to educate their members. Years ago, the lake was a vegetated mess full of algae and aquatic vegetation, when one of the members took it upon himself to become the caretaker. He had a pond management agenda, one that didn’t necessarily jibe with the rest of the membership. After all, they hadn’t done much pond management, except stocking a few fish now and then. The proactive member got their attention; they united and created a good pond management strategy. They limed the acid water lake to adjust the ph levels, fertilized the pond as needed, set up some fish feeders, and began culling slot bass.

The results on their fishery have been predictably amazing.

Electrofishing surveys have yielded bass larger than twelve pounds. Take a peek at the photos of recent fish collected, weighed and measured.

Then, there’s Stan Graff. You might remember the Pond Boss Magazine cover story several years ago. Stan has had hundreds of gar removed from his 30 acre lake in northeast Texas. With fish feeding stations, and moderate aquatic vegetation control, the program has yielded quick results. Slot sized bass, without competition, have grown to look like footballs with a mouth.

You can’t wipe the grins off the guys’ faces. Fishing is fun again at Flagg Lake.

Everyone enjoys looking at giant fish. But, knowing the effort it takes to provide the best habitat, best forage fish, best genetics and best pond management to create a moment in life is staggering to think about. Everything must come together at the right time, at the right place. Even when the stars line up, there’s no guarantee what you do will work. But, here are three shining examples where pond management has paid off.

WHY FEED YOUR FISH – BY BOB LUSK

WHY FEED YOUR FISH – BY BOB LUSK
Thursday, December 09, 2010 at 10:02pm

Pond Boss subscriber Shane Howell of Dallas stepped on rocks near one of five shoreline feeders surrounding his spanking-new 30-acre Oklahoma lake. He pushed the timer button, then stood back to watch the action as thousands of tiny protein-laced nuggets pelted the water’s surface.  

Hundreds of young bluegill and fathead minnows welcomed the offering, and quickly dispensed with the free meal, in a frenzy fit for starving piranha.

“We designed and stocked this lake to become a trophy bass lake,” Howell said with a smile, “and part of our management plan is to feed the baitfish.”

Feed the baitfish? What gives? Why put protein pellets in the water that the top-end gamefish may or may not eat?

Those are questions many fish pond owners ask themselves. Should you feed your pond fish? Nationwide, biologists disagree on the issue of feeding pond fish.

Proponents point out that high-protein pellets supplement the natural food supply in a fish pond and directly boost growth-rates among certain species, while indirectly improving the rates on some others. Rainbow trout, for instance, can be fed like so many barnyard chickens.

Then again, you might hear some negatives, such as: It’s a commitment. The cost is prohibitive. Feeding causes fish to congregate, altering their behavior. It’s like welfare. Pellets aren’t “natural” in a pond. Water quality is changed, forever.

So’s which side is right? Here’s how to decide the issue for yourself.

If you want to expedite growth-rates of bluegill, catfish and trout, or if you want to increase standing crops of fish in your pond, the answer is simple. Feed the fish.

For every two pounds of protein-rich, pellets (I recommend the floating variety) a group of fish consumes, those fish collectively gain a pound. The fish in your pond now weigh one more pound than before. Two pounds of feed, a pound of fish, and so on.

Let’s look a little deeper into the numbers. The best fish foods cost about 30 cents a pound. So, 60 cents of feed grows a pound of fish.

Stocked any fathead minnows lately? Priced at $10 a pound, fathead minnows can not compete with commercial pellets when it comes to feeding your pond fish.

Trying to grow huge largemouth bass? So many Pond Boss readers are.

Ol’ Bucketmouth won’t dare eat a prepared, pelleted diet. Heck, sitting atop the food chain, with a mouth big enough to swallow a cantaloupe, bass can eat anything in the pond, especially living critters. Bass snub tiny little pellets. Largemouth have bigger fish to fry, so to speak.

But what does a largemouth love to eat? Bluegill. And Mr. Bluegill loves to eat pelleted fish food.

Aha. Feed the fish that feed the bass. By so doing, you have created your own miniature food chain.

A well-managed pond, covering half a surface acre up to three acres, can grow and maintain 200-to-300 pounds of channel cat or trout along with 200-to-300 pounds of forage fish, per surface acre. That’s with an abundant supply of bluegill and other forage species. But, if you were to add high-protein fish food, the same pond can easily double that production.

Arguments arise. Is feeding a commitment? You tell me.

Much of the U.S. has at least 200 days of growing season, slightly less in the Upper Midwest and northern New England, fewer still in Canada. For the sake of creating a model feeding program for a mythical pond, let’s just say you intend to feed only three or four days, maybe five days some weeks.   

Your fish consume all of what you feed, say four pounds a day per surface acre of water. Over the course of 150 days, you feed 600 pounds of feed. Those 600 pounds of feed yield 300 pounds of fish, doubling your ponds natural production capabilities.

Do the math: Six hundred pounds of feed, at 30 cents a pound … $180. Less than $200 to put 300 pounds of weight on your fish. Cheap. I consider that a bargain.

Can you feed more? Sure, but be careful.

Two pounds of feed yields a pound of fish, but there is a balancing act to consider. For every pound you feed to the fish, there’s a pound of nutrients, some converted to energy, some processed by the fish and expelled into the water as waste. When waste dissolves in your pond, the water must process it.

Too much feed can result in too many pounds of fish, too many pounds of waste, and ultimately, problems with your water quality, if your pond water can not work with Mother Nature to clean up the extra mess. In extreme cases, I have seen overfed ponds end up with massive die-offs related to poor water quality and low levels of dissolved oxygen.

Feeding catfish? Grow Mr. Whiskers to two pounds, then catch and eat the little darling. Want bigger catfish? Stock lower numbers in the beginning. Want to name them? Stock fewer yet.

In short, do not overfeed, or plan on removing a few fish as you go along. Otherwise, your fish and your water quality will suffer.

Here’s one of my Rules of (Wet) Thumb: Never feed more than 10-to-20 pounds of floating fish food, per surface acre, per day.

Theory can get a little complicated, since young, fuel-burning fish, converting at a rate of 2-to-1, will eat 3 percent of their body weight per day during the growing season. So, keep your feeding program simple.   

To keep it simple, I recommend that in most sportfishing ponds that you feed no more than twice a day, for brief durations, once in the morning, once in the late afternoon. Feed only what the fish will clean up 10-to20 minutes. Otherwise, you’re wasting your money to watch the wind and waves carry your pellets to the other side of the pond.

Either way, keep your feeding program simple and consistent. Feed from the same place, same time, each day. As your fish grow, you may discover that where you once were feeding for production, now you are feeding to maintain. That’s when you reach decision time.

Do you feed the same amount of feed, to the same number of fish that stay the same size? Or do you reduce numbers to increase individual size?

Some biologists contend that feeding fish is akin to welfare. It creates an artificial environment. Point well taken.

Granted, when you offer pellets to a fish, it tends to leave the real world of fish-eat-fish. But it’s a balancing act. The fish you feed are not necessarily taken out of competition, but they compete less with other fish for natural prey in your pond.

In that regard, feeding pellets makes “more” natural food, to be distributed among all fish, not just a few. This increases a pond’s ability to support fish — the very point of pond management.  

Critics say a feeding station tends to congregate fish, to pull them away from their natural underwater home. Absolutely. When the dinner bell rings, fish come from as far as 100 feet away.

Bluegill and minnows surface to attack the pellets, then disappear just as quickly as they came. Hybrid stripers can put on quite a show of force when they gulp down pellets. Bass take note, too. A big bass will not be attracted to the pellets, but to the creatures partaking of the free offerings.

After all, bass won’t turn down an easy meal either. Bluegill eat fish food; bass eat bluegill eating fish food. In nature, there’s always a payback.

Too many fish can jeopardize water quality, so feed less or reduce the number (or size) of the fish. One option is adding an aerator. The tiny air bubbles bursting at the surface help Mother Nature to combine oxygen and sunlight in helping to flush or “burn” the waste products.

Rule of (Wet) Thumb: Buy good fish food. Read the bag tag, make sure the feed contains at least 28-to-32 percent digestable protein. Read the ingredients, looking for the words “fish meal.” If you don’t see those words, don’t buy the food.

For best results, use only feed intended for fish. Feed dog food to dogs, monkey food to monkeys. Your fish deserve the real meal deal.

When it comes to feeding, pond owner Shane Howell has it figured out.

“Since our goal is to grow trophy bass, and this is the first year our lake has been stocked,” he said, “we decided to grow as much baitfish as possible, to grow the biggest bass possible.”

Howell knows that it takes at least 10 pounds of baitfish for his bass to gain a pound. In his fishing hole in south-central Oklahoma, five feeders pitching out 10 pounds of feed each day will set the buffet table for his bass to grow as fast, and as large, as they can.

Howell has done the math … 10,000 pounds of feed over 200 days will produce an extra 5,000 pounds of baitfish for the 1,500 Florida bass fingerlings he recently stocked. That’s an extra 170 pounds of baitfish per acre, (above what the lake produces without feeding) that will make his bass grow to large sizes much more quickly than a “normal” lake of similar size.

The irony of Shane’s program is that when he buys $3,000 worth of feed, the largemouth will be growing rapidly, without eating so much as one pellet.

‘AMBUSH’ IS THE WRONG WORD – BY RALPH MANNS

‘AMBUSH’ IS THE WRONG WORD – BY RALPH MANNS
Thursday, January 27, 2011 at 5:37pm

Ralph Manns is a trained fisheries biologist and contributing writer for several fishing magazines. He resides in Rockwall, Texas.

When largemouth bass feed actively, they move. Underwater observers, scientific experimenters, and electronic trackers all report the same things: black bass hold inside or near to cover when they are inactive and resting. When they are actively feeding, they move outside thick cover and usually travel along edges.

The slim, muscular, and streamlined shape of bass is best suited to make short dashes after forage fish. It is less well designed to ambush forage fish by lying hidden and camouflaged inside cover. Predator fish that routinely feed by ambush usually have several characteristics in common. They are bulky, camouflaged, sit on the bottom, and move only inches when they strike. Moreover, ambush feeders normally have big mouths and heads and relatively small bodies and few muscles because they move little and often must wait many days between feedings. Sculpin, rockfish, halibut, and sole are typical ambush predators.

Experiments in which bass were given chances to feed inside and outside cover show bass forced to live inside thick cover are unable to chase forage fish and are forced to use ambush tactics. These bass catch few forage fish, grow slowly, and may even starve if forage fish aren’t abundant. Although they sometimes ambush forage fish, ambush is an inefficient tactic for bass.

Bass that can leave cover to cruise individually or in small schools along edges of thick cover do so. They startle individual forage fish and scatter forage fish schools. Forage fish that dart the wrong way or dash too near another bass were eaten. Big bass expert Doug Hannon calls this tactic “flushing.” The tactic is suited to bass’ ability to cruise at slow speed and then to accelerate rapidly to strike vulnerable forage fish a few feet away.

When forage fish aren’t overabundant, cruising bass encounter and have chances to catch many more forage fish than ambushing bass. Studies show bass feeding along the edges of thick cover catch enough food to grow and remain healthy.

Scuba divers, me included, have watched bass that were immobile inside cover and apparently asleep. These fish didn’t feed, even though edible-size forage fish were within inches of their mouths. These inactive bass also refused fishing lures presented within inches of their noses and were almost impossible to catch-unless something aroused them from their torpor before the lure passed by. Electronic trackers frequently report that bass that hold for long periods in the same place aren’t usually catchable.

In contrast, bass that held near the edges of cover and moved back and forth were occasionally tempted by fishing lures that were placed nearby. They were also more easily aroused to active status by repeated casting. These bass are usually neutral or semi-active. Neutral bass tended to hold near other bass, but don’t synchronize their movements or hold close together. Scientists call such groups “aggregations” rather than schools. Forage fish often hover nearby, but stay at least 3 feet away and remain constantly wary. Neutral bass will strike forage fish that blunder too close and often drift around rather than holding in one place only. Electronic trackers often report these local wanderings, but anglers find only precisely placed casts interest such fish.

When bass want to feed actively they form schools with bass of similar sizes and swim off together. They cruise fairly steadily along edges of cover (into open water if there are many bass and shad are abundant) to flush forage fish. These are active, catchable fish if anglers can locate them, predict their direction of movement, and put a lure in front of them. Nearby forage fishfish know when bass were preparing to feed and immediately move well out of range. The bass move away looking for forage fish that haven’t seen them coming.

The idea that bass feed by ambushing forage fish apparently resulted from some 0 observations and assumptions. Bass are inactive or neutral most of the time. While inactive, they frequently rest inside thick cover. It they aren’t digesting food, too sleepy, and totally immobile, lures flipped right on their noses may be taken. They also may wake up it aroused by repeated casts. Thus many bass are caught in cover where ambush is the most likely tactic. Moreover, moving bass still may stop periodically at places where cover or structure stops, starts, bends, or changes. Bass taken at these locations may seem to ambush lures or forage fish, even though the bass aren’t actually hiding there.

Bass usually don’t move only one way. Lunker bass monitored by Texas bass-tracker, John Hope, moved almost constantly when active, but they patrolled to-and-fro along the edges of cover or break-lines. Anglers who “hole-sit” on edges, bends, and points of weed beds or other cover during feeding periods may encounter several schools of passing bass or contact the same school several times as it passes back and forth. This can create an illusion that the feeding bass aren’t moving. Active bass also move along cover edges anglers can’t see. Fairly open pathways often exist under thick weeds and seemingly impenetrable brush. Fish that are apparently caught “inside” such cover may be moving along relatively open edges. It’s hard for anglers to tell the difference between a bass that was caught while holding inside or under a bush to “ambush” forage fish and another that was moving back and forth at the same depth under a cluster of bushes.

Truly inactive bass tend to sleep alone. When bass anglers take several fish during consecutive passes by the same bush, they likely have found a spot that fish are moving through rather than resting fish. Inactive bass seldom school, don’t strike readily, and don’t move about rapidly enough to quickly replace bass that were caught moments before.

The belief that bass “ambush” their prey apparently worked its way into bass fishing lore because many outdoor writers prefer to use aggressive, action-packed words. The image of a bass hiding behind a rock to “ambush” unsuspecting prey makes bass seem vicious, like a western movie “back-shooter.” and therefore a more worthy opponent. “Chasing” or “flushing” tactics just don’t make bass seem as tough and exciting. But “ambush” is the wrong word to describe how bass usually feed. Bass ambush if opportunity presents itself, but this is not their preferred feeding tactic.

To catch more bass, anglers must know how bass really behave. Actively feeding bass usually move in small groups. They usually don’t hide inside cover thick enough to block their vision and/or hinder attacks. Cover is cover for forage fish. Forage fish hide in it to escape bass. Bass use cover for the same reason. They move into it to rest undisturbed by larger threats like yellow catfish and anglers, rather than to feed. Bass are most often caught along the edges of cover because forage fish gather there and are more easily flushed there.

To feed effectively and often, bass move out of thick cover to seek, startle, or flush forage fish along the cover edges in ponds and reservoirs. Most pond owners will see and confirm this fact for themselves if they sit at pondside, as I do almost every day, and watch bass using Polaroid glasses.
