If you’ve ever driven by a lake that has brown water resembling ice tea then you’ve seen a pond with tannic acid. Most of the time tannic acid is just an aesthetic issue. However, sometimes it can be more serious. This client was about to stock 6,000 3-4″ bluegill before we checked his water quality. The water didn’t even hold 1 milligram worth of oxygen. This would have been a death sentence for the bluegill and an ill-spent $3,600. To help reduce the tannins in the water and improve oxygen levels we applied aglime. Aglime contains high amounts of calcium which raises the pH levels and alkalinity.
With the aglime applied we will give it a few months to start changing the soil and water characteristics. Although this is not a good situation it could have been much worse if fish were stocked. The owner isn’t on the property at all times so the fish would appear to go in healthy but by the time he was out next the buzzards would have cleaned everything up. If you ever face a tough situation with your fishery give AES a call. We have plenty of experience and creativity to solve problems.
Pond Survey Without Electricity?
99% of the time we can figure out a way to get our shock boats into a pond but there will be a few forever out of our reach. Using standard electrofishing techniques is the most comprehensive way to survey a pond. This will give us direction when it comes to fish stocking and other pond management tasks. Even without electricity we can use other techniques to get a good idea of what’s happening. When ponds are in balance or out of balance there are certain things to look for. Ever heard a friend say they catch only huge bluegill and small bass? Feel safe to bet your week’s paycheck he has an out of balance pond. Ponds that are in balance will have many different sizes of bluegill along with healthy bass.
Angler surveys and seine netting are the most commonly used techniques we use to survey a pond without our shockboat. Any college graduate did a thousand seines before they received their hard earned diploma. Angler surveys are a fancy way of saying we get paid to fish. A rod and reel are the most common tools. AES has a select few employees that think they are sophisticated and insist on fly fishing. Once fish are seined or caught the same inventory procedure follows as if we were on the shock boat. Bass will be weighed and measured for length. Bluegill will be measured for length. Any other species of interest such as channel catfish or black crappie will be inventoried as well.
Although not electricity, a rod and reel can be revealing in the right hands. At AES we know budgets are fluid so an electrofishing survey may not be in the cards. However, we encourage property owners to fish and figure out their own waters. If owners are unsure send pictures and accurate measurements for AES to look at. We want to help everyone to the best of our ability achieve their goals.
March 19th-23rd Electroshock Recap
Another great week is in the books for the shock team. Erratic weather continues to plague the Southeast but the fish are still making their migration towards the shallows. Luckily the nighttime temperatures are not dropping drastically so the water temps are not moving much. This week our average water temperature was about 54 degrees which is great for shocking pre-spawn fish. However, farther south we are shocking some post-spawn fish. We can blame the 80 degree February blast for that.
Weekly fishing tip- Stay off the bank. Fish are pre-staging about 15 feet off shoreline. Work spots with brush, tree tops, or rock. Rolling some big females that are holding tight to cover. Smaller males are cruising the shoreline or preparing beds. Keep it simple lure wise. Texas rigged soft plastics or smaller jigs are the best. Floating worms like the Zoom trick worm in bubble gum or merthiolate are great pre-spawn colors. Bright colors traditionally do best before the spawn when fish are aggressive.
This coming up week we will be shocking along I-20 in East Georgia and far Northwest Georgia. The weather still looks crazy with a brisk start then a huge mid-week warm up. We hope this warm up will be the trend but March is the most volatile month in weather as we are finding out.
Middle Georgia MossBack Habitat Install
The calendar doesn’t agree but it’s spring in Georgia. This means ponds are starting to come back to life. Whether it’s fish stocking or electroshocking we are getting busy at AES. When we shock lakes each report comes with custom recommendations from our senior biologist. Habitat is usually a key component. Why stock thousands of dollars of bluegill and golden shiners in a pond without cover? They will just get ate as soon as they hit the water.
Today’s ponds were the final phase of habitat installation. To ease budget concerns we will break up habitat projects over two to four years. Doing it over a long period of time allows the pond owner to give us feedback. Sometimes in year three the owner might want to add a Texas Hunter fish feeder and want to drop some MossBack rootwad kits near the feeder.
If your pond or lake is lacking cover and full of small bass give us a call. We love to work with concerned property owners. Budget shouldn’t be the reason you and your family/friends are not enjoying your pond. We know how to bring the most value to you.
Ever wonder why the Midwestern United States grows such huge deer versus other parts of the lower 48? A little hint is good dirt grows big deer. The same concept applies for growing trophy bass. Unlike the Midwest, here in the Southeast we are not blessed with good dirt. Being famous for having red clay isn’t a huge source of pride for most lake owners. Luckily liming is an easy and effective way to improve water quality. Liming does a lot of good things for your pond such as raising alkalinity and reduce pH swings. High alkalinity will make fertilizer more effective and small pH swings will make the aquatic environment stable.
With deer food plots landowners typically apply one ton per acre every year. As lake managers we apply four to six tons per acre. This seems like overkill. That is exactly what we want because at this rate you only have to lime every three to five years. Some will luck out and be good for many years. Factors such as watershed size effect the rate. Also years with flooding will wash out lime quickly.
Liming a lake is a straight forward process. First we will get lime brought in and dumped near the shoreline. We will bring our lime barge to the lake. No boat ramp is needed. There just needs to be an area with clean bottom and good drop off. Of course we need plenty of room for the trailer and trucking company.
A front end loader is needed to load our barge. Typically one bucket is enough. We require the loader to be 4 wheel drive and at least 20hp. We’ve used small loaders and they will tip over or break due to lime’s density.
The final step is to blast the lime off. On our barge we have a 2in trash pump that produces 213 gallons per minute. With this flow rate we are typically able to move eight to ten tons of lime in a hour.
Typical lakes only need 24-50 tons so we can get your job done in an afternoon. Winter is the time to get this done so when it warms up you will be back to enjoying your lake. Call us now to get ahead of the spring rush.
Threadfin Shad Kill
As temperatures continue to plummet in the Southeast many lakes are reaching unheard of temperatures. Most fish will hunker down in the deepest portion of the lake and ride out the storm. However, some fish are more susceptible than others.
A key food source that becomes vulnerable in extreme cold is Threadfin shad. Around forty-five degrees is all threadfin can take before they start to die. They will search the depths trying to find suitable water. It’s common for threadfin to suspend in a certain portion of the water column. Whenever visible ice forms on the surface of the lake a shad kill becomes a real possibility. If your lake is small you can make a quick visible inspection to look for dead shad. If your lake is large you can also make a visual inspection but also be on the look out for seagulls or vultures picking off the dying shad.
If a shad kill is seen call our office and place your order for restocking. Shad stockings occur in April and early May. There is a limited amount of shad from suppliers so it’s critical to place your order early. Getting the lake electroshocked to inventory the shad population will show us how your population fared. Some luck out and have a partial kill while others loose the whole population.
Ageing a bass is one of the best ways a biologist can gauge the health of a bass. In the Southeast we use the otolithes to determine age. In the North or where there are defined cold and warm seasons scales can be used to determine age. This is a quick guide on how otolithes are retrieved and aged.
Once age has been determined we can now implement strategies to improve the fishery. Most lakes have never been managed so they are full of old, stunted bass. In most cases the best option is to drain the lake and start over. It is possible to get these bass healthy again but it may be too late. Bass have a lifespan of eight to ten years. If a bass is stunted at six years old then pouring $2,000 of bluegill in the lake is futile. During an electrosurvey we take otolith samples so call us today and get booked.
Electrofishing Outside of the Southeast
Although the bulk of our business comes from Alabama, Georgia, and South Carolina we are more than capable to survey lakes outside of our home range. With the number of years Greg has been in the pond management industry he has forged a reputation of building the finest fisheries so naturally word has spread. The shock team makes a road trip to Arkansas, Louisiana, and Mississippi in late spring and another trip to Illinois in early summer. Shocking in Florida is an emerging area for us as well. There are many companies in Florida than manage vegetation but few provide fisheries services.
Even if you do not think you’re close to the home office give us a call. Many times we can complete fish population surveys on multiple ponds in an area to reduce the travel cost.
Pop Eye Disease
Did a little eye surgery today and removed these ocular nematodes from bluegill eyes. They had Pop Eye disease. Only cure for Pop Eye disease is ridding the muck from your pond. If you see Pop Eye disease in your pond, then contact us for an aeration quote.
