Pond Fish Management & Stocking


A healthy fish population in a San Marcos, Texas (TX) area lake or pond, can help provide insect control, recreational fishing opportunities, and overall ecosystem balance. Our experienced Fisheries Biologists will help you define a customized management objective and then take your project from beginning to end. Whether you want a simple self-sustaining fishery or Trophy Largemouth Bass, proper planning is key.


Pond Fish Stocking Service


Stocking decisions should be based on your objectives and the level of pond management you expect to use. Many options exist. Sterile grass carp can be extremely effective aquatic weed and algae control tools. Many people enjoy a few hybrid striped bass stocked into private ponds for trophy fishing or to control overcrowded small fish. Fathead minnows are excellent forage for predatory fish. Consult with one of our staff biologists for a quality stocking recommendation.

If you’re building a new pond, or currently have a balanced population, several steps can be taken to avoid problems. DO NOT add additional wild fish or fish from someone else’s pond. Wild fish from streams or other ponds may not be genetically pure and may carry diseases or parasites. Remember, you want a fish balance, which will allow you to achieve your objectives for the pond. The fish you stock are a long-term investment. Don’t make a mistake that could haunt you for years; stock fingerlings from a reputable source. We guarantee our fish are healthy or we will replace the fish or give you your money back.​


Electrofishing Surveys


Electrofishing is the most scientifically advanced method of analyzing fish populations in freshwater lakes.  Performing a fish survey provides a fisheries biologist with an accurate and safe means to sample a fishery population. This specialized equipment sends pulses of direct current into the water. This procedure stuns the fish that are swimming in the electrical field around the boat.  We can then collect, weigh and measure large numbers of fish without harming them.  This data provides us with important information including population density, species diversity, fish health, and Relative Weight.   Water quality information, habitat, and depth surveys can also be collected at the same time.  These factors are all used to create a customized pond management strategy, for your San Marcos, Austin, Texas area pond or lake.


Fish Habitats


A pond with the right amount of structure provides more fishing enjoyment than a structure-less fishing pond. Structures placed in the right locations are fish magnets that dramatically increase fishing success. Fishery habitat improvements can also result in larger fish when done properly. A bass has to eat 10 lbs of fish in order to gain one pound. Small 1-inch bluegill generally weigh 5 lbs per 1,000 fish thus the bass would have to eat 2,000 bluegill to gain one pound. Adding dense cover will allow the young bluegill to survive and grow for an additional month or more. In just one month, bluegill can quickly grow to 20 lbs per 1,000 fish so now a bass only has to eat 500 bluegill to gain a pound. This means much less energy is expanded allowing energy for growth. This is a simplified example but indicates how protecting the small bluegill is essential for good bass growth. Contact us for more information regarding Fisheries Management & Fish Stocking.
