Stocking & Harvesting Recreational Fish Ponds

Proper stocking and harvesting of recreational fish ponds is paramount to the long-term success and enjoyment of recreational fish ponds. Some pond managers attempt natural stocking and/or establishing a number of different species within a pond. Research, however, shows it is critical that only the proper species and numbers be stocked and harvested in a recreational fish pond.

A surprising amount of research has been done to establish the proper prey and predator species and stocking rates for establishing recreational fish ponds in the Southern United States. Many different combinations of predator and prey species have been tried for recreational fish pond stocking. The best strategy is stocking largemouth bass as the predator species and bream as the prey species. The proper ratio to stock is a 10:1 bream to largemouth bass ratio. These species at the proper ratio will allow for good, long-term fishing.

If good fish growth and proper pond balance are to be maintained, the pond manager must initially determine whether or not he plans to maintain a long-term fertilization program before stocking his pond (see HGIC 1710, Fertilizing Recreational Fish Ponds).

If the pond is to be fertilized, it should be stocked at a ratio of 1000 bream to 100 largemouth bass per acre. If the pond will not be fertilized, it should be stocked at a ratio of 500 bream and 50 largemouth bass per acre. The bream species stocked are a ratio of 3:1 bluegill to shellcracker (red ear sunfish). This bream ratio allows for more efficient food selection within the pond since they feed on different organisms and an opportunity to enjoy a greater variety of fishing opportunities. If the pond manager is unsure as to whether or not he will fertilize, it is best to stock at the unfertilized pond stocking rate of 500 bream and 50 bass per acre. Overstocking of a pond can rapidly lead to poorly nourished fish, poor fish health, and a reduction in reproductive success, which can lead to an out-of-balance fish pond that will need renovation (see HGIC 1713, Use of Rotenone for Management of Fish Populations). Research has shown that the minimum size pond that can be stocked for long-term production of quality fish is a half-acre. For ponds less than a half-acre it is best to stock single species such as channel catfish or hybrid bream that can be fed a commercial diet.  These ponds will need to be harvested and restocked every few years.

Fish may be purchased from licensed private fish hatcheries. Bream are stocked in the fall or winter; largemouth bass are stocked the following spring or early summer. The bream are stocked early enough so they can obtain a large enough size not to be preyed upon by the bass the first year. The largemouth bass are stocked in the spring so they can obtain a large enough size by the following spring to reproduce.

The initial harvest of fish should start in midsummer the second year after the largemouth bass stocking. Largemouth bass reproduce only once a year, so it is extremely important to allow for the initial bass reproduction before initiating any fish harvest.

It is important that pond managers attempt to regulate the amount of fish harvested from the pond on an annual basis. The proper harvesting program will produce good fishing for a number of years. It is important to follow the harvesting recommendations and not underfish or overfish your pond.

Underfishing and overfishing can both lead to an out-of-balance fish population characterized by small, stunted fish.

Annual Fish Harvest

Bream Bass
Fertilized Pond 75-100 lbs/acre/year 18-25 lbs/acre/year
Unfertilized Pond 30-30 lbs/acre/year 10 lbs/acre/year

Pond managers should remember that bream reproduce several times a year while largemouth bass reproduce only once a year. It is important to remove bream each year so that the population remains at a healthy size and stunting of the bream population does not occur. Correspondingly, over_harvesting of largemouth bass can lead to reduced removal of bream by bass and a large population of intermediate-sized, stunted bream that are still able to reproduce.

Fish harvest should be spread throughout the year, and no more than a quarter of the total annual harvest should be removed in any single month. During the first harvest season, pond managers may wish to slightly under_harvest the bass so that the predator species population can be properly established.

Other Fish Species

Only a select few other fish species may be stocked in the traditional bass/bream recreational fish pond. One hundred channel catfish per acre may be stocked. Channel catfish usually do not successfully reproduce in traditional recreational fish ponds, so they can be harvested and restocked without a significant effect on the bass and bream populations. Most commercial fisheries recommend 8-10 for new ponds or up to +35 per acre for severe weed problems.

Triploid grass carp is an organic, non-chemical way to control weeds in a pond. Since they have three sets of chromosomes and are sterile, they do not reproduce and do not have significant effects on the traditional populations.

Triploid grass carp are sterile and do not reproduce so will not affect the other fish populations.

Tilapia, a tropical species, can be stocked for aquatic weed control for additional forage for bass. Tilapia do reproduce but are a tropical species and generally die during our cold winter months. Tilapia stocking rates are between 300-500 per acre. They are excellent for controlling some aquatic vegetation problems and food for larger fish in the pond.

Golden shiners, a type of bait minnow, are frequently used in recreational fish ponds. Golden shiners can grow to a large size and rapidly reproduce, causing major problems in the fish population, and it is highly recommended that they not be used in recreational fish ponds.

Another minnow that may benefit the overall production of the pond is the Gambusia minnow, commonly referred to as the “mosquitofish” They can be a major asset to the pond because of their location on the food web. Their primary function is serving as a way to control mosquito larvae. Their primary diet is mosquito larvae, which helps with the pond’s overall health. They may change to a different diet as they mature, but most young ones consume mosquito larvae.

During the spawning season (about 57 oF), they have a gestation period of about 15 to 30 days. They are livebearers, meaning they give birth to small fish resembling adult fish. One female can produce about 50 to 60 offspring, which are rarely completely consumed and add value to the pond. They are heavily preyed upon as you, so they rarely overpopulate a pond. The maximum length of an adult is less than 3 inches, and their lifespan is 1.5 to 2 years. Recommended stocking is 1000 fish per acre.
