Sport fishing is a popular recreational activity among Missouri pond owners (Figure 1). Developing a farm pond for fishing requires several important decisions, including where to get fish; what species to stock; how many, what size and when to stock. Ponds stocked with incorrect combinations of fish can quickly develop unbalanced populations that will become a problem.

Small farm ponds and lakes are not natural environments, so they must be carefully managed. Successful pond management involves a combination of practices that promote a healthy and productive pond ecosystem:

Sources of fish

A variety of private commercial producers produce fish for pond stocking. Deal only with reliable fish hatcheries or producers to ensure fingerlings are healthy and to avoid introducing undesirable fish species, parasites or diseases into your pond. Consult MU Extension, Lincoln University, the Missouri Department of Agriculture or the Missouri Department of Conservation (MDC) for recommendations on reliable producers. The Missouri Aquaculture Directory, published by the Missouri Aquaculture Association, provides a list of reliable producers (see Additional resources).

MDC requires that pond owners keep receipts as proof of purchase for fish purchased or obtained from a private fish producer. Only species listed on the Missouri Approved Aquatic Species List may be stocked (see Additional resources).

Tips for selecting a fish supplier

Fish stocking strategy

The choice of fish to stock will depend on your goals and available resources. Stocking can be divided into two general categories. Ponds of 1 acre or larger can be successfully stocked with a combination of largemouth bass, bluegill and channel catfish (Figure 2). In ponds smaller than an acre, bass and bluegill populations can be hard to manage. Stocking a single species such as channel catfish or developing a hybrid bluegill or sunfish fishery in combination with channel catfish are better options for small ponds. These species will have to be restocked regularly as they are harvested (Figures 3 and 4).

Stocking recommendations for establishing a balanced sport fish population are based on information from years of research by the Missouri Department of Conservation. For the best fishing, you must stock these fish in the proper ratios. Incorrect fish stocking may result in unbalanced fish populations and affect the production of harvestable fish.

Estimating pond size

You need to know the acreage of your pond to determine the recommended numbers of fish to stock. MU Extension publication G9474, Pond Construction and Management Considerations; MDC’s Missouri Pond Handbook; and other publications listed under Additional resources provide information on estimating pond size.

Consider the following fish stocking options when determining what types of fish you want in your pond.

Stocking fish for ponds 1 acre or larger

Largemouth bass and bluegill are a common combination for stocking ponds in Missouri. A healthy pond has a balance of predator and prey species, and bass and bluegill provide this balance better than any other combination of species in ponds larger than an acre. This pairing also allows you to add a few other species, such as redear sunfish, channel catfish and fathead minnows, to provide additional fishing opportunities and supplemental forage. Grass carp may also be stocked if the pond has an aquatic weed problem that needs to be controlled.

When stocked at recommended rates and properly managed, these species can provide years of good fishing. The recommended rates allow for healthy fish growth and provide enough fish to allow for taking some without hurting your pond’s future fishing (Table 1). Stock all species except bass in the fall, when the pond is half full and filling. Stock bass the next spring.

Fingerling sunfish, such as bluegill and redear; catfish; grass carp; and fathead minnows can be stocked in the fall and early winter. Stock 500 bluegill sunfish fingerlings per acre or, if desired, a combination of 350 bluegill and 150 redear sunfish per acre (Figure 5). You can also stock 100 channel catfish fingerlings, 4 to 6 inches long, per acre if you are interested in adding another species to the pond for angling. Fathead minnows can be stocked at 3 pounds per acre to provide an additional source of forage.

Stock 100 largemouth bass fingerlings per acre in May or June of the next spring. The sunfish and fathead minnows will be getting ready to spawn at that point, which will help ensure prey are available for young bass. Largemouth bass prey on a variety of species, including small fish, frogs, crayfish and insects. Bass will spawn once a year in ponds and small lakes in Missouri. Where prey are plentiful, bass will grow rapidly, reaching 3 to 5 inches their first summer and up to 15 inches after three years. In Missouri, they reach spawning size at 10 to 12 inches, usually when they are between one and two years old.

Crappie are also a popular sport fish, but they rarely thrive in small ponds and lakes and should generally only be added to lakes larger than 50 acres. Crappie compete with bass for food, and they spawn earlier in the spring than bass and bluegill, meaning they will compete with young fingerlings for forage. Additional forage, such as fathead minnows, must be added continually to avoid stunting the growth of crappie and largemouth bass. Bluegill spawning will be unsuccessful if too many predator fish are stocked in the pond. If you stock crappie, the best plan is to stock hybrids of black and white crappie so their reproduction will not outpace the small bass.

Stocking fish for ponds 1 acre or smaller

Soil fertility, stocking rates and supplemental feeding

Stocking considerations should include the soil fertility of the surrounding pond watershed and whether supplemental feeding will be necessary. This guide does not provide details on such specifics, so you should consult a fisheries biologist or extension specialist if you are interested in increasing stocking rates and supplemental feeding fish. Alternative fish stocking strategies can work but also require professional advice. Each situation is different, and no single recommendation can cover every case.

Stocking combinations of largemouth bass and sunfish is less successful in ponds smaller than an acre. Sunfish populations increase too fast for any individual fish to grow to a harvestable size. Additionally, bass can easily be overharvested in small ponds and do not provide enough pressure on sunfish populations to keep them in check. However, several stocking options work well in these smaller ponds if managed correctly.

For ponds managed specifically for recreational fishing, you can stock 50 largemouth bass, 50 channel catfish and either 500 bluegill sunfish or a combination of 250 hybrid sunfish and 250 bluegill per acre. Catfish will need to be restocked regularly. You can also stock fathead minnows for added forage at 3 to 5 pounds per acre. Alternatively, you can stock 150 redear sunfish instead of the bluegill.

Channel catfish can be stocked in smaller ponds at 200 fingerlings per acre, but they will require supplemental feeding. Hybrid sunfish stocked at 500 fingerlings per acre are also an option, particularly if the pond will be fished frequently.

Conclusion

Properly constructed and managed ponds and lakes are valuable resources that can provide opportunities for aquaculture production or recreational sport fishing. An understanding of basic pond and fisheries ecology can help you accomplish your management goals.

Key considerations when planning your fish stocking program are the expected fishing intensity and the fertility and condition of the pond. The size of the watershed is also important; ponds should have 10 to 20 acres of watershed for each surface acre of water. Ponds with smaller watershed-to-surface-water ratios are harder to manage because water runoff is inadequate to keep the pond filled at crucial times of the year.

In a properly managed pond, natural spawning and growth will replenish bluegill and bass populations diminished by fishing. Catfish and hybrid sunfish will not reproduce in ponds, so they will need to be restocked annually or as they are harvested. Good fishing is not guaranteed, but careful management greatly improves the chances of it. Once a pond is stocked with the proper ratio of fish, maintaining good water quality and keeping vegetation under control will help ensure good fishing.

For additional information and technical help, contact a fisheries biologist with the Missouri Department of Conservation. Your local MU Extension center can also provide information and help with managing your pond for fishing, aquaculture, irrigation or recreational uses.
