The number of fish depends on the size of the pond. In general, a half-acre pond would need a total of approximately 390 to 400 fish, while a one-acre pond would require double that number, or about 780 fish. If you stock the suggested fish, the ratio for a small pond would be 240 bluegill, 120 yellow perch and 30 largemouth bass.
Over the years, it has been determined that a quarter-acre pond is the minimum size required to support a consistently healthy supply of fish for recreational purposes. Before stocking, you should note any “wild fish” that may exist. They can be deposited in a new or existing pond in several ways. Sometimes fish eggs or fry are deposited into a pond by migrating waterfowl, or that might be introduced into the water on aquatic plants. Occasionally, runoff or flooding from other waterways will deposit unwanted fish in a recreational pond. It is considered almost inevitable that some unplanned fish will find their way into your pond. What you will want to ensure is that they do not reproduce in large numbers and destroy the balance you have worked hard to achieve.
By selecting fish of similar size when you initially stock your pond, you will help your fish population mature together. Although different fish grow at variable rates and have differing lifespans, achieving a desirable balance of fish to catch over a span of years is the goal. By monitoring the number s of fish caught each season, you should be able to anticipate and plan for your future restocking needs.
Where to Obtain Stocking Fish
No matter what fish you choose to stock your pond, purchase your fish only from an authorized, reputable fish supplier who is in full compliance with all federal, state, and local regulations. You will want to pay particular attention to your local laws if you consider buying fish from sources outside your home state.
Stocking healthy, disease-free fish from a reputable fish supplier will help reduce the chances of outbreaks and subsequent fish kills.
