The ultimate fate of many farm ponds in Mississippi is an unbalanced fish population that is undesirable to fishermen, and, therefore, has little recreational fishing value. Once a fish population reaches such a condition, the best alternative is usually to eliminate the resident fish completely and to restock with a desirable combination of fish at recommended rates. Consult a fisheries biologist to determine the condition of your pond and the possible need for a complete fish population renovation or a partial fish kill.

Antimycin and rotenone are two pesticides registered by the Environmental Protection Agency for eradication of fish. Only rotenone is economically feasible for eradicating complete fish populations and is the more commonly used compound. Antimycin can be used to kill scaled fish selectively from catfish ponds, but treatment is usually expensive.
