Ponds should be limed before fertilizer is applied. By increasing the production of phytoplankton (the base of the food web), production of other pond organisms also increases. A fertilization schedule can dramatically improve fish production in ponds by up to 300 percent, and fertilization can also decrease aquatic weed problems by shading the pond bottom, so that aquatic weeds do not have an opportunity to grow. With a fertilized pond, you have more fish and your fish will have more to eat; in return you have bigger fish to catch.

The best fishery results have been achieved with three-day fertilization giving a total growth of the fish of 2 730 kg/ha and a food coefficient of 2.8. Also ponds in which the fish are fed or which receive runoff water that is rich in nutrients generally do not require fertilization. Fish reproductive organs include testes and ovaries.In most species, gonads are paired organs of similar size, which can be partially or totally fused.
