Fertilizer stimulates growth of microscopic plants, called phytoplankton. Phytoplankton form the base of the food chain and are eaten by small animal organisms, which serve as food for bream, which in turn are eaten by bass. Phytoplankton make the water turn green, or "bloom," which also shades the bottom and discourages growth of troublesome aquatic weeds.

Proper fertilization will significantly increase the total weight of fish produced in a pond. If only a few people will fish a larger pond, it does not necessarily need fertilization to have good fishing. A heavily fished pond, on the other hand, should be properly fertilized to produce the best fishing.

Many Mississippi fish ponds do not develop a satisfactory phytoplankton "bloom" when fertilized at recommended rates because of low soil pH and water alkalinity. Liming can increase fish production in ponds with acid bottom mud and soft water by altering the soil pH and alkalinity of the water.
