Role of phytoplankton

• Major food for phytoplankton.
• The base of the food web in the fish pond.
• Make water turbid and prevent the growth of undesirable aquatic weeds through shading.
• A major source of dissolved oxygen in water.

Role of zooplankton

• Major food for zooplankton feeder fish.
• The major food item for larvae or juveniles of most fish species.
