Abstract— Artificial feeding of fish enriches water mass with particulate organic matter, which serves as a feed for zooplankton. Phytoplankton was present in the pond in small amounts with the predominance of green, euglena, and yellow-green algae. Digging the ground, fish mix silt and waste products. Bacteria living on the bottom and in water release gas bubbles, which bring into the surface layers bacteria and fine detritus particles serving there as a feed for zooplankton.
