This study was designed to determine the interrelationship between physico-chemical parameters and plankton community in three different aquaculture systems (wishpond, wishpond aquaponics traditional fish pond). The water quality parameters, dissolve oxygen (DO), temperature, pH, ammonia, alkalinity transparency were monitored found within recommended range. Different phytoplankton of four (4) ...
