FOOD HABIT COMPARISON OF TWO POPULATIONS OF BLUE TILAPIA, OREOCHROMIS AUREUS (STEINDACHNER), IN NORTH CENTRAL FLORIDA

Food habits of two populations of blue tilapia, Oreochromis aureus (Steindachner), in north central Florida were compared for type, amount, and energy of foods consumed. Blue tilapia in Lake Alice consumed mostly diatoms (probably detrital in nature), whereas blue tilapia in Lake George ingested mos...

description Food habits of two populations of blue tilapia, Oreochromis aureus (Steindachner), in north central Florida were compared for type, amount, and energy of foods consumed. Blue tilapia in Lake Alice consumed mostly diatoms (probably detrital in nature), whereas blue tilapia in Lake George ingested mostly epiphytic green algae and diatoms. Stomach fullness was highest in fall samples and lowest during spawning (March and April) months in both lakes. Total energy values (kilocalories/gram dry weight) were significantly (P̱
