Effects of Chinese Waterchestnut in Floating Rafts on Production of Channel Catfish in Plastic Pools

Chinese waterchestnut was grown in rafts floating on catfish pools to determine effects on production of channel catfish fed daily. This plant may remove nutrients from the water and increase catfish production by improving water quality and, also, produce a second crop, the edible corm ofthe plant. Catfish were stocked in March, Chinese waterchestnuts were planted in April, and both were harvested in October. Survival and production of fish were 56% and 1230 kg/ha, 86% and 1871 kg/ha, and 87% and 1952 kg/ha in pools with fish only, fish and raft, and fish and raft with waterchestnut,...
