Experiments were conducted from 1992 to 1999 to determine if aquaculture water and effluents can be used to replace expensive irrigation water and fertilizer for vegetable and forage crops. In 1992 and 1993, effluents were applied to bell peppers. (Capsicum annuum L.). h11994 effluents were applied to leafy vegetable Pai tsai (Brassica rapa L. Chinensis). Fronl 1997 to 1999 the benefits of utilizing aquaculture effluents was evaluated for guineagrass (Panicum maximum Jacq.) hay production. Trials for two seasons demonstrated the positive effects of using aquaculture effluents on vegetables and forage crops. Effluents increased vegetable marketable Yield, dry matter and nutrient value of guineagrass. Studies indicated that recycled aquaculture water and effluents are potential sources of irrigation water and feliilizer.
