Yield of tomato irrigated with recirculating aquacultural water
1993
Aquacultural water, which rapidly accumulates organic materials that inhibit fish growth, has considerable potential for hydroponic cultivation of vegetable plants. By recirculating aquacultural water through sand biofilters, it is possible to integrate the two systems whereby both benefit: the vegetables are provided with nutrient-laden water and they control ammonia concentrations in the fish medium. Hybrid tilapia fish [Oreochromis mossambicus (Peters) × O. niloticus (L.)] and tomato (Lycopersicon esculentum Mill.) production were linked in a closed recirculating water system in a polyethylene greenhouse to determine the effect of tank-to-biofilter ratio on tomato yield. The fish were raised in tanks and fed a 32% protein feed [...]
