Aquaculture produces huge quantity of waste water which can be efficiently recycled for plant cultivation and offer an eco-friendly way for increasing economical and sustainable farming. In this study we investigated growth performance of Tilapia fish (Oreochromis niloticus L.) and fenugreek (Trigonella foenum-griaecum) using recycled fish tank effluent. In 30 days experimental period, fishes were fed with probiotic Lactobacillus delbrueckii LABT1 supplemented diet and compared with fish grown without probiotic diet and fish reared in aquaculture without recycling of fish effluent was taken as control. Fish cultivated water from each tank were recycled through fenugreek cultivation tray and optimum water quality parameters were maintained throughout the experimental period. Due to the effective utilization of waste water for fish and plant production, significant increased fish length and weight gain were observed using probiotic supplemented diet. Further it showed increased specific growth rate and survival of 100%. Also the fenugreek grown in fish effluent showed significantly higher plant length. Results from this study confirm that fish effluent can be effectively recycled and reused for Tilapia and fenugreek cultivation.
