凡纳滨对虾与全雄性罗非鱼混养试验
Pacific white shrimp (Litopenaeus vannamei) and all-male tilapia (Oreochromis niloticus) polyculture
摘要
Abstract
In this study, using specifically designed cages, the pacific white shrimp (Litopenaeus vannamei) and all-male tilapia (Oreochromis niioticus) polyculture were studied to avoid competitive feeding in order to prevent disease, increase production yield, and improve benefits. [Method]According to the differences in biological characteristics of pacific white shrimp and all-male tilapia and their baits' characters, tilapia bait feeding was temporally controlled by opening and closing of the water passages to avoid tilapia's excessive, consumption of pacific white shrimp. The study was conducted in two 6.67 ha ponds by mixing 67.5x104 post-larvae/ha pacific shrimps and 6.0xl07 fingerlings/ha all-male tilapias. The yield was determined by analyzing the culturing effects after 118 days. [ Result ] During the polyculturing process, no diseases were detected for pacific white shrimp and all-male tilapia under relative stable water quality. After 118 days, the yield of shrimp and tilapia averaged 6212.1 and 3522.7 kg/ha, respectively; the comprehensive ratio of input to output was 1:1.52 and the average benefit was 75985 Yuan/ha. [Conclusion]It is feasible to apply mixed culturing of pacific white shrimp and all-male tilapia in the same pond with the appropriate confinement methed.关键词
