Growth and Production Occurance of Monosex Tilapia (O. niloticus) in Tank Based System: Sustainable Development for Rural People of West Bengal, India

Monosex tilapia, the world’s most culturally diverse fish species, has reached new heights of productivity in recent years. Because of the high demand and value of this species on the local and international market, it plays an important role in the fish farming industry. The limits of pond culture are reduced by using a tank-based culture method, which may generate extremely high yields year-round on tiny plots of land. Male tilapia can grow to marketable size in tanks with a high fish density, which disrupts breeding behaviour. From August 2016 to March 2017, a research was done at Kelomal village in the Purba Medinipur area of West Bengal to evaluate growth, output, and profit analyses. According to the findings, if a person invests Rs.2879 in tank farming for three months (length, breadth, and depth ratio of 30:3:1), the net profit after all expenses is Rs.3025. As a result, determining how profitable it is is simple (nearly 50 percent). Because hybrid monosex tilapia (Oreochromis niloticus) are rapid developing and have an omnivorous feeding habit, they reached market size of > 180g after each 120-day production cycle. For the three production cycles, the feed conversion ratio (FCR) ranged from 2.80 to 2.81. By analysing the growth patterns of monosex tilapia under tank culture systems, the study’s main goals were to establish a sustainable rural livelihoods aquaculture technology for the production of a key animal protein supply. Commercial monosex tilapia farming can play an essential role in ensuring people’s long-term growth and meeting their protein and nutritional needs in this way.
