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

Monosex tilapia is the maximum diversified culturally fish species within the world, has got new heights of production in current times. It takes a vital role in the fish farming business for great demand and value of this species in the local and international market. Tank based culture system reduces the limitations of pond culture and it can produce very high yields, year round, on small parcels of land. Tanks with a high fish density disrupt breeding behaviour and allow male tilapia to grow to marketable size. To evaluate the growth, production and profit analysis the study was conducted at Kelomal village of Purba Medinipur district of West Bengal from August, 2016 to March, 2017 following standard protocol. The results showed that if a person invests Rs.2879 in tank farming(length, width, and depth ratio is 30:3:1) for three months , the net profit after all expenses is Rs.3025. As a result, it is simple to determine how profitable it is (nearly 50 percent). Hybrid monosex tilapia (Oreochromis niloticus) was used in this study because fast growing and with their omnivorous feeding habit, attained market size of > 180g after each production cycle lasting 120 days. The feed conversion ratio (FCR) varied from 2.80-2.81 for the three production cycles. The main targets of this study were to establish on a sustainable rural livelihoods aquaculture method for the production of a major animal protein source by comparing the growth pattern of monosex tilapia under tank culture systems. In this manner, commercial monosex tilapia farming can assume an important role for making the people sustainable development and satisfying the protein and nutritional demand.
