The financial sustainability of aquaculture depends on two important aspects, production and profitability. The diminishing profit margin of farmers in agriculture and the reducing per capita land due to the burgeoning population is pivotal to trigger, a resource-specific and species-specific approach to explore the full potential of aquaculture systems. Different models to explore the production potentials of different culture systems, techniques, and species under culture, are essentially required to ensure production and profit efficiency leading to income and cost-effectiveness in aqua farming. The integration of different techniques or resources or trophic levels and intensive practices may be the key future efforts to ensure sustainability such integration has been tested by Regional Research and Training Centre (RRTC) Motipur of ICAR- Central Institute of Fisheries Education (CIFE) Mumbai and named as 3 phase 3 cycle (3P3C) Model. This model for mixed farming of fish is with 3 different phases leading 3 cycles of production in a year. In the first phase, nursery rearing is done in nursery ponds. Then, it is followed by the phase-out culture of seed to grow out stocking under intensive farming of the biofloc based culture. Finally grow out farming of carps and catfish together in mix farming in pond is done. It has led three to five times more production per year from the same area of land and water in an efficient manner. The model is useful for both the condition of flood and drought and even for overwintering of the low temperature.
