The aquaculture activity can be simply classified into fed and non-fed culture based on its feed supplementation. In non-fed culture systems, fish is completely relying on natural food present in the captive conditions to fulfill their nutritional requirement and there will not be any supplementation of pellet feed. Nowadays, most of fish farmers are focusing on mariculture and they are growing mussels, seaweed, oysters and clams, etc., different part of world. Present production of the unfed species aquaculture production is 54.4 mmt, including seaweeds, which comprises of filter-feeding finfish (8.8 mmt), and aquatic invertebrates (15.6 mmt) and aquatic plants (30 mmt). The share of un-fed species to the total aquaculture production is 49.5% (FAO, 2018). Effective implementation of non-fed aquaculture activity at coastal sites would have various socio-economic benefits to the fish coastal farmers. The major challenge associated with non-fed aquaculture is the availability of seed. There are no well-established commercial hatcheries to supply the bivalve seeds; therefore, the farmers are completely depending on natural seeds for their stocking. In this context, it is wise to implement and promote the low-investment oriented eco-friendly sustainable non fed aquaculture technologies among the coastal areas to uplift the socially and economically backward stakeholders of this sector.
