Production of Big sized fish is a major concern of the Fisheries Department, Govt. of West Bengal. “Mache Bhate Bangali” always searches for big fish (e.g. Paka Rui / Catla) on any occasion or in daily life. The Fisheries Department, Government of West Bengal has taken initiatives to bring all water bodies (Ponds / Beel / baors etc.) under scientific pisciculture for better productivity in the inland sector. The State of West Bengal is enriched with a large number of big-sized & highly productive water bodies which have immense scope towards the production of Big Sized Fishes to narrow down the gap between the demand for big fish and its supply.

Keeping these in mind, the scheme for “Production of Big Size Fish (IMC) in Big Water Bodies” has been formulated with the following objectives:

• To produce Big Sized Fishes with the application of nutritionally balanced floating pelleted feed and proper management of water bodies
• To involve the Fishermen's Co-operative Societies, Self-help Groups, and Fish Production Groups to uplift their socio-economic status since the big water bodies are mostly been managed by them.
• To meet up the demand for Big Sized fish in the locality.
• To create awareness among the fisher flock and effectively demonstrate improved technology towards the scientific culture of big-sized fishes to them.

Assistance under this scheme has been provided in terms of Carp (IMC) Fish seed (250 g) @ 7500 no/ha, Processed good quality floating pelleted fish feed; (Size - 1.5 - 2 mm dia. Animal protein - 28-32%, fat -4 1%) to the beneficiaries as Government Contribution. Beneficiary contributions are Pond Preparation, Lime (Calcium Oxide) @ 500 kg/ha/year, Inorganic fertiliser SSP @ 300 kg/ha/year, Prophylactics & Medicine, Labour Charges with periodical netting and harvesting expenses lump sum amount.
