The study was carried out in a fish hatchery farm in North 24 PGs districts of West Bengal State in India. Structured questionnaires were used to find out different wings and arena of the enterprises. The hatcheries were building up in 1987 taking loan from the bank with an inspiration from the ancestors.
Infrastructures
The farm had four numbers of Hatcheries, eight number of Pump (5 HP), four Motors of Horse Power, four numbers of water tank and six numbers of Nets for covering the hatcheries as its infrastructural assets. 6 labours needed as human resources for 6 month.
Key Activities by steps:
Step 1: Buying of brood fish (male & female) (Jan,Feb,March)
Step 2: Feeding of fish (Ground Nut Cake,Rice,Mahua Cake,Boiled Pea,Soyabean Dust, lentil,Cerelac)
Step 3: Application of lime for hardiness of fish and Methylene Blue against diseases.
Step 4:Catching of male and female fish by netting during April.
Step 5: Placing them in breeding hapa for 4 hours
After 4 hours inducing hormones are injected to male and female fish as per the doses in Table-1. Thereafter 5-7 hours female fish lay eggs. The fishes are then taken out from the breeding hapa. “Haritoki Cosh” has been added for hardening the egg sponge. Subsequently after 24 hours eggs are hatched. In about 72 hours of hatching seeds are ready for marketing.

Marketing Channel
Marketing channels has also been studied for proper understanding of economics and the after process. It has been identified by several questionnaires that the enterprise can directly sell the seeds to the fish cultivar or can sell in local market for onward selling to the fish farms. Generally the dealers come to them and according to their need they supply the spawns. A numbers of marketing channels involves in these types of hatcheries (Chaudharya et al., 2021)
