Finfish Breeding and Hatchery Management (2+1)

Fish nursery pond

● In India, carp culture is carried out in three phases (three-tier system) comprising nursery phase (rearing three-day-old spawn to fry), rearing phase (rearing fry to fingerling stage) and grow out phase (rearing fingerlings to adult stage).
● Of  the three  phases, the nursery  rearing is crucial and needs greatest attention of fish hatchery managers.
● The preparation of nursery pond before releasing the stocking material is an important step for successful rearing of carp spawn to fingerlings.
● The occurrence of large scale mortality of stocked spawn in unprepared nurseries is very common through out the country.
● Fish nursery is a small pond of  0.01 – 0.1 ha, with a depth of  0.5 – 1.2 m, rectangular and drainable.
● It consists of pre-stocking, stocking and post-stocking management.
