Finfish Breeding and Hatchery Management (2+1)

Unit 4 - Different types of fish hatcheries

4.2.1. Infrastructure of eco – hatchery complex for carp seed production (Chinese type)

• For commercial success of fish hatcheries, infrastructural facilities are prerequisites.
• Due to lack of infrastructural facilities, realization of fish seed in nursery/rearing ponds is poor in many states.
• Modern carp eco-hatchery is the most appropriate system to produce seed of Indian major carps and exotic carps.
• It is an integrated one, with infrastructure for broodfish care, breeding tank, hatching/incubation tank, spawn and fry rearing, packing and marketing of seed, water supply system and buildings.
