A fish hatchery is a facility designed to breed and raise fish, particularly for restocking purposes or commercial aquaculture. In these facilities, eggs are fertilized and incubated in controlled environments to ensure optimal growth and survival rates. The hatchery often focuses on species like trout, salmon, or catfish, depending on local demand and ecological needs. Once the fish reach a certain size, they are released into natural bodies of water or sold to fish farms. Hatcheries play a crucial role in supporting fisheries, enhancing biodiversity, and providing a sustainable source of fish for both recreational and commercial fishing.
