A fish hatchery is a place for artificial breeding, hatching, and rearing through the early life stages of animals—finfish and shellfish in particular. [1] Hatcheries produce larval and juvenile fish , shellfish , and crustaceans , primarily to support the aquaculture industry where they are transferred to on-growing systems, such as fish ...
The National Fish Hatchery System (NFHS) was established by the U.S. Congress in 1871 through the creation of a U.S. Commissioner for Fish and Fisheries. [1] This system of fish hatcheries is now administered by the Fisheries Program of the U.S. Fish and Wildlife Service (Service), an agency within the United States Department of the Interior.
Other hatcheries release the juvenile fish into a river, lake or the ocean to support commercial, tribal, or recreational fishing or to supplement the natural numbers of threatened or endangered species, a practice known as fish stocking. Researchers have raised concerns about hatchery fish potentially breeding with wild fish.
This List of National Fish Hatcheries in the United States includes the 70 National Fish Hatcheries, seven Fish Technology Centers and nine Fish Health Centers that are administered as components of the National Fish Hatchery System by the U.S. Fish and Wildlife Service.
For trout, stocking rates of 30 to 50 kg/m 3 are normal at the end of a rearing cycle, while for marine species, such as sea bass and sea bream, the achievable load is lower, between 15 and 20 kg/m 3. The total volume required for a raceway is calculated by dividing the total amount of fish in kg by the desired stocking rate in kg per m 3. [17]
The U.S. government will invest $240 million in salmon and steelhead hatcheries in the Pacific Northwest to boost declining fish populations and support the treaty-protected fishing rights of ...
Added to the hatchery in 1995, this program works toward the restoration of freshwater mussel populations.
