Genetic modification is conducted in some hatcheries to improve the quality and yield of farmed species. Supply can be further guaranteed by sourcing from hatcheries in the opposite hemisphere i.e. Broodstock conditioning can extend the natural spawning season and thus the supply of juveniles to farms. Hatchery production confers three main benefits to the industry:Ĭonsistent supply of fish from aquaculture facilities is an important market requirement. Hatcheries produce larval and juvenile fish and shellfish for transferral to aquaculture facilities where they are ‘on-grown’ to reach harvest size. Purpose Assynt Salmon Hatchery, near Inchnadamph in the Scottish Highlands. Fish and Wildlife Service have established a National Fish Hatchery System to support the conservation of native fish species. Culture of finfish larvae has been utilised extensively in the United States in stock enhancement efforts to replenish natural populations. There is much interest in supplementing exploited stocks of fish by releasing juveniles that may be wild caught and reared in nurseries before transplanting, or produced solely within a hatchery. Additional hatchery production for small-scale domestic uses, which is particularly prevalent in South-East Asia or for conservation programmes, has also yet to be quantified. The value of global aquaculture farming is estimated to be US$98.4 billion in 2008 with China significantly dominating the market however, the value of aquaculture hatchery and nursery production has yet to be estimated. Some species that are commonly raised in hatcheries include Pacific oysters, shrimp, Indian prawns, salmon, tilapia and scallops. 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 farms, to reach harvest size. Aquaculture facility Tanks in a shrimp hatchery.Ī fish hatchery is a place for artificial breeding, hatching, and rearing through the early life stages of animals-finfish and shellfish in particular.
