The modern hatchery manager's goal is to produce large numbers of uniform, robust, day-old chicks. Robustness is a health criterion, originating in the embryonic life stage of the chicken – and correlating directly with the performance and resistance of individual chicks under differing farm conditions.

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 ...
Nowadays hatcheries have expanded with more machines than before. The hatchery is not a factory, it is a place for oysters to grow and be harvested and then transported. The oyster larva has a soft body. It begins to grow an outer skin and finds a solid mass to settle on.

A hatchery is a facility where eggs are hatched under artificial conditions, especially those of fish, poultry or even turtles. [ 1 ] [ 2 ] [ 3 ] It may be used for ex situ conservation purposes, i.e. to breed rare or endangered species under controlled conditions; alternatively, it may be for economic reasons (i.e. to enhance food supplies or ...
Fish used in this system include catla and silver carp (surface feeders), rohu (a column feeder), and mrigal and common carp (bottom feeders). Other fish also feed on the excreta of the common carp, and this helps contribute to the efficiency of the system which in optimal conditions produces 3000–6000 kg of fish per hectare per year.
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.
It can be used to predict events in the fishery if certain factors change. See population dynamics. Socioeconomics – A word used to identify the importance of factors other than biology in fishery management decisions. For example, if management results in more fishing income, it is important to know how the income is distributed between ...
