For decades hatcheries have provided important mitigation for the loss of naturally spawned salmon and steelhead while providing for fishing opportunity. A decision on the size of the hatchery is a fundamental pre-requisite before starting the search for suitable sites, or before starting the technical design or the financial plan. Hatchery-reared fish are used to establish new populations, enhance existing populations, support research efforts, and maintain fisheries in small urban reservoirs where natural production will not meet anglers' needs. Important problems in hatcheries and early rearing systems are caused by some of the following pathogens: Protozoan ciliates like Ichthyophthirius multifilis (white spot disease . 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. Hatcheries and pre-ongrowing units must rise to the challenge of producing and achieving consistently high standards so European seabass and gilthead seabream are able to excel from hatching to harvesting. The role of the hatchery is very different from farm (Numbers of appropriate size). With that in mind, Picture yourself performing scientific, technical, and related maintenance duties at the Tucannon Hatchery, rearing anadromous (fish born in freshwater who spend most of their lives in saltwater and return to freshwater to spawn) and non-anadromous species of fish..
