There are numerous benefits of fish hatcheries that have led to them being so popular. To begin with, as a result of the increasing demand for food, the oceans and seas have become heavily farmed. Hatcheries allow for the replenishment of fish in these waters, at a rate much faster than nature would allow. This allows consumers to gain access to a guaranteed supply of seafood, as well as ensuring farmers will continue to generate revenue from farming the animals. Also, hatcheries can provide food sources to carnivorous fish, enabling their continued supply. Recent years have seen the rise in popularity of the seafood diet due to its plentiful health benefits reported by many scientific studies. Today, protein and Omega-3 has become a focus of many people’s diets for muscle growth, memory function, eye health, lower risk of heart disease, and more. Seafood is naturally high in these substances, which are not only beneficial to the general population but can also impact on communities...
While there are numerous benefits to fish hatcheries, it can be argued that the drawbacks outweigh these advantages. Firstly, fish hatcheries have been identified as a source of pollution to aquatic environments due to some of its practices. Also, because these fish are farmed in very dense conditions, their waste products become more concentrated, which can favor the development of microorganisms that can be directly harmful to the fish. Also, while the perception of farmed fish is that they are cleaner than wild fish, this is not the case. Studies have shown that farmed fish have higher levels of toxic substances such as antibiotics, organic pollutants, and pesticides than are found in wild fish. Consumers eating farmed fish are, therefore, at risk of the adverse health effects associated with consuming these contaminants. Pregnant and nursing women are of particular risk to these detrimental health effects. Studies have also shown that fish from hatcheries have lower reproductive...

A fish hatchery is a place for artificial breeding, hatching, and rearing through the early life stages of animals—finfish and shellfish in particular. 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.
For over 145 years, the National Fish Hatchery System (NFHS) has worked collaboratively with tribes, states, landowners, partners and stakeholders to promote and maintain healthy, self-sustaining populations of fish and other aquatic species. The NFHS consists of (70) National Fish Hatcheries, one historic National Fish Hatchery, nine Fish Health Centers, seven Fish Technology Centers, and the Aquatic Animal Drug Approval Partnership Program. The unparalleled conservation efforts of this system not only enhance fishes and their habitats, but also angling opportunities for our Nations 58 million recreational anglers and associated economies.
National Fish Hatchery System propagation addresses top priorities such as enhancement of recreational fishing and public use of aquatic resources, recovery of federally-listed threatened or endangered species, restoration of imperiled species, and fulfillment of tribal partnerships and trust responsibilities. Hatcheries work closely with Federal agency partners, like the US Army Corps of Engineers, to mitigate impacts of Federal water projects via reimbursable service agreements. In order to maintain excellence in aquatic conservation to ensure healthy fisheries, Fish and Wildlife Service professionals closely monitor the health, status, and trends of aquatic populations; measure the quantity and quality of important aquatic habitat to support strong fisheries; and limit the outbreak and spread of invasive species and disease-causing pathogens. In Fiscal Year 2018, (70) NFHS facilities, (1) Historical NFH, and (1) Fish and Wildlife Conservation Offices distributed (released and transferred) 230,583,112 juveniles, adults, and eggs of (6) different taxonomic groups, encompassing (94) different species into (46) states.
