Abstract
Conservation hatcheries are like luxury fish hotels that raise threatened and endangered fish that are nearing extinction in the wild. Raising fish in the controlled environment of the conservation hatchery usually takes away the issues that caused the population to dwindle in the first place. However, there is one problem: the fish get used to the conservation hatchery and become wimpy, meaning they become domesticated and do not do as well as wild fish in if they are returned to the natural environment. Managing the genes of hatchery fish is one way to block domestication and raise fish that are as close as possible to wild fish. In the San Francisco Estuary watershed, there are conservation hatcheries for the endangered delta smelt and winter-run Chinook salmon. Read on to learn about how these conservation hatcheries help hatchery fish be as tough as possible and survive in the wild.

The United States has laws in place to make sure that threatened and endangered species are protected and that there is a plan with specific actions to help the populations improve
Summary
When a species is threatened or endangered, it is at risk of becoming extinct. One possible action for fish species that are at risk of extinction is to raise them in a conservation hatchery, or luxury fish hotel, and later release them into the wild. The goal of production hatcheries is to make as many fish as possible for food or fishing. The goal of a conservation hatchery is to raise fish that are as similar as possible to wild fish of the same species, but in a controlled environment. This is done so that hatchery fish can survive and mate when they are released into the wild. Your grandparents are one, your parents are a second, and you are a third generation
