A fish hatchery is a facility designed to breed and raise fish, particularly for the purpose of stocking lakes, rivers, and other bodies of water. These facilities help support fish populations, enhance recreational fishing, and restore endangered species. Hatcheries typically focus on species like trout, salmon, and catfish, providing controlled environments for their growth. In a hatchery, fish eggs are collected, fertilized, and placed in tanks or ponds where they can develop. Once the fish reach a certain size, they are released into the wild. This process helps ensure that fish populations remain healthy and sustainable for future generations.
