Hatcheries are facilities where eggs are incubated and hatched, primarily for fish, poultry, and other animals. They provide controlled environments that optimize temperature, humidity, and ventilation to ensure the successful development of embryos. Hatcheries play a crucial role in aquaculture and agriculture by supplying young animals for farming, restocking wild populations, and supporting food production. In addition to fish and poultry, hatcheries can also be involved in the breeding of reptiles and amphibians. They often use advanced techniques, such as artificial incubation and selective breeding, to enhance the health and growth rates of the hatchlings. This helps meet the demands of both commercial markets and conservation efforts.
