Aquatic Farming Methods: Hatchery, Nutrition and Feed Management

Fish farming or pisciculture is the major type of aquaculture, while other techniques may fall under mariculture. Aquaculture and fishery management entails raising fish profitably in tanks or enclosures, regularly for food. A competence that fish wild for recreational fishing or to increase a species' natural numbers is commonly referred to as a fish hatchery. The fish species used in fish farming are carp, salmon, tilapia, catfish across the world. Species that are estimated 230 species of fin fish, molluscs, crustaceans, aquatic plants, turtles, frogs, etc. are cultured. Culture systems like water-based systems, such as cages and pens, bottom, pole, rack, raft long-line systems for inshore and off-shore; land systems such as rain-fed ponds; irrigated or flow-through systems, tanks and raceways; land and water based systems, sea ranching; recycling such as high control enclosed systems, more open pond-based recirculation systems; integrated farming systems, such as integrated aquaculture, livestock-aquaculture.
