What is aquaculture? • The cultural production of plants & animals in water. • The culture and harvest of aquatic animals & plants usually for food & fiber. • “Water farming”
History of Aquaculture • 2000 B.C. • Aquaculture started in China with common carp • 1700 • Japanese practiced mariculture • Aquaculture in saltwater • Middle Ages – Europe • Fish grown in moats around castles • Main use was to store fish caught in the wild until the were needed for food
U.S. Aquaculture • National Aquaculture Act of 1980 • Established aquaculture as a national priority • Stated that various government agencies should work together in planning aquaculture development in the nation.
Why has aquaculture grown in the last 50 years? • Production increases in catfish, trout and salmon industries. • Aqua farmers have learned to make their operations more profitable by vertically integrating the industry. • Increase in consumption in fish and seafood
Advantages of Aquaculture • Provides a quality product on a year-round basis • Insures a larger supply of the desired or demanded aqua crops • Insures availability • Can control environment of production • Eliminates possibilities of contamination of water fish are grown in • Helps provide essential nutrients in the human diet • Fish are a good source of protein and other nutrients
Disadvantages of Aquaculture • Technology not yet available for the production of some crops • For crops to be produced, the farmer must know how to produce the crop. Right now there is not a lot of information about how to produce certain crops. • Lack of knowledge about aquaculture • Competition from wild fish and seafood
Importance of Aquaculture • Source of Food • Supplies a quality source of nutrition for a growing population • Provides valuable non-food products • Fine leather – eel skins, alligator hides. • Cultured pearls from oysters • Shells & skeleton parts for home & business decoration • Frog & other aquatic animals for educational purposes – dissection • Less valuable shells are used in paving roads & ornamental landscaping
Contributes to human heath research • Dieting supplements • Medical research • Creates demand for grain crops • Used in feed rations for fish • Creates jobs & economic activity • Jobs created in producing & marketing aqua crops • Provides recreation • Sport fishermen are using “fee-lakes” stocked with cultured fish • Improves scenic beauty • Aquascaping • Using aquaculture to add aesthetic beauty to an area
Three main types of Aquaculture • Warm water aquaculture • Commercial raising of stock that thrives in warm, often turbid fresh water with temperatures between 70-90 degrees F • Cold water aquaculture • Commercial production of stock that thrives in cool, clear fresh water with temperatures of 65 degrees F and under. • Salmon & trout • Mariculture (marine culture) • Crop thrives in salt water of various temperatures • Shrimp, oysters, and seaweed cultures.
