Classification of Aquatic Animals:

There are two types of culture Monoculture and Polyculture. Monoculture is the culture of specific species at a time.The advantage of this method of culture is that it assists the farmer to make the feed that will meet the requirement of a specific fish, especially in the intensive culture system. Polyculture is the practice of culture more than one species of aquatic organism in the same pond. Raising of different combination of fish in single pond is the motivational principle. They are also classified according to their Size and Feed.

Fish Hatchery:

Artificial breeding , rearing and hatching at an early stage,are the common fish hatching procedures followed for fin fish and shellfish in particular. The hatchery supports the other aquaculture industry by supplying early stages of cultured species like larval, juvenile fish and shell fish. They are transferred to on-growing systems, such as fish farms, to reach the harvest size. The production type, issue of Fish Hatchery, Hatchery Design are included in Fish Hatchery.

Fisheries Management:

Fisheries management is the activity of protecting fishery resources. Precautionary principle is the fishery Manager's Guidebook issued in 2009 by the FAO (Food and Agriculture Organization) of the United Nations, advises that the precautionary approach or certain principle are should be applied. Study and analysis of emerging and specialized area of marine food and aquaculture is fisheries law.

Industrial Aquaculture:

Industry aquaculture activity concerned with extraction, culturing, processing, preserving, storing, transporting, marketing or selling fish or fish products. Catching of fish, culturing the fish, selling the fish and fish related products in a good quality in market are the commercial sector practices.Traditional sector include commercial sector but it is in very small scale, the fishing is in a traditional way such as rod and tackle, arrows and harpoons, throw nets and drag nets, etc. Various organizations provide Fishing books, magazines, design and building of boats with provision of accommodation, guide for fishing adventure, manufacture and retail of tackle and apparel. The ocean covers 71% of the earth's surface and 80% of the value of exploited marine resources are attributed to the fishing industry.

Fishery is the kind of industry which includes catching and selling of fishes for the purpose of food, medicine and research. Other than marine water fisheries there are fresh water fisheries as well. There are two types of waters, namely, the fresh and the brackish. The fresh water sources are irrigation canals, reservoirs, lakes, tanks, pondsThe estuaries, lagoons and mangrove swamps constitute the brackish type of water.

Coastal Studies:

Wave action hit the shoreline constantly with different strengths which shape the coastal lines resulting into various land levels. The sand dunes are made by atmospheric wind which blow in beach sand. Sedimentation in rocks, plants, animal and marine life is affected by warm weather condition. The salt is taken from the sea by wind and formation of salt crystals in the small pores in rocks leads to various rock texture. Due to the climatic change the sea levels rise and fall.
