Introduction To Aquaculture

Aquaculture: It can be defined as a sustainable practice of fish harvesting that strives to keep aquatic biodiversity and ecosystems intact. Aquaculture provides an alternative to wild fish sanctuaries throughout the world.
The aquaculture is understood to mean the farming of aquatic organisms including fish, crustaceans, molluscs and aquatic plants. It also known as aqua farming or culture fisheries. It involves cultivating of Inland water and marine water organisms under controlled conditions, and it can be contrasted with commercial fishing, which is the harvesting of wild fish. The culture are regarded as to shellfish and finfish fisheries is analogous to the relation of agriculture to gathering and hunting. Mariculture refers to aquaculture practiced in marine environments and in underwater habitats.

The broad views of aquacultures include fish farming, shrimp farming, oyster farming, mariculture, algaculture (such as seaweed farming), and the cultivation of ornamental fish. Particular methods include aquaponics and integrated multi-trophic aquaculture, both of which integrated fish farming and plant farming.

The aim of aquaculture is to produce a blue revolution. It is the culture of fisheries. It is the culture of fishes and other aquatic organisms using advanced technologies. It is an industry or occupation. The products of aqua-culture is called aqua food which are consume by human.

It is a branch of fisheries and fisheries is an occupation or industry of catching and culturing fishes and other aquatic organisms.

Organizations related to Aquaculture and Fisheries

The Indian Government established a number of institutes for education and research in Aqua-culture. They provide education for students and produce graduates and postgraduates on Fisheries.

The Research institutes produce scientists and the scientists design new technologies. The new technologies are implemented by the farmers. The institutes are functioning under five Government organizations. They are
