Aquaculture is the farming of aquatic organisms — fish, molluscs, crustaceans and aquatic plants — classified by water source into freshwater aquaculture (inland rivers, lakes, ponds and reservoirs, salinity below 5 ppt), brackish water aquaculture (estuaries, backwaters and coastal lagoons, salinity 0.5–30 ppt) and marine water aquaculture/mariculture (India's roughly 5,600 km coastline, salinity 30–35 ppt), with a further metahaline category (36–40 ppt) exemplified by the brine shrimp Artemia salina. Fish culture (pisciculture) is its largest component: a good cultivable fish must grow fast, accept supplementary feed, resist disease, coexist in polyculture and convert feed efficiently, which is why major carps (Catla, Labeo, Cirrhinus) dominate Indian practice. Managing a fish farm moves stock through a chain of specialised ponds — breeding ponds (using natural bundh breeding or induced breeding via artificial fertilization or hypophysation), hatching pits, nursery ponds, rearing ponds and stocking ponds — bef …
