Answer 1

The two ways of obtaining fishes for food are: Marine fisheries In India, marine fishery is carried out along the 7500 km coastline and in the deep seas beyond. Fishing is done using fishing nets and boats. The amount of caught fish can be increased by locating schools of fishes using satellites or echo sounders. Some examples of marine fishes include mackerel, tuna, sardine, pomfret and Bombay duck. Some varieties of marine fishes are of high economic value. Finned fishes (such as pearl spot, bhetki and mullet) and shelled fishes (such as prawn, mussel and oyster) fall in this category. The cultivation of marine organisms for commercial purpose is known as mariculture. Inland fisheries Canals, ponds and rivers are some freshwater resources. Brackish-water resources are generally found where seawater and freshwater occur together. It includes estuaries and lagoons. Freshwater and brackish-water fisheries are called inland fisheries Pomfret and Mackeral are marine fishes and their culturing is done in sea water. While the Catla and Rohu are fresh water fishes and their culturing is done in fresh water.
