Question

Explain different types of fisheries.

Answer 1

Generally, a fishery is an entity engaged in raising or harvesting fish which is determined by some authority to be a fishery.[1] According to the FAO, a fishery is typically defined in terms of the "people involved, species or type of fish, area of water or seabed, method of fishing, class of boats, purpose of the activities or a combination of the foregoing features".[2] The definition often includes a combination of fish and fishers in a region, the latter fishing for similar species with similar gear types.[3]

A fishery may involve the capture of wild fish or raising fish through fish farming or aquaculture.[2][4] Directly or indirectly, the livelihood of over 500 million people in developing countries depends on fisheries and aquaculture. Overfishing, including the taking of fish beyond sustainable levels, is reducing fish stocks and employment in many world regions.[5][6] A report by Prince Charles' International Sustainability Unit, the New York-based Environmental Defense Fund and 50in10 published in July 2014 estimated global fisheries were adding $270 billion a year to global GDP, but by full implementation of sustainable fishing, that figure could rise by as much as $50 billion.[7]

Answer 2

There are two types of fusheries-

Marine fisheries-

Sources of marine fisheries include 7500 km of coastal line and deep seas beyond it.

Popular marine fish varieties include Macerel, Tuna, Saradins and Mombay duck.

The marine fish are caught using many kinds of fishing nets through fishing boats.

Some marine fishes of high economical value are also found in sea water. E.g., mullets, bhetki, peral spots, shel fishes such as prawns, mussels and oysters etc.

Inland fisheries-

Fisheries which are present in fresh water resources include canals, ponds and reservoirs etc.

More intensive fish farming can be done in composite fish culture in this type of fisheries.

In this such a system a combination of five or six fish species are used in a single fishpond.
