Pakistan has many marine and inland fishery resources. The potential was estimated at 1 million tones/year from the marine subsector alone. The commercially important resources include near 250 demersal fish species, 50 small pelagic fish species, 15 medium-sized pelagic species and 20 large pelagic fish species. In addition, there are also 15 commercial species of shrimp, 12 of cephalopods and 5 of lobster. The effect of the Indus River Delta on the marine resources of the coastline of Sindh is substantial, as this river system has been transporting enormous quantities of nutrients and sediment to the continental shelf for centuries. Pakistan has an extensive inland water areas system, which is mainly dominated by the Indus River. These water bodies, depending on their type, possess varying potential for development of the inland and aquaculture subsectors. Inland water bodies, like dams, water locks, reservoirs, rivers, lakes and ponds cover an area of approximately 8 million hectares.
