  2. 2. History Dietary Importance of Fisheries
  3. 3. International trends  Fisheries in global prospect ( Diet, Employment, Economic)  World fish production: 130 M. Ton (37 M. Ton Aquaculture, 92 M. Ton captured) 2001  China is leading: ( 42 M. Ton Total production, 33% of world), (16 M. Ton Aquaculture, 26 M. Ton captured), ( 69 % aquaculture of world)  38% world fishes traded  74 % diet use, 26% non diet use  200 M employment  950 M people’s primary diet  Problem of over fishing ( limit:100 M. Ton, Requirement increasing, Aqua culturing is need of time)
  4. 4. Trends in Pakistan  Rich in resources  Fisheries department is neglected  0.8 % GDP,  0.25 % of world production,  70% of caught fish is exported ( 1.6 kg /person/year fish demand as compared to world 16 kg/person/year)  1 M people involved
  5. 5. Marine fisheries in Pakistan  100 Km coast line with Arabian sea  Important areas of Sindh, Makran, Balochistan  Subtropical zone  30 sp. of fish, 10 sp. of crabs, 5 sp. Of lobsters, 70 commercial fishes  Sardine, Hilsa, sharks, Makerel, Butterfly fish, Pomfret, Sole, Tuna, Sea bream, Cat fish, Eel etc.
  6. 6. Fishing Zones:  200 Nautical miles area:  Coastal fishing zone: 1-12 NM ( for local fisher men, with small boats, old techniques)  Deep sea fishing zone I: 12-35 NM (For Fishermen with large boats and modern equipment)  Deep sea fishing zone II: 35-200 NM (For foreign, Pakistani vessels, with license from government)
  7. 7. Fresh Water Fisheries in Pakistan  Rich land with inland waters — reservoirs, canals, swamps, lakes, streams and rivers  Drainage Basin for Himalaya Mountains  Natural lakes: Area of 109,780 hectares  Cold water lakes: (Saif-ul- Mulook, Satpara, Hanna),  Warm water lakes: (Manchar and Kalri ).  The Indus:  Five large rivers — Kabul, Jhelum, Chenab, Ravi, and Sutlaj  There are 3,300 fish farms in the country in Punjab and Sindh.
