MAJOR FishING ZONES OF THE WORLD

1. NORTH-WEST PACIFIC :
this zone extends from the Bering sea in the north to the East China sea in the south.
Countries involved are: korea, philippines, china , japan.
Favourable factors :
- convergence of cold Oyashio & warm Kuroshio currents.
- indented coasts, Japan is the leading nation.
Important catches : cod, herring, tuna, salmon.

2. NORTH-WEST ATLANTIC :
this zone covers the coasts of Newfoundland, Novascotia & U.S.A. the zone extends from Newfoundland in the north to Long island in the south.
Favourable factors :
- wide continential shelf
- the presence of number of banks (zones of shallow water).
Fishing grounds / regions : the grand banks (southeast of newfoundland) , the sable bank (near novascotia) , george's bank near new england state.
Important catches : cod, herring, mackeral, halibut, haddock, flounders.
Chesapeake Bay is famous for Oysters' catches.
Fishing ports : halifax , St.john, boston, new york.

3. NORTH-EAST PACIFIC :
this zone extends from Alaska to California long the western coast of north america.
Important catches : salmon, herring, mackeral, sardines & tuna.
Fishing grounds : deep water off the british colombia , alaskan coasts in halibut.
Important Fishing countries : canada, u.s.a .
Important Fishing ports : anchorage, vancouver, san fancisco.

4. NORTH-EAST ATLANTIC :
this zone extends from Artic circle to Mediterranean sea.
Favourable grounds : north sea with dogger bank.
the warm current, north pacific drift keeps the region free from ice.
Important Fishing grounds : the north-est atlantic zone with shallow sea condition, & supply of plankton.
Important catches : cod, herring, haddock, mackeral.
Nations : norway, sweden, denmark, netherlands, france, u.k. , iceland.
the fiord coasts of norway provide the best Fishing sites. norway is called the 'land of fisherman'.

5. THE COASTS OF PERU & CHILE :
this area is having natural upwelling i.e. the cold bottom water rises to take the place of surface water moving away from the coast. this brings to more planktons ont the surface & hence more Fish. the major type of fish available here is small fish called as 'anchovy'.

Problems of Fishing :
1. over-fishing of a few particular species : Halibut & Salmon are today endangered species. the nets used for Fishing have small gaps that small & immature fish are also caught.

2. ocean transport : north atlantic ocean route is very busy route & passes through the north-east & north-west atlantic Fishing regions. the ships cause water-pollution & pose serious threat to fishing boats, nets .

nethraji,
is it the north pacific drift that is melting ice in north west ports of europe or is it north atlantic drift?
