Fisheries Best Journals

Regardless of purpose, however, the term fishery generally refers to a fishing effort centered on either a specific ecoregion or a specific species or sort of fish or aquatic animal, and typically fisheries are differentiated by both criteria.Examples would be the salmon fishery of Alaska, the cod fishery off the Lofoten islands or the tuna fishery of the Eastern Pacific.Most fisheries are marine, instead of freshwater; most marine fisheries are based near the coast. This is not only because harvesting from relatively shallow waters is simpler than within the open ocean, but also because fish are far more abundant near the coastal shelf, due to coastal upwelling and the abundance of nutrients available there. Fisheries are areas where fish are caught. Fisheries supply a large fraction of the world's food, but are under severe stress today from over fishing. Climate change may add to the stress on ocean fisheries by changing the planktonic food web that is the basis of the marine food chain. Changes in fisheries are associated with damage to coral reefs by water heating and ocean acidification, and other means. Fish populations are also shifting to different ranges because of warming water, with resulting changes in marine ecology and fishery populations. Climate warming affects freshwater fisheries by reducing dissolved oxygen, increasing stratification (layering of deep water), and shifting the patterns of rainfall that supply lakes and rivers with water.
