Overfishing and Pollution
Summary: The following provides an outline about overfishing and pollution all over the world.
OVERFISHING AND POLLUTION
- The world's sea fisheries are damaged by yields above about 80 millions tonnes.
- The FAO reports that production of fish has reached a plateau in most of the major fishing area and is in decline in some of them
- Production levels are being maintained by catches of younger fish which is bound to reduce stocks in the longer term
- Crustaceans(lobsters,shrimp,crabs etc) are generally heavily exploited
- Demersal fish (cod, plaice, and haddock) are already fully exploited.
- Small pelagic fish (herrings, mackerel, pilchards) are seeming pessimistic for being overfished
- Tuna species appear to offer potential for increased production
- Deepwater species offer great potential, however these fish can live for up to 100 years and take 20 to 25 years to reach maturity.
- In the last decade, overfishing has partly been due to the technique of large scale Driftnetting
- Driftnetting produces high catches, but also results in the by-catch'...
