   The Impact of Fishing

  Fishermen- if fish stocks crash then fishermen will be out of a job. 

Consumers- Fish costs will rise and then only the rich can afford to eat fish. people will lose an important part of their diet.

Government- fishing is economically important and if the fish stalks crash then the economy will suffer. Also the fishermen will have no work and the government will have to give out welfare to them and find jobs for them.

The environment- over fishing has killed many species of fish and has disrupted the equilibrium of the ocean. fish can not repopulate faster then the rate of fishing to the population of fish keeps on lowering. As certain species are hunted down other fish that eat those fish will lose a very important part of there diet and die as well.

Mexico's fishing industry

     The shallow waters of the pacific coast  and large amount of plankton in waters cooled by the Californian current makes for good fishing in the northwest. Together Sinaloa (23%) and Sonora (22%) make for about 45% of the national total. Fishing economically important in Veracruz (8%) and Baja California (6%). 72% of the total annual catch of 1.5 million metric tons is landed at pacific coast ports such as Guaymas, Mazatlan, Tampico. and Campeche ( golf coast parts) account for a further 25% each. The last 3% is in inland lakes and rivers and fish farms.

    value wise the most important species are shrimp, tuna, and sardines. Fresh water fish farms are becoming more common, many are specializing in the production of high value species like trout and indigenous white fish.

    At the sea of cartes ( gulf of California) is one of the worlds top five seas in terms of ecological productivity and biological diversity. In the 1990's a long line fishing fleet began to operate off of Ensenada. A single long line boat may have 5 km of line with 600 to 700 baited hooks in total. The sword fish population outside of the 80 km protected zone were quickly depleted, leading fishing boat owners to apply for permits to catch shark inside the 80 km limits. Decades of commercial over fishing are causing total collapse of fishing stalks. As late as 1993 the area less then 5% of all Mexico's territorial waters produced about 75% of the nations total fish catch of 1.5 million tons has declined the fish population by 90% since then.
