Bæredygtigt fiskeri | Greenpeace Storbritannien

Decades of bad fishing practices have left our oceans in a tragic state. Many species which were once common-place are now threatened, dwindling to the point where there aren’t enough to catch and make a profit. Over 90% of predatory species like cod and tuna have already been caught and, according to the UN, 70% of fisheries are overfished.

Numbers of fish are dropping faster than they can reproduce and this is causing profound changes to life in our oceans. In reality, there aren’t plenty more fish in the sea.

Fiskeindustrien er blevet højteknologisk, og gigantiske skibe bruger sonar til at finde fiskeskoler med stor nøjagtighed. Kæmpe net fanger fisk i stort antal. Disse skibe er også flydende fabrikker med forarbejdnings- og pakkeanlæg til at håndtere deres fangst mere effektivt. Alt dette betyder, at der nu er kapacitet til at fange mange gange flere fisk, end der faktisk er tilbage.

Udvalgt bifangst genudsat fra dybhavstrawleren 'Chang Xing' i internationalt farvand i Tasmanhavet. Greenpeace støtter sammen med mere end tusind videnskabsmænd opfordringen til et moratorium for havbundtrawlfiskeri på grund af den enorme mængde havliv, der ødelægges af denne fiskemetode.

Overfiskeri tømmer havene

Efterhånden som traditionelle arter forsvinder, bliver andre arter målrettet og endda omdøbt for at gøre dem mere tiltalende. For eksempel blev den patagonske tandfisk genopfundet som den mere appetitvækkende navngivne chilenske havaborre. Flåder begiver sig også ud i fjernere farvande i Arktis og Syd oceaner for at hærge fiskebestande der.

Fiskemetoder, der bruges af disse skibe, er ofte meget ødelæggende. Bund- og bomtrawl trækker net hen over havbunden for at fange flade fisk som kulmule og tunge. Men de smadrer også alt på deres måde og ødelægger skrøbelige koralrev. Og de fleste fiskemetoder er meget vilkårlige og fanger mange andre arter ved et uheld. Denne bifangst omfatter skildpadder, hajer, delfiner og andre fisk, som ofte kastes døde tilbage eller dør i havet.

There’s a human cost too. Industrial fishing means small-scale fishers using more traditional methods are suffering. In the UK, smaller boats are finding it hard to make enough money and communities in many fishing ports are economically deprived. The number of fishers has also halved in the last 20 years. Elsewhere in the world, people who depend on fish for food and income are seeing their stocks disappear as foreign vessels trawl in their waters.

Urimelige fiskekvoter

Den måde, hvorpå den britiske regering tildeler fiskekvoter, spiller en stor rolle i dette. Kvoter er blevet koncentreret i hænderne på et lille antal multi-million pund virksomheder. Kun fem familier kontrollerer næsten en tredjedel af de britiske fiskekvoter, og mere end to tredjedele af fiskekvoterne kontrolleres af kun 25 virksomheder. Sammenlignet med mindre fiskerioperationer beskæftiger disse store virksomheder færre mennesker, bruger mindre bæredygtige fiskemetoder og færre penge kommer ind i lokale økonomier.

Vores regering har allerede magten til at ændre den måde, den fordeler kvoter på. Greenpeace kæmper for et mere retfærdigt tildelingssystem, der favoriserer lokalt, bæredygtigt fiskeri, som vil bidrage til at skabe arbejdspladser og give fiskebestandene mulighed for at komme sig.

We’re also taking on the corporate giants plundering our oceans. Thai Union, the biggest tuna company in the world and owner of John West, was turning a blind eye to appalling conditions for workers and destructive fishing practices. But then an outcry from thousands of people around the world forced Thai Union to clean up its operations.

Og vi skal skabe flere beskyttede områder på havet. Et netværk af havets helligdomme vil give tilflugtssteder for fisk og andet havliv, så de kan trives væk fra truslen fra industrielle fiskerflåder. Med klima forandring skaber andre trusler mod vores oceaner, er vi nødt til at give dem al den hjælp, vi kan.

An Indonesian crew member displays a turtle caught on the end of a bait line of a Korean longliner, the 'Shin Yung 51'. The location is within the Exclusive Economic Zone of the Republic of Kiribati. Sharks, turtles, dolphins and albatrosses can often end up as unfortunate by-catch of longline fishing. Greenpeace are on the Pacific Leg of the 'Defending Our Oceans' global expedition. They are calling for an immediate end to pirate fishing, a 50% reduction in the amount of Pacific tuna caught, and a global network of Marine Reserves. Yellow Fin and Big Eye tuna stocks in the Central and Western Pacific are destined to be critically over-fished within three years if the relentless fishing of the two Tuna species continues at current rates. © Greenpeace / Alex Hofford
A Vietnamese crew member releases a shark back into the ocean which was caught on the end of a bait line of a Korean longliner, the 'Shin Yung 51'. whilst fishing for tuna. The location is within the Exclusive Economic Zone of the Republic of Kiribati. Sharks, turtles, dolphins and albatrosses can often end up as unfortunate by-catch of long-line fishing. Yellow Fin and Big Eye tuna stocks in the Central and Western Pacific are now drastically low due to pirate fishing and the over fishing of stocks by foreign, industrial nations. Local fishermen struggle to compete in these waters as sophisticated fishing equipment puts them out of business. Greenpeace are calling for an immediate end to pirate fishing, a 50% reduction in the amount of Pacific tuna caught, and a global network of Marine Reserves to tackle the problem of over fishing. © Greenpeace / Alex Hofford

Bottom-trawling boats, the majority from EU countries, drag fishing gear weighing several tonnes across the sea bed, destroying marine wildlife and devastating life on underwater mountains - or 'seamounts'. © Greenpeace / Kate Davison
Schools of fish circle a fish aggregating device (FAD) in the Western Pacific Ocean. Around 10% of the catch generated by purse seine FAD fisheries is unwanted bycatch and includes endangered species of sharks and turtles. The catch of large amounts of juvenile bigeye and yellowfin tunas in these fisheries is now threatening the survival of these commercially valuable species. Greenpeace is calling for a total ban on the use of fish aggregation devices in purse seining and the establishment of a global network of marine reserves. © Paul Hilton / Greenpeace

Fishermen use pole and line fishing method to catch skipjack tuna. Pole and line fishing is a selective and therefore more sustainable way to catch tuna as only fish of a certain size are caught, leaving juveniles to grow to spawning age and replenish the stock in the future. Small bait fish are thrown over the side of the boat to lure the tuna to the water surface. The fishermen use the acceleration of the fish as they race to get their prey, hook them and fling them onto the ship's flat deck. © Greenpeace / Paul Hilton
Spanish Albatun Tres is 115 mt long and is the world’s largest tuna purse seiner. Vessels such as this travel from one fish aggregation device (FAD) to another and spread their huge nets to catch everything swimming around the FAD. Around 10% of the catch generated by purse seine FAD fisheries is unwanted bycatch and includes endangered species of sharks and turtles. The catch of large amounts of juvenile bigeye and yellowfin tunas in these fisheries is now threatening the survival of these commercially valuable species.

The fishermen pull the skipjack tuna fish onto the boat in Flores sea, East Nusa Tenggara. The fishermen in Larantuka are famous for using sustainable methods, pole and line, on fishing tuna. Pole and line fishing is a traditional method of fishing, unchanged for generations, and often used by local fishers in coastal communities, using live bait, the fishing targets surface schooling skipjack. © Jurnasyanto Sukarno / Greenpeace
