A halving
of the worlds’ fishing fleet by 2005. Measures
to eliminate bycatch and prevent further damage to marine biodiversity.
Ratification and implementation of the 1995 UN fisheries Agreement.
UN figures indicate that most major
fisheries are over exploited. One quarter of all marine life caught worldwide is thrown back dead
Marine fishing generates about 1% of
the global economy and supports the livelihoods of around 200 million
people.
As little as 2% of the original
Southern Bluefin Tuna (SBT) population remains.
90% of SBT caught is traded on Japanese
markets.
Scientists predict that the Patagonian
Toothfish could be commercially extinct by 2002, if current fishing
levels continue.
In 1997, the illegal catch of
Patagonian
Toothfish was around 100,000 tonnes and worth more than $500 million.
Scientists estimate that illegal
fishing for Patagonian Toothfish was responsible for the deaths of over 100,000
seabirds mostly albatrosses and petrels) in 1997. At least 44,000 albatross are killed
annually on tuna longlines.
Many small crustaceans and shellfish are killed and their
habitats destroyed by repeated trawling over the same area.

Fishing may
be an ancient tradition, but sophisticated technology and a
global boom in the industry during the past 50 years have out-stripped
nature’s ability to replenish the seas. Wasteful and destructive
fishing practices are decimating global fish stocks, damaging marine
ecosystems, threatening food security, economic stability, and the
livelihoods of tens of millions of people. Around the globe some one million
industrial scale and two million smaller fishing boats compete for what
remains of
dwindling fish stocks. Wasteful and indiscriminate fishing methods -
vast trawler nets large enough to hold several aeroplanes; mammoth
factory ships capable of catching and processing several hundred tonnes
of fish every day; fishing lines up to 130 kilometres long and dripping
in thousands of baited hooks -threaten the delicate web of marine life.
It is estimated that about 27 million tonnes of dead and dying ocean
creatures, caught as unwanted bycatch, are thrown back into the oceans
every year. Overfishing is not simply a question of running out of fish,
but of the potential collapse of the entire ocean ecosystem. And it
isn’t only those creatures beneath the waves that are at risk from
modern fishing. The albatross, the world’s largest flying bird, is
also threatened by commercial fishing. Thousands of albatross die each
year when, attracted by longline baits sitting just below the surface of
the water, they are hooked, dragged underwater and drowned. At least
44,000 albatross are killed every year by longline fishing vessels
operating in the southern hemisphere. |
