One million metric tons of fish thrown away annually in US

Wednesday, February 24th, 2010

For every 5 pounds of fish caught by US commercial fisheries, one pound is dumped dead and wasted. More than one million metric tons of fish is thrown away annually in USA. A Gulf of Mexico shrimp fishery discards 472,000 metric tons or one billion pounds of fish. Shrimp and fish trawl fisheries are responsible for 78% of all discards in US fisheries.

Sharks have existed for 400 million years. Now, only two sanctuaries are left for sharks. Though sharks kill only 5 people annually, humans kill 100 million sharks annually for a billion dollar shark industry.

Global marine protection would cost less than current commercial fishing subsidies

Wednesday, February 24th, 2010

Bottom trawling can plough furrows up to 6m wide and 150cm deep, for many kilometres across the seabed. Some areas are trawled this way five times a year; they are turned over much more often than arable fields. This has had a disastrous effect on the habitat that extends from below to the seabed to a short distance above it, and for the species living there.

A recent survey found that running a global system of marine protected areas covering 30% of the oceans would cost between £6.5 and £7.5 billion a year. This is less than the £8 to £16 billion spent globally each year on subsidies to commercial fisheries.

Only 4% of world’s oceans free from human impact: 40% heavily impacted

Thursday, February 18th, 2010

Only 4% of world’s oceans remain free from human impact in 2008, according to a study in the journal Science, and 40% have been heavily impacted. One-tenth of sharks, tuna, cod and other predators have disappeared, affecting the marine food system. Those fish that eat starfish have disappeared, thus starfish numbers multiply, and they graze on coral resulting in larger reef disappearance in the past 30 years.  There has also been a large rise in algae, bacteria and jellyfish populations due to a lower number of predators.
