Overfishing in Britain and the USA

Bleak warning that UK fish face extinction

* Tuesday October 14 2008

A hidden catastrophe is unfolding off the coasts of Britain which could leave our seas filled with only algae and jellyfish, a leading conservation organisation warns today. The Marine Conservation Society says severe overfishing is the biggest environmental threat facing Britain and is having a profound effect on marine ecosystems. The warning comes in Silent Seas, a report released as the government prepares its marine bill for parliament.

The report comes the day after the International Council for the Exploration of the Seas, which advises Europe’s politicians on fish stocks, warned that parts of the North Sea should be closed to mackerel fishing because stocks of the species could be on the brink of collapse. …

The report said the rate of loss of fish in British seas was accelerating, with formerly abundant species such as the common skate appearing on lists of endangered species. Only eight of the total of 47 fish stocks found around the British Isles remain in a healthy state, the report says, adding that the size and quality of the fish is falling as younger fish are taken out of the sea: “A hundred years ago a large plaice had to be 50-60cm long and weigh 1.5-2kg to be considered big. Today plaice fillets are sold as ‘large’ when they weigh just 125g. Fish this size have never had a chance to breed.”

From Greenpeace:

Bering Sea, United States — The world’s largest food fishery is on the verge of collapse. Pollock, used to make McDonald’s fish sandwiches, frozen fish sticks, fish and chips, and imitation crabmeat, have had a population decrease of 50 percent since last year.

  1. Mislabelling drives skate to brink of extinction

    Due to an 83-year-old error of classification, a species of European skate could become the first marine fish driven to extinction by commercial fishing, according to a study released Wednesday.

    PARIS (AFP) – Due to an 83-year-old error of classification, a species of European skate could become the first marine fish driven to extinction by commercial fishing, according to a study released on Wednesday.

    In the 19th century, scientists identified two separate species of the once-widespread European skate, the flapper skate (Dipturus intermedia) and the blue skate (Dipturus flossada).

    But an influential study in 1926 argued the two species were in fact one, which prompted a new name, Dipturus batis.

    Since then, trawling has massively depleted all types of European skate stocks, with France accounting for more than 60 percent of landings.

    New research, led by Samuel Inglesias of France’s Museum of Natural History and using molecular analysis of DNA, proves once and for all that the initial classification was correct.

    As a result of the overfishing, the flapper skate is on the fast track to being wiped out, the paper says.

    “[Without] immediate and incisive action, the species may be in an irreversible decline towards extinction,” Inglesias said in a statement.

    The blue skate is in sharp decline but is still a viable species, the study says.

    Iglesias said the discovery highlights the need “for a huge reassessment of population for the different Dipturus species in European waters.”

    The study was published in the journal Aquatic Conservation: Marine and Freshwater Ecosystems.
