Hoover fishing' ban demanded to save North Sea stocks By Moira Whittle, Consumer Affairs Correspondent, PA News Large areas of the North Sea must be closed to industrial fishing if wildlife and table fish stocks are to be protected, environmental campaign group Greenpeace said today. A report -- Industrial Hoover Fishing: A Policy Vacuum -- said that species such as sandeels and Norwegian pout, which are caught in the ultra-fine nets used in industrial fishing, were important in the marine food web for cod and other fish. The actions of the industry, which was inadequately regulated, taking over half the weight of all fish landed in the North Sea -- combined with those of fishermen and predatory fish left little for seabirds and marine mammals, said the report which drew on 100 separate studies. A recent Unilever report estimated up to 60% of the diet of fish consumed by humans consisted of the industrial fish species, sandeels and Norway pout. Studies examining the diets of harbour porpoises, grey seals and common dolphins in Scottish water also concluded the species are heavily dependent on sandeels during summer months. Without immediate and serious action the North Sea marine environment would be unsustainable, concluded the Greenpeace report. And it recommended the closure of industrial sandeel fisheries in areas sensitive for wildlife, as well as those which extend into spawning, nursery and important feeding grounds for table fish. "What further evidence do we need before action is taken. The North Sea cannot sustain this onslaught any longer. Environment and fisheries ministers must act now or accept responsibility for destroying our seas," said Greenpeace fisheries campaigner Robbie Kellman.
