Fishing

Every year, over 600,000 tonnes of fish are caught off the coast of the UK. They include:



Large fishing fleets may have a factory ship which cleans and freezes the fish. This means the fleet can stay out at sea longer and catch more. Modern ships use echo-sounding to trace fish shoals (groups). A beam of sound is sent down into the water and then echoes back off the fish. A computer detects where the echo comes from.

If fishermen catch too many fish, there will not be enough left in the seas for the future. This is called overfishing. To avoid it they:
  • use nets with large holes so that young fish can escape and breed;
  • are only allowed to catch their limited 'quota' of fish or spend a limited number of days a year fishing;
  • breed their own fish in fish farms.

Different people have different attitudes towards fishing:
  • divers and tourists like looking at fish swimming;
  • animal rights groups argue that farmed fish are over-fed and don't develop properly;
  • fishermen say that quotas are lowering the amount of money they can make from selling fish so are damaging their livelihoods.
