Scientists inCanadasay big ocean fish have almost disappeared from the world since the start of industrial fishing in the 1950s. The scientists found that the population of large fish like tuna,swordfish and cod has dropped by ninety per cent in the past fifty years. The study took ten years. The researchers gathered records from fishing businesses and governments around the world. The magazine Nature pub?lished the findings.

The scientists say the common method called longline fishing is especially damaging to populations of large fish. This method involves many fishing lines connected to one boat. These wires can be close to one hundred kilometres long. They hold thousands of sharp metal hooks to catch fish.

Longline fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish every one hundred hooks. The study says longline fishing boats now might catch one fish per hundred hooks.

The scientists say industrial fishing can destroy groups of fish much faster than in the past. The study suggests that whole populations can disappear al?most completely from new fishing areas within ten to fifteen years.

Ransom Myers of Dalhousie University in Nova Scotia led the study with Boris Worm of Dalhousie and the University of Kiel inGermany. Mr Worm says the destruction could lead to a complete reorganization of ocean life sys?tems. Mr Myers says the decreased number of large fish is not the only worry. He says even populations that are able to reproduce do not get the chance to live long enough to grow as big as their ancestors (祖先) .He says not only are there fewer big fish,but also they are smaller than those of the past.

American government scientists say even with the best efforts to protect fish populations,decreases are to be expected.
