渔业因缺乏限制其发展的规章制度及该领域里巨大的技术进步,而使其资源量锐减。过度捕捞已不是新问题了,1946年在伦敦召开的第一次国际会议就着手进行处理。当时只涉人到北大西洋和北太平洋:它们占世界上有案可查的捕捞量的80%以上。从此,过度捕捞在更便利的航行、更好的渔网和冷藏设备,以及先进的卫星技术的辅助下,逐渐漫延到了每一个海洋。美国近来又建成一种数据库,以惊人的清晰度展示海底世界。这样的手段使渔船敢于走得越来越远,到以前进不去的水域捕鱼,比如到被称之为地下山脉的水域。渔船现在能用船载计算机贮存信息,在电子仪器 Fisheries have caused their resources to drop sharply due to the lack of rules and regulations that limit their development and the huge technological advances in this area. Overfishing is no longer a new problem, and the first international conference in London in 1946 set out to deal with it. At that time, they involved only the North Atlantic and the North Pacific: they accounted for more than 80% of the world's documented catch. Since then, overfishing has been spreading over every ocean with more convenient navigation, better fishing nets and refrigeration equipment, and advanced satellite technology. The United States recently built a database that shows the underwater world with amazing clarity. Such means make the fishing vessels dare to go farther and farther, fishing to the waters that they can not go forward, for example, to the waters called the underground mountain ranges. Fishing boats are now able to store information on board computers in electronic equipment
