Particularly damaging were the introduction of industrialised fishing, with for example snapper fishing peaking in the 1970s at more than 10,000 tonnes a year (though even in the 2000s, private fishing of this species is also a considerable factor, weighing in at 400-800 tonnes a year).
尤其具有破坏性的是工业化捕鱼的引进，例如鳖类的捕捞在20世纪70年代达到高峰，每年超过10000吨（仅仅在2000年，私人捕鱼就已有很大影响，每年要捕去400－800吨）。
