他说，他对澳大利亚本土鱼类的研究表明，鱼是一种聪明的生物，像其他动物一样知道如何躲避敌人和捕捉食物。
He says his studies of Australian native fish show fish were intelligent creatures that know how to avoid enemies and catch food like any other animal.
因为没有可利用的带诱饵的钩子来捕捉它们，个别的鱼没有被捕获，这导致过去人们低估了鱼类的数量。
Some individuals would therefore not have been caught, since no baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past.
海里已经没有足够的鱼来维持鱼类自身的生存，更不用说维持一项产业了。
There were no longer enough fish in the sea for the stock to maintain itself, let alone an industry.
