我们要对海洋渔业进行有效的管理,如保护某种鱼、虾的繁殖和生长,或者培养一些海洋动物的实验,开展某种经济动物的养殖,或防止某种有害动物的传佈,那么对这些动物幼体的培养试验或生活史的研究是必要的。只有从这方面的研究结果中,我们才能掌握它们的生存和发展的规律,才能加以适当的控制,满足我们的要求。但是要得到圆满的研究结果,首先就得考虑如何 We need to effectively manage the marine fisheries, such as the protection of certain fish, shrimp breeding and growth, or to develop experiments on some marine animals, to carry out farming of some kind of economic animals, or prevent the transmission of certain pests, then these Animal larvae culture test or study of life history is necessary.

But to get a satisfactory result, you have to think first of all
