要合理利用海洋生物资源,首先必须对各种生物进行深入研究,掌握其数量变动规律,并提出预报和建议。根据资料收集的多少和研究程度的不同,预报可分为三类:1.收集了历年观察资料,在分析研究资料的基础上编制有充分根据的、常常可以用几种方法进行计算和验证的预报;2.收集资料时间不长,只有短期的或间断观察的资料,亦即根据不太充分的预报;3.收集资料较少,只能在分析水域平均生物量、间断调查或间接
In order to make rational use of marine living resources, we must first conduct an in-depth study on various living beings, grasp the law of their quantity changes, and make forecasts and suggestions. According to the amount of data collected and the different degree of research, the prediction can be divided into three categories: 1. The historical data collected over the years, based on the analysis of research data to develop a well-based, often several ways to calculate and verify Forecast; 2. collect information is not long, only short-term or intermittent observations, that is, based on less than adequate forecasts; 3. less information collected, only in the analysis of the average biomass of the waters, interim survey or indirect
