到目前为止,人们对估计世界海洋生物资源的合理,最佳的捕获量(问题)已进行大量的研究工作。这些研究工作是建立在各种各样的方法,内容的基础,其中有:世界海洋水域基础生产力或初级生产力,饵料有机体(生物)随之接踵而来的有关各种鱼类的饵料系数,鱼类的生殖力、排卵量根据单位面积渔捞统计资料基础上推算总渔获量、声学测定及数学模型试验研究等等。近25年来,这方面的计算结果所获得的数据很不一致,并且波动的幅度大,即从6000万吨至2亿吨,就是说相差有2倍,甚至2倍多。显然与现在在世界海洋及其某些地区的(区域性)方面缺乏一系列资料有关,也与在计算时引入假设条件及存在其他因素有关。
So far, much research has been done on the rational and optimal capture of the world’s living marine resources (problems). These studies are based on a variety of methods and contents, including: basic productivity or primary productivity in the world’s marine waters, bait feeding organisms (organisms) followed by various fish-related feeding factors, fish Progeny, ovulation volume based on fishing statistics per unit area based on the total catch, acoustics determination and mathematical model test research and so on. In the past 25 years, the data obtained in this area have obtained very inconsistent data and have fluctuated greatly, from 60 million tons to 200 million tons, which means a difference of two times or even more than two times. Clearly related to the lack of a series of information now available on the (regional) oceans of the world and in some of its regions, as well as the introduction of assumptions and other factors in the calculation.
