摘要
利用分层抽样方法进行海洋捕捞渔业统计,能客观有效地收集相关渔业数据,并能推算出各捕捞作业类型的渔获量。本文介绍了分层抽样的设计方案,着重对如何收集捕捞渔业结构信息,如何对总捕获量、单位日渔获量、效益以及捕获鱼种统计的计算方法进行了概述,对渔业统计人员如何开展抽样调查发挥一定指导作用。
Application of stratified sampling method in small scale fisheries statistics, which can objectively and effectively collect fishery statistics needed data, and can calculate the catches in the fishing operation.
