摘要
近几十年来随着传统鱼类资源衰退,短生命周期种类的资源量和捕捞产量出现了增长,并已成为世界海洋捕捞业的重要捕捞对象,为使渔业资源可持续利用,必须制定合理的渔业管理计划,实现对渔业资源的科学管理。对渔业资源进行科学的评估是制定渔业管理计划的基础,渔业资源评估模型则是进行渔业资源评估的重要工具,对短生命周期种类资源进行科学评估和管理是一个极为重要的课题。但是短生命周期种类具有生命周期短、生长快、资源丰富以及产卵种群多的特点,资源量极易受海洋环境影响的独特的生活史特征,使得世界各国对短生命周期种类资源评估和管理的研究处在发展初期。本文首先介绍了短生命周期种类的生物学特点,接着简要介绍了传统资源评估模型的分类,最后详细阐述了目前应用于短生命周期种类的资源评估模型与方法,同时,本文对渔业资源评估模型中存在的问题进行了探讨,并对其未来的发展进行了展望。
With the decline of traditional stocks in the world during the last several decades, the stock size and fishing catch of short-lived species with short-life cycle appear to increase, and the short-lived species have been become one of the important fishing targets. In order to keet fishery resources sus- tainable, it is urgent to develop rational fishery management plans and conduct a correct fishery man- agement. The fishery management plans should be based on fishery stock assessment and fishery stock assessment models are important tools for fishery stock assessment. Therefore, it is an important topic for us to carry out making an assessment and managing the short-lived species. The lifestyle o{ short- lived species is featured by short life span （usually for one year）, semelparous, rich abundance and more cohorts, and its variable resources is easily affected by environmental condition, which presented particular problems for the assessment and management of the fisheries for us and also made the re- search of short-lived species resources assessment and management in the early stage of development. This study introduced the biological characteristics of short-lived species. Beside, we reviewed the fish- ery stock assessment models＂ structures, types. Finally, we concluded the models and methods which were used on short-lived species and provide the basis to develop better and more suitable models or methods for the short-lived species. Meanwhile, this paper discussed the problems in fishery stock as- sessment models and presented prospects of their future development.
