气候变化事件对头足类繁殖、年龄生长与早期生活史的影响研究进展

头足类是重要的渔业资源之一,其渔业生物学特性极易受到海洋环境变化的影响。气候中的能量主要储存载体是海洋,近年来频发的气候变化事件引发海洋环境因子变动,直接或间接地改变了头足类的渔业生物学特性,对头足类的渔业生产造成影响。为此,本文归纳和总结了气候变化对头足类繁殖、年龄生长与早期生活史三个方面的影响,并提出了展望。结果表明,气候变化事件的发生极易影响头足类动物的渔业生物学特性,海洋环境因子中的温度和初级生产力变动为主要影响因素。目前,相关研究对象多为柔鱼类和枪乌贼类等经济种,选用的海洋环境因子也多为海洋环境温度,今后应结合其它海洋环境数据研究气候变化事件对其它种类的影响。本文旨为研究气候变化事件对头足类渔业生物学特性的影响提供理论依据,为近年来气候变化事件频发下头足类渔业的可持续发展提供科学指导。

Review on the impact of climate change events on reproduction, age and growth and early life history of cephalopods

Cephalopod is one of the most important fishery resources, which its fishery biology characteristics were easily affected by marine environmental changes. Ocean was the main storage carrier of climate energy. The changes of marine environmental factors in recent years were caused by frequent climate change events, which have directly or indirectly influenced the fishery biology characteristics and even fishery of cephalopods. Therefore, three aspects in this paper were summarized in previous studies from reproduction, age and growth and early life history. The results were shown that the fishery biology characteristics of cephalopods were easily affected by the occurrence of climate change events mainly through temperature and primary productivity in marine environmental factors. At present, the objectives of correlated researches were mostly concentrated on Ommastrephidae and Loliginidae, and marine temperature was mostly used to select for analysis from major marine environmental factors. In the future, long-term marine environmental data should be applied into the researches for impact of climate change on other cephalopods species. The purpose of this study was to provide a theoretical basis for analyzing the impact of climate change events on fishery biology characteristics of cephalopods, and to provide scientific direction for sustainable development of cephalopod fishery under frequent climate change events in recent years.
