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

Cephalopods are one of the most important fishery resources, whose fishery biological characteristics are extremely vulnerable to changes in the marine environment. The ocean is the main storage carrier of energy in the climate system. The changes of marine environmental factors in recent years were caused by frequent climate change events, and have directly or indirectly influenced the fishery biological characteristics and even fishery of cephalopods. Therefore, this study summarizes the impact of climate change on cephalopods from the three perspectives of reproduction, age and growth, and early life history, and put forward an outlook. The results showed that the fishery biological characteristics of cephalopods were easily affected by the occurrence of climate change events mainly through the marine environmental factors of temperature and primary productivity. At present, the objecrts of relevent researches were mostly economic species such as Ommastrephidae and Loliginidae, and most studys concentrated on the marine environmental factor of marine temperature. In the future, long-term marine environmental data of other factors should be applied into the researches for impact of climate change on other cephalopods species. The purpose of this study is to provide a theoretical basis for analyzing the impact of climate change events on fishery biological characteristics of cephalopods, and to provide scientific guidance for sustainable development of cephalopod fisheries under frequent climate change events in recent years.
