摘要

The jumbo flying squid Dosidicus gigas is widely distributed throughout the Eastern Pacific Ocean, where it plays a critical role in the marine ecosystem. This squid has high economic value and is an important fishing target for global cephalopod fisheries. At present, D. gigas is strictly regulated through the South Pacific Regional Fisheries Management Organization. As a short-lived squid species, climate variability in combination with certain oceanographic conditions substantially affects its life history, abundance, and habitat distribution. Here, we present a literature review of the fishery status and main life history processes of D. gigas and a summary of its ecological responses to multi-scale climatic and environmental changes. In this review, D. gigas fisheries are examined, with a specific focus on China. Life history of D. gigas including population structure, age growth, migration, reproduction, and feeding are summarized and their relationship with climate clarified. The impacts of climate variability on the spatial and temporal distributions of D. gigas habitats are also reviewed, highlighting the critical impact of climatic and environmental changes on the life history and distribution of D. gigas, which greatly challenges fisheries management. Our findings suggest that adaptive management measures for D. gigas fisheries should be proposed to mitigate and adapt to the effects of climate change. The following steps are suggested: (1) strengthening the monitoring of anomalous climatic events and the assessment of their impacts; (2) strengthening international cooperation to establish a monitoring system for D. gigas abundance in the Eastern Pacific and develop long-term forecasting techniques; (3) developing an assessment model for D. gigas that integrates climatic factors and examines different potential management strategies; (4) increasing awareness and guidance on the impacts of climate change and establishing climate adaptive fisheries management measures.
