东海渔业资源结构指标的定量评估及其应用
Quantitative assessment and application of indicators for fishery resource structure in East China Sea
摘要
Abstract
East China Sea(ECS)has rich fishery resources,and is one of the main fishing areas in China.Under the influence of global climate change,environmental pollution and overfishing,the fishery resource structure in the ECS has undergone significant changes,including miniaturization,decreases in age.Therefore,the assessment of fishery resources in the ECS has become important to its fishery management.However,there has been no a scientific and reasonable indicator system to assess the fishery resource structure in the ECS,which has seriously affected the sustainable development of these resources.In this study,22 indicators of fishery resource structure in the ECS were measured based on data regarding fishery yield and fish functional traits,such as total yield,average suitable temperature,and average trophic level.The local environmental variables,fishing efforts and large-scale climate indices in the ECS were collected.An indicator-testing framework was applied to quantitatively assess the performance of these 22 indicators in terms of their response to multiple pressures.On this basis,we constructed a set of scientific and reasonable indicator system to assess the long-term dynamics of the fishery resource structure in the ECS.The final indicator system revealed that the fishery resource structure in the ECS has seriously deviated from its initial state during the study period.In addition,the change trajectory of the final indicator system was highly consistent with the temporal trend of fishing efforts,and the timing of changes in the final indicator system aligned closely with climate change events.The results of this study can provide reference information for the ecosystem-based fishery management in the ECS and promote the sustainable development of its fishery resources.关键词
