摘要
渔业资源的可持续利用是世界各国学者关注的重要话题,渔业资源科学评估是可持续发展的必要条件.生物因素、非生物因素是引起生物资源量变动的重要原因,资源评估与管理工作中绝大多数忽视非生物因素对资源变动的影响,而生物群体对环境变化较为敏感,特别是早期生活史阶段,环境不仅影响物种的生长发育,还强烈影响其空间分布和洄游等,对渔业资源数量产生影响,评估未考虑环境作用也相对增加评估结果不准确性的风险.本研究对加入环境因子的渔业资源评估模型、评估模型中环境因子与模型参数的关系、模型应用等方面进行全面总结.分析认为开发基于环境因子的渔业资源评估模型,要将气候驱动的环境变化纳入资源评估中,确保渔业资源评估和管理能够适应气候和环境的变化,为资源可持续利用提供科学依据.
Abstract
The sustainable use of fishery resources is an important topic of concern among scholars a-round the world,and the scientific assessment of fishery resources is a necessary condition for sustain-able development.Biotic factors and abiotic factors are important causes of changes in the amount of fisheries resources.In resource assessment and management,most of the work ignores the impact of abiotic factors on resource changes.Poulation are sensitive to environmental changes,especially in the early life history stage.The environment not only affects the growth and development of a species,but also strongly affects theirdistribution and migration,which has an impact on the abundance of fishery resources.Failure to consider environmental effects in the assessment also increases the risk of inaccu-rate assessment results.In this study,we comprehensively summarized the fishery resource assessment model with environmental factors,the relationship between environmental factors and model parame-ters in the assessment model,and the application of the model.We believe that developing a fishery re-source assessment model based on environmental factors should incorporate climate-driven environmen-tal changes into the resource assessment to ensure that the assessment and management of fishery re-sources can adapt to climate and environmental changes and provide a scientific basis for the sustainable resources utilization.
