摘要
头足类是海洋生态系统的重要能量载体,枪乌贼科物种因其可塑的生活史特征在近岸生态系统的动态变化中快速适应.为了全面了解枪乌贼科物种生活史特征,本文以全球重要经济型枪乌贼科物种为研究对象,从种群结构、洄游路线、年龄生长、繁殖特性、摄食特性及其与环境因素关系等方面进行了归纳和总结.雄性采用不同繁殖策略与雌性进行交配,雌性卵的大小和繁殖力呈负相关;浮游幼体的体型决定个体的渐近生长,暖水期和冷水期孵化群体的生长策略是为了适应栖息环境的季节性变化而做出的生长响应;摄食种类随生长发育由低营养级向高营养级转变,鱼类幼体是其重要的饵料生物;在全球气候变化背景下,近岸枪乌贼科物种更能适应环境的变化.未来应对枪乌贼科物种的种群结构、洄游路线、生长敏感性、繁殖策略和生态特性等进一步开展研究,以期为近岸枪乌贼的合理开发和科学管理提供参考依据.
Abstract
Squid is an important energy carrier for marine ecosystems,and the Loliginidae species quickly adapt to the dynamic changes of coastal ecosystems due to their plastic life history characteristics.It was found that males use different reproductive strategies to mate with females,and the size of female eggs is negatively correlated with fecun-dity.The asymptotic growth of individuals depends on the size of paralarva,and growth strategies of hatching in warm-and cold-water periods were featured by growth responses to seasonal changes of habitat.The food items are changed from low trophic to high trophic levels with growth,with important prey organisms of larvae and juveniles fish.In the context of global climate change,Loliginidae species are better able to adapt to environmental varia-tions.In the future,some research should be conducted on the population structure,migratory routes,growth sensi-tivity,reproductive strategies and ecological characteristics of Loliginidae species,in order to provide reference for the rational development and scientific management of Loliginidae species.
