环境因素对南极磷虾资源分布影响的研究进展

A review:research progress on environmental factors affecting resource distribution of Antarctic krill

环境因素是影响南极磷虾Euphausia superba分布的关键因素,是研究南极磷虾渔场形成机理及渔情、渔汛预报的基础。为了准确评估磷虾的资源量,扩大对磷虾资源的开发规模,使磷虾能够成为可持续开发的生物资源,国内外学者持续开展了南极磷虾的资源调查,对磷虾的分类、资源量、分布、渔场和部分相关环境因素进行了研究,并取得了显著的进展。本研究中主要综述了环境因素,包括非生物环境因素和生物环境因素,对南极磷虾资源分布影响的研究进展,并对研究中提出的一些假说做了阐释,以期为今后环境因素对南极磷虾资源分布影响的进一步研究提供参考。

Environmental factors are the key factors that have great effect on distribution of Antarctic krill Euphausia superba,and the research foundation of formation mechanism of fishing grounds,fishing conditions and fishing season forecast.For decades,considerable efforts have been devoted and significant progress has been made to understanding krill life histories and the interaction of krill populations with regional circulation and other environmental factors in order to make an accurate assessment of the biomass of krill and to expand the scale of the exploration of krill resource.This view describes primarily the current status of the research expounding the relationships between krill distribution and environmental factors,including abiotic and biological environmental factors,intending to indicate what studies are available and where additional work is needed.The further explanations are mad for some hypothesis to provide the reference to further research on the impact of environmental factors on the Antarctic krill resources distribution.
