Population genomics reveals a mismatch between management and biological units in green abalone (Haliotis fulgens).

摘要: Effective fishery management strategies should be based on stock delimitation and knowledge of the spatial scale at which species are distributed. However, a mismatch often occurs between biological units resources. The green abalone (Haliotis fulgens) supports an important artisanal in west coast Baja California Peninsula (BCP), Mexico, has shown declining tendency despite several measures. Thus, aim this study was to characterize patterns neutral genomic variation along BCP test whether structure support current areas. To hypothesis, set 2,170 putative single nucleotide polymorphisms discovered by double digest restriction-site associated DNA approach used 10 locations BCP. results revealed population with three groups: Guadalupe Island northern southern locations. contemporary gene flow might explained local oceanographic features, where it is bidirectional within region but predominant southward from region. These findings indicated that administrative areas did not match H. fulgens fishery; hence, assessment revised.
