Larimichthys polyactis RAD-seq raw sequence reads. Larimichthys polyactis

The small yellow croaker (Larimichthys polyactis) is a commercially important fish species with high gene flow and its overwintering populations experience heterogeneous environment, suggesting possible population differentiation and adaptive divergence. To delineate patterns of population structure as well as test for signatures of local adaptation, a total of 68,666 quality filtered SNP markers were identified for 80 individuals from four overwintering populations by using Restriction site-associated DNA tags sequencing (RAD-seq).
