SLAF-sequencing of wild and artificial selected oceanic-salinity adaptive populations of estuarine oysters (C. ariakensis)

In 2017, we initiated an artificial selective breeding program to improve the oceanic salinity (about 30) resistance of estuarine oysters to develop its farming industry in Northern China. Six-month-old oysters were collected from an artificially selected population (G5) cultured in a sea area (oceanic salinity), as well as a self-propagating wild population in the estuary without artificial high salt stress. Both populations (50 individuals each) were collected from Binzhou City, Shandong Province, China. Reduced-representation genome sequencing (SLAF-seq) was performed for 50 individuals from each population.
