Lumpfish, Cyclopterus lumpus, have historically been harvested throughout Atlantic Canada and are increasingly in demand as a solution to controlling sea lice in Atlantic salmon farms – a process which involves both the domestication and the transfer of lumpfish between geographic regions. Here, we have 70K SNP array data and whole genome re-sequencing data (WGS) for a variety of sample sites across the Northwest Atlantic. ... : We sampled 1115 individuals from 79 locations throughout the North Atlantic from 2009 to 2019 (Fig. 1a; S1) in conjunction with scientific research surveys (trawl and beach seines) and commercial fishing activities. Sampling locations included waters around Newfoundland (N=994), the Gulf of St. Lawrence (GSL) (N=108), waters around Grand Manan (N=13), and from the Gulf of Maine (N=83). Due to the different sampling approaches utilized, differences in the sexes and life stages collected were present. Research vessel surveys collected individuals using a bottom trawl and generally targeted adults of both sexes, commercial samples were largely adult females due to the selective nature of the fishery for roe, and coastal sites around Newfoundland (TNR, SPA, and NMS, Fig. 1a), sampled using a beach seine were juvenile lumpfish comprising both sexes. In all cases, fin clips were preserved in 95% ethanol for subsequent DNA extraction. For the 70K SNP array data, DNA extractions were performed using DNeasy Blood and ...
