Regional declines in blue shark abundance have been detected using both fishery-dependent and fishery independent data, raising concerns about the status of the stocks. However, the stock structure of P. glauca is largely unknown despite its importance as a fishing resource. The project aims to accurately delineate stock structure and elucidate the movement patterns in the blue shark Prionace glauca in Atlantic waters, using a combination of state-of-the-art technology in molecular genetics (NGS and SNP genotyping) and in electronic tracking devices (SPOT tags). The expected outcomes of this study have direct application in the fisheries management of this highly exploited pelagic shark.
The project aims to accurately delineate stock structure and elucidate the movement patterns in the blue shark Prionace glauca in Atlantic waters, using a combination of state-of-the-art technology in molecular genetics (NGS and SNP genotyping) and in electronic tracking devices (SPOT tags). Molecular markers will be screened in samples of young of the year and juvenile blue sharks sampled at the reported Atlantic nursery areas to maximize the probability of detecting a signal of genetic population differentiation. In addition, SPOT tags will be deployed on adult female blue sharks caught at the reported Atlantic nurseries and used to track individual movement over a 12 month+ period to infer their movement and habitat use patterns.
