Population structure discovered in juveniles of Greenland halibut (<i>Reinhardtius hippoglossoides</i> Walbaum, 1792)

Abstract Understanding the genetic differentiation among populations of most marine fish requires investigating differences spawning grounds. However, this can be challenging as grounds for some species are not well known, or difficult to collect. An alternative is collect juvenile in nursery habitats closely associated with potential Greenland halibut a deep-dwelling, commercially important at least two identified major offshore North Atlantic and weak across Atlantic. In study, we sampled juveniles from three sites representing Davis Strait area northwest one site northeast primary along western slope Barents Sea. We applied genotype by sequencing discovered 90 markers that could used assess four sites. The showed differentiation, supporting existence clusters. Additionally, found between samples implying more than northwest.
