Population structure discovered in juveniles of Greenland halibut ( Reinhardtius hippoglossoides Walbaum, 1792)
Abstract Understanding the genetic differentiation among populations of most marine fish requires investigating the differences among spawning grounds. However, this can be challenging as spawning grounds for some species are not well known, or spawning fish are difficult to collect. An alternative...
