Annual survival probabilities of anadromous Arctic Char remain high and stable despite interannual differences in sea ice melt date
Throughout their range, anadromous Arctic Char (Salvelinus alpinus (Linnaeus, 1758)) support commercial, recreational, and subsistence fisheries that are important economically, socially, and culturally. However, drivers of interannual variation in survival in this species remain poorly understood....
