Does the timing of the spawning migration change for southern component of North East Atlantic Mackerel (Scomber scombrus, L. 1758)? A approximation by the fishery analyses
Part of the Northeast Atlantic mackerel population migrates towards the southern spawning area (Cantábrian Sea) at the end of winter. In this seasonal handline fishery targeting mackerel, the most important in the study area that targets this species, the timing of the peak of catches has shifted fo...
