Age determination of Northeast Atlantic Sebastes species
Uncertainty exists concerning the validity of age determination methods for redfish species owing to the various procedures in use. North American scientists routinely use otoliths, whilst European scientists have preferred to use scales for aging commercial rockfish and redfish species. This study...
