原始语种摘要: Abstract(#br)The deepwater redfish Sebastes mentella has a wide distribution in the North Atlantic Ocean. In the Irminger Sea, there is evidence for two phenotypes (deep-sea and oceanic) of deepwater redfish. The two phenotypes have overlapping geographic distributions but differ in depth preferences. There are two hypotheses on deepwater redfish stock structure in the Irminger Sea. One suggests that mature individuals of a single stock segregate according to size and age and therefore that the phenotypes represent different life stages of the same stock. The other hypothesis suggests that there are two different stocks and that these stocks segregate mainly according to depth. Additionally, it is not clear whether the fish of the deep-sea phenotype in the Irminger Sea and those on the...
