Population structure of Martialia hyadesi Cephalopoda Ommastrephidae at the Antarctic Polar Front and the Patagonian Shelf, South Atlantic



Population structure of Martialia hyadesi Cephalopoda Ommastrephidae at the Antarctic Polar Front and the Patagonian Shelf, South Atlantic



Bulletin of Marine Science 49.1-2: 404-418



Samples of the ommastrephid squid Martialia hyadesi were collected aboard Japanese squid fishing vessels during exploratory fishing operations at the Antarctic Polar Frontal Zone (APFZ) near South Georgia in February 1989 and during commercial fishing operations on the Patagonian Shelf in March 1986. Specimens caught during daylight at the APFZ were smaller than those caught during darkness. Specimens caught at the APFZ during darkness were generally smaller and less sexually mature than those from the Patagonian Shelf. Principal components analysis of character indices revealed no discernible separation between the sexes or between specimens from the two areas. Comparison of means of individual character indices for specimens from the two areas revealed differences between some areas for some characters, but in several cases the possibility that these differences were size related could not be discounted. Statoliths from samples taken from the modal mantle length at the APFZ were sectioned to reveal growth rings. If the rings are deposited daily, as in some other squid species, the age of these specimens is estimated to be 9-12 months.
