Age, growth and maturation of the squid Martialia hyadesi (Cephalopoda, Ommastrephidae) in the south-west Atlantic
The statolith microstructure was studied in 142 females (mantle length, ML, ranging from 77–402 mm) and 119 males (72–328 mm ML) of Martialia hyadesi caught on the Patagonian and Falkland shelves and at the Antarctic Polar Frontal Zone between 1989–94. The statolith microstructure dark zone in this...
