Age-at-length of Patagonian toothfish from the Falkland/Malvinas Islands
Abstract: To provide an age-length key for use in modelling the age structure of the Patagonian ... toothfish stock around the Falkland Islands, we used otoliths to estimate the age of a sample of 1893 ... Patagonian toothfish (Dissostichus eleginoides) captured by trawl and in the longline fishery. We used a thin ... section grinding machine to reveal a transverse plane through the otolith nucleus and between ...
