Modelling the spatial distribution of Patagonian toothfish ( Dissostichus eleginoides ) by length and age around Heard Island and McDonald Islands on the Kerguelen Plateau
Over 27 000 fish caught around Heard Island and McDonald Islands (HIMI) on theKerguelen Plateau have been aged from sectioned otoliths in the Australian ageingprogram since 1999, comprising more than 47 000 individual reads from seven differentreaders. Extensive length and age data for Patagonian to...
