  5. INVESTIGATING LENGTH AT MATURITY OF ANTARCTIC TOOTHFISH (DISSOSTICHUS MAWSONI) BASED ON SCIENTIFIC OBSERVERS’ DATA

    Abstract:  Through generalised linear models, the gonadosomatic index of Antarctic toothfish in ... the Ross Sea region was shown to vary with latitude, length and month. Limitations of the scientific ... observers’ staging data were highlighted and GSI is recommended as a better indicator of maturity status in ... Antarctic toothfish. Reports of histological analyses of a small number of Antarctic toothfish showed ...
