Age and Growth of Pseudochaenichthys georgianus Norman, 1937 (Channichthyidae) from the South Georgia Area
Abstract: Age was determined on the basis of growth microincrements in otoltihs. A calibration ... subsample of 49 specimens (total length range: 3.9- 59.0 cm) was aged using optical sagittal and transverse ... otolith sections and/or acetate replicas. Age ranged from 138 to 2116 days. A multiple regression ... was applied to find a model for the age estimation from measurable fish and otolith parameters. The following ...
