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 ... applied to find a model for the age estimation from measurable fish and otolith parameters. The following ... formula was obtained: Age (days) = 131.24 + 27416.4*Otolith weight (mg) Using this equation the age of 237 ... fish was predicted.
