Vertical distribution, age and growth rate of Muraenolepis marmoratus Günther, 1880 (Gadiformes, Muraenolepidae) in the area of South Georgia (Antarctica)

Abstract

The abundance of Muarenolepis marmoratus increases with depth. In December 1987 and January 1988 in bottom trawl catches prevailed 19-23-cm-long specimens, belonging to the age groups V and VI. Growth rate was expressed with use of von Bertalanffy′s growth equation with the parameters: L∞ = 48.21 cm; K = 0.1188; t0 = 0.1939 year.
