Summary

A preliminary study of the age and growth of the Brazilianflathead (Percophis brasiliensis Quoy et Gaimard 1824). Growth in length of brazilian flathead from the two areas, i.e.,Argentine – Uruguayan Coomon Fishing Zone (33°56′ – 38°56′ S) and El Rincón (38°40′ – 41°40′ S) was compared. Otoliths (Sagittae) were used for age determinatiuons. Total length at age means were used as input values for VBGF fitting by Allen’s method. The growth of the fish from the two areas showed significative differences. Theparameter K of fish from El Rincón was particulary lesser than that of the fish from Mar del Plata.
