In order to extend the knowledge on the age and growth of antarctic fishes, the authors present herein the results of the data processing arising from samplings o f a species belonging to the Chaenichthyidae family, Champsocephalus gunnari.
The age determination of this species, was made using the otolith fine cutting technique. Through the reading of the growth rings the age classes corresponding to3, 4, 5 and 6 year old males and 3, 4 and 5 year old females were found. The growth curves were adjusted according to the classic model and were estimated as:
♂ Lt= 497.5 [1-e-0.39 (t-1.44)]
♀ Lt = 627.1 [1-e-0.19 (t+0.03)]
