Abstract:
The present work is the first contribution to the knowledge of Ray's bream (Bramabrama)
biology in the south Atlantic coast of Morocco, which is one ofthe most diverse marine
ecosystems in Africa. The aim of this study was to determine age and growth for 101 individuals
belonging to the species Bramabrama obtained in fisheries landings of the south Atlantic coast of
Morocco. Collected samples consisted of fish with the total length varying from 32.8 to 51.5 cm
and with total weight varying from 528 to 1648 g. Furthermore, the von Bertalanffy growth
curve was fitted and the length-weight relationship was calculated. For all lengths, the
relationship was linear with a correlation coefficient close to one. The weight-length relationship
shows a minor growth relationship and weight increases less than size. Age of each individual
was obtained by reading otoliths and age classes from III to XI were represented in the catches.
Age classes from VI to IX represented 81.1%, while age classes less than III and greater than XI
were not recorded for any sampled fish. |
