Abstract:   (335 Views)
This work which relates to the study of growth and biometrics is an essential tool for a better monitoring of the stocks of the Gilthead sea bream Sparus aurata on the coast of Kabylia: region of Tigzirt province of Tizi-Ouzou. The results showes that the annual growth of S. aurata is 3.4 cm (all sexes combined) while the growth parameters calculated by the Von Bertalanffy equation are established as follows: L∞=79.95 K=0.049 and to=-2.3. Our estimates showed that S. aurata would reach a weight of 165g to 22cm in total length after 3 years. Gilthead sea bream has an isometric growth proportional to the cube of the fish length. Regarding biometric parameters, the analysis of metric characters by the method of least squares made it possible to follow the relative growth of certain parameters of the body which prove acceptable because the value of the correlation coefficients is always greater than 0.90.
