Abstract :

Specimens of yellowfin snook Centropomus robalito were collected from October 2015 to September 2016, from commercial captures in Cuyutlan lagoon, Colima, Mexico. The maximum value of TL was 34.0 cm and the minimum was 6.50 cm, total weight varied from 2.7 g to 390.00 g. Each year a fast growth band and a slow growth band are deposited on the sagittae, equivalent to one year of age. The growth index value of the weight–length equation was positive allometric: b = 3.140 with total weight data and b =3.146 with eviscerated specimens. Growth parameters obtained by Ford–Walford–Gulland method for TL were: L_¥= 39.55 cm, k = 0.208 years^–1, and t_o= – 0.806. The calculated asymptotic total weight was TW_¥= 590.1 g and the eviscerated asymptotic weight EW_¥= 529.2 g. Longevity value was 13.6 years. Data obtained by other authors were compared with those reported in this study.
