Otoliths morphology and age-record in Bagre panamensis (Siluriformes: Ariidae) inhabiting at the southeast of Gulf of California

ABSTRACT Among Bagre genera, there is a high variation in the estimation of age, a concern due to overexploitation risk in fisheries because of age underestimation. Bagre panamensis is an important fishery resource of the Mexican Pacific and the Gulf of California. Its age is known from otoliths, bu...
