    Abstract
    • Estimates for the growth parameters (L sub( infinity ) and K) mortality coefficients (Z,M and F) and exploitation rate (E) for the sciaenid Plagioscion squamosissimus are presented. The following results were obtained: 1) for male: L sub( arrow right )=44.2 cm, K=0.30 yr super(1), Z=0.82 yr super(1), M=0.66 yr super(1), F=0.16 yr super(1), and E=0.20; and 2) for females: L sub( arrow right )=68.4, K=0.22 yr super(1), Z=0.91 yr super(1), M=0.47 yr super(1), F=0.44 yr super(1) and E=0.49. Females are more heavily fished than males. Artisanal fishing carried out with gillnets, is mainly directed toward the young section of the population and individuals reproducing for the first time.
