Evaluation of the green abalone Haliotis fulgens fishery in Bahia Asuncion, Baja California Sur, Mexico

The fishery of green abalone in Bahia Asuncion, Baja California Sur (Mexico), was analyzed with an age-structured simulation model using data on catch, effort, abundance estimates, natural mortality and the population growth parameters (k, L(∞), t₀, a and b of the length-weight relationship, age at first capture and longevity). The parent-recruit relationship can be established from the correspondence between the adult stock and the one-year-old juveniles and was analyzed as a random variable with normal distribution; it shows anomalies with a sinusoid pattern. Estimates of potential yield show that current yields are below the biologic maximum sustainable yield and economic maximum sustainable yield levels.
