Una crítica de las curvas de reproducción

[ES] Una gran dificultad en la evaluación de poblaciones de peces es la inconsistencia de la relación entre el esfuerzo de pesca y la mortalidad por pesca, debido a que el comportamiento de los peces, especialmente de los pelágicos, está muy influido por los cambios ambientales, ya sea a corto plazo (vulnerabilidad) o a un ritmo anual (disponibilidad).

[EN] A simulation model is proposed to analyse parameters of reproduction curves. Ricker and Beverton-Holt models are examined. Parameters related to density-independent mortality depend on physiological-constitutional (genetic) factor and on the ecological niche. [...] Sardina pilchardus, Oncorhynchus
