Le modèle de délai différentiel de Deriso a été utilisé pour évaluer la biomasse des 7 ans [et plus] pour le stock [de poisson] d'automne en utilisant un indice de taux de capture combinant les âges pour calibrer le modèle. [...] ce modèle surestime à chaque année, de façon consistante, la taille du stock, mais les estimations de biomasse de 1992 n'ont pas changé quand le point de donnée de 1993 a été ajouté.
