Catch-at-size (CAS) data are important inputs for many stock assessment methods. However, for methods such as virtual population analysis (VPA), catch-at-size are often first converted into catch-at-age (CAA) by age slicing using a deterministic growth model. 4, record 1, English, - catch%2Dat%2Dage

Les données de prise par taille (CAS) constituent d'importantes valeurs d'entrée pour de nombreuses méthodes d'évaluation des stocks. Toutefois, dans le cas des méthodes telles que l'analyse de population virtuelle (VPA), les prises par taille sont souvent converties dans un premier temps en prise par âge (CAA) obtenue par le découpage des âges au moyen d'un modèle de croissance déterministe. 2, record 1, French, - prise%20par%20%C3%A2ge

After a fish population has been parameterized in terms of its vital rates(age-specific fecundity and survival) and intrinsic variability, one needs to set a starting population for each age class at time [t=0]. Most often, initial abundances are based on field sampling data for the target fish species. 3, record 4, English, - starting%20population

Les scientifiques utilisent l'effectif par classe d'âge afin de déterminer le nombre de poissons présents dans le stock au début de l'année étudiée et de réactualiser les résultats des années précédentes. Les résultats pour les classes d'âges les plus anciennes sont donc très fiables puisqu'ils sont recalculés tous les ans avec les nouvelles données de captures. Ils le sont moins avec les classes d'âge les plus récentes. 1, record 6, French, - effectif%20par%20classe%20d%27%C3%A2ge
