SUMMARY
Abundance indices by age group of albacore (Thunnus alalunga) caught by the Spanish troll fleet in the north east Atlantic were standardized using catch rate data from 4069 trips collected over the period 1981-1999. Standarized CPUE´s for age groups 1 to 4 were estimated through the General Linear M...

| Summary: | Abundance indices by age group of albacore (Thunnus alalunga) caught by the Spanish troll fleet in the north east Atlantic were standardized using catch rate data from 4069 trips collected over the period 1981-1999. Standarized CPUE´s for age groups 1 to 4 were estimated through the General Linear Modeling approach by applying the log-normal error distribution model. RÉSUMÉ Les CPUE par groupe d’âge du germon (Thunnus alalunga) capturé par la flottille de ligneurs espagnols de surface sont standardisées à partir de 4.069 sorties répertoriées entre 1981 et 1999. Les indices d’abondance relative pour les groupes d’âge 1 à 4 ont été estimés au moyen de l’approche du Modèle linéaire généralisé postulant une distribution log-normal d’erreurs dans les modèles. |
