STANDARDIZED CATCH RATES FOR BLUE MARLIN (Makaira nigricans) AND WHITE MARLIN (Tetrapturus albidus) FROM THE US RECREATIONAL TOURNAMENTS FISHERY IN THE NORTHWEST ATLANTIC AND THE GULF OF MEXICO

Indices of abundance of blue marlin (Makaira nigricans) and white marlin (Tetrapturus albidus) from the United States recreational billfish tournament fishery are presented for the period 1973-1999. The index of weight (kg) per 100 hours-fished was estimated from numbers of billfish caught and repor...

Description
Summary:Indices of abundance of blue marlin (Makaira nigricans) and white marlin (Tetrapturus albidus) from the United States recreational billfish tournament fishery are presented for the period 1973-1999. The index of weight (kg) per 100 hours-fished was estimated from numbers of billfish caught and reported in the logbooks submitted by recreational tournament coordinators and NMFS ob-servers under the Recreational Billfish Survey Program. The standardization analysis procedure included the following variables: Year, Area, and Season. The standardized index was estimated using Generalized Linear Mixed Models under a delta-lognormal model approach. RÉSUMÉ Le présent document présente les indices d’abondance du makaire bleu (Makaira nigricans) et du makaire blanc (Tetrapturus albidus) capturés par la pêche sportive américaine pendant la période 1973-1999. L’indice en poids (kg) par 100 heures de pêche a été estimé d’après le nombre d’istiophoridés capturés et déclarés dans les livres de bord remis par les organisateurs des championnats sportifs et les observateurs du NMFS dans le cadre du Recreational Billfish Survey Program. Le processus de standardisation analytique comprenait les variables suivantes: année, zone et saison. L’indice standardisé a été estimé au moyen de modèles linéaires généralisés mixtes
