Standardized catch rate of albacore (Thunnus alalunga Bonnaterre, 1788) caught by the Spanish surface longline fishery in the western Mediterranean 2004-2015

| Resumo: | Standardized relative abundance indices of albacore (Thunnus alalunga Bonnaterre, 1788) caught by the Spanish surface longline, LLALB, in the western Mediterranean Sea were estimated for the period 2004-2015. Standardized CPUEs were estimated through a General Linear Modeling (GLM) approach under a negative binomial error distribution assumption. The main factors in the standardization analysis were fishing area and time of the year. Following a relatively stable trend for the period 2004-2008 and an increase between 2009 and 2010, the index seems to have declined since 2011 onwards. |
