Impacto de los aportes fluviales sobre la productividad de la población de anchoa del sur de Cataluña

Abstract

En el III Congreso Ibérico se presentó una ponencia sobre el impacto de los aportes del Ebro sobre la población de anchoa de la región. Se utilizó un modelo de series temporales Box-Jenkins que analizaba los caudales en época de reproducción y las capturas de anchoa con datos de 1991 a 2001, y se observó una dependencia significativa de éstas con los caudales del año anterior. Actualmente, con 9 años más de información, obtenemos una mayor dependencia. Ello en parte se debe a la caída de capturas de mediados de la última década, por sobrepesca unida a bajos caudales, que casi lleva la especie al colapso en la zona. No obstante, y a pesar de la ausencia de nuevas medidas de protección, el aumento de caudales en los últimos tres años ha favorecido un cierto incremento de capturas, aunque sin evidente recuperación de biomasa
