Dinamica e aspetti biologici della pesca artigianale del litorale di Barcellona (Spagna)

Abstract

[IT] Il presente studio è stato realizzato tra Ottobre 2002 e Dicembre 2003 presso l'Istitut de Ciències del Mar di Barcellona (Spagna), del Consejo Superior de Investigaciones Científicas, all'interno di un progetto che ha l'obiettivo di valutare l'impatto delle opere di ampliamento del Porto di Barcellona sulle risorse di pesca tradizionalmente sfruttate. In tale contesto, la presente ricerca svolge un'analisi dell'attivitá di pesca della flotta artigianale di Barcellona e delle sue risorse. La "piccola pesca" è una pesca multispecifica e comporta l'impiego di svariati attrezzi e metodi di cattura (artes), che in molti casi interagiscono tra loro nello sfruttamento di una stessa risorsa. Si caratterizza per una notevole variabilità nel corso dell'anno, che consiste nell'alternanza dei metodi di pesca, delle specie catturate e delle aree visitate. Le dinamiche di questa attività sono strettamente correlate a quelle spazio-temporali delle specie di interesse commerciale. Il progetto di ricerca portato a termine ha permesso di descrivere tali dinamiche, la cui comprensione potrà trovare applicazione a fini gestionali e permettere lo sviluppo sostenibile dell'attivitá di pesca artigianale, che da sempre rappresenta un settore di grande valore socio-economico in ambito mediterraneo.

[EN] Small-scale fishery is a very variable activity, with highly multispecific catches and multiple strategies, which in many cases interact in the exploitation of the same resource. A feature of this activity is the alternation of gears, target species and fishing grounds throughout the year. The dynamic pattern of fisheries is bounded up with spatio-temporal dynamics of the resource. The aim of this research, carried out between October 2002 and December 2003, is to identify the existing dynamics, to analyse biological aspects of some case study species and to determine the interactions among fisheries. During the sampled year, total catches showed low values compared to 1992-2003 statistics. Sampling was carried out on a quarterly basis using the main artisanal fishing gears of Barcelona harbour fleet (North-Western Mediterranean). A total of 121 hauls were analysed, comprising a total of 305 taxa. Cluster analysis of catch composition individualized each fishing gear, identified by target species which vary depending on season, depth and sediment. [...]
