Modelización estadística de la actividad de los pescadores de percebe de la costa asturiana, España

Abstract

The fishing behaviour of Cudillero fishermen were studied using logistic regression models for linking their fishing activities with oceanographic data. A general pattern of explicative variables was observed across all fishermen. Wave height and tide width were the selected variables that may explain better the catch behaviour of the fishermen. A differential response to this variables was also detected, while some fishermen were less susceptive to tide with and wave height than other. A seasonal pattern of variation in the response variables was also observed. Three groups of fishermen were detected. Some fishermen changed their susceptibility to this variables during the analyzed period, taking a more “risky” approach during the October-December period, but then changing it behaviour to a more “conservative” one for the January-April period. The second group presented a more stable behaviour during the whole analyzed period. The third group was characterized for going to fish only during the October-December period.
