AbstractThe research project CONFLICT focuses in disentangling the potential socioeconomics, biological and ecological conflicts between the professional and recreational fishing in the NW Mediterranean. In this sense, the marine coastal resources have been exploited by artisanal fleet for ages. However, during the last decades, recreational fishing has become one of the main leisure activities and potential temporal and spatial conflicts between ones have appeared as consequence. Recent trends in fisheries assessment have demonstrated how these activities affected the population structures of targeted fish stocks, and indirect ecosystem effects have appeared at individual and populations levels. The project CONFLICT works simultaneously with scientists, managers and fishers with the final goal to establish the sustainable exploitation rates of the targeted species. One of the most important conflict species is Loligo vulgaris Lamarck, 1798. Therefore we would determine the population dynamics and exploitation of the species, by: 1) The characterization of the spatial-temporal distribution of the professional and recreational fishing efforts, 2), the determination of the annual fishing mortality and 3) the study of the biology and the population dynamics of this species. Methods include visual census to characterise the effort patterns, the evaluation of landing data recorded in Palma Wharf and experimental angling. As well as reproductive indexes and age and growth using daily growth increments in the statoliths. Moreover, the movement and behavioural patterns will be investigated combining conventional and acoustic tagging. All of this information will be explicitly included in individual-based population models, which will allow understanding the population dynamics based in the individual life-history behaviour, providing a useful tool for assessment and management.
