I mainly work on the application of molecular techniques to fisheries and aquaculture studies to investigate the population genetic structure and evaluate the current status of genetic variability of stocks in natural populations of fisheries resources and marine organisms. I research the authenticity of fishery products; methods in aquaculture; strategies to minimize by-catches, for a gradual elimination of discards and effects on the habitat of traditional fishing in European fisheries; the detection of pathogens affecting marine organisms in Marine Protected Areas of the Mediterranean Sea; and evaluation of the effects of habitat and protection on the behavior, condition and growth of coastal fishes.
