Summary
The coastal fish assemblage of a sandy area adjacent to the Tagus estuary has been surveyed weekly from 2007 until 2018, based on catches of the beach seine fisheries operating in this area. Environmental parameters such as wind direction and strength, air and water temperature, moon phases, moment of the day (day/night), season, tidal height and distance to coastline were always registered. The main target species of this fishery are small pelagic fishes, such as sardine, mackerel and Atlantic horse mackerel, but more than 60 other species are regularly caught. Through the years several changes have been observed in the biomass of the target species and in the groups of species captured by this gear. In this work, we evaluate the impacts of climate change in the structure and functioning of this coastal assemblage. Sea surface temperature was analysed along the series. Years were classified as "hot" or "cold" taking into consideration mean values of SST along the series. Fish species richness and fish abundance for the most common species were compared between these two periods. Functional traits and ecological guilds were assigned to each species and the assemblage composition compared between warmer and cooler years. Monitor this fishing activity can help understand the variation of species assemblages in the study area through time and relate it with global changes and environmental parameters.
