“…Bottom salinity and river runoff have been considered the environmental variables with most impact on pre-recruit distribution and abundance on the Portuguese western coast . Gamito et al (2015) analysed 86 years of fisheries data in an area south of the Tejo and did not find a relationship between rainfall and O. vulgaris landings. However, a significant effect of SST was observed (Gamito et al 2015).…”

“…Ria de Aveiro is a shallow coastal lagoon system with large intertidal areas, where S. officinalis finds adequate conditions for spawning (Pereira et al 2009). The variable month was also included in the model, which would likely be explained by the seasonality of cuttlefish fisheries, which target S. officinalis spawners inside estuarine systems (Batista et al 2009;Gamito et al 2015). No relationship between river drainage and landings of S. officinalis was found.…”

“…Climate-induced changes in Portuguese fisheries have already been reported (Gamito et al 2013(Gamito et al , 2015Teixeira et al 2014). There has been a reduction in the intensity and frequency of rainfall in Portugal (IPCC 2007), which will also decrease the drainage of Portuguese rivers into coastal areas.…”

“…The Portuguese coast is mainly North-South oriented and is located in a biogeographic transition zone, between temperate and subtropical waters, a Corresponding author: rgamito@fc.ul.pt where several temperate and subtropical fish species have their southern or northern distribution limit (Briggs 1974). Ecological responses to recent climate change have been observed in Portuguese waters (Cabral et al 2001;Vinagre et al 2009) and the rising sea surface temperature in the region has been linked to fisheries landings (Gamito et al 2013(Gamito et al , 2015Teixeira et al 2014). A decrease in the intensity and frequency of rainfall has also been observed in Portugal (IPCC 2007).…”

-The Portuguese coast is particularly adequate for studies on the impact of climate change on fisheries, as it has faced an increase in both air and sea surface temperature and a decrease in intensity and frequency of rainfall. Ecological responses to climate change have already been observed in Portuguese waters, with consequences in fisheries. Regional climate models have predicted a further decrease in rainfall in Portugal by the end of the century, which will have a strong impact on the runoff into coastal areas. River drainage affects the physical, chemical and biological properties of coastal ecosystems, regulating habitat availability and favouring their productivity. The present study analysed the influence of river drainage on landings of coastal ports in the vicinity of four hydrologically distinct estuaries. Unlike previous results obtained for the Mediterranean, no significant relationships between river drainage and landings were found. Relationships between drainage and landings can be inconsistent among regions and dependent on how strongly a food web relies on nutrients and organic matter of river origin. In the Portuguese coast, an upwelling regime is of particular importance for the richness and diversity of the coastal ecosystem and for fisheries. The complexity of the coastal upwelling phenomenon together with a possible interaction of several other smaller scale factors acting on recruitment of commercial species may mask the effects of river drainage on landings. Nevertheless, as accentuated decreases in rainfall have been predicted for Portugal, the resulting reduction in river drainage may still strongly impact fisheries in the future.
