Environmental drivers influencing the abundance of round sardinella (Sardinella aurita) and European sprat (Sprattus sprattus) in different areas of the Mediterranean Sea

Data on Sardinella aurita (round sardinella) and Sprattus sprattus (European sprat) in the Mediterranean Sea are limited due to their scarce commercial interest, at least European countries. Yet, these two small pelagic fish, sitting opposite ends of thermal range, could be interesting sentinel species monitor effects climate change basin. Using International Acoustic Surveys (MEDIAS) – most extensive source information we analyzed biomass several geographical subareas central western relation satellite-derived environmental parameters. Our findings highlight that S. responded temperature, salinity, chlorophyll concentration sea level anomaly, depending GSA examined, whereas correlated significantly with salinity 6, 7, anomaly 17. These data widen our knowledge factors contribute ecology species. Further studies spatial distribution interactions other species, predators prey needed depict a more comprehensive scenario.
