Abstract
Gammarus aequicauda is a euryhaline amphipod that is a common inhabitant of brackish environments of theMediterranean Sea. In the Ebro delta, the population density of G. aequicauda is highly variable throughout the year. The main objective of this study is to investigate the effect of salinity on the growth of G. aequicauda juveniles. G. aequicauda embryos and juveniles can survive and grow in the laboratory between 2 psu and 40 psu salinity, depending on the previous acclimation period for the reproductive individuals. Adults acclimated at 34 psu produced embryos and juveniles that survived and developed at salinities between 9 psu and 40 psu; adults acclimated at 9 psu produced embryos and juveniles that could develop in oligohaline conditions. The lower growth rate values were 10.9 μmd−1 and 13.5 μmd−1 at 40 psu and 2 psu, respectively, with the higher values of 18.0 μmd−1 and 18.5 μmd−1 at 19 and 34 psu, respectively.
