Using acoustic telemetry to locate flatfish spawning areas: Estuarine migrations of turbot Scophthalmus maximus and European flounder Platichthys flesus
Estuaries are complex environments, which provide important nursery areas for several fish species, but anthropogenic activities as well as low salinities may affect fish reproductive potential. This study investigated spawning migrations of turbot ( Scophthalmus maximus ) and European flounder ( Pl...
