Abstract The present study aims to investigate the reproductive biology of small pelagic Sardinella aurita Valenciennes, 1847 in Canary Islands, enable its reliable assessment and advise on appropriate management measures for a fishing resource showing declining trend landings. Reproductive sexual patterns round sardinella were examined from monthly random samples commercial catches landed by a...

Small pelagic fish (SPF) species such as European sardine Sardina pilchardus , anchovy Engraulis encrasicolus round sardinella Sardinella aurita and sprat Sprattus sprattus play important ecological roles in the Mediterranean Sea marine ecosystem. However, changes SPF abundance biomass have recently been observed basin. Therefore, uncovering trophic importance of to their predators is key unrav...

It has previously been shown that at least one species of fish (the American shad) in the order clupeiforms (herrings, shads, and relatives) is able to detect sounds up to 180 kHz. However, it has not been clear whether other members of this order are also able to detect ultrasound. It is now demonstrated, using auditory brainstem response (ABR), that at least one additional species, the gulf m...
