Calanoides carinatus sensu lato (s.l.) (Krøyer, 1848) is known to occur in the North and South Atlantic, Indian, and tropical western Pacific Oceans, and the Mediterranean Sea. In highly productive areas, this species may dominate the copepod biomass

The reproductive activity and the physiological state of the calanoid copepods Calanus helgolandicus and Calanoides carinatus were investigated off the coast of NW Spain during autumn to evaluate the effect of short food resources on both populations.

The seasonal reproductive dynamics of the calanoid copepods Calanus helgolandicus and Calanoides carinatus and the main driving factors that control their reproductive activity were evaluated through a three-year study performed at two shelf stations
