We investigated left-right turning preferences of N=260 juvenile European sea bass (Dicentrarchus labrax) reared in either: ambient conditions; ocean acidification (OA) conditions; or reared in ambient conditions but tested in OA water. Groups of 10 individuals were observed alone in a circular tank and individuals’ left and right turning during free-swimming were quantified using trajectory data from video. We show that near future OA levels does not affect the number of turns made, or behavioural lateralization (turning preference), in juvenile D. labrax tested in groups.
