Description : The objective of the study was to test the theory that larger individuals are more sensitive to warm temperatures, proposed as a result of limitations in their capacity to provide oxygen for aerobic metabolic activites. The study was performed in four populations of fish, reared or wild (reared European seabass Dicentrarchus labrax, wild European seabass D.labrax, wild Gilthead seabream Sparus aurata, and reared Nile tilapia Oreochromis niloticus), using a critical thermal maximum for swimming (CTSmax) protocol.
Nile tilapia data :The Nile tilapia data is from from Blasco et al. (2022) freely available at Mendeley: doi:10.17632/npmchftsjf.1. Fish performed similar protocols as for seabass and seabream.
