ABSTRACT Gilthead seabream were equipped with intraperitoneal biologging tags to investigate cardiac responses hypoxia and warming, comparing when fish either swimming freely in a tank conspecifics or confined individual respirometers. After tag implantation under anaesthesia, heart rate (fH) required 60 h recover stable value holding tank. Subsequently, undisturbed control conditions (normoxia...

Water temperature variations affect fish growth and health, often leading to huge losses in production, especially during the cold season. To alleviate this constraint, farmers can use a water heating system driven by solar energy daytime. This action will cause drop night period, making it important understand physiological response of exposed resulting day/night oscillations. investigate scen...
