“…In contrast, the nutrient efficiency of nonrestricted feeding strategies (auto-demand feeders) is usually higher, as fish are able to regulate their feed intake according to their appetite (Azzaydi et al 1998). Pedrosa et al (2019) reported decreased TAN excretion as a result, compared to manual feeding strategies. In our experiment, probably the increased total TAN excretion is caused by the increased feed intake that took place in that stage of the trial, but when feed intake is considered (Fig.…”

“…These rhythmic variations synchronize the animal with the environment and provide adaptive advantages by anticipating periodic events and programming physiological responses to occur at specific times of the day or year, thus increasing the probability of success and minimizing energy demand (Gerkema, 1992; Aranda et al, 1999). In addition, knowledge of biological rhythms has applications in the context of aquaculture (Parker, 1984; Mattos et al, 2017), fish physiology (Yufera et al, 2014; Cowan et al, 2017), behaviour (Montoya et al, 2010; Mattos et al, 2016), stress responses (Almeida et al, 2018; Tian et al, 2019), immune system (Bowden, 2008) and the productive performance of fish (Sánchez‐Vázquez et al, 1995; Pedrosa et al, 2019).…”

“…The effects of FF on intestinal function and health have not yet been well-explored in gilthead seabream, and only scarce and diverse results are available for other fish species. For instance, in Nile tilapia (Oreochromis niloticus) and arapaima juveniles (Arapaima gigas), changes in FF did not affect the activities of digestive enzymes [17,18], while in Lebranche mullet (Mugil liza) and white seabream (Diplodus sargus) juveniles, FF affected some digestive enzyme activities [19,20]. Dolly Varden char (Salvelinus malma) juveniles fed increasing FF (up to 6 meals per day) presented higher serum malondialdehyde (MDA, usually used as a marker of lipid peroxidation) content [21], while blunt snout bream (Megalobrama amblycephala) juveniles fed 3 or 4 meals per day presented lower liver MDA content in comparison with those fed with lower (1 or 2) or higher (5 or 6) meals per day [22].…”
