“…Senegalese sole appears to be strongly influenced by photoperiod; however daily metabolic rate rhythm, to our knowledge has not been reported. The data of the present study is in accordance with the idea that Senegalese sole is a nocturnal species, as clearly shown by spawning and melatonin rhythms (Bayarri et al, 2004;Oliveira et al, 2009;Vera et al, 2007).…”

“…This species is considered a nocturnal species, since in laboratorial conditions they showed a higher activity and plasma melatonin during the night (Bayarri et al, 2004). Although it is well known that oxygen consumption follows a light-dark rhythm (De la Gándara et al, 2002), the influence of feeding on this rhythm is not yet available in Senegalese sole, or in any flatfish.…”

Senegalese sole is known to be a species with pronounced nocturnal feeding behaviour. However, as for most fish species, there is a lack of knowledge concerning the influence of such biological rhythm on metabolic rate. The aim of this study was to determine whether individual variation in routine and fed metabolic rate was affected by daily light-dark rhythms in juveniles of Senegalese sole. The individual oxygen consumption measurements in Senegalese sole juveniles were determined by flow-through respirometry, at fasted conditions and after the fish were fed a single meal, the meal time started at 0930 h and fish fed ad libitum for 30 min. The measurements were made during 22 h, of which 8 h was in the light and 14 h in the dark, and started immediately after transfer to the respiratory chambers at 1100 h. The results suggest an influence of light-dark cycles in routine metabolism. It was observed that oxygen consumption increased during the dark phase in fasted fish (FAST) but was higher during the light phase in fed fish (FEED). However, when feed is provided during the light phase, juveniles are capable of shifting oxygen consumption rhythms to respond to the energetic demands of digestion and growth. These results suggest that routine metabolism varies according to the species natural habits as Senegalese sole is known to be nocturnal. The findings of this study underline the importance of understanding the biological rhythms of the species under study before metabolic data are interpreted.

“…Plasma melatonin levels in the Senegalese sole Solea senegalensis showed typical daily rhythms consisting of low levels during photophase and high levels during scotophase (Bayarri et al 2004). For tench Tinca tinca identified the circadian secretion of melatonin under continuous dark conditions as well as light and dark conditions (Oliveira et al 2009).…”

Somatostatin (SS) and growth hormone-releasing hormone (GHRH) are primary factors regulating growth hormone (GH) secretion in the pituitary. To date, it remains unknown how this rhythm is controlled endogenously, although there must be coordination of circadian manners. Melatonin was the main regulator in biological rhythms, and its secretion has fluctuation by photic information. But relationship between melatonin and growth-related genes (ghrh and ss) is unclear. We investigated circadian rhythms of melatonin secretion, ghrh and ss expressions, and correlation between melatonin with growth-related genes in tiger puffer Takifugu rubripes. The melatonin secretion showed nocturnal rhythms under light and dark (LD) conditions. In constant light (LL) condition, melatonin secretion has similar patterns with LD conditions. ss1 mRNA was high during scotophase under LD conditions. But ss1 rhythms disappeared in LL conditions. Ghrh appeared opposite expression compared with melatonin levels or ss1 expression under LD and LL. In the results of the melatonin injection, ghrh and ss1 showed no significant expression compared with control groups. These results suggested that melatonin and growthrelated genes have daily or circadian rhythms in the tiger puffer. Further, we need to know mechanisms of each ss and ghrh gene regulation.

“…It often penetrates estuarine waters to feed (Cabral, ) at higher salinities but the olfactory system is able to adapt to lower environmental [Na 2000), although it cannot survive in full freshwater. As it is nocturnal and its main prey live buried in the substrate (Bayarri et al, 2004;Cabral, 2000), it is likely that olfaction plays an important role in food-search. Previous work has shown that the amino acids L-phenylalanine and glycine are released by one of the sole's main prey and that the sole has olfactory sensitivity to both (Velez et al, 2005;Velez et al, 2007b).…”
