“…Guerra‐Santos et al. () indicated that alkaline protease activity in midgut of O. niloticus showed a daily rhythm, and both the achrophase appeared at the beginning of the dark phase in both 1,100 and 2,300 groups. Paredes, López‐Olmeda, Martínez and Sánchez‐Vázquez () revealed that most genes about lipid metabolic gene expression in liver of zebra fish displayed a significant daily rhythm with an acrophase of expression in the dark phase, which showed a strong synchronization to the L/D cycle, feeding time barely influenced daily expression rhythms.…”

To better understand the molecular mechanisms underlying digestion and absorption in the intestine of the darkbarbel catfish (Pelteobagrus vachellii), we studied the intestinal transcriptome between day and night‐time. In this study, two triplicate groups of P. vachellii (1.05 ± 0.36 g) were fed either at 08:00 (D24 group), control) or 20:00 (W24 group) with the same amount of commercial feed. A significant increase of the apparent digestibility (AD) of protein and lipid was observed in the night group (p < 0.05). Comparison of gene expression levels revealed that 1,125 genes were significantly up‐regulated and 364 genes were significantly down‐regulated in the night group. Among them, 54 digestion‐ and absorption‐related genes, apolipoprotein A‐I, trypsin 1b, solute carrier family 26 member 6 b, sodium/glucose cotransporter 1, cholecystokinin B, maltase‐glucoamylase, diacylglycerol O‐acyltransferase 2, ATP‐binding cassette subfamily A member 1‐like and phospholipase A2, etc., were up‐regulated. Additionally, in the night group, 18 carbohydrate metabolism‐related genes, 17 protein metabolism‐related genes and 16 lipid metabolism‐related genes were up‐regulated, including fatty acid‐binding protein, diacylglycerol O‐acyltransferase 2, adipose triglyceride lipase, phospholipase A2, glucose phosphate isomerase, glycogen phosphorylase, arginase‐2, d‐amino‐acid oxidase, glutamate dehydrogenase, glycine n‐acyltransferase, tryptophan 2,3‐dioxygenase, kynureninase, cysteine dioxygenase type 1 and glycine dehydrogenase. The results indicated that a shift in feeding time from day to night may improve the digestion and absorption of proteins and lipids. Moreover, the amino acid metabolism, triglyceride synthesis, gluconeogenesis may be also influenced by the shifted feeding time.

“…Several fish species maintained under a periodic feeding regime have shown synchronization of their physiological rhythms to mealtimes (Montoya, López‐Olmeda, Yúfera, Sánchez‐Muros, & Sánchez‐Vázquez, ). In addition, some marine fish species have shown that digestive enzymes have daily rhythmic changes (Guerra‐Santos et al, ). In this study, for standardization, fish were sampled at the first mealtime (8:00).…”

Effect of feeding frequency on growth performance, blood metabolites, proximate composition and digestive enzymes of Lebranche mullet ( Mugil liza ) Juveniles

et al. 2020

This study verified the effects of feeding frequency on growth, blood metabolites, digestive enzyme activities (alkaline protease, acid protease, amylase and lipase) and proximate composition of Lebranche mullet juveniles. Fish with initial weight of 13.6 ± 0.7 g were distributed in twelve tanks and fed one, three, five and seven times per day to apparent satiation for 60 days. While the final weight of fish fed only once a day attained just 15.4 ± 0.7 g, those fed five or seven times per day reached 54.0 ± 12.1 and 55.9 ± 6.1 g respectively. The feed consumption also increased at high frequencies, but feed efficiency was higher (76.7 ± 11.7%) when mullets were fed three times per day. In general, increasing feeding frequencies also increased blood content of metabolites (total protein, glucose, triglycerides and cholesterol), possibly due to increased intake and absorption of nutrients. The response of digestive enzymes correlated with feeding efficiency, with higher activity in fish fed three or five times per day. Concerning whole-body proximate composition, no significant difference was observed in protein, but lipid content increased significantly with feed frequency. Based on growth performance and biochemical responses, we recommend feeding Lebranche mullet juveniles three to five times per day.

“…Close relationships between the intensive period for digestive physiology and the peak period for feeding activities have been reported in previous studies. For example, Guerra-Santos et al (2017) demonstrated synchronization of the diel feeding time and digestive enzyme rhythms in Oreochromis niloticus. Several studies of fish and marine invertebrates have suggested that secretion of digestive enzymes increased before the anticipated diel feeding peak in preparation for the upcoming feeding activity (Vera et al, 2007;Montoya et al, 2010;del Pozo et al, 2012;Sun et al, 2015).…”

Comparative Study of the Feeding Characteristics and Digestion Physiology of Haliotis discus hannai and Haliotis gigantea

et al. 2021

Abalone (Haliotis spp.) are typical nocturnal creatures but Haliotis discus hannai is bold and active in the nighttime whereas H. gigantea tends to be timid and inactive. In this study, we quantified and compared differences in movement, feeding, and digestive physiology between H. discus hannai and H. gigantea as well as the potential molecular mechanisms on the basis of video observations and expression levels of genes related to feeding regulation. The feeding behaviors of both species were characterized by significant circadian rhythms (P < 0.05). However, the distance moved and the cumulative duration of movement were 2.61 and 1.94 times higher, respectively, in H. discus hannai than in H. gigantea over the 24-h cycle. The cumulative duration of feeding by H. discus hannai was only 1.15 times that by H. gigantea, but the feeding time as a percentage of the cumulative duration of movement (FTP) was up to 94.6% for H. gigantea and only 56.0% for H. discus hannai. The peaks for α-amylase activity and NPF expression levels in both species as well as the peak OX2R expression level in H. gigantea occurred during 20:00–00:00 h. By contrast, the peaks for alginate lyase activity and NPYR expression levels in H. discus hannai occurred at 16:00 h, when the FTP was significantly higher for H. discus hannai than for H. gigantea. These initial findings quantify specific behavior parameters and thus provide a reference for the selection of appropriate feeding strategies and the proliferation of abalone via bottom sowing.
