“…According to this report, the endogenous rhythm throughout the day was independent of dietary treatment or short-term fasting, which is consistent with the results in sea bass (Galaviz et al, 2011). The negative feedback loop between CCK and trypsin has also been demonstrated in the development and experiment of Senegalese sole juveniles (Neda et al, 2021), Gadus morhua larvae (Tillner et al, 2013), and Clupea harengus L (Rojas-García et al, 2011). The uctuation of trypsin was not much different from that of CCK content, which may be because the hepatopancreas was in a rapid developmental stage, whereas CCK as a satiety factor responds quite quickly to hunger, resulting in negative feedback between the two without obvious synchronization, which was different from the cosine curve of Senegalese sole juveniles reported by Neda Gilannejad et al (Rojas-García et al, 2011).…”

“…The study found that CCK is involved in the endocrine regulation of the individual digestive process and that the uctuation rhythm in a single day was affected by feeding frequency and was not independent of feeding behavior (Rojas-García et al, 2011). A negative feedback loop between CCK and trypsin was observed in the daily rhythm test of juvenile Senegalese sole (Neda et al, 2021). The effects of fasting and feeding frequency on the digestive system of sh have been comprehensively reported, and our research group has also done a lot of research on fasting and re-feeding of M. pellegrini.…”

To study the regulation and feedback mechanism of cholecystokinin and trypsin in black bream, Megalobrama pellegrini (Tchang, 1930) 60 days after hatching under 15 days short-term fasting and different feeding frequencies within 24 hours during the same period, M. pellegrini (wet weight 183.75 ± 61.16 mg, total length 20.74 ± 4.08 mm) developed in a recirculating aquaculture system were selected as the subject. In the short-term fasting trial, the body weight, trypsin, and CCK of the feeding control group (FCG) were higher than those of the fasting test group (FTG). Trypsin and CCK in FTG reached the lowest value on the ninth day and the CCK content reached the highest value on the 11th day. A negative feedback regulation of CCK and trypsin had not been found in this trial. The degree of damage to intestinal chorionic epithelial cells was higher than that of hepatopancreas, and detachment of epithelial cells and the striatal border was the main damage. In the 24-hour daily rhythm experiment, juvenile fish were randomly assigned to (A) once feeding, (B) twice feeding, (C) three times feeding, (D) fasting. CCK showed a minimum value at 1:00+ in group A, while a peak occurred at night in group B\C\D and a maximum value in group C, and a single satiety stimulus can lead to increased hunger. The four treatment groups had an apparent closed-loop regulation while the control point of the fasting group (D) shifted forward to the next day. Different feeding frequencies in a single day had no direct effect on the long-term fluctuation of CCK and trypsin diurnal rhythm. Feeding three times a day was beneficial to the individual growth of juvenile M. pellegrini, a better growth results may be produced in the long term. This study aimed to provide a reference for the feeding strategy of juvenile M. pellegrini in the RAS.

“…Alternatively, the delay between maximum levels of gut CCK hormone (at the beginning of the light period) in larger Senegalese sole juveniles (∼67 g) under a single diurnal meal (P1) (Gilannejad et al, 2021b), and the cck expression peak (at 13:00 h) in our study, could imply the involvement of post-transcriptional and/or translational mechanisms. Besides gut content, a regulatory loop between CCK and trypsin has also been reported in Senegalese sole larvae and post-larvae (Navarro-Guillén et al, 2017) and larger juveniles (Gilannejad et al, 2021b). The existence of such regulation mechanism could not be confirmed in this study.…”

“…This inconsistency may indicate the difference between developmental stages addressed in these studies, suggesting a lack of a matured anorexigenic function of this hormone during early life stages (Bonacic et al, 2016). Alternatively, the delay between maximum levels of gut CCK hormone (at the beginning of the light period) in larger Senegalese sole juveniles (∼67 g) under a single diurnal meal (P1) (Gilannejad et al, 2021b), and the cck expression peak (at 13:00 h) in our study, could imply the involvement of post-transcriptional and/or translational mechanisms.

Understanding the daily digestive function could lead to more efficient feeding practices in the farmed fish species. In this work, the effect of several daily feeding protocols was assessed on the daily expression of the genes related to the circadian system (arntl1, clock, per1, and cry1), appetite (cck), nutrients hydrolysis (try1, ctrb1, pga, atp4a, cel, and amy2a), peptides transport (slc15a1), pH, and activity of key digestive (trypsin, chymotrypsin, amylase, 4C- and 7C-like lipases) and absorptive (alkaline phosphatase) enzymes in the gastrointestinal tract (GIT) of Senegalese sole (Solea senegalensis) juveniles. Some of the tested feeding protocols demonstrated a significant influence on the entrainment of the peripheral oscillator. The synchrony of slc15a1 and some digestive proenzymes with per1 in some of the experimental treatments could underline the role of clock genes in the regulation of these biological functions. Unlike gene expression of the digestive proenzymes wherein feeding protocol occasionally affected the temporal organization, the influence of this factor was determinant on the daily average production and/or circadian pattern of their activities. Daily pH was maintained at approximately neutral levels in all the GIT segments, and no pepsin activity was detected. Fish fed a single diurnal meal showed the lowest activity for all the studied enzymes, except for amylase, suggesting an insufficient utilization of the ingested nutrients. Higher amylase activity in this group, on the other hand, implies the possible activation of alternative compensatory metabolic pathways. Overall, our results pointed to the suitability of higher feeding frequencies, especially during dark hours, for the aquaculture production of this species.

“…Trypsin is one of the most important proteases in crustaceans (Aguiñaga-Cruz et al 2019). The activity of intestinal endopeptidases changes during feeding, and the fasting cycles are correlated with the amount of digesta in the intestine (Gilannejad et al 2021). Feed allocation must ful ll speci c conditions according to the daily average of digestive enzymes and their circadian pattern (Gilannejad et al 2021).…”

Feeding strategies have a significant impact on growth and water quality in shrimp farming. Feed management also affects health, survival, and shrimp yields. All these factors contribute to production cost-effectiveness and commercial shrimp industry sustainability. The effect of feeding frequency and two aquafeed cooking processes (extrusion and pelleting) on shrimp performance and water quality parameters were studied under controlled conditions in a 60-day trial with juvenile Litopenaeus vannamei fed once (10:00 h); twice (10:00 h, 12:00 h); four (10:00 h, 12:00 h, 15:00 h, 18:00 h); and six (10:00 h, 12:00 h, 15:00 h, 18:00 h, 21:00 h, 24:00 h) times/day. No statistical differences (p > 0.05) in growth rate, survival, nor feed efficiency were observed within pelleted feed treatments at any of the frequencies tested. Growth rate was significantly higher (p < 0.05) with extruded feed when administered once or twice in daylight (10:00–12:00 h). However, at such frequencies, growth was achieved at the cost of water quality and feed conversion ratio. At higher frequencies (six times a day) with extruded diets, the results in water quality suggest a reduction in total ammonia nitrogen and nitrite-nitrogen levels as frequency increased. The outcomes of this study suggest that extruded feed with daylight feeding has the potential to improve growth rate, and an increased frequency could represent a suitable strategy to preserve water quality. This study is the first to show that the extrusion process improves water quality; thus, extruded feeds could reduce effluent pollution impact and improve shrimp farming sustainability.
