AbstractCholecystokinin (CCK) is a peptide hormone that plays an important role in intestinal phase of the digestion process, by being involved in the regulation of pancreatic enzyme secretion among others (Rønnestad et al., 2017). Peptides and free amino acids in the chyme act as signals that initiate the release of CCK, which in turn causes the release of pancreatic digestive enzymes into the gut lumen. Daily fluctuations of CCK and trypsin activity has been addressed especially in fish larvae. However, daily interaction of this hormone with pancreatic enzymes in juvenile fish under different feeding schedules has been scarcely studied. Therefore, the aim of the present work was to evaluate the influence of different feeding protocols, in terms of timing and frequency, on daily rhythm of CCK hormone and two pancreatic enzymes in juveniles of Senegalese sole (Solea senegalensis).
