“…CCK is known to play a key role in the stimulation of pancreatic enzyme secretion, gallbladder contraction, intestinal peristalsis and delaying of gastric emptying in vertebrates including teleosts, and it is also involved in the control of food intake as a neuropeptide (Himick & Peter, 1994; Aldman & Holmgren, 1995; Einarsson et al ., 1997; Liddle, 1997; Volkoff et al ., 2005; Murashita et al ., 2008). Earlier studies have indicated differences in the timing of appearance and the distribution pattern of CCK‐producing cells in larvae with different gut morphology (Kamisaka et al ., 2001, 2002, 2003, 2005; Rønnestad et al ., 2007 a ). In species which have a straight gut at the onset of exogenous feeding, e.g .…”

One of the main gastrointestinal hormones, cholecystokinin (CCK), was studied in order to advance understanding of the control of the digestive process in Atlantic cod Gadus morhua larvae after onset of first feeding. Larvae were fed either natural zooplankton or enriched rotifers in similar rearing systems and sampled from hatching to 22 days post-hatch (dph). CCK was visualized by immunohistochemistry and the first CCK-immunoreactive (IR) cells were detected at 8 dph corresponding to 6 days after first feeding. The CCK-IR cells were mostly found in the anterior midgut, and the number of CCK-IR cells was lower in the posterior midgut. They were also present in the hindgut of some of the larvae, but not in the foregut. No clear differences were found in the ontogenetic appearance and the distribution pattern of CCK-IR cells between the two dietary treatments. This indicates that the onset of CCK production in the gut as well as the spatial distribution of the CCK-IR cells is not differentially affected by these diets. To what extent the hormone production itself is influenced by dietary factors needs to be studied by more sensitive methods.

“…In teleosts, CCK has been shown to retard gastric emptying (Olsson et al, 1999), regulate the secretion of pancreatic enzymes, stimulate gall bladder contractions in vitro and in vivo, and regulate intestinal peristalsis (Einarsson et al, 1997;Rajjo et al, 1988;Andrew and Young, 1988;Aldman et al, 1992). Most studies, however, have focused on the timing of CCK expression and its distribution pattern in early life stage, e.g., Paralichthys olivaceus, Hippoglossus hippoglossus, and Thunnus thynnus, whose CCK-producing cells are found only in the anterior midgut, or in the early life stages of teleosts (Kurokawa et al, 2000;Kamisaka et al, 2001Kamisaka et al, , 2002. In Plecoglossus altivelis, and Gadus morhua, CCKproducing cells are distributed as far as the posterior intestine (Jösson et al, 1987;Kamisaka et al, 2003).…”

Two feeding experiments were conducted to determine the effect of a 5 0 -inosine monophosphate (IMP)-supplemented casein peptide-based microdiet (MD) on the feeding activity, growth and survival of Pacific bluefin tuna (PBT) larvae. PBT larvae [total length: 14.0 mm (Exp. 1) or 13.3 mm (Exp. 2)] were fed a casein peptide-based MD supplemented with or without 3% IMP for 12 days. As a negative control, a limited number of yolk-sac larvae of spangled emperor Lethrinus nebulosus were fed only for the first 7 days and starved for the next 5 days. A sufficient amount of yolk-sac larvae of spangled emperor was fed in the Exp. 2. All fish in the control group had died by 9 or 10 days after the experiment. Extensive mortality was observed in fish fed the MD. The MD was only found in the stomach contents of PBT fed the MD ? IMP. Of the fish fed an IMP-supplemented diet, 50% survived for 12 days after the initiation of both feeding experiments. In addition, significantly higher growth than that observed during the first 7 days was seen in the PBT in the IMP treatment after 12 days of the feeding experiment. These results suggest that the supplementation of casein peptide-based MD with IMP could improve the feeding activity, survival and growth performance of PBT.
