“…Interestingly, the precocious maturation observed in females may have also contributed to their increased ability to use dietary carbohydrates via the PPP and the glycogenesis as E2 is known to lower the concentration of plasmatic somatostatin in rainbow trout (Holloway et al, 2000) stimulating glycogenolysis (Eilertson et al, 1991) and reducing PPP (Eilertson et al, 1991;Polakof et al, 2012).…”

Callet et al. Carbohydrate Utilization in Trout Broodstock shown that broodstock are able to use a diet containing digestible carbohydrates as high as 35% and can then grow and reproduce normally over an entire reproductive cycle for females and at least at the beginning of the cycle for males. These results are highly promising and suggest that dietary carbohydrates can at least partially replace proteins in broodstock aquafeed.

“…However the lack of comparative data with respect to the action of teleost SRIF in the experimental system used herein, precludes meaningful deductions with regard to the relative potencies of mammalian and teleosts SRIFs. It is interesting to note that Eilertson et al (1991) have demonstrated a role for sSRIF-25 in hepatic glycogenolysis in the rainbow trout 0. mykiss. These data are suggestive of a certain degree of species specificity with respect to the physiological actions of lower vertebrate SRIFs.…”

Porcine galanin, somatostatins (SRIF-25 and SRIF-28) and invariant SRIF-14, known to have inhibitory-stimulatory actions on growth hormone (GH) secretion in higher vertebrates, were tested for their ability to affect plasma GH levels in coho salmon. Peptides were administered by intraperitoneal injection of 10 or 100 ng g-' body weight. All three SRIFs decreased plasma GH concentrations, their activity following the order SRIF-14 > SRIF-28 > SRIF-25. Galanin and an anti-SRIF produced pronounced, although transient increases in plasma GH.

“…Somatostatin promotes glycogen breakdown and the release of glucose from liver to plasma (Eilertson, O’connor et al 1991). And it can also inhibit hormones secretion, including insulin (Sheridan, Plisetskaya et al 1987, Eilertson and Sheridan 1993, Very, Knutson et al 2001).…”

The present study comparatively analyzed the blood glucose and insulin concentration, the temporal and spatial expression of brain-gut peptides and the key enzymes of glycolysis and gluconeogenesis in Japanese flounder by intraperitoneal (IP) injection and oral (OR) administration of glucose. Samples were collected at 0, 1, 3, 5, 7, 9, 12, 24 and 48h after IP and OR, respectively. Results showed that the hyperglycemia lasted 5 hours and 21 hours in OR and IP group, respectively. The serum insulin concentration significantly decreased (1.58±0.21mIU/L) at 3h after IP glucose. However, it significantly increased at 3h (3.37±0.34mIU/L) after OR glucose. The gene expressions of prosomatostatin, neuropeptide Y, cholecystokinin precursor and orexin precursor in the brain showed different profiles between the OR and IP group. The OR not IP administration of glucose had significant effects on the gene expressions of preprovasoactive intestinal peptide, pituitary adenylate cyclase activating polypeptide and gastrin in the intestine. When the blood glucose concentration peaked in both IP and OR group, the glucokinase expression in liver was stimulated, but the expression of fructose-1,6-bisphosphatase was depressed. In conclusion, brain-gut peptides were confirmed in the present study. And the serum insulin and the brain-gut peptides have different responses between the IP and OR administration of glucose. A negative feedback mechanism in the insulin-regulated glucose homeostasis was suggested in Japanese flounder. Furthermore, this regulation could be conducted by activating PI3k-Akt, and then lead to the pathway downstream changes in glycolysis and gluconeogenesis.
