TLDR
The focus then shifts to selected aspects of hormonal regulation of carbohydrate metabolism and dietary carbohydrates and their variable effects on glycogen and glucose turnover, and the correlation of dietary carbohydrates with fish health.Abstract:
The utilisation of dietary carbohydrates and their effects on fish metabolism are reviewed. Details on how dietary carbohydrates affect growth, feed utilisation and deposition of nutrients are discussed. Variations in plasma glucose concentrations emphasizing results from glucose tolerance tests, and the impact of adaptation diets are interpreted in the context of secondary carbohydrate metabolism. Our focus then shifts to selected aspects of hormonal regulation of carbohydrate metabolism and dietary carbohydrates and their variable effects on glycogen and glucose turnover. We analyse the interaction of carbohydrates with other nutrients, especially protein and protein sparing, and de novo synthesis of lipids, and finish by discussing the correlation of dietary carbohydrates with fish health.read more

Replacement of maize with graded levels of noodle waste in commercial diet of african catfish
TL;DR: A study was conducted to determine the suitability of noodle waste as maize replacement in the diet of African catfish juvenile, and the PCV peaked (P < 0.05) at the inclusion of the test ingredient and no pattern was observed in the cholesterol and triglycerides.

Oxygen consumption and ammonia excretion of black carp (Mylopharyngdon piceus Richardson) and allogynogenetic crucian carp (Carassius auratus gibelio ♀ × Cyprinus carpio ♂) fed different carbohydrate diets
TL;DR: The data indicate that the escalation of glucose to 40% in a fish diet results in high oxygen consumption and ammonia excretion in black carp, suggesting that the efficiency of glucose as an energy source for this fish is compromised by the high metabolic expenditure after feeding.

Regulation of glucose and lipid metabolism by insulin and glucagon in vivo and in vitro in common carp Cyprinus carpio L.
Xiao Yan,Chaobin Qin,Dapeng Deng,Guokun Yang,Junchang Feng,Ronghua Lu,Guiqin Wang,Guoxing Nie +7 more
TL;DR: This study demonstrates that insulin and glucagon possess the intrinsic ability to regulate hepatic energy metabolism in common carp, the regulation of which seems to be similar to that of the mammals at least at the molecular level.

Cortisol in teleosts: dynamics, mechanisms of action, and metabolic regulation
TL;DR: This review attempts to delineate common themes on the physiological and metabolic roles of cortisol in teleost fishes and to suggest new approaches that might overcome some of the inconsistencies on the role of this multifaceted hormone.

Stress responses and disease resistance in salmonid fish: Effects of chronic elevation of plasma cortisol
TL;DR: It is shown, by means of intraperitoneal implantation of cortisol, that chronic elevation of plasma cortisol levels in the brown trout results in a dose-dependent increase in mortality due to common bacterial and fungal diseases.

What if Minkowski had been ageusic? An alternative angle on diabetes.
TL;DR: It is suggested that the phenomena of insulin resistance and hyperglycemia might be more readily understood if viewed in the context of underlying abnormalities of lipid metabolism.

Pancreatic beta-cells are rendered glucose-competent by the insulinotropic hormone glucagon-like peptide-1(7-37)
TL;DR: It is reported here that GLP-1 confers glucose sensitivity to glucose-resistant p-cells, a phenomenon the authors term glucose competence, which is similar to membrane depolarization, the generation of action potentials, and Ca2+ influx, events that are known to trigger insulin secretion.

Glucose-6-phosphate dehydrogenase: a "housekeeping" enzyme subject to tissue-specific regulation by hormones, nutrients, and oxidant stress.
TL;DR: The central question of this review is “How can the G6PDH gene be constitutively expressed in some tissues while displaying adaptive regulation in others when there exists a single transcription unit for the gene?”
