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

Influence of High Carbohydrate Low Protein Diet on Growth, Apparent Digestibility and Hepatopancreatic Enzyme Activities in Fingerlings of Red Sea Bream Pagrus major
TL;DR: The influence of high carbohydrate low protein diets on growth, apparent digestibility and hepatopancreatic enzyme activities were investigated in red sea bream Pagrus major as discussed by the authors, showing that adding a large amount of carbohydrate to the diet cannot spare dietary protein without retarding the growth performance.

First feeding of grass carp (Ctenopharyngodon idellus) with a high-carbohydrate diet:the effect on glucose metabolism in juveniles
TL;DR: In this article, the authors investigated whether high-carbohydrate diet stimulus in the early larval stage of the grass carp (Ctenopharyngodon idellus) could affect glucose metabolism in subsequent life stages (i.e., the juvenile).

Rosiglitazone promotes glucose metabolism of GIFT tilapia based on the PI3K/Akt signaling pathway
TL;DR: In this article, the effects of rosiglitazone on glucose metabolism of GIFT tilapia based on the PI3K/Akt signaling pathway were explored and the results showed that a high-starchy diet supplemented with 10-20 mg/kg rosiglitazone had a better specific growth rate and protein efficiency.

Comparison of new and conventional processing methods for their effects on physical properties of fish feed
TL;DR: In this article, a high-moisture extrusion with a twin-screw extruder and a specially designed cooling die was developed to produce aquafeed that was soft in texture, durable, and extremely water-stable.

Insufficient or excessive dietary carbohydrates affect gut health through change in gut microbiota and regulation of gene expression of gut epithelial cells in grass carp (Ctenopharyngodon idella).
TL;DR: In this paper , the authors investigated the role played by gut microbiota and gut epithelial cells, and the gene expression profiles of the Gut Ecthelial cells in grass carp consuming diets with different carbohydrate levels.

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?”
