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

Crescimento de juvenis de jundiá (Rhamdia quelen) com diferentes proporções de amilose:amilopectina na dieta
Fabio de Araújo Pedron,J. Radünz Neto,Leila Picolli da Silva,Giovani Taffarel Bergamin,Daniel Maschio,Suziane Ghedini Martinelli,M.A.L. Della-Flora,Corrêia +7 more
TL;DR: The growth and carcass traits of jundia after 60 days being fed with different amylose:amylopectin ratio in diet were evaluated and it is demonstrated that theJundia has the potential to use starchy sources consisting of up to 26%Amylose without altering the digestibility of nutrients and fat deposition.

Alanine alters the carbohydrate metabolism of rainbow trout: glucose flux and cell signaling
TL;DR: In this article, the effects of 4 1/h exogenous alanine infusion on glucose metabolism in rainbow trout were measured in vivo, and the results showed that alanines inhibited glucose Ra (from 13.2±2.5 to 7.3±1.6

Dissertation
Effect of extrusion on the nutritional value of peas (Pisum sativum), chickpeas (Cicer arietinum) and faba beans (Vicia faba) and inclusion in feeds for European seabass (Dicentrarchus labrax) and gilthead seabream (Sparus aurata)
TL;DR: Use of legumes in seabass and seabream diets resulted in an overall increase in gastrointestinal evacuation time and a delay in glucose load, and physical characteristics of the pellets were not negatively affected for any of the tested diets.

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?”
