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

Utilization of raw and gelatinized starch by blunt snout bream Megalobrama amblycephala as evidenced by the glycolipid metabolism, glucose tolerance and mitochondrial function
Li Zhang,Wen-Bin Liu,Paul B. Brown,Chao Xu,Hua-Juan Shi,Xiaochuan Zheng,Ling Zhang,Chang He,Yang-Yang Huang,Xiang-Fei Li +9 more
TL;DR: It is suggested that high dietary inclusions of gelatinized starch could enhance the glucose transportation, glycolysis, lipogenesis, lipid deposition, glucose tolerance and mitochondrial function of blunt snout bream, while depress the gluconeogenesis and fatty acid oxidation.

Effect of High Dietary Carbohydrate on Growth, Serum Physiological Response, and Hepatic Heat Shock Protein 70 Expression of Wuchang Bream (Megalobrama amblycephala) at Two Temperatures
TL;DR: It is suggested that higher dietary carbohydrate impact growth performance, the nonspecific immune ability and hepatic antioxidant abilities of Wuchang bream at higher temperature.

Effects of lipoic acid on growth and biochemical responses of common carp fed with carbohydrate diets
Renato Santos,Sergiane Souza Caldas,Ednei Gilberto Primel,Marcelo Borges Tesser,José Maria Monserrat +4 more
TL;DR: It is indicated that LA modulates lipid, proteins and carbohydrate metabolism together with the well-known antioxidant effect, and shows to enhance starch utilization taking into account muscle cholesterol and triglyceride levels.

Red beet and betaine as ingredients in diets of rainbow trout (Oncorhynchus mykiss): effects on growth performance, nutrient retention and flesh quality.
Julia Pinedo-Gil,Ana Tomás-Vidal,Miguel Jover-Cerdá,Cristina Tomás-Almenar,Miguel Ángel Sanz-Calvo,Ana Belen Martin-Diana +5 more
TL;DR: After feeding the red beet and betaine, fish flesh showed lower water activity and better textural and colour properties than the control and also a dose-dependent effect on lipid oxidation was observed.

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?”
