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

Effects of dietary arachidonic acid and docosahexanoic acid at different carbohydrates levels on gilthead sea bream growth performance and intermediary metabolism
Rui Magalhães,N. F. Martins,F. Fontinha,Sara Moutinho,Rolf Erik Olsen,Helena Peres,Aires Oliva-Teles +6 more
TL;DR: In conclusion, few interactions between ARA or DHA and dietary digestible carbohydrates were found and at least in the presence of high ARA levels the n-3 LC-PUFA requirements were fulfilled with 0.5% EPA + DHA and gilthead sea bream tolerates well dietary inclusion of 20% starch.

Molecular cloning, expression and functional characterization of tumor necrosis factor (TNF) receptor-associated factor (TRAF)-interacting protein (TRIP) in grass carp, Ctenopharyngodon idella.
TL;DR: Results indicate that TRIP might play important roles in immune defense and has the potential to be used as a anti-inflammation target in grass carp.

Effect of fixed feeding time on growth, body composition, and hepatic histology of hybrid catfish (Pseudoplatystoma reticulatum x Leiarius marmoratus) fed with carbohydrates and lipids ratios
Martha Prieto-Guevara,Rodrigo Fortes da Silva,Leandro S Costa,Raquel Tatiane Pereira,Priscila Vieira Rosa +4 more
TL;DR: In this paper, the influence of feeding time and dietary starch and lipid levels on growth, body composition, and liver histology of hybridized Brazilian catfish was investigated using self-feeders.

Transcriptome analysis of the effect of high-temperature on nutrient metabolism in juvenile grass carp (Ctenopharyngodon idellus)
TL;DR: In this paper , two libraries were constructed from a high-temperature treatment group (T33) and a control group (t27) and sequenced using Illumina sequencing technology.

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?”
