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

Glucose metabolism in fish: a review
TL;DR: The aim is to up-date carbohydrate metabolism in fish, placing it to the context of these new experimental tools and its relationship to dietary intake and it is suggested that new research directions ultimately will lead to a better understanding of these processes.

Carbohydrates in fish nutrition: digestion and absorption in postlarval stages
TL;DR: This review summarizes information regarding digestion and absorption of carbohydrates in cultivated fish and reports results of studies of digestive enzymes, e.g. amylase, chitinase, cellulase and brush border disaccharidases, which appear to be molecularly closely related and to have characteristics comparable to mammalian amylases.

Nutritional regulation of hepatic glucose metabolism in fish
TL;DR: Overall, data strongly suggest that the liver of most fish species is apparently capable of regulating glucose storage, and the persistent high level of endogenous glucose production independent of carbohydrate intake level may lead to a putative competition between exogenous glucose and endogenous glucose as the source of energy.

Utilisation of dietary carbohydrates in farmed fishes: New insights on influencing factors, biological limitations and future strategies
TL;DR: This review intends to put together pieces of the puzzle of dietary carbohydrate utilisation in fish based on new insights gained with respect to the various biological, nutritional and environmental factors influencing carbohydrate use, and promising future approaches to augment carbohydrate use in fish.

Protein and amino acid nutrition and metabolism in fish: current knowledge and future needs
Sadasivam Kaushik,Iban Seiliez +1 more
TL;DR: In fish, despite low muscle protein synthesis rates, the efficiency of protein deposition appears to be high, and research on specific signalling pathways involved in protein synthesis and degradation have been initiated to elucidate the reasons for high dietary protein/amino acid supply required and their utilization.

Induction of fatty acid synthase and S14 gene expression by glucose, xylitol and dihydroxyacetone in cultured rat hepatocytes is closely correlated with glucose 6-phosphate concentrations.
TL;DR: Gl glucose 6-phosphate is the most likely signal metabolite for the glucose-induced transcription of this group of genes and shows a clear-cut parallelism between its concentration and the degree of S14 and FAS gene expression.

Energy metabolism of swimming trout ( Salmo gairdneri )
TL;DR: The mobilization and oxidation rates of lactate, palmitate and leucine were particularly increased during swimming, indicating that protein is the major fuel, since glucose oxidation seems of minor importance.

The glycaemic index of foods containing sugars: comparison of foods with naturally-occurring v. added sugars*
TL;DR: It is concluded that most foods containing sugars do not have a high GI, and there is often no difference in responses between foods containing added sugars and those containing naturally-occurring sugars.

Species and tissue distribution of the regulatory protein of glucokinase.
A Vandercammen,E Van Schaftingen +1 more
TL;DR: The fact that there appears to be no situation in which glucokinase is expressed without regulatory protein is in agreement with the notion that the regulatory protein forms a functional entity with this enzyme.

Growth, lipogenesis and liver composition of juvenile white sturgeon fed different levels of D-glucose
TL;DR: Juvenile white sturgeon (Acipenser transmontanus) were fed different levels (0, 7, 14, 21, 28, 35) of dietary D-glucose for 8 weeks as mentioned in this paper.
