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.

Carbohydrate in rainbow trout diets: Effects of the level and source of carbohydrate and the number of meals on growth and body composition
TL;DR: In this paper, the effects of meal frequency on growth, feed efficiency, and body composition of trout were compared, and it was concluded that increasing the number of meals had no discernible effect, the efficiency of 30% glucose diet being the same in the various groups.

Glucagon-like peptide 1 (7-36 amide) secretion in response to luminal sucrose from the upper and lower gut. A study using alpha-glucosidase inhibition (acarbose).
TL;DR: GLP-1 release appears to be influenced by indirect mechanisms (early response after sucrose) and by direct luminal contact with lower gut mucosal endocrine cells (late response with acarbose).

Change of blood sugar and plasma insulin levels of fishes in glucose tolerance test.
Masayuki Furuichi,Yasuo Yone +1 more
TL;DR: The fishes exhibited a similar pattern of change in plasma insulin levels after the administration of glucose, but the maximum level of plasma insulin and a ratio of the maximum plasma insulin level to the maximum blood sugar level were lowest in yellowtail, followed by red sea bream and carp in increasing order.

Contribution of digestible energy from carbohydrates and estimation of protein/energy requirements for growth of rainbow trout (Oncorhynchus mykiss)
J.D. Kim,Sadasivam Kaushik +1 more
TL;DR: Four diets having different digestible protein (DP) to digestible energy (DE) ratios were formulated to study the protein-sparing effect of DE from carbohydrates and to estimate the DE requirements for growth of rainbow trout.
