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

Effect of native and modified starches on nutritional and physiological performance of wild juveniles of red grouper (Epinephelus morio)
Ana Ruth Escoto Castillo,Leticia Callejas,Carlos Alfonso Álvarez-González,Carlos Eduardo Maldonado,Gerard Cuzon,Martha Gabriela Gaxiola-Cortés +5 more
TL;DR: In this paper, the authors evaluated the utilization of carbohydrates by wild red grouper Epinephelus morio and found that the best growth was obtained in fish fed cornstarch either native raw of waxycornstarch (p 0.05), whereas glycogen content increased up to 200 mg g -1 with waxy corn starch.

Culturing Crappies in Indoor Water Recirculating Aquaculture Systems
Gregory A. Dudenhoeffer,Charles E. Hicks,Russell Gerlach,Yongfang Zhang,Thomas R. Omara-Alwala +4 more
TL;DR: Performance was significantly affected by commercial feed, but survival and feed conversion ratio (FCR) were not, and an inverse relationship existed between density and growth variables except final biomass, which had a direct relationship with density.

Plant-energy sources for jundiá and carp juvenile
Viviani Corrêia,Leila Picolli da Silva,Fabio de Araújo Pedron,Rafael Lazzari,Cristiano Costenaro Ferreira,J. Radünz Neto +5 more
TL;DR: In this paper, the performance, metabolism and body composition of jundia (Rhamdia quelen) and common carp (Cyprinus carpio) juvenile fed with plant-energy sources were evaluated during 60 days.

PORTABLE POINT-OF-CARE DEVICE AS ALTERNATIVE TOOL FOR MONITORING BLOOD GLUCOSE IN LAMBARI Astyanax altiparanae: STRESS AND SEX-SPECIFIC EFFECTS
TL;DR: POC Accu-Chek Active® is an effective tool for glucose determination in lambari; there are sex-dependent differences in relation to blood glucose levels; the species is sensitive to stress transporting and glycemia is an immediate and appropriate physiological indicator.

Relação proteína:carboidrato no desempenho e no metabolismo de híbridos de Pseudoplatystoma fasciatum (fêmea) X Leiarius marmoratus (macho)
Seldon Almeida de Souza,R.C. Souza,D. F. B. Campeche,R. M. L. Campos,José Fernando Bibiano Melo +4 more
TL;DR: The 0.84 protein: carbohydrate ratio was recommended for the hybrid because it promoted better weight gain, smaller apparent feed conversion, great feed intake and largest daily specific growth rate.

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?”
