TLDR
The normal blood glucose level of Channa punctatus undergoes a seasonal change, but a post-spawning hyperglycemia is found during August, September, October and November and does not appear to affect the blood glucose in this fish.Abstract:
The normal blood glucose level of Channa punctatus undergoes a seasonal change. A post-spawning hyperglycemia is found during August, September, October and November. Fish kept out of water show increase in blood glucose level upto 24 hours. When returned to water, the asphyxial hyperglycemia subsides after 24 hours. Starvation does not appear to affect the blood glucose in this fish.read more

Haematological characteristics of Clarias isheriensis Sydenham
TL;DR: Haematological characteristics of Clarias isheriensis, a freshwater teleost, were established as a ‘working document’ upon which to base more extensive studies and correlations were found with certain blood factors as functions of the physical parameters of length and weight.

Haematology and leucocyte enzyme cytochemistry of a threatened yellow catfish Horabagrus brachysoma (Gunther 1864)
G. Prasad,Sonia Charles +1 more
TL;DR: Results reveal the haematological make-up and effective immune mechanism of this threatened fish and show it to be highly adaptive in nature, and may be useful in programmes aiming the effective conservation of this species.

Serum cortisol, glucose and lipids in plaice (Pleuronectes platessa L.) exposed to starvation and aquarium stress.
Ann White,Thelma C. Fletcher +1 more
TL;DR: Serum cortisol and glucose showed a significant correlation over 15 days and were not apparently affected by starvation, and only cortisol provided a sensitive indicator of aquarium disturbance.

Observations on the blood physiology of five South African freshwater fish
TL;DR: Various parameters of the blood physiology of five South African species of fish have been investigated and results show that plasma and serum samples differ in electrophoretic pattern, and also in the number of fractions and the protein concentration of these fractions.

Sexual maturation in the black seabream Mylio macrocephalus Teleostei, Sparidae: changes in pituitary gonadotropes, hepatocytes and related biochemical constituents in liver and serum
TL;DR: The black seabream, Mylio macrocephalus, exhibits the phenomenon of sex segregation, and changes in pituitary gonadotropes and liver tissue studied by light, and electron microscopy, and seasonal changes in serum constituents were studied by biochemical techniques.

A photometric adaptation of the somogyi method for the determination of glucose
TL;DR: In this paper, the reliability of the various Somogyi-Shaffer-Hartmann (SHH) copper reagents for glucose determination in biological material has been established, which can be accomplished by omission of the iodide and iodate in their preparation, since these interfere with the molybdate color reagents.

Blood sugar and activity in fishes with notes on the action of insulin
I. E. Gray,F. G. Hall +1 more
TL;DR: The blood sugar of fishes is reduced by the action of insulin, and the normal sugar of some of the sluggish fishes is often lower than the insulin-reduced sugar of the more active fishes.

The Effect on the Blood Sugar of Fish of Various Conditions Including Removal of the Principal Islets (Isletectomy)
N. A. McCormick,J. J. R. Macleod +1 more
TL;DR: The degree of variability in the results does not seem to justify the conclusion that the sugar rises within a few minutes and then falls again during the asphyxial period, and the degree to which the blood sugar of different fishes of the same species may vary independently of such an operation.
