The effects of temperature on muscle pH, adenylate and phosphogen concentrations in Oreochromis alcalicus grahami, a fish adapted to an alkaline hot-spring
(Wiley, 1983)
The concentrations of phosphorylcreatine (PCr), adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), inorganic phosphate (Pi), pyruvate and lactate were determined in freeze-clamped ...
Sodium balance in the catfish Clarias mossambicus exposed to acid water
(University of Nairobi, 1983-08)
African catfish, Clarias mossambicus showed no ill effects when kept in acid water pH 4–5 for 3–4 days. Their ionic regulatory response was examined and during 24 h exposure to water of pH 4, Na+ efflux increased significantly ...
Ionic content of body fluids and sodium efflux in Oreochromis alcalicus grahami, a fish living at temperatures above 30°C and in conditions of extreme alkalinity
(Elsevier, 1984)
1. Values for blood plasma ions at 35°C are: Na, 210.4 ± 4.6; Cl, 144.6 ± 2.6 and K, 6.5 ± 0.4 mM; osmotic pressure, 400 ± 18 mOsm.
