“…Sodium and chloride are much lower than in either cyclostome or elasmobranch muscle, approaching the values found in tetrapods, and occasional higher values (e.g. Becker et al 1958) probably represent contamination. The high sodium reported in the muscle of spawning salmon in fresh water (5'.…”

“…Despite the variety of environmental niches, teleosts maintain a relatively constant composition of the body in respect of water and electrolytes (Duval, 1925;Smith, 1930;Krogh, 1939;Forster & Berglund, 1953;Becker, Bird, Kelly, Schilling & Young, 1958;Koch, Evans & Bergström, 1959;Robertson, 1959;Sharratt, Chester Jones & Bellamy, 1964a). Many factors contribute to the maintenance of homeostasis, ranging from intrinsic properties of epithelia in relation to varying ionic concentrations (see Chester Jones Sodium, potassium and calcium of muscle and serum were determined by flame photometry (Zeiss PF 5) with appropriate measures to take account of interference. Magnesium was determined by atomic absorption spectrophotometry (Hilger and Watts, H700 instrument) ; chloride on an Aminco-Cotlove Chloride meter (American Instrument Co. Ltd.); serum phosphate by the method of Negrin (1964).…”

The distribution of water, electrolyte composition (Na, K, Ca, Mg, PO4, Cl) and extracellular fluid volume of eels (Anguilla anguilla L.) were investigated under different experimental conditions. Adrenalectomy of the freshwater eel was followed by an increase in body weight, a fall in the amount and concentration of sodium in serum and muscle and a shift of water into the cells. The concentration of serum potassium remained within the normal range. Adrenalectomy of the sea-water eel was followed by a decrease in body weight and an increase in the concentration of extra-and intracellular sodium. The concentration of serum calcium also increased, that of potassium remained within the normal range but the actual content diminished.Removal of the corpuscles of Stannius from the freshwater eel gave some effects similar to adrenalectomy. There was, however, no significant increase in body weight but the concentrations of serum potassium and calcium rose. Removal of the corpuscles from the sea-water eel brought about changes similar to, but less pronounced than those after adrenalectomy. The results of the injection of mammalian corticotrophin, cortisol, aldosterone and anti-aldosterone compounds are given. They are discussed in the light of the possible roles of the adrenal cortex and the corpuscles of Stannius in the maintenance of homeostasis of the eel in different environments.

“…The liver differs from muscle principally in the very low water content (due to an extraordinary high fat content) and in the much higher values for Na and Cl. Yound, 1958), perch (Lutz, 1970) and the rat (Widdowson and Dickerson, 1964), and this has been interpreted as indicating a common pattern of high intracellular values of Na and Cl for this tissue (Lutz, 1971). It seems likely that this generalization can be extended to the coelacanths.…”

The coelacanth Latimeria chalnmiiae occupies a unique position in the phylogenetic tree of the vertebrates as the only living representative of the crossopterygians, a group generally thought to lead from the ancestral bony fishes to the amphibians (Berg, 1958;Young, 1962; Romer, 1966). This, together with the fact that until 1939 the crossopterygians had been considered long extinct, dying out in the Cretaceous, accounts for the great interest shown in these "living fossils." However, in spite of an almost continual search since the end of the Second World War only two females and 30 males have been found to date, and there has been chemical analysis on only one specimen. On this fish, a large frozen male, Pickford and Grant (1967) analyzed the blood, Brown and Brown (1967) searched for the ornithine cycle enzymes and urea in the liver, and Cowgill, Hutchinson and Skinner (1968) looked at the mineral content of its hard and soft tissues. The offer to us by the Royal Scottish Museum of access to another specimen was therefore accepted with enthusiasm and it was thought worthwhile to confirm and perhaps extend the results on the first. As our fish was also frozen a small study was made to find the gross effect of prolonged freezing on the distribution of ions in a common fish (the freshwater perch) to help us interpret our data.
