...Jodie L. Rummer; Mani Roshan-Moniri; Shannon K. Balfry; Colin J. Brauner SUMMARY Like most teleosts, sablefish ( Anoplopoma fimbria Pallas 1814) blood exhibits a moderate Root effect (~35% maximal desaturation), where a reduction in blood pH dramatically reduces O 2 carrying capacity, a mechanism...

... secretion first evolved in the eyes of fishes, presumably for improved oxygen supply to an avascular, metabolically active retina. Evolution of this system was facilitated by prior changes in the pH dependence of oxygen-binding characteristics of haemoglobin (the Root effect) and in the specific buffer...

... at exhaustion in trout. The current study found no evidence that teleost haemoglobins with a Root effect cause extremely elevated O 2 tensions in aerobic tissues. Under normoxic conditions, P rm O 2 was significantly lower than arterial P O 2 (119±5 mmHg), and remained lower when the arterial to tissue P O 2...

...Bernd Pelster; Roy E. Weber ABSTRACT The influence of organic phosphates on the reduction in oxygen-carrying capacity at low pH (Root effect) in multiple fish haemoglobins has been analysed spectrophotometrically. In stripped haemolysates of carp, trout and eel, the Root effect in the presence...
