Haemocyanin oxygen-affinity, measured in vitro on haemolymph samples drawn from hypoxic prawns, increased slightly during the first 3h of hypoxia acclimation (ΔP 50 =0.8-0.9 kPa at pH 7.6), returning to near normoxic control values after a 48 h hypoxic exposure. The respective roles of L-lactate and urate in...
