The O2 carrying capacities of the hemo- cyanin in the hemolymphs were estimated at and mmol/l, respectively. Hemolymph ion concentra- tions were typical for a marine crustacean (Mangum, 1983a) and differed little among California, Hawaii, and brooding female G. ingens (Table I). Temperature/pH relationship in vivo The regression line calculated from //; vivo pH mea- surements versus experimental temperature (°C) is: pH = (T°C), r = , n = 35. The short term in vivo pH change due to temperature in the hemo- lymph of intermediate instar Gnathophausia ingens (ApH/AT = ) was similar to the change due to temperature in the neutral pH of water (ApH/AT , Reeves, 1977). This value is also similar to in vivo hemolymph pH changes measured in other crusta- ceans over physiological temperature ranges (McMahon and Burggren, 1981; Morris et ai. 1985, 1988; Morris and Bridges, 1989).
