Comparison of effects of temperature upon oxygen affinity in blood of brown, brook, and rainbow trout. three trout are quite similar, but with 10 mm. CCX tension significant differences are apparent. In the blood of several fish (Root, 1931; Willmer, 1934; Black, 1940), typical oxygen dissociation curves obtained in the absence of CO2 are shifted to the right by CO2. The shape of the curve may be altered as well as its position (Root, 1931), and one change in particular appears in the failure of the hemoglobin to become saturated with oxygen even at tensions of 150 mm. As a consequence of this situation the.
