The effects of habitat temperature on the temperature dependence, Michaelis constants (Km), and maxim velocity(V_max)of myofibrillar Ca²⁺- and Mg²⁺-ATPase were experimentally studied using carps reared at 10°C(group L)and 30°C(group H)for different lengths of time. The tem-perature dependences of Mf Ca²⁺-and Mg²⁺-ATPase rose in both groups L and H with a longer rearing period, although the degree of increase differed for Mf Ca²⁺-and Mg²⁺-ATPase. The degree in Mf Ca²⁺-ATPase was larger in group L than in group H, while the degree in Mf Mg²⁺-ATPase was smalley in group L than in group H. Km values of both Mf Ca²⁺-and Mg²⁺-ATPase were smaller slightly in group L than in group H at reaction temperatures of 5°C to 30°C in the former, and 10 to 20°C in the latter. The Vmax level of Mf Ca²⁺-ATPase was higher in group L than in group H at 30°C, while the opposite was observed at 10°C. The Vmax level of Mf Mg²⁺-ATPase, however, was higher in group L than in group H at all reaction temperatures from 5°C to 30°C. We consider that these findings in Mf Mg²⁺-ATPase indicate the existence of an efficient mechanism for the production of energy in fishes living in low habitat temperatures.
