“…Following acclimation to a lower temperature the rate at which myofibrils split ATP is increased in the red and white muscle of goldfish (Penney and Goldspink 1981) and other cyprinids . This adjustment in ATPase activity maintains locomotory ability at low environmental temperatures.…”

“…Goldfish and other Cyprinidae show an alteration in the thermal'stability and specific activity of the myofibrillar ATPase (Penney and Goldspink 1981;Heap et al 1985). In these species the enzyme from cold acclimated fish had a decreased Arrhenius activation energy (Ea) compared to the enzyme from warm acclimated fish (Johnston and Walesby 1977).…”

“…Salmon (Salmo salar) was the most resistant of the salmonid fish to high temperature: when acclimated to 20°C, tolerated temperatures up to 28°C (Fry, 1947after Brett, 1952. Salmonid fish choose a very low range of preferred temperatures independent of the acclimation temperature, whereas cyprinid fish showed a strictly defined temperature preference after 2 months of acclimation (Penney and Goldspink 1981). The reason for the decreased swimming speed in cold water is clear if one considers the acclimation temperature does not change the contraction time of muscle, that contraction rate decreases exponentially with temperature increases (Wardle, 1980).…”

“…However, in cyprinids which are more evolutionary advanced than stenothermal salmonids, the key enzyme in muscle contraction (miofibrillar ATP-ase) has a much higher specific activity in cold water than one would expect from Qto. This is due to regulatory proteins (Penney and Goldspink 1981). Even so, in cold water, carp recruits a greater number of fast, white fibres than it would recruit in warm water in order to achieve the same swimming speed (Rome et al 1984).…”

“…Intraspecific variation also occurs. Goldfish acclimated at temperatures between 5 and 35°C showed adaptation of the myofibrillar ATPase within the range 10-30°C (Penney & Goldspink, 1981~).…”
