Respiration of Fishes With Special Emphasis on Standard Oxygen Consumption: Ii. Influence of Weight and Temperature on Respiration of Several Species

Abstract

Standard oxygen consumption, as estimated by simultaneously measuring spontaneous activity and oxygen consumption, for five species of freshwater fishes, was measured in relation to weight and temperature. The fish studied were brown trout, Sulmo trutta; brook trout, Salvelinus fontinalis; common white sucker, Catostomus commersonii; brown bullhead, Ictalurus nebulosus; and carp, Cyprinus carpio. When expressed on a logarithmic grid, standard oxygen uptake increased linearly with weight for all species. The proportionate change in standard oxygen consumption for a given change in temperature appears to be independent of size within each species. The mean slope values of the regressions found for brown trout, brook trout, common white sucker, brown bullhead, and carp are 0.877, 1.052, 0.864, 0.925, and 0.894, respectively.The standard rates of oxygen consumption found in the present investigation are less in most cases than the lowest applicable values that could be found in the literature.Spontaneous activity, expressed in terms of average oxygen consumption over the standard rate, varied with temperature. Maximum spontaneous activity for a given species coincided roughly with its preferendum temperature.

Resting metabolism and heat increment of feeding in mandarin fish (Siniperca chuatsi) and Chinese snakehead (Channa argus)

“…In Pomadasys commersonnis (Du Preez et al, 1986) and S. meridionalis (Xie and Sun, 1990), the weight exponent in the standard metabolism -body weight relationship decreased with increasing temperature, whereas in Oreochromis niloticus, the weight exponent increased with increasing temperature (Ross and Ross, 1983). In other studies, the interaction between body weight and temperature had no significant effect on the rate of standard metabolism (Beamish, 1964;Degani and Gallagher, 1985). In the present study, there was a tendency for the weight exponent to decrease with increasing temperature (Fig.…”

At 25°C and 30°C, the rates of resting metabolism were similar for the two species.…”

“…The relationship between rate of standard metabolism (R s ) and body weight (W) of fish is often described by the power equation ln R s = a+ b ln W. Published b values range from 0.4 (Hoss, 1974;Pierce et al, 1981) to slightly above 1.0 (Beamish, 1964;Hoss, 1974). From the data for 69 individual teleosts, Clarke and Johnston (1999) calculated a mean b value of 0.79.…”

“…Generally, the rate of standard metabolism increases with increasing temperature, even though no universal mathematical description has been found for the standard metabolism-temperature relationship. Interactions between body weight and temperature on standard metabolism were studied in several species, but the results were inconsistent (Beamish, 1964;Beamish and Mookherjii, 1964;Ross and Ross, 1983;Degani and Gallagher, 1985;Eccles, 1985;Cui and Wootton, 1988;Xie and Sun, 1990). Heat increment of feeding is often expressed as a proportion of food energy, but data on this proportion covered a wide range from 3.4 -45.0% (Beamish and MacMahou, 1988;Xie and Sun, 1990;Kalarani and Davies, 1994), though most lay between 10 -20% (Beamish and MacMahou, 1988;Xie and Sun, 1990;Jobling, 1994).…”
