The volume densities /Vv(mt,f)/ and absolute volumes of mitochondria /v(mt)/ were determined in body trunk red muscle of 15 specimens of Oreochromis niloticus weighing 0.65-812.3 g. Vv(mt,f) had a volume of 0.284 +/- 0.012 (S.E.) and V(mt) a value of 0.551 +/- 0.202 (cm3) (S.E.). Both parameters had scaling values of -0.028 and 1.13, respectively, when related to body weight. These results show that there might not be much change in the oxidative metabolism of red muscle with development. The greater than unity value for the scaling value of V(mt) in relation to body weight is due to the high scaling value of body trunk red muscle (1.157) in relation to fish body weight /11/.
