dc.description.abstractMeasurements of muscle dimensions that affect respiration in relation to body weight were carried out in a tilapia, Oreochromis niloticus. The fish used in all measurements weighed 0.65–812.3 g. The data were analysed with respect to body weight using logarithmic transformations (log Y=log a+blog W). The slopes (b) of the log/log regression lines for weight of body trunk red muscle, average cross-sectional area of muscle fibre, average number of capillaries in direct contact with a muscle fibre, average capillary contact length with a fibre as a fraction of average fibre circumference and number of capillaries mm2 of fibre cross-sectional area [NA(cƒ)] were 1.16, 0.221, 0.084, 0.015, and −0.137 respectively. These results show that there is an increase in muscle cross-sectional fibre area and number of capillaries in contact with muscle fibres whereas number of capillaries supplying a unit area of muscle fibre decreases during development. There is development of new capillaries with increase in cross-sectional area of red muscle fibres.en
