Laboratory studies on the thrce‐spined stickleback provided predictive equations for the relationships between food consumption, faecal production and growth, and between respiration rate and body weight. These equations were used to estimate the energy income and expenditure at monthly intervals during the annual reproductive cycle of females of mean length from two populations. In winter only a small percentage of the energy income was invested in ovarian or somatic growth, and the latter was negative in some cases. Routine respiration and faecal losses accounted for a high proportion of the energy income. In spring a higher proportion of the energy income was partitioned into somatic and ovarian growth while routine respiration accounted for a smaller proportion of the energy income.
