Using a growth model based on moult number, the assimilated carbon budget was constructed for Themisto japonica growing from the specimens just released from the marsupium to mature adults at 1-15°C. As budget parameters, growth (<I>G</I>), metabolism (<I>Me</I>), moult (<I>Mo</I>), and reproduction (<I>Re</I>) were measured and assimilation (<I>A</I>) was estimated as the sum of these four parameters (<I>A</I>=<I>G</I>+<I>Me</I>+<I>Mo</I>+<I>Re</I>). The results of the lifetime budget indicated that among these parameters the greatest allocation of <I>A</I> was to <I>Me</I> (70-83%). Lifetime expenditure of carbon for Me was the least at 7°C, and <I>Me</I> increased with either increase or decrease of the temperature from 7°C. A female grown to full adult size at 7°C invested 16.6% for G, 70.2% for <I>Me</I>, 2.1% for <I>Mo</I>, and 11.1% for <I>Re</I> 0f total A. General features seen in the partition of A to G, <I>Me</I>, <I>Mo</I>, and <I>Re</I> for <I>T. japonica</I> are similar to those of other planktonic crustaceans being reported. Considering the profound effect of temperature on the assimilated carbon budget, practical problems in defining the representative habitat temperature for diel vertical migrators like <I>T. japonica</I> in the field are discussed.
