%X The effects of temperature on growth of phyllosomas of the Japanese spiny lobster Panulirus japonicus were investigated. Phyllosomas were individually reared at four temperatures (20&#176;, 22&#176;, 24&#176; and 26&#176;C), and intermoult period and moult increment were monitored. The improved B&ecirc;lehr&aacute;dek&#8217;s equation, G = aLb (T&#8211;&#945;)c(&#946;&#8211;T)d, was used to describe the relationship between growth characters (G: intermoult period, moult increment or daily growth increment), body length (L) and temperature (T), with a and b being constants that change at 17&#183;8 mm body length, c and d being common constants for all sizes, and &#945; and &#946; being the conceptual biological lower and upper critical temperatures, which are variables with body length. The intermoult period increased and the moult increment decreased with decreasing temperature. However, a negative influence on both the intermoult period and the moult increment was observed at 26&#176;C for medium-sized and large phyllosomas. The largest daily growth increment was obtained at 26&#176;C up to 15&#183;0 mm body length, and then at 24&#176;C. This indicates that the optimum temperature for growth decreases from 26&#176; to 24&#176;C at 15&#183;0 mm body length. This optimum temperature for growth seemed to be optimal for survival.
