The analysis of the absolute growth in seven body parts of crayfish (Cumbaroides similis Koelbel), such as carapace length, carapace width, abdominal length, abdominal width, sheliped length, second pereiopod length and third pereiopod length (the grolwth formula, y : a + bt ~ci applied) was performed. The results obtained are as follows: 1. The analyses of changing growth quantity for the seven body parts in both sexes showed concave shaped increase. 2. The largest ratios of the grourth quantity in both sexes were revealed in abdominal width (18.3677 times in male and 18.9253 times in female). 3. The srolwth rates of the seven body parts in both sexes showed a smooth increasing pattern. 4. 각B the sperifn'cgrouch rates revealed a decreasing pattern, moreover steep descendent patterns of it appeared in abdominal length of both sexes and abdominal width in male.
