The purpose of this research study was to examine the growth pattern of ecdysis freshwater crayfish, especially crayfish type Cherax quadricarinaus aged 76 days to 116 days. The descriptive method was used. The data was collected through a direct observation. The data that was obtained consisted of an analysis done using simple linier regression. Because the weight of the crayfish was divergent, the data material was divided into 3 groups as a way to obtain data that was more accurate. For group 1, we obtained a linear regression with an equation of Y = 6,00 + 2,600X. For group 2, we obtained a linear regression with an equation of Y = 8,500 + 2,300X. Group 3 obtained a linear regression with equation of Y = 9,100 + 2,500X. The result explained a positive correlation between ecdysis with number of days. During the experiment, the water quality was still in the range of optimum, the DO ranged from 6,5 - 7 mg/l, the temperature was between 24o C - 27°C, the pH was about 7,5 - 8 and the ammonia was still at the range of normal <0,5.
