Abstract
This study aims to determine the growth pattern and maturity level of gonad cork fish living in Tukad Yeh Sungi and Subak Baru irrigation channel. This research uses observation method, descriptive and analytic method. Sampling method directly catch fish in the cork by using fishing gear then analytic and described. The samples counted 101 fish samples. Using analytical and descriptive data analysis techniques. The results of the study found the growth pattern of cork fish in negative alometric river while in the irrigation channel for the positive allometric female and the negative alometric male.The maturity level of gonad of cork fish seen directly from the surgical result is influenced by the weight and weight of the fish weight.
