Twenty-three morphometric characters of samples were measured. The fork length of individuals which were caught (TL) were between 6.20 and 10.40 cm, and their weight (W) were ranged between 1.70 and 7.20 g. The effect of Artificial Neural Networks was investigated in predicting the statistical of fishery industry. The present study provides the first information on the biometric properties of Atherina boyeri in íznik Lake by Artificial Neural Networks.
