Morphometric characters along with truss network measurements and meristic counts were applied. Measurements of body parts were made with the head of fish pointing left. Since meristic characters were independent of size of the fish and did not change during growth the raw meristic data were used in analysis. Significant differences were observed in four of 6 meristic counts and twelve of (1-11, 10-11, 2-10, 3-11, 4-5, 5-8, 5-6, 6-7, 6-8, 3-12, 10-12, 4-6) out of 30 truss measurements. The first DF accounted for 86.0% while the second DF accounted for 14.0 %, respectively explaining 100% of total variability. The cross validation of this analysis revealed that the percentage of correctly classified fishes was 80.7% into their original groups. . The analysis revealed that there is an intermixing of stock between the three populations of S. esocinus.
