ABSTRACT
The striped snakehead (Channa striata) stocks from three locations were determined using multivariate
morphometic analysis. Nine measured characters of traditional measurement and sixteen measured characters of
truss network measurement, in 115 samples were applied for morphometric comparison. Allometric transformation
method was used to remove size-dependent variation to minimize the error on the obtained data of shape. A
Stepwise discriminant analysis revealed morphometric variation among different geographical localities, especially
morphometric features of head. Stock identification using original and cross-validation tests showed high
proportion of correct classification of 78.3% and 75.3% of truss network analysis, and increased up to 85.0% and
83.3% in the combination of traditional and truss network analysis.
