MORPHOLOGICAL VARIATION BETWEEN HATCHERY AND WILD ANABAS TESTUDINEUS, BASED ON TRUSS NETWORK ANALYSIS

Abstract

Several body measurement methods used to identify stock have recently been criticized because of inherent biases and weaknesses. As an alternative, a new system of morphometric measurement called the truss network has been increasingly used for stock identification. Therefore, the morphometric differentiations between wild and captive populations of Anabas testudineus were carried out throughout this study using a truss network. Truss measurements based on anchored at ten homologous landmarks with 19 distances of 120 specimens were measured. Discriminant analysis was performed to investigate distinctions and patterns of morphological variations between wild and captive populations of Anabas testudineus. The findings support the use of the truss network to study the morphological variation among populations as it provides interesting perspectives for the study of biodiversity patterns.
