Abstract

Vermiculated spinefoot, Siganus vermiculatus is one of the fastest growing and commercially important siganid species occurring in Indian waters. Stock discrimination of vermiculated spinefoot was carried out along the south Konkan coast of Maharashtra by using truss morphometry. The present investigation was based on a study of 66 individuals collected from Harnai, Ratnagiri and Malvan locations of the South Konkan coast of Maharashtra. A 14-point truss network with 26 truss variables was studied. Truss morphometry showed significant differences in II (4-5), MM (5-6), NN (5-10), OO (5-11), SS (6-10), TT (6-11), XX (10-11), YY (11-12) and ZZ (12-14) distances from the three sampling locations in 26 truss morphometric measurements thereby indicating phenotypic heterogeneity among populations of Siganus vermiculatus from the south Konkan coast at a small spatial resolution.
