Morphological variations between native and Vietnam-originated striped snakeheads (Channa striata) in Bangladesh

The freshwater striped snakehead, Channa striata, known as “shol” in Bangladesh was introduced from Vietnam for commercial aquaculture that lacks morphological background. Therefore, the present study sought to differentiate various C. striata populations morphologically using one hundred eighty-six samples, consisting of nine native and two Vietnam-originated Bangladesh. Seventeen morphometric six meristic characters were studied, analysis highlighted Vietnamese snakeheads significantly different considering all traits examined except eye diameter. discrimination illustrated pelvic fin length (PVFL), pectoral (PCFL), mouth gape (MG), body width (BW) central caused between populations. However, findings compared with previous reveal do not correspond wild morphotypes need maintain carefully avoid possible new through genetic introgression culture condition practiced
