Cytogenetic Study of Burnt-Tailed Barb (Balantiocheilos melanopterus) from Buriram Province

Abstract

Cytogenetic was studied of Burnt-Tailed Barb (Balantiocheilos melanopterus) using examples from ornamental fish shops in Buriram Province. The mitotic chromosomes were directly prepared from kidney cells and stained by conventional staining technique. The results showed that the diploid chromosome number of 2n=50 and the fundamental number (NF) was 76. The karyotype was composed of four large metacentric, four medium submetacentric, six large submetacentric, ten large acrocentric, two medium acrocentric, eight large telocentric, fourteen medium telocentric and two small telocentric chromosomes and no differences were found between sex chromosomes in both males and females.

The karyotype formulae could be 2n (50) = L^m₄ + L^sm₆ + L^a₁₀ +L^t₈+  M^m₄ + M^a₂ + M^t₁₄ + S^t₂.
