STUDI KROMOSOM IKAN BAUNG (Hemibagrus lacustrinus NG & KOTTELAT, 2013) FAMILI BAGRIDAE DI MATUR, SUMATERA BARAT
ABSTRACT: Chromosomal
characteristics of catfish Hemibagrus lacustrinus, known as Baung fish, a new
species of bagrid catfish from the upriver stream of Batang Sianok, West
Sumatra, that recently described by Ng and Kottelat, 2013 was examined from the
gills of 5 healthy specimens using general squash method. The result showed
that diploid chromosome number of this species was 2n=56. The karyotype
consisted of 28 metacentric (m), 10 submetacentric (sm), 8 subtelocentric (st)
and 10 acrocentric (a) chromosomes. The chromosome formula can be represented
as 2n= 28m+ 10sm+ 8st+ 10a. The largest chromosome in this species is a pair of
submetacentric chromosomes and the smallest pair is acrocentric chromosomes.
The present study is the first report on the karyology of this particular
species and helping to support the karyotype data of the genus Hemibagrus. This
study will also open for several future studies to explore this species.
