The complete mitochondrial genome of Pabdah catfish, Ompok pabda (Hamilton, 1822) was determined by MiSeq platform. The genome was 16,512 bp in length, in which canonical 13 proteincoding genes, 22 tRNAs, 2 rRNAs, and a control region (D-Loop) were encoded. The overall A þ T (55.10%) content was higher than G þ C (44.90%). Total nine genes were located at the L strand, and remaining 28 genes were at the H strand. The start codon of 12 protein-coding genes was ATG, except for COX1 (GTG). Incomplete stop codon (TAÀ/T-) was identified in six genes including COXII, COXIII, ND2, ND3, ND4, and Cytb. The mitogenome of O. pabda showed highest sequence identity with O. bimaculatus (86%).

The complete mitochondrial genome in Mola carplet, Amblypharyngodon mola (Hamilton, 1822) was determined by MiSeq platform for the first time in the genus. The mitogenome of A. mola was circular and 16,545 bp in length, which harbours a canonical 13 protein-coding genes, 22 tRNAs, 2 rRNAs, and a control region (D-Loop). Twenty eight genes were encoded on the H strand and the other 9 genes were on the L strand. The incomplete stop codon (TA-/T-) was identified in seven genes (COX2, COX3, ND2, ND3, ND4, ATP6, and Cytb). The mitogenome of A. mola showed highest (82%) sequence identity with Rasbora vaterifloris (GenBank No. NC015531), which is endemic to Sri Lanka.

The first complete mitochondrial genome sequence of Ailia coila from Bangladesh was determined by the bioinformatic assembly of the next generation sequencing (NGS) reads. The constructed circular mitogenome for A. coila was 16,565 bp in length which harbored the canonical 13 protein-coding genes, 22 tRNAs, 2 rRNAs. Two non-coding regions, control region, D-loop (927 bp), and origin of light strand replication, O L (30 bp) were also well conserved in the mitogenome. Among the currently reported mitochondrial genomes in the order Siluriformes, A. coila was most closely related to Eutropiichthys vacha (AB919123) with 85.63% sequence identity.
