We characterized the 4.8 Mbp genome of Escherichia coli H1G2, a B1 lineage isolated from the gut of Bangladesh's national fish, Hilsa (Tenualosa ilisha). The complete assembly reveals specialized genes for sugar metabolism and adhesion, facilitating niche-specific colonization, thereby providing insights into the microbial ecology of this commercially significant species' gastrointestinal tract.
