Abstract

Hopong, a small town in the Salween (Thanlwin) River Basin, Myanmar, is located 35 km northeast of Inle Lake, a famous ancient lake with numerous endemic fish species. We surveyed the fish fauna of a spring pond in Hopong in 2016, 2019 and 2020 and identified 25 species. Of these, seven, including Inlecyprisauropurpureus and Sawbwaresplendens, had been considered endemic to Inle Lake and at least three species were genetically unique. Eight were suspected or definite introduced species, including Oreochromisniloticus and Gambusiaaffinis. We were unable to identify a nemacheilid species of the genus Petruichthys, which would need a taxonomic examination. The Hopong area is being developed rapidly and, hence, it is crucial to conserve its native fish species and the freshwater ecosystems.

Keywords: Burma; Inlecyprisauropurpureus; Microrasborarubescens; Physoschisturabrunneana; Sawbwaresplendens; mitochondrial DNA (mtDNA).

The haplotype networks of five species groups (“species endemic to Inle Lake”) generated with the TCS algorithm, based on COI regions (640 bp). Each bar on a branch corresponds to a single nucleotide substitution. Small dots represent hypothetical haplotypes. A Inlecyprisauropurpureus obtained from Hopong and two other localities. B Microrasborarubescens obtained from Hopong and two other localities. The Heho specimens were obtained from a local market and their original locality is unknown. C Physoschisturabrunneana and P.rivulicola obtained from Hopong and two other localities. The Heho specimens were obtained from a local market and their original locality is unknown. D Sawbwaresplendens obtained from Hopong and Inle Lake. E Petruichthysbrevis obtained from Hopong and two other localities and Petruichthys sp. obtained from Hopong.
