Freshwater fish from the Putao and Myitkyina areas were collected in three ichthyofaunal surveys of the Mali Hka River and tributaries in and around Khakaborazi National Park and Hponkanrazi Wildlife Sanctuary, Kachin State, from 2014-2016. Tor yingjiangensis Chen et Yang 2004, Tor qiaojiensis Wu et al. 1977, Garra qiaojiensis Wu et al. 1977, Garra bispinosa Zhang 2005, and Schizothorax oligole...

Ossifications associated with the gill filaments of members of the Balitoridae and Cobitidae are described for the first time. Although gill-filament ossifications are common in teleosts, similar ossifications were not observed in other members of the order Cypriniformes. Their presence is interpreted as a shared and derived character uniting the families Balitoridae and Cobitidae as a monophyl...

The present study was conducted on the Kolar River, a tributary of Narmada River. fish diversity River in Sehore district Madhya Pradesh, Central India, is represented this view. It investigated from February 2021 to June 2022. vital source water for people who live nearby villages, primarily domestic use. In community, fishing living and food common practise. study's goal investigate River's q...

Despite their great diversity and biological importance, evolutionary relationships among the endemic clade of East Asian Cyprinidae remain ambiguous. Understanding the phylogenetic history of this group involves many challenges. For instance, ecomorphological convergence may confound morphology-based phylogenetic inferences, and previous molecular phylogenetic studies based on single genes hav...

We have examined phylogenetic relationships of suckers of tribe Moxostomatini (Cypriniformes, Catostomidae) using cytochrome-b and Growth Hormone gene intron sequences. Phylogenies were significantly different from recent estimates of relationships based primarily on morphology (Smith, 1992) and cytochrome-b sequences (Harris et al., 2002). Overall, there was little support for many basal nodes...

A new species of river loach, Schistura megalodon sp. nov., is described from the Irrawaddy basin in Yingjiang County, Dehong Autonomous Prefecture, Yunnan Province, China. The following combination of diagnostic characters serve to distinguish it from all other congeners in the given zoogeographical region: a large processus dentiformes in the upper jaw, a short pre-anus length of 65.4%-66.3% ...

Lepidocephalus has been assumed to include only two species and confined to peninsular Malaysia and Indonesia. However, based on records and collections reported herein, the genus contains five species and is most common in the Chao Phraya basin of Thailand. Large rivers seem to be the preferred habitat, and difficulty in collecting these rivers may account for the paucity of specimens in colle...

We examined the phylogenetic relationships among the major lineages of otophysan fishes (Cypriniformes, Characiformes, Siluroidei, and Gymnotoidei) using a combined analysis of molecular and morphological characters. The molecular characters comprised 160 phylogenetically informative sites from nuclear-encoded ribosomal RNA and 208 phylogenetically informative sites from the mitochondrial genes...
