The construction of a reservoir dam alters the environment within its basin, including composition fish community, biodiversity, and river ecosystem itself. This study was conducted in Sanbanxi Reservoir used eDNA metabarcoding technology comprising capture extraction, PCR amplification, sequencing database comparison analysis, other environmental DNA standardized analysis processes to characte...

Nostril structures are important characteristics for generic diagnosis in Nemacheilidae and Cobitidae. Based on phylogenetic analysis, we found that 10 genera within (Eonemachilus, Guinemachilus, Lefua, Micronemacheilus, Oreonectes, Paranemachilus, Protonemacheilus, Traccatichthys, Troglonectes, Yunnanilus) shared tube-shaped anterior nostrils formed a monophyletic group. Morphologically, the l...

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...

Lepidocephalichthys guntea is an intestinal air breathing fish and belonging to the family Cobitidae. It is frequently found in the muddy, low dissolved oxygen, hypoxic and hypercarbic condition. So the comparative study of the antibiotic resistance profile of bacterial isolates from the gut of intestinal air-breathing fish, L guntea and its habitatsmall river Lotchka, West Bengal, India was ex...

Here, we propose a simple and inexpensive method for fish sperm cryopreservation. Sperm samples of the loach Misgurnus anguillicaudatus (Teleostei: Cobitidae) were diluted 7-fold by an extender containing 63.5 mM NaCl, 114 mM KCl, 20 mM Tris and 10% methanol. The cryogenic straws were placed in three kinds of self-made tubes which diameter was changed by commercially available materials and the...

Abstract Sabanejewia is a member of the family Cobitidae found in Europe and Asia. In previous studies, S. balcanica , caucasica aurata caspia were reported from Turkey. Of these Kura-Aras Basin. We examined morphological characters molecular data specimens Turkish parts river system to determine their taxonomic status. no differences between Kura Aras rivers’ populations terms morphology, but ...
