This study provides new data on chromosomal characteristics and DNA barcoding of three endemic loaches of Iran: spiny southern loach Cobitis linea (Heckel, 1847), Persian stream loach Oxynoemacheilus persa (Heckel, 1848) and Tongiorgi stream loach Oxynoemacheilus tongiorgii (Nalbant & Bianco, 1998). The chromosomes of these fishes were investigated by examining metaphase chromosome spreads obta...

The region of Balkans is often considered as an ichthyologic "hot spot", with a great number of species and high portion of endemics living in fresh waters in a relatively small area. The Adriatic watershed in Croatia and Herzegovina is inhabited by six spined loach species (genus Cobitis) whose extinction risk estimations were based solely on their extent of occurrence (and/or area of occupanc...

The fish diversity of Chimmony Wildlife Sanctuary in the Western Ghats Kerala was studied between January 2018 and December 2020. ichthyofauna comprised 40 species belonging to 11 Orders, 17 Families, 29 genera, which 35% are endemic region, two state Kerala. Cyprinids were most dominant family, represented by 19 three followed family Channidae (3 species) loaches Nemacheilidae species). Of spe...

Subterranean biodiversity in Europe is spectacularly rich, with the Western Balkans being home to about 400 cave species, representing the highest number of species per area worldwide [1]. Nonetheless, cave fishes, which are the most commonly found vertebrates in underground habitats [2], have not been described from Europe so far [3]. Here, we report the first European record of a cave fish po...

Bangladesh is a country of 1,47,570 km2 of mostly flat topography, but about 12 percent is hilly. The hilly areas are confined to the northeast and the southeastern parts of the country bordering India and Myanmar. Hill streams are highly variable and very important for the study and understanding of the aquatic biodiversity of Bangladesh. Hillstream ecosystems include a variety of habitats inc...
