Domestic wastewater is a crucial source of contamination in freshwater ecosystems, with an estimated global production of 127.13 billion tons annually. Various sewage treatment facilities put in place for treatment of municipal wastewater generate sewage sludge, which accumulates contaminants from wastewater, posing risks to waterbodies upon discha...

Among larger species of fish found in Punatsang chhu, Brown trout (Salmo trutta) and Snow trout (Schizothorax richardsonii) are notable species. Snow trout is a native species, whereas Brown trout is an introduced species. Brown trout is noted to have a negative impact on the population of native species worldwide. This study studied the population...

Nemacheilids are freshwater fishes distributed mainly in the South–central regions of Bhutan and environmental variables seems to have significant effect on their distribution, abundance, and diversity. However, existing knowledge and information about nemacheilid’s association with its environment is limited in Bhutan. This study aimed to assess...

In Bhutan the Persian Walnut (Juglans regia L.) is highly valued for its timber and is listed under special class in Royalty on Forest Products of Bhutan. Possessing high timber and other medicinal values, the ecology of the species in the country was poorly understood. The study aimed to understand the ecological requirements and habitat modeling...

Cyprinidae (Teleostei: Cypriniformes) is the predominate family among Bhutan's freshwater fishes, yet significant gaps exist in the knowledge of their diversity and assemblage. Cyprinids were sampled from 54 plots across four river basins (Aiechhu, Jaldakachhu, Mangdechhu, and Punatsangchhu) using systematic sampling at an interval of 5 km. A total...

Luetshokha lake is noted to harbour invasive aquatic plants and experience reduction in water level. This research assessed the floristic and macroinvertebrate composition of Luetshokha lake in Samtengang, Wangdue and its potential to increase water level using rooftop rainwater harvesting (RWH). Presence of aquatic plants such as Brasenia schreber...
