Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2010-01-22

Danio dangilla is assessed as Least Concern since it has a wide distribution. Although there is reduction in the population due to exploitation from nature for ornamental trade, it has been successfully bred in ICAR (Indian Council of Agricultural Research) research stations of Assam and Meghalaya. Fish farmers have also learnt the technique.  Trends in wild populations must be monitored and if the captive breeding does not sustain the ornamental trade, the species has to be reassessed.
