Myanmar Name(s): none
This species of mahseer is easy to identify thanks to its dark lateral stripe starting behind the head and extending to the caudal-fin. However, it seems to often present important phenotypical variations depending on the characteristics of its surrounding biotope, resulting in darker or lighter colorations, a loss of that dark lateral stripe and sometimes blue colorations that give it its other name “the blue mahseer”.
Biology / Diet / Bahevior
Primarily a predator, this species of mahseer is actually very eclectic and opportunistic in its diet; it feeds on smaller fishes, both aquatic and terrestrial insects along as well as a variety of freshwater crustaceans. It is also knnown to feed on fruits. Gregarious by nature, they live in groups where individuals are usually similar in size.
Adults inhabit clear forested streams and rivers, enjoying swift flowing well-oxygenated water. They tend to disappear when human activities degrade aquatic habitats, as seen in other members of the genus. Mostly sedentary, some individuals have however been shown to migrate for a few kilometers up or down the river. Larger specimens apparently tend to frequent deep pools of main river channels, but also venture in shallow waters when undisturbed.
