Description

This is a relatively large species. It can reach 1 m (3.3 ft) in length and 18 kg (40 lb) in weight.[3]

Distribution

Boesemania microlepis lives in Cambodia, Laos, Indonesia (Borneo and Sumatra), Malaysia, Vietnam and Thailand.[1] It is found in several rivers such as the Mekong, Chao Phraya River, Mae Klong, Nan River, Tha Chin River, and Bang Pakong River.[1]

Habitat and behaviour

This species appears to be sedentary. It prefers large, flowing rivers.[1][3] During the peak of the dry season, it spawns in deepwater pools. During this time, common to other croakers, it can be heard to make loud, continuous, croaking sounds.[3]

Diet

Boesemania microlepis eats mostly small fishes and crustaceans such as shrimps.[1][3]

Threats

Desired as food, and expensive in southern Laos and northeast Cambodia, this species has become increasingly threatened due to overfishing.[4] Despite this, it remains common in much of its range.[1]

gollark: Just add `\n` to the end of `local pattern = "\n?%-%-%[%[ SIGNATURE: (.-) %]%]%-%-"`.
gollark: It appears to not remove the newline after the signature comment.
gollark: Maybe it's some whitespace which isn't being stripped properly.
gollark: I could assimilate it into potatOS if it's good then.
gollark: So as of now all privileged execution files/debugging disks are directly signed with the potatOS DSK.
