Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt): 9-10; Afterflossenweichstrahlen: 15 - 16; Wirbelzahl: 43 - 44. Immediately distinguished from T. smaragdinus by its much smaller head, more numerous scales (44-46 in lateral line series versus 36-39), and more numerous anal fin rays (151/2 - 161/2 versus 121/2 - 141/2). The very striking difference in size of the pharyngeal jaws of tonlesapensis, the linear dimensions of which are only about half as great as in T. smaragdinus, is much greater than would be expected if this difference were due only to the difference in head size, since the head is only about 20% longer in T. smaragdinus. Gill rakers on first gill arch 8.

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Found near the water surface. Highest numbers mainly in the tidal zone of large deltaic branches of the lower Mekong. Feeds on insect larvae. Sometimes seen in the markets, but usually used for making prahoc and tuk trey (Ref. 12693).
