Pangasiidae (Shark catfishes)
Etymology: Pangasius: The Vietnamese name of a fish (Ref. 45335); kunyit: Kunyit is from the Javanese word for saffron referring to its goldfish color..
Environment: milieu / climate zone / depth range / distribution range
生态学
; 淡水; 半咸淡水 底中水层性.
Asia: major drainages from Sumatra, Indonesia (Musi, Batang Hari and Indragiri rivers); also present in eastern Kalimantan (Mahakam, Kapuas and Barito rivers), Sabah, Malaysia (Kinabatanagan River) and Viet Nam (Mekong delta).
大小 / 重量 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 70.2 cm SL (female)
背棘 (总数) : 2; 臀鳍软条: 30 - 33. Distinguished from all other Pangasius species by the combination of the following characters: a somewhat spatulated (broad and rounded) head (snout length 40.0-53.4% HL; head depth 48.0-54.7% HL; head width 70.7-76.6% HL); short palatine tooth plates (10.0-12.8% HL); a very robust dorsal spine (width of spine 9.25-11.2 times in its length).
Facultative air-breathing (Ref. 126274); Inhabits deeper waters. Occurs sympatrically with P. krempfi in the Mekong delta. It is considered as a candidate species for aquaculture and its reproduction in captivity has already been achieved in the Mekong delta, Viet Nam (Ref. 33567).
