Size / Weight / سن
بلوغ: Lm ? range ? - ? cm
Max length : 73.0 cm TL جنس نر / بدون خواص جنسي; (Ref. 5217); common length : 45.0 cm TL جنس نر / بدون خواص جنسي; (Ref. 5217)
خارهاي باله پشتي (کل) : 0; شعاع نرم باله پشتي (کل) : 0; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 38 - 46. Belly with 20 to 24 + 12 to 14, total 32 to 37 scutes. Lower jaw projecting; upper jaw with a toothed hypo-maxillary bone between hind tip of pre-maxilla and lower bulge of maxilla blade; lower gill rakers 23 to 31 (in fishes of 10 to 50 cm standard length, with the lower numbers in larger fishes). Pelvic fins with distinct axillary scale; anal fin origin under dorsal fin base.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Riverine, apparently not entering the sea, although presumably tolerating some salinity at river mouths. Not clearly distinguished from P. castelnaeana in the past, so that previous biological or fishery data may apply to either species. Flesh considered low quality (Ref. 5217). Seldom captured in the lower reaches of rivers (Ref. 27188).
