Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; freshwater; brackish; pelagic-neritic; amphidromous; depth range 10 - ? m. Subtropical; 41°N - 14°S, 102°E - 140°E (Ref. 168)
Western Pacific: Akita, Honshu, Sea of Japan, Yellow Sea and China south to Vietnam and Cambodia where it enters the Mekong River.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 247 cm TL male/unsexed; (Ref. 83530); common length : 100.0 cm TL male/unsexed; (Ref. 27773); max. published weight: 131.00 g (Ref. 83530)
Dorsal spines (total): 15 - 17; Dorsal soft rays (total): 15 - 17; Anal spines: 0; Anal soft rays: 16 - 19; Vertebrae: 41 - 42. Interpelvic process small and bifid. Body covered with small scales. Lateral line abruptly curving down below first dorsal fin. Intestine with 2 folds and 3 limbs. Swim bladder present. Sides silvery with large round, indistinct spots in two poorly defined rows in adults. Juveniles with saddle-like blotches extending down to about middle of body.
Travels 300 km up the Mekong River, above Phnom Penh but believed to reproduce only in marine waters. Feeds on fishes and swims well upstream river because of easy food availability (Ref. 12693). No information on biology available (Ref. 9684). It is a prized food fish in Japan and probably in China as well. Utilized fresh, dried or salted and smoked; consumed pan-fried, broiled and baked (Ref. 9987).

Estimates based on models
Preferred temperature (Ref.
123201): 11.9 - 28.3, mean 26.6 °C (based on 719 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00392 - 0.01850), b=3.03 (2.86 - 3.20), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.5 ±0.80 se; based on food items.
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (90 of 100).
