Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 16 - 21; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 23 - 31.

Obligate air-breathing (Ref. 126274); Adults are generally found at sea, but young inhabit river mouths, inner bays, and mangrove forests. In freshwater, they occur in rivers, lagoons, lakes, and swampy backwaters (Ref. 2847, 44894). Tolerate a wide pH range (5.2-9.1) (Ref. 44894) and salinities from 0 to 100. Mainly diurnal (Ref. 7017). Predaceous, feeding mainly on fishes and crustaceans (Ref. 5213). Breed offshore, possibly throughout the year. Larvae are transparent and resemble larval eels (Ref. 13337), but with a forked tail (Ref. 167). Juveniles commonly enter freshwater (Ref. 44894, 48635) in clear or turbid water (Ref. 44894). Known to breath air, rising regularly to the surface to do so. Cultured in ponds, the fry being sourced from the coasts (Ref. 7050). Popular angling fish (Ref. 3969). Edible but not esteemed (Ref. 3969). Caught by gill nets, seines, and trawls, and by hook-and-line; marketed fresh and dried salted (Ref. 10982).

Estimates based on models

Preferred temperature (Ref. 115969): 19.8 - 27.6, mean 24.4 (based on 501 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00741 (0.00532 - 0.01033), b=3.07 (2.97 - 3.17), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.1 se; based on diet studies.

устойчивость к внешним воздействиям (Ref. 120179): средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Assuming tm<=4).

Prior r = 0.57, 95% CL = 0.37 - 0.85, Based on 2 data-limited stock assessments.

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Climate Vulnerability (Ref. 125649): High to very high vulnerability (75 of 100).

Категория цены (Ref. 80766): Low.
