Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 13 - 14; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 34 - 44; позвонки: 43 - 45. Diagnosis: Body compressed, belly with 16-19 pre-pelvic and 8-12 post-pelvic scutes, a total of 24-30 keeled scutes from isthmus to anus; maxilla long, reaching beyond base of first pectoral finray; first supra-maxilla a minute oval; lower gillrakers 18-24, the serrae on the inner edge in distinct clumps in larger fishes; anal fin with 3-4 unbranched rays and 31-40 branched rays; a dark blotch behind upper part of gill opening; inside of gill cavity bright orange (Ref. 189). This species overlaps the range of different other species of Thryssa, of which five have a similar maxilla, very small first supra-maxilla and overlapping gillraker counts; however of these five species, T. gautamiensis, T. malabarica, T. purava and T. whiteheadi all have the tip of the snout at or above the level of the centre of the eye, and the last two, plus T. stenosoma, have at least 38 branched anal finrays (Ref. 189).

A coastal, pelagic species (Ref. 28), apparently common along shore and in estuaries (Ref. 5430). Presumably schooling, occurring inshore and entering estuaries and lagoons, perhaps used as nursery areas, but moving further out in rainy seasons when coastal waters are freshened up by rivers (Ref. 189). It feeds on plankton organisms (Ref. 28). May be caught using ringnets (Ref. 5213). Generally marketed fresh, may be salted or dried (Ref. 5284).

Estimates based on models

Preferred temperature (Ref. 115969): 24.6 - 29.3, mean 27.4 (based on 294 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00513 (0.00307 - 0.00858), b=3.15 (3.01 - 3.29), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

устойчивость к внешним воздействиям (Ref. 120179): высокий, минимальное время удвоения популяции до 15 месяцев (K=0.5).

Fishing Vulnerability (Ref. 59153): Low vulnerability (24 of 100).

Категория цены (Ref. 80766): Medium.
