Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 3; Mjukstrålar i ryggfenan (totalt): 13-21; Taggstrålar i analfenan 3; Mjukstrålar i analfenan: 12 - 23. Body moderately slender, its depth about 19 to 23% of standard length; head short and narrow, interorbital width not more than 17.5% of standard length; belly sharply keeled, with 23 to 26 scutes. Pectoral fin tips pointed. Pterotic bulla absent. No notch at the center of the upper jaw. Last two anal fin rays enlarged.

Forms schools. Feeds on crustaceans (juveniles feed on copepods, rotifer eggs and plants). Breeds from May to October. The eggs are pelagic, developing rapidly before sinking to the bottom. Matures at 1 year, at 3.5 to 4.5 cm SL.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00871 (0.00365 - 0.02081), b=3.02 (2.81 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 2.9 ±0.34 se; based on food items.

Generation time: 0.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (tm=1; tmax=2).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Price category (Ref. 80766): Low.
