Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 12 - 18; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 16 - 27. With 5 to 8 unkeeled pre-pelvic scutes, followed by an equally thin pelvic scute, all with slender ascending arms; no post-pelvic scutes. Snout pointed, lower jaw a little prominent, with barely visible teeth in each jaw; second supra-maxilla short, about half length of maxilla blade.

Occurs in estuaries, lagoons and as much as 10 km up rivers, presumably tolerating a wide range of salinity. Reported to feed exclusively on rotifers (Ref. 6028). Marketed fresh or dried salted.

Bayesian length-weight: a=0.00468 (0.00188 - 0.01164), b=3.03 (2.82 - 3.24), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.1 ±0.26 se; based on food items.

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

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