Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 15 - 16; Spine anali: 0; Raggi anali molli: 12 - 23. Belly sharply keeled. No distinct silver stripe along the flank and the first (anterior) supra-maxilla minute or absent (cf. Platanichthys platana). Distinguished from very similar R. arcuata of coastal waters by having fewer dorsal and pectoral fin rays and fewer gill rakers total; from small Sardinella and Harengula by the evenly rounded hind margin of the gill opening.

Apparently confined to freshwater at mouths of rivers and their lower reaches. Presumably schooling.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00339 - 0.01349), b=3.13 (2.95 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.1 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Low.
