Short description Morfologia | Morfometria

Raggi dorsali molli (totale): 10-13; Raggi anali molli: 11 - 13. Body deep and compressed; caudal peduncle tapering to narrow; caudal fin large; lateral line strongly decurved; head small, compressed, mouth terminal (slightly upturned); dorsal-fin origin behind pelvic-fin origin; scales on lateral line 54-62; dorsal fin with 10-13 rays; anal fin with 11-13 rays; pharyngeal teeth 0,5-4,0 or 0,5-5,0; brown-yellow above, scales on back and silver side darkly outlined (crosshatched pattern on small individuals); fins dusky; and small specimens with black caudal spot (Ref. 86798).

Occurs in lakes, ponds, sloughs, backwaters and sluggish sandy pools of small to large rivers (Ref. 5723, 86798).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00455 - 0.02896), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.1 ±0.2 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100).
