Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 15 - 18; Spine anali: 0; Raggi anali molli: 16 - 18. Body very elongate and slightly compressed. Dorsal fin inserted usually anterior to a vertical through the origin of the anal fin. Green-silvery dorsally, grading to whitish below. A silvery band with a dark margin run along the side; a series of four or five blotches (absent in young specimens) on sides between the pectoral and anal fins. Dorsal and anal fins with dark edges.
Life cycle and mating behavior
Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve
Male pursues a slow-moving female and upon catching up with the female, will begin shuddering from side to side while the pair is oriented parallel to each other; the pair positions themselves close to submerged vegetation; male assumes a slight head-down position , with his anal fin curled under the female's vent; the pair begins trembling until a single large egg is released; each female produces about a dozen eggs per day; eggs hatch in about a week; no parental care (Ref. 44091).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00115 (0.00093 - 0.00141), b=3.12 (3.06 - 3.18), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.62 se; based on food items.
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (30 of 100).
Nutrients (Ref.
124155): Calcium = 284 [95, 708] mg/100g; Iron = 0.8 [0.4, 1.6] mg/100g; Protein = 16.7 [15.3, 18.3] %; Omega3 = 0.205 [0.082, 0.602] g/100g; Selenium = 36.6 [14.8, 85.7] μg/100g; VitaminA = 43.9 [18.2, 104.0] μg/100g; Zinc = 1.72 [1.04, 2.47] mg/100g (wet weight); based on
nutrient studies.
