Description synthétique Morphologie | Morphométrie

Fewer sawteeth (normally 19, rarely 20 on a side). First dorsal fin originate in advance of the origin of the pelvic fins and much more deeply concave posterior margins of the dorsal fins. Saltwater species when fresh-caught, either dark gray or golden brown, while freshwater species are mouse gray with reddish along midback posterior to first dorsal fin, reddish posterior to lower part of sides, first dorsal pale yellow with reddish free rear corner; second dorsal, pelvic fins, caudal and lower sides posterior to first dorsal dull brick red. Reddish tint either normal or result of suffusion with blood below the skin (Ref. 6902).

Inhabits shallow water in the vicinity of the shore and estuarine, particularly lagoons. Generally thought to rarely descend below 10m but have been found at 122m in Lake Nicaragua (Ref. 55273). Tends to run farther upstream in large rivers. Found in temperatures higher than 20-30°C (Ref. 6902). Ovoviviparous (Ref. 50449). Minor commercial, for the curio trade (Ref. 37548).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Estimates based on models

Preferred temperature (Ref. 123201): 26.1 - 28.5, mean 27.6 °C (based on 544 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5234 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00832 (0.00404 - 0.01712), b=3.00 (2.81 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 4.0 ±0.6 se; based on size and trophs of closest relatives

Generation time: 12.3 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Catégorie de prix (Ref. 80766): Medium.
