Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 14 - 17; Spine anali: 0; Raggi anali molli: 28 - 33. SL/BD = 4.4-6.1. Dorsal much smaller than anal inserted almost midway from origin of anal (Dorsal-Anal fin base ratio 0.32-0.46). Pectorals at most as long as head with posterior end not extending beyond origin of pelvic fins. Thin caudal peduncle with height 22.6-31.5 x SL. Color similar to B. brachyistius. Snout projecting and curved downward.(Ref.4967)

Affinities: related to Brienomyrus brachyistius, distinguished by longer anal fin in Brienomyrus longianalis and by lower peduncle height SL ratio. May be limited to the delta and the lower reaches of rivers (Ref. 3203).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00661 (0.00358 - 0.01221), b=2.68 (2.52 - 2.84), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.2 se; based on diet studies.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Fec=417-2,252).

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