Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Body and head grayish with fine black line along midside and a black blotch on the anal fin. Tail with a black oval blotch on its base (lacking in some individuals found in Río San Juan). Snout sharp and pointed. Anal fin shorter than head length. B. cascajalensis differs from this species in the absence of the black blotch on the base of the tail (mitochondrial DNA implies that the two are valid) (Ref. 36880).

Lives in current of low to moderate velocity between 5-50 m of elevation; at temperatures of 23-34°C. Found near the surface along large river banks, but not common in streams. Feeds on terrestrial insects and in small quantity on aquatic insects. Reproduces throughout the year (Ref. 36880).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00813 (0.00354 - 0.01865), b=3.16 (2.97 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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

Brachyrhaphis parismina (Meek, 1912)
