Kurzbeschreibung Morphologie | Morphometrie

Diagnosis: eye <60% of interorbital space; massive profile specially on anterior part (Ref. 2880, 81279). Three scale rows between lateral line and scaly process at pelvic-fin bases; rakers of first gill arch poorly developed; snout-dorsal fin length/snout-ventral fins length different from one; adipose fin grey or black (Ref. 81279). Inferior lobe of caudal and anterior end of anal fin red-orange (Ref. 2880).

Hydrocynus species are piscivorous, but may also eat Caridina and insects (Ref. 28714). Affinities: easily distinguished from two other species in West Africa from the number of scale-rows below lateral line, which is 3 instead of 2 (Ref. 81279).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00528 - 0.02495), b=3.00 (2.82 - 3.18), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.50 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (54 of 100).

Preiskategorie (Ref. 80766): Unknown.
