Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 16 - 24; Anal soft rays: 15 - 21. This species is distinguished from its congeners by the following characters: 2 supraneural bones; spinous process (hypurapophysis) on the anterosuperior border of the parahypural bone (hypural complex); sagitta otolith elliptical and smooth-lobed margins, rostrum process short, posterior region of the otolith straight or flat, the aspect ratio of sagitta otoliths AR = 0.585, the roundness index Rd = 0.543; morphometric index 0.735: mean head length 35.01% SL, mean diameter of the orbit 7.73% SL, mean pre-orbital depth 0.14% SL, mean snout length 5.36% SL (Ref. 126783).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.03467 (0.01654 - 0.07268), b=3.01 (2.81 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec<1000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).

Price category (Ref. 80766): Unknown.

Astronotus crassipinnis (Heckel, 1840)
