Short description Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία

Σπόνδυλοι: 40 - 42. Body spots absent in adults. Elongated body with slightly convex dorsal profile. Head length longer than body depth. Snout length much longer than postorbital head length. Lips well developed, lateral lobes of lower lip broad and thick, with folds, the median process small. Barbel length slightly thick, shorter or equal to eye diameter. Dorsal spine strong, 2/3 of HL. Origin of dorsal fin nearer the tip of snout than the caudal base. Gill rakers more than 15 (Ref. 38453). Anal fin with 6 1/2 branched rays; last simple dorsal rays ossified, spine-like (Ref. 43281).

Omnivorous, feeding mainly on benthic invertebrates (Ref. 41299). Females are larger than males (Ref. 1441).

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=0.00708 (0.00586 - 0.00855), b=3.10 (3.05 - 3.15), in cm total length, based on LWR estimates for this species (Ref. 93245).

Τροφικό Επίπεδο (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

Generation time: 6.6 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Ελαστικότητα (Ref. 120179): Μεσαίο(α), ελάχιστος χρόνος για διπλασιασμό πληθυσμού 1,4 - 4,4 έτη (tm=3-4; k=0.16-0.19).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (55 of 100).

Price category (Ref. 80766): Unknown.
