Maturity: Lm ?  range ? - ? cm
Max length : 200 cm TL αρσενικό/απροσδιόριστο; (Ref. 58490); common length : 81.7 cm TL αρσενικό/απροσδιόριστο; (Ref. 12193); μεγ. δημοσιευμένο βάρος: 130.0 kg (Ref. 52332); μεγ. αναφερόμενη ηλικία: 41 έτη (Ref. 32514)

Short description Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία

Absence of scalelike scutes on belly; bases of outer barbels usually behind bases of inner barbels (Ref. 86798).

Βιολογία     Γλωσσάρι (π.χ. epibenthic)

Adults inhabit large, deep, turbid river channels, usually in strong current over firm sand or gravel (Ref. 10294, 58490). They feed on aquatic insect immatures, particularly caddisfly larvae, and small fish (Ref. 10294). Threatened due to over harvesting and habitat loss (Ref. 58490). No length type given but assumed to be in TL.

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=0.00407 (0.00149 - 0.01114), b=3.16 (2.92 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Τροφικό Επίπεδο (Ref. 69278):  3.9   ±0.63 se; based on food items.
Generation time: 16.8 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Ελαστικότητα (Ref. 120179):  Χαμηλό, ελάχιστος χρόνος για διπλασιασμό πληθυσμού 4,5 - 14 έτη (tm=5-15; Fec=170,000, tmax=41(based on 1 specimen only)).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (67 of 100).
