Short description Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία

Σπόνδυλοι: 38 - 39. Body dark brown, covered with minute papillae. Some or all barbels distally branched one or more times, retaining a constant width along its length. Oval premaxilla shorter than maxilla. Teeth arranged in 2 rows. Pectoral fin rounded. Dorsal fin with 3-4 procurrent and 6-7 principal rays. Anal fin with 3 procurrent and 8-9 principal rays. Caudal fin truncate with 9-12 dorsal procurrent, 13 principal and 10-11 ventral procurrent rays (Ref. 45128).

Collected from a pre-andean stream of clear water, with shallow, sandy bottom, and with vegetation along margins, at an elevation of about 3,680 m above sea level. Specimens were hiding in the sand. Stomach contents include mainly chironomid larvae (Diptera) and amphipod remains and sand (Ref. 45128),

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00851 (0.00355 - 0.02043), b=2.93 (2.74 - 3.12), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Τροφικό Επίπεδο (Ref. 69278): 3.2 ±0.46 se; based on food items.

Ελαστικότητα (Ref. 120179): Χαμηλό, ελάχιστος χρόνος για διπλασιασμό πληθυσμού 4,5 - 14 έτη (Assuming Fec < 100).

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