Etymology: Crenicichla: Latin, crenulatus = cut, clipped + Greek, kichle = wrasse (Ref. 45335);  empheres: Name from Greek meaning similar, alludes to its similarity with C. jurubi, a species occurring in the same drainage; an adjective..

Short description Morphology | Morphometrics

This species is distinguished from other species of the C. missioneira group by having 6-8 slightly elongate blotches along middle portion of the body flank, below the upper lateral line scale row, no lateral band, numerous spots scattered over back, (sometimes forming a reticulated pattern) and sides in males, and an isognathous mouth. It is most similar to C. igara and C. jurubi in color pattern, but both males and females of the latter species show the same scattered spots including those on the head and opercle vs. none in females and males of Crenicichla empheres which has the spots confined to the lateral of body. Other differences, C. jurubi may have the last three or four blotches contiguous without lighter space between them and/or mixing with the spotted pattern of the body) and C. igara has prognathous mouth and no ocellated spot on the dorsal fin in females (Ref. 75870).

Biology     Glossary (e.g. epibenthic)

The specimens were collected above a major waterfall in the rio Chapecó. Although many other localities were explored downstream and in the rio Uruguay itself, no additional specimens were captured. Stomach contents of one female specimen (9.32 cm SL, MCP 40176) contain aquatic insect larvae (Ref. 75870).

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=0.00813 (0.00354 - 0.01865), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
