Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 11; Anal spines: 0; Anal soft rays: 8. Diagnosis: last simple dorsal-fin ray smooth on hind margin; scale formula 3.5/22-25/4.5-5.5; 3-3.5 scales between lateral line and pelvic-fin base; 4-6 anterior scales pored; 10 scales around caudal peduncle; lateral-line scales without particular colour pattern; 8 branched dorsal fin rays; no barbels; lateral line incomplete, straight; maximum reported size 30 mm SL; small spot at end of caudal peduncle (Ref. 2940, 81282).

Affinities: superficially similar to B. salessei (complete lateral line, without barbel); B. clauseni is also related to B. sylvaticus, the latter having only 8 scales around the caudal peduncle and no pored scales in the lateral line; the distance between the type localities of these two species is only 100 km (Ref. 2940). Maximum TL was recorded at 4.2 cm (Ref. 2801).

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=0.01230 (0.00558 - 0.02710), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.3 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).

Enteromius clauseni (Thys van den Audenaerde, 1976)
