Descrição breve Chaves de identificação | Morfologia | Morfometria

White dorsal, anal and caudal margins; 3-3+1/2 scales between the lateral line and the base of the anterior dorsal rays; relatively small size (Ref. 27732).

Obligate air-breathing (Ref. 126274); Found in hill streams (Ref. 27732). Adults inhabit medium to large rivers, brooks, rapid-running mountain streams and stagnant water bodies including sluggish flowing canals (Ref. 12975). Feed at night on small fish, insects and crustaceans (Ref. 85309). Exhibit parental care, with the male brooding eggs and fry in his mouth (Ref. 85309).

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=0.00891 (0.00684 - 0.01161), b=2.99 (2.93 - 3.05), in cm total length, based on LWR estimates for this species (Ref. 93245).

Nível Trófico (Ref. 69278): 3.8 ±0.62 se; based on food items.

Generation time: 2.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resiliência (Ref. 120179): Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (K=0.50; Fec=389).

Fishing Vulnerability (Ref. 59153): Low vulnerability (23 of 100).

Categoria de preço (Ref. 80766): Unknown.
