Teleostei (teleosts) > Siluriformes (Catfishes) > Claroteidae (Claroteid catfishes)
Etymology: Bathybagrus: Greek, bathys = deep + Greek, pagros = a fish (Dentex sp.) (Ref. 45335).
Eponymy: Rudolf Grauer (1870–1927) was an Austrian explorer and zoologist who collected extensively during an expedition to the Belgian Congo (1909) and again (1910–1911) on an expedition paid for by the Austrian Imperial Museum. [...] (Ref. 128868), visit book page.

Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 36.0 cm TL male/unsexed; (Ref. 3236); max. published weight: 515.00 g (Ref. 3236)

Most common in sub-littoral area but extend to 150 m, with larger individuals at greater depths. Inhabits muddy bottoms (Ref. 6868). Feeds mainly on fish (Ref. 4967). Oviparous (Ref. 205). Male parent guards the eggs (Ref. 45232).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.75 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100).

Price category (Ref. 80766): Unknown.

Bathybagrus graueri (Steindachner, 1911)
