Eponymy: Ignác (Ignatius) Fürth was the Austrian Consul (1871) at Panama. He donated many fish specimens to the Vienna Museum. (Despite the name ‘Congo’ Sea Catfish, the species is found in Central America!) (Ref. 128868), visit book page.

Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Spine anali: 0; Raggi anali molli: 46 - 50. Body moderately slender, belly with 23 to 25 + 11 to 14 scutes. Eye large, lower jaw projecting; gap between hind tip of premaxilla a ligament, not a toothed bone. Dorsal fin origin a little before midpoint of body; anal fin long, its origin below about last dorsal fin rays.
Occurs in coastal waters, entering estuaries, perhaps to spawn there (Ref. 9336). Feeds on planktonic crustaceans; larger individuals feed on shrimps (Ref. 9336). Flesh of low quality (Ref. 9336).

Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00401 - 0.01981), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Trophic level (Ref.
69278): 3.5 ±0.52 se; based on food items.
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
