Classification / Names Common names | Synonyms | Catalog of Fishes( genus , species ) | ITIS | CoL | WoRMS | Cloffa

Teleostei (teleosts) > Siluriformes (Catfishes) > Schilbeidae (Schilbid catfishes)
Etymology: Siluranodon: Greek, silouros = a cat fish + Greek, odous = teeth (Ref. 45335 ) ;   auritus: From the Latin "auritu" (literally "listening"), referring to the local Arabian name of this species in Egypt, "schilbe oudney", which means "schilbe with ear" (those "ears" probably refer to the large rounded pectoral fins just behind the head)(Ref. 43912). .

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; demersal; potamodromous (Ref. 51243 ). Tropical; 35°N - 5°N

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Africa: Nile basin (Ref. 3570 , 28714 , 43912 ) and Chad, Niger, Volta and Comoe rivers (Ref. 57127 ).

Length at first maturity / Size / Weight / Age

Maturity: L m   ? , range 9 - ? cm
Max length : 14.0 cm SL male/unsexed; (Ref. 57127 )

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 5; Anal spines : 0; Anal soft rays : 67 - 87. Diagnosis: 67-87 anal-fin rays; 49-60 thin and flexible gill rakers on lower limb of first gill arch; 4 pairs of well developed barbels; small, spineless dorsal fin with 4-5 branched rays; jaws and palatine bones entirely without teeth (Ref. 43912 , 57127 ).

Biology     Glossary (e.g. epibenthic)

Pelagic, occurs large and moderate lakes and rivers (Ref. 43912 ). In the Sudd, they occur beneath fringing Eichornia (Ref. 28714 ). Microphagous, feeding mainly on algae and occasionally rotifers, planktonic and benthic crustaceans, immature insects (Ref. 43912 ) and mud/debris (Ref. 28714 , 43912 ). Probably reproduces during the floods, migrating from lakes to rivers; howver in Lake Kainji fish were reported to migrate from the river to the Lake to spawn (Ref. 43912 ). Oviparous, eggs are unguarded (Ref. 205 ). Max. reported total length 175 mm (Ref. 3570 , 43912 ). Might locally represent an important species for fisheries since it is sometimes extremely abundant, but this may be negated by its small size (Ref. 43912 ).

Estimates based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00676 (0.00356 - 0.01283), b=2.98 (2.81 - 3.15), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245 ). Trophic level (Ref. 69278 ):  2.9   ±0.34 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 vulnerability (10 of 100). Price category (Ref. 80766 ):   Unknown .
