Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 1; ऐनल सौफट रेज़: 59 - 73; जानवरों की रीड़ का जोड़: 50 - 57. Diagnosis: 13-16 gill rakers on lower limb of first gill arch; 57-75 branched anal-fin rays; eyes positioned dorso-laterally; adipose fin always absent (Ref. 43912, 57127, 81643). Often with a post-occipital hump, a character also sometimes found in Schilbe intermedius whose head profile is extremely variable (Ref. 57127, 81643). Posterior nostrils closer to each other than are anterior ones; nasal barbel at maximum reaching to midway between eye and opercle, but generally shorter; inner side of pectoral spine feebly serrated (Ref. 43912).

Adapted to riverine and lacustrine conditions; appears to live mainly in the open waters; predatory, carnivorous but not strictly piscivorous; young essentially entomophagous (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Especially in the Chad basin of some economic value to the fishermen (Ref. 43912). Maximum reported total length 45 cm (Nile basin)(Ref. 43912).

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=0.00589 (0.00269 - 0.01291), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (K=1.30; tmax=3; assuming fec > 10,000).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (34 of 100).

Price category (Ref. 80766): Unknown.
