ຊີວະສາດ     ຄຳແປສັບ (ຕ.ຢ. epibenthic)

Lives in streams and rivers and in lakes, where it prefers shore regions (Ref. 78218). More common in rivers than in lakes (Ref. 12526). Common in marginal vegetation of Kagera River (Ref. 4903). Replaces S. victoriae in shallow waters of Lake Victoria (Ref. 4903), prefers areas less than 20 m deep (Ref. 34290). Feeds on insects (Povilla and chironomid larvae) and molluscs (Ref. 12526). Oviparous (Ref. 205). Rarely grows to lengths greater than 15 cm SL (Ref. 34290).

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=0.01549 (0.00700 - 0.03427), b=2.88 (2.70 - 3.06), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
ຊັ້ນເຂດຮ້ອນ (Ref. 69278):  3.4   ±0.45 se; based on food items.
Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
ຄວາມຢືດຢຸ່ນ (Ref. 120179):  ຂະໜາດກາງ, ປະຊາກອນຕຳ່ສຸດທີ່ໃຊ້ເວລາສອງເທົ່າ 1.4 - 4.4 ປີ (Fec = 200).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (22 of 100).
