Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 8; Rückenflossenweichstrahlen (insgesamt): 9-11; Afterflossenstacheln 3; Afterflossenweichstrahlen: 9 - 11. Diagnosis: Ambassis natalensis has following combination of characters: supraorbital spines 1-4; rostral spine absent; rear margin of preopercle entirely serrate; preopercle ridge smooth except for 1-5 tiny spines at rear corner; interopercle smooth or with 1-4 tiny serrae at angle; two rows of cheek scales; predorsal scales 9-11; lateral line continuous; lower gill rakers 19-22; pectoral-fin rays 14-15; teeth on vomer and palatines in 2-3 rows (Ref. 50956).

Tolerant of freshwater within a temperature range of 19-27°C (Ref. 4180, 52193, 79840). In summer, it feeds mainly in early evening and late morning while in winter, it feeds both day and night on crustaceans as well as insects (aquatic and terrestrial) and fish (Ref. 7248, 52193). Excellent subject for biological research as it easily thrives in captivity (Ref. 12484).

Estimates based on models

Preferred temperature (Ref. 115969): 23.9 - 27.6, mean 26.7 (based on 82 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01413 (0.00728 - 0.02742), b=3.02 (2.85 - 3.19), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.59 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Assuming Fec > 10,000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
