Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 8; Dorsal soft rays (total): 9 - 10; Anal spines: 3; Anal soft rays: 9 - 11. Diagnosis: Ambassis ambassis has the following combination of characters: a single supraorbital spine; rostral spine absent; preopercle ridge and rear margin serrate; interopercle edge smooth except for few small serrae at angle; 2-3 rows of cheek scales; predorsal scales 13-18; lateral line continuous (normally); lower gill rakers 19-23; pectoral-fin rays 14-15 (Ref. 50956).

Biology     Glossary (e.g. epibenthic)

Tolerant of freshwater when water temperature is within 7-32°C (Ref. 7248, 79840). Tends to be more tolerant of lower temperatures in water of low salinity (2ppt) than in seawater (Ref. 7248). Feeds at night on crustaceans, fish fry and larvae and insects (Ref. 7248). Salt dried and eaten in some countries (Ref. 12484)

Estimates based on models

Preferred temperature (Ref. 123201): 23.9 - 28.8, mean 27.3 °C (based on 254 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00826 - 0.02530), b=2.99 (2.84 - 3.14), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.56 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).
