Biology     Glossary (e.g. epibenthic)

Adults occur in coastal bays, harbors and deep lagoons, usually in some turbid plankton-rich waters. Form schools. Feed on phytoplankton (diatoms) and small zooplankton (cladocerans, ostracods, larval polychaetes, etc.) (Ref. 9684). Small groups were seen eating eggs of Cheilio inermis straight after spawning (Ref. 48637). Adult individuals feed on macroplankton such as larval shrimps and fish. Eggs and larvae are pelagic (Ref. 6769). Generally marketed fresh, frozen, canned, dried-salted, and smoked; also made into fish sauce (Ref. 9684).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00721 - 0.00960), b=3.04 (3.00 - 3.08), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.38 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (K=0.2-1.9; tm=1; tmax=4; Fec = 68,500).
Vulnerability (Ref. 59153):  Low vulnerability (18 of 100) .
Price category (Ref. 80766):   Very high.
