Etymology: Escualosa: Latin, squaleus, squalidus = with rough skin + Latin, alausa = a fish cited by Ausonius and Latin, halec = pickle, dealing with the Greek word hals = salt; it is also the old Saxon name for shad = "alli" ; 1591 (Ref. 45335).

Max length : 10.0 cm SL male/unsexed; (Ref. 188); common length : 8.0 cm SL male/unsexed; (Ref. 188); max. reported age: 1.00 years (Ref. 43081)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 13-21; Anal spines: 0; Anal soft rays: 14 - 19. Belly strongly keeled. The almost rectangular second supra-maxilla and the bright silver stripe along the flank distinguish it from juveniles of Sardinella, Amblygaster and Herklotsichthys. Resembles some pellonulines with a silver stripe, but they lack a first supra-maxilla. Distinguished from E. elongata of the Gulf of Thailand but its deeper body and broader silver stripe.

Biology     Glossary (e.g. epibenthic)

Forms schools in shallow waters, the juveniles apparently entering the lower parts of rivers, but returning later to the sea. Feeds on both zooplankton (copepods, crab zoea, larvae of bivalves and fish eggs) and phytoplankton. Breeds from October to February (mainly November to January) off western coast of India, usually in relatively shallow inshore waters. Marketed fresh and dried-salted.

Estimates based on models

Preferred temperature (Ref. 123201): 26.7 - 29.1, mean 28.4 °C (based on 1160 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00514 - 0.01173), b=3.05 (2.93 - 3.17), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.1 se; based on diet studies.
Generation time: 0.6 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (tmax=1).
