Etymology: Nematalosa: Greek, nema, -atos = filament + 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).
Eponymy: Marcus Élieser Bloch (1723–1799) was a German physician and naturalist specialising in ichthyology. [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 15 - 19; Anal spines: 0; Anal soft rays: 21 - 25. Diagnosis: Body rather deep, its depth about 34-41% of standard length, belly with 17-20 + 9-13 scutes, total 28-32 scutes; anterior arm of pre-operculum with the third infra-orbital bone immediately above it, no fleshy gap between; mouth inferior, lower jaw strongly flared outward; last dorsal finray filamentous; pectoral axillary scale present; hind edge of scales distinctly toothed; a dark spot behind gill opening (Ref. 188). Resembles Nematalosa galatheae, which has spots along the flank and a smooth hind edge to scales; Nematalosa arabica, N. come and N. japonica all have a distinct fleshy triangular area above the anterior arm of the pre-operculum and none have toothed scale edges; no other clupeid in the distribution area of Nematalosa nasus has a filamentous dorsal finray (Ref. 188).
Known from estuaries and coastal areas, occasionally ascending into the upper reaches of the tidal zone (Ref. 12693). A filter-feeder. Marketed fresh, dried-salted or boiled. Made into fish balls. Very bony.

Estimates based on models
Preferred temperature (Ref. 123201): 25.2 - 29.2, mean 28.6 °C (based on 1229 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00765 - 0.00991), b=3.05 (3.02 - 3.08), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278): 2.2 ±0.09 se; based on food items.
Generation time: 1.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
