Environment / Climate / Range
Marine; brackish; pelagic-neritic; oceanodromous (Ref. 51243); depth range 0 - 3 m (Ref. 85409). Temperate; 1°C - 33°C (Ref. 35682); 60°N - 25°N, 82°W - 52°W
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm TL male/unsexed; (Ref. 7251); common length : 11.5 cm TL male/unsexed; (Ref. 12193); max. reported age: 2 years (Ref. 12193)
Western Atlantic: Gulf of St. Lawrence in Canada to northeastern Florida in USA.
Adults feed on copepods, mysids, shrimps, small squids and marine worms (Ref. 7251); also eggs of their own species (Ref. 5951). Preyed upon by striped bass (Ref. 7251) and bluefish (chief predators) (Ref. 5951). Oviparous, eggs are deposited on the substrate during a spawning run along the shore (Ref. 38155). Silversides are sometimes used as live food for trout (Ref. 7251).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00246 - 0.00810), b=3.12 (2.95 - 3.29), based on LWR estimates for species & Subfamily-BS (Ref. 93245
Trophic Level (Ref. 69278
): 3.2 ±0.3 se; Based on diet studies.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (K=1.1-1.4; tmax=2).
Vulnerability (Ref. 59153
): Low vulnerability (13 of 100) .
