Actinopteri (ray-finned fishes) > Osmeriformes
(Freshwater smelts) > Osmeridae
Etymology: Osmerus: Greek, osme = odorous; similar to freshly cut cucumbers (Ref. 45335). More on author: Cope.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; depth range - m (Ref. ), usually - m (Ref. ). Temperate; 0°C - ; 59°N - 37°N
North America: Heney Lake in southern Quebec, Lake Utopia in southern New Brunswick in Canada, Wilton Pond and Green Lake in southern Maine, USA. Introduced into Meach and Ouimet lakes in southern Quebec. May be present in other lakes in eastern Canada and New England, USA.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 17.0 cm TL male/unsexed; (Ref. )
Lives in small, deep, thermally stratified lakes. When this species occurs with Osmerus mordax, it usually spawns later in the year, feeds on smaller food items, grows more slowly, matures earlier in life, and has a shorter life span.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00363 (0.00178 - 0.00741), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.45 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (27 of 100) .
