Western Atlantic: Gulf of St. Lawrence in Canada to North Carolina, USA. Mainly a near-shore marine species, but far inland populations occur in lakes in Nova Scotia in Canada and in Hudson, Delaware and Susquehanna River drainages (Ref. 5723).

Tamanho / Peso / Idade

Maturity: L_m ? range ? - ? cm
Max length : 6.4 cm TL macho/indeterminado; (Ref. 5723); common length : 4.1 cm TL macho/indeterminado; (Ref. 12193); Idade máx. registada: 3.00 anos (Ref. 12193)

Adults occur mainly along weedy bays and backwaters, entering brackish water and to a limited extent, fresh water (Ref. 3814). Feed along the bottom, primarily on diatoms, worms and crustaceans by sucking in the prey with a pipetting action (Ref. 27549). Males build, guard and aerate the nest where the eggs are deposited (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 4.2 - 12.7, mean 6.4 °C (based on 228 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01047 (0.00408 - 0.02689), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.2 ±0.38 se; based on food items.

Generation time: 1.3 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resiliência (Ref. 120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (K=0.84; tmax=3).

Fishing Vulnerability (Ref. 59153): Low vulnerability (16 of 100).

Categoria de preço (Ref. 80766): Unknown.
