Atlantic Silverside
Menidia menidia (Linnaeus, 1766)
Ray-finned Fishes

Habitat [-]
Atlantic silversides inhabit fresh, brackish, and salt water marshes in the lower Hudson River estuary and Long Island from the spring through the fall, although they may not be as inclined to enter fresh water as the inland silverside (Smith 1985). They migrate out to deeper waters during the winter (Fay et al.1983).

Associated Ecological Communities [-]
  • Tidal river
    The aquatic community of a river under the influence of daily lunar tides. We restrict this community to the continuously flooded portions of the river where plants do not grow out of the water. A deepwater zone has depths averaging more than 2 m (6 ft) at low tide. Salinities at any one place in the river may fluctuate as the tides flow in and out.

Associated Species [-]
  • Inland Silverside (Menidia beryllina)
