Inland Silverside
Menidia beryllina (Cope, 1867)
Ray-finned Fishes

Habitat [-]
Inland silversides can be found in the shallows of tidal salt marshes and estuaries, showing a stronger preference for low salinity waters. They can also be found in freshwater ponds, lakes, and reservoirs and have been introduced into some locations (Smith 1985, Weinstein 1986). Spawning habitat includes shallow fresh or brackish waters with an ample amount of dead leaves, tree roots, algal mats, or aquatic plants for the eggs to adhere to (Weinstein 1986).

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 [-]
  • Atlantic Silverside (Menidia menidia)
