86798).In fresh water, usually occurs at the surface of clear, quiet water over sand or gravel. Subsequent decline in distribution and abundance of the native brook silverside (Labidesthes sicculus) led to speculation that dietary competition with M. audens might be occurring. 93252). What's In a Name? Species fed predominately upon cladocerans (60% of total number of food organisms, with largest category, Sididae, representing 32%). 10294), invertebrates, fish eggs and larvae and diatoms (Ref. Major food organisms in the diet were from the following groups: Sididae, Chydoridae, Ceriodaphnia, Bosmina, Cyclopoida, nauplii, and Ostracoda. The genus name, Labidesthes was derived from the two words: labidos, forceps and esthio, eat.

Brook silversides are found in many lakes of central Minnesota and in the Mississippi and St. Croix rivers.
The species meaning of sicculus is less clear. As the eggs of bass, gar, and chub develop and move into the water collumn, the inland silverside has been known to forage on them in great quantities.
The Mississippi silverside (Menidia audens) is now common throughout the waterway and apparently invaded from the Tennessee River after man-made connection with the Tombigbee River in the mid 1980s. The Brook Silverside species was described by Edward Drinker Cope from a Michigan holotype in 1865. Some landlocked populations, many of which have been established in impoundments as forage for sport fishes, reproduce in fresh water (Ref. ... (brook silverside). There are about 104 species within thirteen genera found in euryhaline, marine, and freshwater habitats distributed throughout the tropical and temperate waters of the Western Hemisphere. It refers to the prolonged jaws, which form a short, depressed beak (see photo). Brook silverside: named for the silver band on its side Labidesthes (lah-beed´-ess-theez) a word meaning forceps (a dissection tool) in Greek, most likely referring to the jaws. This fish can be differentiated from the brook silverside by the dark scale pigmentation on the dorsal portion of the body, as well as the anal fin extending only to the edge of the dorsal fin. 5723).Feeds on zooplankton (Ref. Atherinopsids, or neotropical silversides, belong to the order Atheriniformes and family Atherinopidae.
