Calumet Harbor (Chicago, IL). It is dependent upon zooplankton and aquatic insect larvae for food. Notes Feeding Ecology of Brook Silverside, Golden Shiner, and Subyearling Pumpkinseed in a Lake Ontario Embayment James H. Johnson,* Marc A. Chalupnicki, Ross Abbett, Avriel R. … Ecological Role - The brook silverside serves as a prey (“forage”) fish for predatory fish and other animals. Caloric Densities of Selected Fish Prey Organisms in the Lower Mississippi River Michael A. Eggletona Department of Wildlife & Fisheries ... flathead catfish (Pytodictis olivaris; 70-200 mm), brook silverside (Labidesthes sicculus; 50- 100 mm), freshwater drum (Aplodinotus grunniens; 80-1 50 mm), white bass (Morone chrysops; 80-150 mm), and bluegill (Lepomis macrochirus; 70- 150 mm). Close up of head of Brook Silverside, by Uland Thomas They are often seen jumping out of water in seeking flying insect prey. overview; data; media; articles; maps; names; ebio327_fish15 cc-by-nc-4.0 Labidesthes sicculus (Brook Silverside) is a species of bony fishes in the family New World silversides. The diet composition of each species suggested that Brook Silverside were feeding at the surface (terrestrial invertebrates and aquatic surface dwelling hemipterans), whereas young-of-year Pumpkinseed (amphipods) and Golden Shiner (tipulids) were feeding on different benthic prey. The brook silverside lives in slow moving rivers and lakes from the Great Lakes to the Mississippi Basin and Gulf Coastal Plains; the brook silverside survives best in clear water with aquatic vegetation.

Ashley Smith. Calumet Harbor (Chicago, IL). Potential: Ideal forage fish and when abundant may be an important prey item for game fish (Scott and Crossman 1998). At a younger age, the brook silverside preys mostly on smaller fish. During winter, the brook silverside eats mostly planktonic crustaceans. Alvin Cahn made extensive observations on Brook Silverside in southern Wisconsin lakes. Individuals are known to live for 2 years and can grow to 13.0 cm. Its presence in numbers in waters with low turbidity is an indicator of clear water. In Sterling Pond, Brook Silverside were clearly surface feeders because their diet consisted mainly of terrestrial invertebrates and aquatic hemipterans, prey taxa that are found on the surface. Its presence in numbers in waters with low turbidity is an indicator of clear water. REPLACE Larval Brook Silverside. 2017. With this protection, as well as advanced anti-predator behavior, the brook stickleback is only a minor prey item. Brianna McDowell. Differences in feeding periodicity were most One prey includes the dance flies (Empididae), which frequently hover in large swarms just above the surface.
