Filter-Feeding Rates of Gizzard Shad

Abstract: In laboratory feeding trials, gizzard shad Dorosoma cepedianum of 5.3–17.5‐cm standard length fed on zooplankton as pump filter feeders, collecting prey by a series of rapid suctions not directed at individual prey. Buccal volume, determined from plaster casts, increases as a power function of fish standard length. Pumping rates decrease exponentially with length. A model of filtering rate, the product of buccal volume and pumping rate, was corroborated by feeding trials in which gizzard shad cleared zooplankt… Show more

“…Further, gizzard shad switch from this form of particulate feeding to filter-feeding at about 25 mm (Cramer and Marzolf 1970;Guest et al 1990). As filter-feeders, gizzard shad are not size selective predators; rather, they consume zooplankton with little ability to escape (Drenner et al 1982). Gizzard shad >25 mm in our experiments may have been filterfeeding, thus capturing smaller, more vulnerable prey items rather than the larger, more evasive ones.…”

“…Secchi depth was likely an indirect measure of food abundance for gizzard shad. Secchi depths decrease with increases in phytoplankton abundance and suspended solid concentrations, which are both important food sources for gizzard shad (Drenner et al 1982b(Drenner et al , 1986Mundahl and Wissing 1987;Schaus et al 2002). Because of reduced access to bottom sediments during summer stratification, gizzard shad in these reservoirs probably fed mostly on suspended plankton and sediments as they were commonly captured with trawls in offshore locations in the epilimnion (P.H.…”
