Gizzard Shad Reproductive Biology and Predator-Prey Relations with Walleyes in Western South Dakota Reservoirs

, 2005
Gizzard shad Dorosoma cepedianum were introduced into Angostura, Orman, and Shadehill reservoirs during the 1990s to potentially provide increased prey resources for walleye Sander vitreus.

FMRFamide effects on spontaneous and induced contractions of the anterior gizzard in Aplysia

, 1983
The effects of FMRFamide (Phe-Met-Arg-Phe-NH2), YGG-FMRFamide (Tyr-Gly-Gly-Phe-Met-Arg-Phe-NH2), and Met-enkephalin (Tyr-Gly-Gly-Phe-Met) on the isolated Aplysia anterior gizzard were examined. (i) FMRFamide inhibits spontaneous gut activity.

Modelling phenotypic flexibility:An optimality analysis of gizzard size in Red Knots Calidris canutus [PDF]

, 2006
Reversible phenotypic changes, such as those observed in nutritional organs of long-distance migrants, increasingly receive the attention of ornithologists. In this paper we review the cost-benefit studies that have been performed on the flexible gizzard

Influence of Gizzard Shad on Black Crappie populations in prairie impoundments of Western South Dakota

Aquaculture, Fish and Fisheries
Gizzard Shad Dorosoma cepedianum have been introduced into Western South Dakota reservoirs and shown to improve the growth and size structure of sportfish, particularly Walleye Sander vitreus. Black Crappies Pomoxis nigromaculatus are a popular sportfish

Influence of Gizzard Shad on Fish Community Ecology in Northeastern South Dakota Glacial Lakes

, 2011
Walleye Sander vitreus are the most popular sport fish in South Dakota, while yellow perch Perca flavescens are important both ecologically as prey for walleye and economically as an important sport fish themselves.

Population Characteristics of Gizzard Shad Introduced into a Small Western Oklahoma Impoundment

, 2019
Gizzard Shad (Dorosoma cepedianum) are often considered a vital forage species in many aquatic systems. However, when populations of Gizzard Shad become dominated by large (>200 mm) overabundant individuals they can have negative direct and indirect ...

Gizzard Motility in Relation to Oviposition in the Chicken

Poultry Science, 1986
Changes in gizzard motility were studied with a particular reference to egg laying by a radiotelemetric measurement of electrical activity of the thick caudodorsal muscle of the gizzard in the chicken. There was a clear diurnal pattern in gizzard motility.
