Distribution of larval fishes in the Winfield Pool, Kanawha River, and direct impacts of commercial navigation traffic on larval fish survival
… two sites with bongo and push nets. Cyprinids, clupeids, and <i>Aplodinotus grunniens</i> dominated collections. Main channel densities were a fraction of the densities along the shoreline, indicating the importance of the shoreline as a nursery. Diel trends in abundance were evident for several …

The feeding ecology of and carbon and nitrogen budgets for Engraulis capensis in the southern Benguela ecosystem
… regarding the diets of intermediate microphagous clupeids are: A) that they are herbivorous and B) that they are omnivorous, but consume mainly zooplankton. The former view has been employed to explain their abundance in upwelling areas, since their purported ability to efficiently utilise the …

Compatibility and complementarity of alewife (Alosa pseudoharengus) and gizzard shad (Dorosoma cepedianum) as forage fish in Smith Mountain Lake, Virginia
… for exploitative competition between the clupeids. Distributional analysis indicated that gizzard shad were primarily uplake and littoral while alewives were mostly downlake and pelagic. Alewives co-occurred with striped bass and walleye during the growing season and were crucial in …

Impacts of the Invasive White Perch on the Fish Assemblage of Kerr Reservoir, Virginia
… by weight). Piscivorous sportfish primarily ate clupeids, which are highly abundant in Kerr Reservoir. Analysis of sportfish performance before (1974 – 1987) versus after (1996 – 2005) white perch establishment indicated no change in abundance and growth of striped bass and largemouth bass. …

Analysis of the Trophic Support Capacity of Smith Mountain Lake, Virginia, for Piscivorous Fish
This investigation examined the adequacy of the forage base to meet current demand of piscivores in Smith Mountain Lake, Virginia. Surplus production, or the maximum sustainable supply, of alewife (Alosa pseudoharengus) and gizzard shad (Dorosoma cepedianum) were determined using data on the …
