Effect of the Savannah Tide Gate on Striped Bass Egg Distribution and Survival During 1977 and 1978

A comparison of striped bass, Morone saxatilis, egg abundance, distribution and survival during 2 years in the Savannah River estuary gave some indications of the possible effects of the Savannah River Tide Gate on the spawning success of this species. Eggs are more likely to be found farther upstream when the tide gate is in operation. Apparently striped bass respond to increased salinities by spawning farther upstream. By using egg stage as a measure of age, survivorship curves based on relative abundance of the different egg stages were calculated. While the 1977 data were of limited...


Comparison Of Growth Rates And Abundance Of Largemouth Bass In Selected North Carolina Coastal Rivers

Age-growth relationships, length-weight relationships, and relative abundance ind ices were determined for largemouth bass (Micropterus salmoides) collected from the Cape Fear, Chowan, Pasquotank and Tar-Pamlico river systems in North Carolina during 1976. Largemouth bass in the Pasquotank River had the highest mean annual growth rate during their first and second years when compared to those in the other river systems studied. Largemouth in the Tar-Pamlico River system had the highest mean annual growth rates for age groups III and older. The growth rate of the Chowan River largemouth...
