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...

A tide gate on the Savannah Back River, constructed by U.S. Army Corps of Engineers, might decrease survival of the striped bass (Marone saxatilis) eggs and larvae spawned near Savannah, Georgia. An initial season of sampling, with the tide gate held open, yielded striped bass eggs and larvae both up- and downstream from the gate. The distribution of eggs and larvae under normal conditions was established. Maximum numbers of striped bass eggs did not reveal 21m 3 • Spawning occurred at temperatures between 17 and 23 C but 3 spawning peaks coincided with temperatures between 19.5 and 21 C....
