摘要

The relationships between striped bass recruitment and egg production, larval growth and survival, and environmental conditions which larvae encounter were investigated in the Patuxent River in 1991. Quantitative surveys of ichthyoplankton, otolith aging of striped bass larvae, and a larval mark-recapture experiment were the principal methods of the investigation. Occurrences of striped bass eggs and larvae were mostly restricted to parts of the river above the maximum turbidity zone (20 C experienced significantly higher mortality rates than those which experienced intermediate temperatures.
