Aspects of the Population Dynamics of Striped Bass (Morone Saxatilis) Spawning in Maryland Tributaries of the Chesapeake Bay

摘要

This is a study of mortality and migration processes that influence the population structure and harvest of adult striped bass spawned in the Maryland tributaries of the Chesapeake Bay and an examination of the influence of stock size on the reproductive success of the population. A model of the adult stock was developed that incorporates the age and sex specific nature of Striped Bass migratory patterns and mortality rates. The model was used to address a number of resource management issues including estimating the effects of a 14 inch minimum size limit in Maryland and the consequences of a reduction in year class strength through power plant operations.
