Striped Bass Tagging and Harvest Regulations--Tues., Aug. 25, session 7

A long-term study of nearly 175,000 tagged striped bass on the East Coast revealed that fish survival rates are affected by changes in harvest regulations and that some of these rates are modified by factors such as fish age and sex. Since 1987, wild striped bass have been tagged in a east coast-wide study involving fifteen state and federal agencies. Data from three long-term tagging programs were used to assess the impact of substantial regulatory changes that took place from 1987 to 1998.

PCB Concentrations in Walleyes--Tues., Aug. 25, session 16 Walleye adult males in Saginaw Bay, which drains into Lake Huron, have significantly higher concentrations of PCBs than females, a recent study reveals. The higher concentrations in males are probably because they spend more time in contaminated areas of the watershed than females. ("Sexual Difference in PCB Accumulation Rates of Walleye," by C.P.
