Figure 4. Relationship among inriver fishing mortality (FR), ocean fishing mortality (FC) and total fishing mortality (FT) of Connecticut River shad.
Figure 5. Relationship between shad run size (SHADPOP) and the overfishing threshold (NMSY) based on the Gompertz external production model.
Figure 6. Relationship among the various striped bass abundance estimates that were scaled to the same units. STRIP=tag based abundance of ages 7+ stripers, STRIP2=VPA based striped bass abundance of ages 7+ fish, STRIP LIS= Long Island Sound indices of striped bass, and STRIPRIV=electrofishing indices of age 7+ striped bass in the river.
