educe reproductive success. Immature salmonids remain in freshwater systems and may
be exposed to these modifications for years. These conditions reduce juvenile survival.
Salmonids are also a popular commercial resource and have faced significant pressure
from fishing. Although currently protected, illegal oceanic driftnet gear is suspected of
hindering salmon survival and recovery. Despite the protection of weaker salmonid
stocks from fishing, exploitation of more populous stocks may actually harm weaker
stocks. Hatchery-reared salmon have been and are still being introduced to bolster
stocks. However, the broader effects of this action are unknown.
California Coastal Chinook Salmon
Distribution
California Coastal (CC) Chinook salmon includes all naturally-spawned coastal Chinook
salmon spawning from Redwood Creek south through the Russian River as shown in
(Figure 6).
CC Chinook salmon are a fall-run, ocean-type fish. Although a spring-run (river-type)
component existed historically, it is now considered extinct (Bjorkstedt, Spence et al.
2005). Table 6 identifies populations within the CC Chinook salmon ESU, their
abundances, and hatchery input.
