Regional Salmon Outmigration Study: Survival and Migration Routing of Juvenile Chinook Salmon in the Sacramento-San Joaquin River Delta During the Winter of 2008-09.

摘要

Juvenile Chinook salmon (Oncorhynchus tshawytscha) emigrating from natal tributaries of the Sacramento River may use a number of migration routes to navigate the Sacramento-San Joaquin River Delta (hereafter called the Delta), each of which may influence their probability of surviving. We applied a mark-recapture model to data from acoustically tagged juvenile late fall-run Chinook salmon that migrated through the Delta during the winter of 2008-09 to estimate route entrainment, survival, and migration times through the Delta.
