Bleak Future for Central Valley Wild Salmon

 

            In a recently published paper by Sierra Franks and Robert Lackey
of Oregon State University, most surveyed fisheries experts concluded that
by 2100 wild salmon in the California Central Valley will be extirpated or
minimally abundant if current trends continue.  The experts provided their
candid assessments with a promise of complete and permanent anonymity.
Despite restoration efforts spanning decades and involving large
expenditures, runs of wild salmon in the Central Valley continue to decline.
The causes of the decline are many and have been well studied.   Given the
most probable policy and ecological scenarios (i.e. effects of continued
harvest, continued stocking from hatcheries, changing climate, continued
human population growth and associated demands for scarce water resources)
and based on expert judgment by fisheries experts, Franks and Lackey
projected the most likely future of wild salmon runs in the Central Valley
in 2100 and it is not promising.  The paper was published in the current
issue of  <http://escholarship.org/uc/item/3vt5z15p> San Francisco Estuary
and Watershed Science and is available for free download.
