The claim is 100's of millions salmon feared dead due to Fukushima. The picture provided is from Adams river British Columbia 2012 & the picture source is 2010 after salmon run upstream they spawn & die.. and the numbers a bit inflated as likely 10 to 100.000 thousand not millions.Hundreds of millions of Pacific salmon are missing, presumed dead, along the US west coast amid fears that ocean life are dying in “stunning numbers” following the Fukushima disaster in Japan. According to The California Department of Fish and Wildlife, preliminary data from the Sacramento River indicates that salmon runs have dropped to record low levels.

i thought this be easy debunk,, well the picture part was but its get tricky drawing in complex cause and effect upon salmon population. It seems that the fish numbers have been dropping over past 30 years & 2016 is bad season but no claim is made by authority that cause is Fukushima fall out & thats its most likely warming oceans climate change over fishing or other ocean environmental impact..

Overview of the 2016 Salmon Season & Outlook for 2017

Summary:
.....
- Warm ocean conditions and variable freshwater conditions led to reduced salmon returns coastwide
- Reports by DFO’s Conservation and Protection Branch indicate high levels of non-compliance in several important fisheries
- The level of core stock assessment funding for salmon reached an all-time low in 2016, leaving critical gaps in the monitoring of our salmon runs
- Recent environmental conditions that are detrimental to salmon production will likely reverberate through 2017 – 2019, suggesting returns will continue to be both highly variable and unpredictable
Scientists first detected what became popularly known as “the blob”1 in 2013. This vast area of abnormally warm water grew to around nine million square kilometers. It slowly dissipated during 2015, but was followed by a powerful El Niño event lasting from 2015 through much of 2016.
As a result of the abnormal ocean conditions present from 2014 through 2016, warm waters dominated the North Pacific ecosystem, ushering in new predators and unusual zooplankton. Many salmon entering the marine environment in 2014 did not fare well, with some—like some interior Fraser sockeye and stream-type Fraser chinook runs—returning in very low numbers.
