This is 2nd/3rd/4th hand information, so I cannot verify its accuracy. There is a thread on iFish to this effect:

"He was also told that due to the over 3000 Sea Lions and Seals consuming on average 3 salmon a day in the Cloumbia, no counts going thru Bonneville, the gill netters getting their quota, that the fishery may be cut off on April 8 do to poor, less than expected numbers coming thru the system."

Again, this could be a total miscommunication, but I wanted to throw it out there in case any of you are in a position to verify or debunk it.
