If
you want to catch big salmon again on the Sacramento, you need to TAKE
ACTION NOW! I attended
the PFMC meeting on Mar 8th in Sacramento and was deeply disappointed
that after the lowest return of fall salmon ever recorded that PFMC was
even considering opening a commercial season targeting these fish this
year based on a fantasy that their so-called scientists brewed up based
upon a model that uses jack returns to predict the 2010 run. With a straight
face, their lead "scientist" said the following: "2009
Sacramento Fall Chinook return was 39,800. We predicted a return
of 122,100. Our prediction for 2010 is an abundance of 245,483 salmon"
WHAT?!? I'm sorry, but that is just pitiful. I am deeply concerned about opening any harvest, especially commercial, that would target the 2010 Fall Run Sacramento Chinooks because I believe the forecast of 245,483 salmon is grossly inflated and that we will be lucky to make minimum escapement. My reasons are as follows: 1. The predictive model that forms the basis for harvest decisions is too deeply flawed to be used when populations are at critically low levels. In 2009 the predictive model failed by more than 300%. Predicted salmon = 122,100 Actual salmon = 39,800. More simply, for every 3 salmon that the model predicted, less than 1 salmon actually materialized. If the model over-predicts to the same level this year, we will have only 82,000 salmon return - or 40,000 below minimum escapement goals. 2. Even if the model were correct, there is a problem with the 2009 jack count that feeds the model. The majority of the jacks were part of an anomalous, near historic return to the Feather River while the Upper Sacramento and American had very low returns of jacks. The Upper Sacramento that historically produced the lion's share of ocean harvested salmon received a very low jack return. Failure to protect depleted Upper Sacramento stocks will lead to disastrous results for future ocean harvests. 3. There is no historical precedent for a year over year increase in salmon abundance of 6 times as would be needed for the 245,483 salmon prediction to come true. The greatest year over year increase in Sacramento Fall Chinooks was 1994 - 1995 when the salmon abundance increased by a factor of 2.2 and even that is rare. Normal increases are measured in percentages, not factors of 2 or 3. Applying the optimistic 2.2 factor to the 2009 returns we can expect a maximum of 87,560 adult salmon in 2010 - a number far below minimum escapement. In
light of the above facts, I would urge the council to apply common sense,
rather than numbers from a highly flawed prediction model in making harvest
decisions for the 2010 Sacramento Fall Run Chinooks. Given the historically
low returns of 2009, a flawed prediction model, anomalously high returns
to the Feather Hatchery and lack of historical precedence, the only rational
decision is to close the harvest of 2010 Sacramento Fall Run Chinooks.
Any other decision will be both reckless and potentially disastrous to
this once stellar fishery. |
