In a nutshell.....


"recent series of low recruitments indicate that management action may be needed to reduce the risk of fishery collapse."

Actually, alot more to the results and story.

SoCal stocks reported to be declining and may require management. 

In contrast, CenCal stocks reported to be increasing with biomass above MSY, low impact from fishing, and increase due to large recruitment events driven by environmental conditions.

Quote from report:
"Central CA - The population is estimated to be well above the biomass associated with maximum sustainable yield (Bmsy) and fishing mortality is well below the fishing mortality rate associated with maximum sustainable yield (Fmsy) either using the estimated MSY quantities or the 25% proxy. The stock is estimated to have increased rapidly starting in 1995 (Figure S10). The increase in abundance is due to large recruitments, which appear to occur in a cyclic pattern, and the magnitude of the cycles increased after 1990."

I thought i had read it like that.
looks like a little good and a little bad.

thanks for the info John, I actually get interested in these studies form a Nat resource perspective.
