Hi all-

 

Just a quick question...how concerned should I be about the warning "Poor convergence in Fmsy"?

 

Thanks,

Laura

Laura,
This means that the search for Fmsy did not achieve convergence criteria.  It could be close, or not.  The recommendation is to look at the iterations of the search, which are found in the forecast-report.sso file.   Apologies for not providing verbose documentation regarding that output.
SS starts the Fmsy search from the results of the F_Btarget search, so you might try a different Btarget to change the search path for Fmsy.
