Several reference MPs for your operating model to use in the management strategy
evaluation. FMSYref (and related) assume perfect information about FMSY (FMSY
is taken from the operating model stored at
and set an effort limit (TAE) so that F=FMSY (or some fraction of FMSY) in
each year the MP is applied. NFref sets annual catch to zero and is used
for looking at variability in stock with no fishing.

Note that you can out-perform
FMSYref easily. The requirement for fixed
F is actually quite strict and is by no means the upper limit in terms of
yield. Don't panic if your method beats this one for yield, especially for
short-lived species of high temporal variability in productivity!
