AvC_MLL.Rd
A example mixed control MP that uses the average catch output control MP together with a minimul size limit set at the size of maturity.

with the TAC, Retention slot(s) populated
The average catch method is very simple. The mean historical catch is calculated and used to set
a constant catch limit (TAC). If reps
> 1 then the reps
samples are drawn from a log-normal
distribution with mean TAC
and standard deviation (in log-space) of 0.2.
For completeness, the TAC is calculated by:
$$\textrm{TAC} =\frac{\sum_{y=1}^{\textrm{n}}{C_y}}{\textrm{n}}$$
where \(\textrm{TAC}\) is the the mean catch recommendation, \(n\) is the number of historical years, and \(C_y\) is the catch in historical year \(y\).
The size of retention is set to the length of maturity.
This MP has been included for demonstration purposes of a mixed control MP.
