    1010 * '''Use regulatory controls:''' evaluate the regulatory rules. 
    11   * '''Use input effort controls (linear programming solution):''' uses a linear programing algorithm to find a fishing effort that meets the fishing mortality constraints and is optimised for the total value of the catch. When this control option is selected you can set the upper and lower fishing effort bounds for each fleet.

    13 ''MSE LP controls form.[[BR]]''[[Image(MSE_LP_Controls.jpg)]] 
    14  
    15   * ''''Use output (quota) controls:'''' fishing effort is set at the level required to meet fishing mortality or quota set via the regulatory rules i.e. Target fishing mortality, Fixed F, Escapement or TAC. When this option is selected you can set the maximum fishing effort and quota control implementation methods.

    1915  * '''Cap effort at:''' caps the effort needed to achieve the fishing mortality or quota. 
    2016  * '''Cap effort at Ecosim level:''' fishing effort can never exceed level set by current Ecosim scenario 
    2117  * '''Predict effort: '''effort is predicted by the Ecosim Fleet/effort dynamics model then cap so as not to exceed the regulatory rules. 
    22  
    2318  * '''No quota:''' no regulation will be used for this fleet. 
    2419  * '''Weakest stock quota + discards quota:''' effort is regulated if any catch (landings + discards) on a group exceeds its quota. 
    … …  
    2722 
    2823 * '''No regulatory controls (evaluate the current Ecosim scenario):'''Ecosim is run using effort from the current scenario. No attempt is made to regulate the fishing effort. This option is used to evaluate the current Ecosim scenario.

    32  * '''Catch/estimated biomass:''' Fishing mortality is estimated using a perturbed biomass then effort is updated using the varied fishing mortality. 
    33  * '''Direct exploitation:''' Fishing mortality is computed directly from the predicted Ecosim catch 
    34  * '''Exact biomass known:''' Fishing mortality is computed directly from the predicted Ecosim catch and biomass. Effort is then update with the predicted fishing mortalities and perturbed before use. 
     25  * '''Catch/estimated biomass:''' Fishing mortality is estimated using a perturbed biomass then effort is updated using the varied fishing mortality. 
     26  * '''Direct exploitation:''' Fishing mortality is computed directly from the predicted Ecosim catch 
     27  * '''Exact biomass known:''' Fishing mortality is computed directly from the predicted Ecosim catch and biomass. Effort is then update with the predicted fishing mortalities and perturbed before use.
