    44  A video tutorial has been created to demo the alpha version of the MSE.  This video can be found [http://files.me.com/ecopath/wfeu0p.mov here].

    6 == How the model runs == 
    7 The MSE is capable of running two types of management procedures. Target fishing mortality and Fixed escapement  
     6== How to run the MSE == 
     7Set Quotas 
     8 
     9  The MSE is capable of setting quotas by two methods. Target fishing mortality rates and Fixed escapement. Target fishing mortalities are set via the '''Input regulatory '''> '''Target fishing mortality''' dialogue then setting biomass limit, biomass base and F max. values for individual groups. Fixed escapement values are set via the '''Input regulatory '''> '''Fixed escapement''' dialogue. If fixed escapement is provided the yearly quotas will be calculated as the biomass greater than the fixed escapement. Otherwise quotas will be calculated from the target fishing mortality rates.

     12 
     13        How quotas are implemented is set via the '''Input regulatory''' > '''Regulatory options''' dialogue. Four options are provided  
     14 
     15   1. '''Not Used '''no regulation will be imposed on this fleet.

    920The MSE is capable of running in three different modes. 
    1021 
    11 '''Ecosim effort use regulatory options Using fishing effort from the currently load Ecosim scenario then regulating fishing effort when fishing mortality exceeds target values set via the Target fishing mortality form.''' 
     22'''Ecosim effort use regulatory options '''Using fishing effort from the currently load Ecosim scenario then regulating fishing effort when fishing mortality exceeds target values set via the Target fishing mortality form. 
    1223 
    13 '''Predict effort use regulatory options '''Predicting fishing effort based on the parameters set in the Fleet size dynamics then regulating fishing effort when fishing mortality exceeds target values set via the Target fishing mortality form. 
     24'''Predict effort use regulatory options '''Predicting fishing effort based on the parameters set in the Fleet size dynamics then regulating fishing effort when fishing mortality exceeds target values set via the Target fishing mortality form. 
    1425 
    1526Evaluating the currently load Ecosim scenario. No attempt is made to regulate the fishery this mode is strictly an evaluation of the current Ecosim scenario. 
     
    3748   * '''Regulatory option''' Sets how the effort of a fleet will be regulated. 
    3849     * '''Not used''' No regulation will be used for this fleet. 
    39      * '''Weakest Stock quota''' Quota for the year is computed from the target fishing mortalities using a perturbed biomass. Effort is regulated if any catch (landings + discards) on a group exceeds its quota. 
    40      * '''Strongest stock + discards quota''' Quota for the year is computed from the target fishing mortality using a perturbed biomass. Effort is regulated if landings on the strongest stock exceed the quota. Catches that exceed the quota are discarded. 
    41      * '''Selective fishing quota''' Quota for the year is computed from the target fishing mortality using varied biomass. Effort is regulated if landings on the strongest stock exceed the quota. 
    42    * '''Fleet Quotas''' Quota by group and fleet used to compute fleet share of quota on a group. 
     50     * '''Weakest Stock quota'''  Effort is regulated if any catch (landings + discards) on a group exceeds its quota. 
     51     * '''Strongest stock + discards quota''' Effort is regulated if landings on the strongest stock exceed the quota. Catches that exceed the quota are discarded. 
     52     * '''Selective fishing quota''' Effort is regulated if landings on the strongest stock exceed the quota. 
     53   * '''Fleet Quotas''' Quota by group and fleet used to compute a fleets share of the quota on a group. 
    4354   * '''Target fishing mortality''' Sets parameters for target fishing mortality. Biomass limit, Biomass base and F max. 
    4455   * '''Fixed escapement''' Sets fixed escapement biomass of a group. If this value is non zero the quota for the year is computed as [estimated biomass] - [fix escapement] instead of using the target fishing mortality parameters. 
     
    5061 * '''Run MSE''' Run the Management Strategy Evaluation. 
    5162   * '''Effort and regulatory options''' Options used to set how or if the fishery is regulated during the current evaluation. 
    52      * '''Ecosim effort use regulatory options''' Ecosim is run using effort from the current scenario. The fishing effort is then regulated according to the target fishing mortality and the options selected in the '''Regulatory options''' dialogue. 
    53      * '''Predict effort use regulatory options''' Fishing effort for the year is predicted using the Ecosim Fleet/effort dynamics model. The fishing quota for each year is then set via the target fishing mortality. The fishing effort is then regulated according to the options selected in the '''Regulatory options''' dialogue. 
    54      * '''Ecosim effort no regulations(evaluates current 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. 
     63     * '''Ecosim effort use regulatory options''' Ecosim is run using effort from the current scenario. The fishing effort is then regulated according to the target fishing mortality and the options selected in the '''Regulatory options''' dialogue. 
     64     * '''Predict effort use regulatory options''' Fishing effort for the year is predicted using the Ecosim Fleet/effort dynamics model. The fishing quota for each year is then set via the target fishing mortality. The fishing effort is then regulated according to the options selected in the '''Regulatory options''' dialogue. 
     65     * '''Ecosim effort no regulations(evaluates current 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. 
    5566   * '''Model run options''' 
    5667     * '''Save output''' Saves output for biomass, catch by group, catch by fleet and effort by fleet to a csv file in a sub directory of the current EwE6.exe called MSE.
