    1111  How quotas are implemented is set via the '''Input regulatory''' > '''Regulatory options''' dialogue. Four options are provided 
    1212 
    13   Not Used. No quota regulation will be imposed on this fleet.  
    14   Weakest stock + discards quota. If catch on any group exceeds its quota then effort will be limited at that level.  
    15   Strongest stock. If catch of the group with the maximum effort exceeds its quota then effort will be limited. Catch in excess of quota is discarded and will have a discard mortality set via  '''Input data''' > '''Fishery '''> '''Discard mortality rate'''. 
    16   Selective fishing quota. If catch of the group with the maximum effort exceeds its quota then effort is limited. Catch in excess of quota will not be included in the fishing mortality and will be assumed to have a 100% discard survival rate. 
     13   1. Not Used. No quota regulation will be imposed on this fleet.  
     14 1. Weakest stock + discards quota. If catch on any group exceeds its quota then effort will be limited at that level.  
     15 1. Strongest stock. If catch of the group with the maximum effort exceeds its quota then effort will be limited. Catch in excess of quota is discarded and will have a discard mortality set via  '''Input data''' > '''Fishery '''> '''Discard mortality rate'''.  
     16 1. Selective fishing quota. If catch of the group with the maximum effort exceeds its quota then effort is limited. Catch in excess of quota will not be included in the fishing mortality and will be assumed to have a 100% discard survival rate.

    1820==== Run the MSE ==== 
    1921  The MSE is capable of running in three different modes. 
    2022 
    21   Ecosim effort use regulatory options. Uses fishing effort from the currently loaded Ecosim scenario then regulates effort according to the regulatory options selected. When using this option make sure you have set Ecosim effort high enough for catches to exceed the quota or the regulatory option will never come into effect. Also if catches go to zero this option will keep effort at the Ecosim input levels. It will never reduce the effort because there was no catch. 
     23   1. Ecosim effort use regulatory options. Uses fishing effort from the currently loaded Ecosim scenario then regulates effort according to the regulatory options selected. This option will only reduce the effort if catches exceed the quota. You may need to increase the Ecosim effort to see any effect of this option. Also if catches go to zero this option will keep effort at the Ecosim input levels. It will never reduce the effort because there was no catch. 
     24 1. Predict effort use regulatory options. Fishing effort will be predicted based on the parameters set in the '''Fleet size dynamics''' form then fishing effort will be regulated according to the regulatory options selected. 
     25 1. Evaluating the currently load Ecosim scenario. No attempt is made to regulate the fishery this mode is used to evaluate the current Ecosim scenario. 
    2226 
    23   Predict effort use regulatory options. Predicting fishing effort based on the parameters set in the Fleet size dynamics then regulating fishing effort according to the regulatory options selected. 
    2427 
    25   Evaluating the currently load Ecosim scenario. No attempt is made to regulate the fishery this mode is strictly an evaluation of the current Ecosim scenario.
