v18 v19 5 5 6 6 == How to run the MSE == 7 Set Quotas 7 ==== Set Quotas ==== 8 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. 8 9 9 The MSE is capable of setting quotas by two methods. Target fishing mortality rates and Fixed escapement.

Otherwise quotas will be calculated from the target fishing mortality rates. 10 ==== Set regulatory option ==== 11 How quotas are implemented is set via the '''Input regulatory''' > '''Regulatory options''' dialogue. Four options are provided 10 12 11 Set regulatory option 13 '''Not Used - No quota regulation will be imposed on this fleet.[[BR]]'''Weakest stock + discards quota - If catch on any group exceeds its quota then effort will be capped at that level. 14 Strongest stock + discards quota - If catch of the group with the maximum effort exceeds its quota then effort is capped and the excess catch will be discarded. 15 Selective fishing quota - 12 16 13 How quotas are implemented is set via the '''Input regulatory''' > '''Regulatory options''' dialogue. Four options are provided 17 ==== Run the MSE ==== 18 The MSE is capable of running in three different modes. 14 19 15 1. '''Not Used '''no regulation will be imposed on this fleet.16 1. '''Weakest stock + discards''' '''quota '''if the catch of any group fished by a fleet exceeds its quota the effort for that fleet will be capped and the20 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.''' 21 17 22 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.''' 24 18 25 19 20 The MSE is capable of running in three different modes. 21 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. 23 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. 25 26 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. 26 Evaluating the currently load Ecosim scenario.

Catches that exceed the quota are discarded. 52 * '''Selective fishing quota''' Effort is regulated if landings on the strongest stock exceed the quota. 53 53 * '''Fleet Quotas''' Quota by group and fleet used to compute a fleets share of the quota on a group. 54 54 * '''Target fishing mortality''' Sets parameters for target fishing mortality. Biomass limit, Biomass base and F max.
