Inputs

• Input uncertainty Sets inputs use for the perturbation of variables
  • Groups
    • CV Coefficient of variation used for perturbation of biomass
    • Kalman weight Kalman weight used for perturbation of biomass
  • Fleets
    • CV Coefficient of variation used for perturbation of effort
    • Annual increase in catchability Amount catchability will increase each year

• Input reference levels Sets reference levels for performance evaluation and target fishing mortalities
  • MSY Uses the results a Maximum Sustainable Yield search to set Biomass limit, Biomass base and F max. for the target fishing mortalities
  • Group Evaluation of model runs has not been implemented yet so setting of reference levels has no effect
    • Biomass lower Lower biomass limit
    • Biomass upper Upper biomass limit
    • Catch lower Lower catch limit on a group
    • Catch upper Upper catch limit on a group
  • Fleet
    • Lower Lower catch limit by a fleet
    • Upper Upper catch limit by a fleet

• Input regulatory Sets inputs used for the fisheries regulations
  • Regulatory option Sets how the effort of a fleet will be regulated
    • Max effort Not implemented at this time. Caps the effort of a fleet no matter what regulatory option has been chosen
    • Not used No regulation will be used for this fleet
    • Effort Warning has not been tested or validated. Effort is regulated by computing target fishing mortality using Biomass limit, Biomass base and F max. from estimated biomass. If target fishing mortality exceeds achieved fishing mortality fishing effort is scaled back.
    • Weakest Stock quota Quota for the year is computed from Biomass limit, Biomass base and F Max using estimated biomass. Effort is regulated if any catch (landings + discards) on a group exceeds its quota.
    • Strongest stock + discards quota Quota for the year is computed from Biomass limit, Biomass base and F Max using estimated biomass. Effort is regulated if landings on the strongest stock exceed the quota. Bycatch on other stocks is discarded.
    • Selective fishing quota still needs explanation
  • Fleet Quotas Quota by group and fleet used to compute fleet share of quota on a group.
  • Target fishing mort policy Sets parameters for target fishing mortality. Biomass limit Biomass base and F max.
  • Fixed escapement Sets fixed escapement biomass of a group. If this value is set then the quota for the year is computed as [estimated biomass] - [fix escapement] instead of using the target fishing mortality parameters.
• Input effort tracking Sets weights used when evaluating current Ecosim scenario.
  • Objectives weights
  • Ecological weights
  • Fleet weights
