v45 v46 15 15 ''MSE Quota controls form.[[BR]]''[[Image(MSE_Quota_Controls.jpg)]] 16 16 17 18 19 17 * '''Cap effort at:''' caps the effort needed to achieve the fishing mortality or quota. 18 * '''Cap effort at Ecosim level:''' fishing effort can never exceed level set by current Ecosim scenario 19 * '''Predict effort: '''effort is predicted by the Ecosim Fleet/effort dynamics model then cap so as not to exceed the regulatory rules. 20 20 21 * '''No quota:''' no regulation will be used for this fleet. 22 * '''Weakest stock quota + discards quota:''' effort is regulated if any catch (landings + discards) on a group exceeds its quota. 23 * '''Highest value stock quota:''' effort is regulated if landings on the highest value stock exceed the quota. Catches that exceed the quota on a stock are discarded. 24 * '''Selective fishing quota:''' Effort is regulated if landings on the strongest stock exceed the quota. 21 25 22 * '''No quota:''' no regulation will be used for this fleet.23 * '''Weakest stock quota + discards quota:''' effort is regulated if any catch (landings + discards) on a group exceeds its quota.24 * '''Highest value stock quota:''' effort is regulated if landings on the highest value stock exceed the quota. Catches that exceed the quota on a stock are discarded.25 * '''Selective fishing quota:''' Effort is regulated if landings on the strongest stock exceed the quota.26 27 [[BR]]28 26 * '''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. 29 27 30 31 32 28 * '''Catch/estimated biomass:''' Fishing mortality is estimated using a perturbed biomass then effort is updated using the varied fishing mortality. 29 * '''Direct exploitation:''' Fishing mortality is computed directly from the predicted Ecosim catch 30 * '''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. 33 31 34 32 = =
