Fish Population Dynamic and Stock Assessment

4.1.3. Application of mortality parameters

Estimates of fishing mortality rates are often included in mathematical yield models to predict yield levels (Yield per recruit) obtained under various exploitation scenarios. These are used as resource management indices or in bioeconomic studies of fisheries.

They are used as input data in the Analytical Model of Beverton and Holt in estimating Maximum Sustainable Yield per Recruit. Further, this model predicts the effect of changes in fishing effort on future yields. In addition to the application in stock production modelling, they are also used as input data in cohort analysis, and in estimating standing stock biomass of aquatic animals.
