Fish Population Dynamic and Stock Assessment

6.1.3. Surplus production model

This model does not take into account age and growth. Hence, it could be safely applied to tropical stocks, where calculation of age of tropical fish is more cumbersome.

When catch and effort data are applied for a number of years, the MSY thus generated will be more meaningful for sustainable fishery.

The two models will be highlighted in this chapter.

1. Schaefer model

2. Fox model
