Environmental quality and its impact on selective fishing — A computational perspective

Abstract

In this study, using a selective fishing model which is an application of the Penna Model, it was verified the importance of considering environmental characteristics to understand the effects of selective fishing. When subjected to the same fishing-induced mortality, populations exploited in environments with greater resource availability experience lower selective pressure, resulting in less severe deleterious effects compared to those observed in environments with lower resource availability. This result draws attention to the need for fisheries management programs to consider environmental quality so that appropriate strategies can be defined for each aquatic environment.
