Population viability analysis (PVA) is a method to evaluate the probability of an unexpected state (e.g. extinction, decline population) as a function of several biological and environmental variables. In fisheries science there is not consensus in the way to implement the PVA, which has covered from qualitative model-free approach to sophisticated mathematical frameworks including spatially explicit and stochastic models. In this work I will expose some ideas about the application of PVA in fisheries science using a probabilistic and mathematical approach. PVA method such shown here accounts and compares the multi-criteria decision problem underlying fisheries management.
