Sammendrag
This study presents a multispecies stochastic model. The model suggests optimal fishing policy for
two species in a three species predator prey ecosystem in the Barents Sea. We have employed
stochastic dynamic programing to solve a three dimensional model, where catch is optimized by a
multispecies feedback strategy. Application of the model in cod, capelin and herring ecosystem in the
Barents Sea shows that the optimal catch for stochastic interaction model is more conservative
compared to deterministic policy. Furthermore, we found that stochasticity has strong effect on
optimal exploitation policy in the prey (capelin) compared to the predator (cod) species.
