dc.description.abstract | The multispecies fisheries management looks at a bigger picture in addressing the long-term
consequences of present decisions. This implies an ecosystem management that includes a
number of species and their physical, biological and economic interactions. These interactions
make the growth of resources stochastic and increase complexity in understanding stock
dynamics and optimal catch for such a stochastic and multiple stocks´ system. To address the
issue of identifying optimal catch of stochastically growing multi stocks, we have formulated and
applied a time-continuous stochastic model. The model contributes to multispecies bioeconomic
management of marine ecosystems. An application of model in a predator-prey relationship in
Barent Sea revealed that the optimal catch for stochastically growing stocks in a multispecies
interaction model is different from the deterministic model. | no_NO |
