Stochastic optimization for multispecies fisheries in the Barents Sea
(Discussion paper;02/14, Working paper, 2014-02)
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 ...
Fisheries management under irreversible investment : does stochasticity matter?
(Discussion paper;2011:20, Working paper, 2011-11)
We present a continuous, nonlinear, stochastic and dynamic model for capital investment in the exploitation of a renewable resource. Both the resource stock and capital stock are treated as state variables. The resource ...
Analyzing risk of stock collapse in a fishery under stochastic profit maximization
(Discussion paper;2012:4, Working paper, 2012-04)
In commercial fisheries, stock collapse is an intrinsic problem caused by overexploitation or due to pure stochasticity. To analyze the risk of stock collapse, we apply a relatively simple Monte Carlo approach which can ...
Do species interactions and stochasticity matter to optimal management of multispecies fisheries?
(Discussion paper;2012:1, Working paper, 2012-01)
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, ...
Long-term sustainable and optimal management of multispecies stochastic fisheries
(Working papers;01/14, Working paper, 2014-02)
Multispecies fisheries management is the first step towards ecosystem-based fisheries management. Multispecies management accounts for a number of species and their physical, biological, and economic interactions. These ...
Harvesting in a Fishery with Stochastic Growth and a Mean-Reverting Price
(Journal article; Peer reviewed, 2014)
We analyze a continuous, nonlinear bioeconomic model to demonstrate how stochasticity in the growth of fish stocks affects the optimal exploitation policy when prices are stochastic, mean-reverting and possibly harvest ...
