Do Species Interactions and Stochasticity Matter to Optimal Management of Multispecies Fisheries?
Poudel, Diwakar; Sandal, Leif Kristoffer; Steinshamn, … - 2012
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...

Optimal Fishing Mortalities with Age-Structured Bioeconomic Model - A Case of NEA Mackerel
Ni, Yuanming - 2016
The effects of random environmental impacts on optimal exploitation of a fish population are investigated using both optimization and simulation, based on a discrete-time age-structured bioeconomic model. The optimization problem is solved as a non-linear programming problem in GAMS. First, a...

Fisheries Management Under Irreversible Investment : Does Stochasticity Matter?
Poudel, Diwakar - 2011
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 owner controls fishing effort and the investment rate in an optimal way....
