HARVESTING STRATEGIES FOR
A MIGRATORY FISH STOCK
BASED ON A MODEL WITH UNCERTAINTY

C.S. LEE and B.S. GOH

Abstract:

We model a species of fish with breeding ground protected, and harvesting is carried out in an adjacent area. There is migration of fish from the breeding ground to the adjacent area. We demonstrate that in the presence of bounded uncertain disturbances, the strategy of harvesting the fish biomass at the maximum sustainable yield level is indeed optimal in the long term consideration.
