Creator:: Kimoto, Ai and Matsuishi, Takashi
Abstract:: Unfortunately, most of the stocks are damaged by natural disasters or human activities and rebuilding the stock are urgent requirements. Until now, in the stock management, some policies are commonly believed to valid but have not been confirmed. A simulation model of the population dynamics incorporating uncertainty has been already...

Creator:: Idels, Lev V. and Ou, Beiyan
Abstract:: We study the combined effects of periodically varying carrying capacity and survival rates on the fish population in the ocean (sea). We introduce a new delay differential equation model with a control parameter which describes how fish are harvested. We consider a predation function as the function of the delayed...

Creator:: Skonhoft, Anders
Abstract:: This paper formulates a simple biomass growth model of a fishery. The property rights regime is of the unregulated local common property type with a fixed number of fishermen and where the fish stock is exploited in a myopic profit-maximizing manner. Within this resource management setting it is demonstrated that...

Abstract:: The Northern Prawn Fishery is one of the most valuable fisheries in Australia with a yearly estimated value of production of about $64mil. Nine prawn species are commercially harvested from the Northern Prawn Fishery with 80% of annual average catch represented by the banana prawn (Fenneropenaeus merguiensis) and the tiger...
