“…In the analysis of marine reserves, many economists have pointed to this fact (Holland and Brazee, 1996), and also shown that perfectly applied private property management without reserves will better take care of both stocks and harvests, unless marine reserves are exceedingly large (Hannesson, 1998). It is clearly not fair to assume that in fisheries with a high degree of sophisticated management, the implementation of marine reserves will eradicate all other management except perhaps access (see references to limited-entry management and marine reserves below).…”

“…The advantages of reserves for commercial fisheries are usually presented as the increased fish production migrating out of reserves. The norm has been to focus on some form of density dependent dispersal in the economic literature (Hannesson, 1998, Sanchirico and Wilen, 1999) but also to some degree in the biological literature (Hastings and Botsford, 1999). But, as Gell and Roberts (2003) point out, very little is known regarding density dependent dispersal.…”

This paper gives an overview of bioeconomic modelling of marine reserves, and illustrates how economists have responded to the modelling results found in the ecological literature. The economic analysis is shown to be far more pessimistic with regard to the potential of marine reserves as a fisheries management tool, than what one finds in the purely ecological analysis, the reason being the latter's neglect of issues such as discounting and economic incentive behaviour. However, the economic analysis, despite some of it being relatively advanced with regard to spatiality, is still simplistic with regard to for instance ecosystem and habitat content. A simple expansion of the existing bioeconomic models with regard to positive habitat effects of area closures is presented and analysed, showing room for improved results from marine reserve implementation as compared to existing analysis.

“…Despite the growing interest in marine reserves both the economic benefits and the conservation impact of marine reserves have recently been questioned [23]. Dixon [24] observed that the objectives of creation of a marine reserve area can lead to conflicts between the various economic agents involved with the area.…”

This paper describes a prey-predator type fishery model with prey dispersal in a two-patch environment, one of which is a free fishing zone and other is a protected zone. The existence of possible steady states, along with their local stability, is discussed. A geometric approach is used to derive the sufficient conditions for global stability of the system at the positive equilibrium. Relative size of the reserve is considered as control in order to study optimal sustainable yield policy. Subsequently, the optimal system is derived and then solved numerically using an iterative method with Runge-Kutta fourth-order scheme. Numerical simulations are carried out to illustrate the importance of marine reserve in fisheries management. It is noted that the marine protected area enables us to protect and restore multi-species ecosystem. The results illustrate that dynamics of the system is extremely interesting if simultaneous effects of a regulatory mechanism like marine reserve is coupled with harvesting effort. It is observed that the migration of the resource, from protected area to unprotected area and vice versa, is playing an important role towards the standing stock assessment in both the areas which ultimately control the harvesting efficiency and enhance the fishing stock up to some extent.

“…The political motivation behind the introduction of marine reserves has also mainly had this focus. Recently, however, economic studies of marine reserves have shifted focus towards taking into account the economics of the fisheries as well (Holland and Brazee, 1996;Hannesson, 1998;Sanchirico and Wilen, 1999and Smith and Wilen, 2004. Hence the possibility of using marine reserves as a fisheries management tool has emerged.…”

Marine reserves: A bio-economic model with asymmetric density dependent migration

A static bioeconomic model of a marine reserve allowing asymmetric density dependent migration between the reserve and the fishable area is introduced. This opens for habitat or ecosystem differences allowing different fish densities within and outside a reserve, not Furthermore, choice of management option may also have negative consequences for long run resource use if it is incorrectly assumed that density dependent migration is symmetric.The analysis also shows that the optimal area to close, either a more or a less attractive ecosystem for the resource in question, may differ depending on the management goal.
