The sustainable yield function is a favoured tool in fisheries policy making. Normally, this function is drawn as a continuous curve in effort-yield space. This means that sustainable yield (harvest) is gradually reduced to zero as fishing effort increases. This, however, does not have to be the case. The sustainable...
Individual quota (IQ) management systems in commercial marine fisheries are highly diverse, differing in the security, durability and exclusivity of the harvesting privilege and the transferability of quota units. This diversity in the degree of harvest rights may influence the effectiveness of IQ fisheries to meet management objectives. We conducted...

The purpose of this study is aimed at developing a simple bioeconomic model of the Namibian rock lobster fishery, with the main objective being to incorporate economics into fisheries management in order to estimate the potential economic benefits that could accrue to the fishery given efficient management. The complex nature...
Most fish stocks worldwide are not optimally exploited and are therefore are producing less in biologic and economic terms that what it could be obtained. MSY objective for all the stocks by 2015 is put forward by several countries as management target to be achieved, while other countries such as...
The hilsa shad (Tenualosa ilisha) fishery is by far the largest single species fishery in Bangladesh. In this paper, a simple bio-economic year-class based model is developed to describe the fishery and examine its properties. With the help of this model, the optimum sustainable yield of the fishery is calculated...
