This paper provides an analysis of technical and economic interrelationships among species harvested in Hawaii’s pelagic longline fishery. The results indicate that this multispecies fishery is characterized by a joint production process, meaning that the regulation of one species would affect the harvest of other species. It implies that a single species regulation may not be appropriate in ma...

Climate change is expected to influence spatial and temporal distributions of fish stocks. The aim of this paper is to compare climate change impact on a fishery with other factors impacting the performance of fishing fleets. The fishery in question is the Northeast Arctic cod fishery, a well-documented fishery where data on spatial and temporal distributions are available. A cellular automata ...

This work was carried out in the Enseada da Baleia and Vila Rápida communities. Data was provided by the Co-Management Committee of the Cardoso Island State Park (PEIC) on manjuba fishery management, technique and strategies used by the fishermen, as well as locally accumulated knowledge. Based on the results, social, ecological, and economic aspects of this type of fishing were analyzed. The i...

Individual transferable quotas (ITQs) have been identified as the preferred management tool for Commonwealth fisheries (Commonwealth of Australia 1989). This paper compares the effectiveness of ITQs as a management control with the current system of input controls in the northern prawn fishery using an integrated biological and economic model of the fishery, embedded in a stochastic optimisatio...

An agent–based bioeconomic fishery model was developed to assist in the design and evaluation of management instruments in an input controlled fishery. The agent–based structure of the model enables the choice of management instruments to be tailored specifically to account for the competitive ‘race to fish’ behavior observed in input controlled fisheries. The optimal season length and capital ...

As a legacy of Namibia’s colonial past, the country inherited severely depleted fish resources at the time of independence. Today, Namibia’s fisheries are almost exclusively industrial. The hake fishery is the country’s most important fishery, which was restructured from a pre-independence foreign fishery into one that is characterized by locally based, vertically integrated fishing and process...

Vietnam’s coastal waters feature high bio-diversity and rich fishery resources. The selected study site, Nha Phu Lagoon is characterized by massive degradation of coastal fishery resources. As a result rural livelihoods in coastal communities are threatened. Since households in these communities not only depend on coastal resources but also have various other forms of income outside the fishery...

the poor performance of fishery subsector is most clearly evidenced by low adoption of fishery production technologies by farmers. the purpose of this research was analyzing influence of socio-economic factors on the adoption of fish production technologies by community-based farmers in cross river state, nigeria. a multistage random sampling technique was used in selecting 60 community-based f...

Fishery-management policies based on the allocation of exclusive fishing rights, territorial use rights, and sea zoning are recurrent tools for achieving sustainability. In Chile, the 1991 Fishery and Aquaculture Law reformed division of the right to fish between the artisan and industrial subsectors, introduced sea-zoning (spacebased) strategies, and established a differential individual trans...
