Climate change will have a wide range of impacts on fisheries, other human uses of marine systems, and the coastal communities that depend on the ocean for their livelihoods. This presentation focuses on small-scale fisheries, providing a review of the current state of knowledge on social and economic impacts of...
A local fisheries management model employing short-term fisheries closures for rapidly growing species is proliferating across coastal east Africa and Indian Ocean islands. Aiming to improve management and boost incomes, NGOs, international finance institutions, and government agencies are promoting the technique in artisanal fishing communities. In southwest Madagascar alone, over...
Assuming a broad set of management goals, we analyze the implementation of a marine protected area (MPA) together with open access by applying a bioeconomic model that ensures unchanged growth post-MPA. Taking into account that conservation and restoration, food security, employment and social surplus are amongst the objectives that many...
This paper shows that the importance of fish habitat depends in part on the management of the fishery. Two cases of cold water coral - fisheries interactions are studied in a bioeconomic model setting: Norwegian and Icelandic redfish fisheries. The two countries have applied different types of management; Norway’s management...
We introduce a modified version of the standard Gordon-Schaefer fishery model. Standard theoretical models usually treat fishing effort as an aggregate measure encompassing all different types of inputs. Consequently, these models do not enable us to examine the problem of fleet redundancy and capital stuffing separately, i.e. two ways in...
In 2010, the New England Groundfish fishery adopted a sector-based management plan, wherein self-identifying groups of harvesters are allocated their collective total share of the harvest of each species as a group right, that they may manage in any way they wish. This means a single fishery with a single...
Quotas or permits are frequently used in the management of renewable resources and emissions. However, in many industries there is concern about the basic effectiveness of quotas due to noncompliance. We develop an enforcement model of a quota-regulated resource and focus on a situation with significant non-compliance and exogenous constraints...
Human-induced changes in life-history traits have been observed for many harvested populations, with a component of those changes being attributed to an evolutionary (i.e., genetic) response. Most notably, fish stocks that experience high fishing mortality show a tendency to mature earlier and at a smaller size. Some have suggested that...
Farmer-to-farmer extension approach was introduced for small-scale freshwater aquaculture development in the seven provinces of the southern Benin in the course of a technical cooperation project of Japan. Firstly, some relatively active and capable fish farmers were selected and trained together with extension officers of the government to be "core...
