Making Landfall: Linkages between Fishing Communities and Support Services

The relationship between the fishing industry and the fisheries-related support service sector creates economic benefits for communities through the strong linkages between fishermen and their land-based suppliers and the induced or multiplier effects from fisheries revenue. The support service sector is embedded within fishing communities where the impacts of fisheries management changes are perpetuated. This article examines the potential for such impacts by evaluating the diversity of fishing gear use, ex-vessel revenue, presence of processing plants, public moorage, and haul-out or tidal grids, and the number of vessels in a community, in relation to the availability of support services in communities in Alaska. The results show that the presence of a processor and haul-out facilities in a community significantly affects the number of support service businesses; however, there is not a strong association with the number of vessels or ex-vessel revenue. One hypothesis is that fishermen often travel to other communities to obtain services. We evaluate this hypothesis using social network analysis to evaluate transfers of revenue for fishery-related goods and services. Ultimately, this informs the exploration of the importance of support service businesses and fishery-support infrastructure to the continued well-being of fishing communities.

Application of a Sustainable Fisheries Development Indicator System (SFDIS) for Better Management Outcomes in Taiwan Offshore and Coastal Fishery

A sustainable fisheries development indicator system (SFDIS) is proposed in this article to monitor management of Taiwan's offshore and coastal fisheries. Demonstration of its application shows that the ecological index is tending toward sustainability but to conserve fisheries’ resources it is necessary to strengthen habitat protection and management through a partnership approach. The economic index is tending toward unsustainability as a result of a decline in fisheries’ Gross Domestic Product (GDP), value, economic production, and investment. An aging fisherman population and decreasing social performance and resilience contribute to unsustainability of the social index. By contrast, the institutional index is sustainable because of improved management efficiency, ability, and capacity-building. However, some problems exist with regard to compliance and acceptability of institutional expense. Overall, the SFDIS suggests that an increase in employee number, incorrect statistical data, and unacceptable institutional expense will make Taiwan's offshore and coastal fisheries unsustainable in the long run.     

Estuary Management and Recreational Fishing Benefits

Recognition of the benefits to society supported by estuary ecosystem functions and services, and threats to these benefits posed by human activities, has led to various public programs to restore and protect estuaries at the federal, state, and local levels. As available budgets shrink, program administrators and public elected officials struggle to allocate limited restoration and protection funds to the highest priority areas. Economic benefit and cost information can provide useful inputs into this decision-making process by quantifying estuary restoration and protection benefits and costs in commensurate terms. In this paper, a combined actual and intended travel behavior model is described that can be applied to estimate the recreational fishing benefits of estuary restoration and protection. The model was estimated for recreational fishing in the Lower Atchafalaya River Basin estuary along the Gulf of Mexico, Louisiana, USA coast. Changes in freshwater flows into this estuary may affect redfish and speckled trout game fish populations. The model indicates that changes in catch rates of these two species would have a relatively minor affect on annual fishing trips per angler. However, because total effects may be large when effects per angler are aggregated across total anglers, resource management agencies should consider these changes in recreation benefits when evaluating projects that influence the ecology of coastal estuaries, fish populations, and catch rates. Moreover, in other coastal areas or situations, the responsiveness of angling trips to changes in catch rates may vary because of differences in user populations, environmental conditions, fish populations, and fishing experiences.     

日本韩国海洋捕捞渔船发展概况

日本和韩国均为渔船制造业和海洋捕捞业发达的国家。本文根据渔船数量、吨位、功率(马力)、材质和渔船种类等多项统计数据,分析了近10余年日韩两国海洋捕捞渔船的变化情况及发展特点,探讨了两国在渔船管理方面的法规、措施及存在的问题,以及两国的管理经验对我国渔船管理的启示。数据表明,日韩两国的海洋渔船减船效果明显,并基本实现了渔船材质玻璃钢化;分析认为,日韩两国在渔船管理方面的法规建设及相关管理实践对我国的现代渔船业发展及海洋捕捞“双控”管理具有一定的借鉴意义。
