Abstract The benefits of physiological biomarkers, knowledge and concepts are well-established in fish wildlife management as they confer the ability to understand mechanistic processes, identify cause-and-effect relationships, develop predictive models. Although this approach is gaining momentum context species conservation, use biomarkers exploited marine stock recovery plans remains relative...
There are ample data that suggest fisheries exploitation affects not only target stocks but also communities of organisms, ecological processes, and even entire ecosystems. Conservationists, and the non-governmental organizations they represent, consider such impacts a cause for concern, because the loss of biodiversity that can result is largely irreversible. Those of us who view conservation ...
Reef fisheries provide a vital source of income and food to millions of people worldwide. Reef fishes are important to many countries in the Caribbean not only for their value to the fisheries, but also their value to the tourism industry, where they are an important part of the snorkeling and diving experience. Many Caribbean reef fisheries have been overexploited for decades and often their d...
This paper presents a model for Fisheries Social Impact Assessment (SIA) that lays the groundwork for development of fisheries-focused, quantitative social assessments with a clear conceptual model. The usefulness of current fisheries SIA’s has been called into question by some as incompatible with approaches taken by fisheries biologists and economists when assessing potential effects of manag...
Co-management of natural resources involves shared management authority and responsibility between resource users or community groups at local levels and central government authorities. In data-poor, small-scale fisheries systems, community-based planning efforts can be informed by participatory research approaches that involve community members and stakeholder groups in the design, development...
In many tropical nations, fisheries management requires a community-based approach because small customary marine tenure areas define the spatial scale of management [1]. However, the fate of larvae originating from a community's tenure is unknown, and thus the degree to which a community can expect their management actions to replenish the fisheries within their tenure is unclear [2, 3]. Furth...
Recognizing that all management decisions have impacts on the ecosystem being exploited, an ecosystem-based approach to management seeks to better inform these decisions with knowledge of ecosystem structure, processes and functions. For marine fisheries in the California Current, along the West Coast of North America, such an approach must take into greater consideration the constantly changin...
Generating awareness of environmental conservation issues among the public is essential if there is an expectation of them to alter their behaviour, facilitate informed decisions and engage governments or regulatory authorities to take action. There are, however, exceedingly few public engagement success stories related to inland fishes and fisheries policy and resource allocation decisions. In...
Amidst overexploited fisheries and further climate related declines projected in tropical fisheries, marine dependent small-scale fishers in Southeast Asia face an uncertain future. Yet, small-scale fishers are seldom explicitly considered in regional fisheries management and their contribution to national fish supply tends to be greatly under-estimated compared to industrial fisheries. Lack of...
Washington. Since then the graduate student symposium has been providing a unique venue for fisheries students to meet and discuss their work, and to foster communication links between graduate students in different west coast universities and departments. This report is an attempt to disseminate the information on current research and ideas been developed by students in the different universit...
