  Citation × Citation Citation Abstract Copy Title: Fishing in a Shallow Lake: A Case for Effort Controls? Author: Janmaat, John, Ruijs, Arjan In many situation, fishing activity adversely impacts the state of the marine ecosystem, impacts which feed back to affect fish stocks. Some ecosystems appear to have multiple equilibria and exhibit hysteresis, whereby they can become stuck in low productivity states. We show how adding ecosystem dynamics to a classic fisheries model can introduce hysteresis impacts, impacts that affect both the evolution of the fish stock and the fishery harvesting it. We demonstrate that harvest and effort taxes are not equivalent instruments for controlling this externality. We also show that if the fishery is sufficiently degraded, it may not be optimal to move the system back to a healthy environment. Title: Fishing in a Shallow Lake: A Case for Effort Controls?

  Citation × Citation Citation Abstract Copy Title: Implications of bycatch reduction strategies for the economic viability of mixed fisheries Author: Thebaud, Olivier, Martinet, Vincent There is growing recognition worldwide that the impacts of fishing on non-targeted components of marine ecosystems should be included in the assessment of fisheries sustainability. This leads to the inclusion of new constraints in evaluations of the long-term bio-economic performance of fisheries. In this paper, we analyze the implications of such constraints based on the case of bycatch of juvenile hake in the Bay of Biscay (ICES area VIIIa,b) trawl fishery for nephrops. The analysis is based on a discrete time model of the trawl fishery including an age-structured representation of stock dynamics, with uncertainty. We define sustainability using the viability framework of analysis: viability objectives are represented as constraints which relate to the economic status of the fishing fleet and to the biological status of fish stocks. We include an ecological constraint defined as a minimal target threshold for the recruitment of mature hakes, which is related to the fishing mortality induced by trawlers on juvenile hake. Based on stochastic analysis, we define the probability that both economic and ecosystemic constraints are met, as a function of the level of these constraints. We use the model to assess the sustainability of the fishery under different scenarios as regards bycatch reduction strategies.

  Citation × Citation Citation Abstract Copy Title: Tev (total Economic Value) Analysis of A Marine Environment in Norway Author: Kahui, Viktoria, Armstrong, Claire, Aanesen, Margrethe The push for ecosystem based management has opened up not only for including more of the natural systems when managing fish resources, but also a broader perspective on the human systems, and the diverse activities in the sea. This is reflected for instance in the EU Maritime Policy where fisheries is just one of many activities that marine management must take into account. Research into valuation of natural resources has shown that non-use values may be substantial in the marine environment; These are e.g. existence values, such as the existence of rare species and benthic components such as corals, and option values with regard to potential future applications, e.g. in marine bioprospecting. In addition, indirect use values, such as habitat values, recreational values and nutrient cycling often far exceed the direct use values, which are typically the value of the fisheries, aquaculture and marine tourism. Applying and critiquing the Total Economic Value (TEV) set up, we have estimated marine direct use values, including fisheries and aquaculture, indirect use values and non-use values in Nordland county in Norway, specifically connected to the Lofoten-Vesterålen marine area. Lofoten-Vesterålen is the most important spawning ground for commercial fish resources such as cod and herring, and it is also a very popular tourist destination. Yet when studying some of the other values that the marine environment supplies, these traditional values are not necessarily the most important.

  Citation × Citation Citation Abstract Copy Title: Nutrient Enrichment and Marine Ecosystem Disturbance: A Deterministic and Stochastic Approach Author: Knowler, Duncan Year: 2001 Pollution of the marine areas that support much of the world's commercial fisheries is regarded as a pressing global environmental problem. One often-cited issue is nutrient enrichment, but this may be a mixed blessing: it contributes to primary productivity and increases the sustainable fish catch, while simultaneously causing occasional and damaging ecosystem events. Thus, enrichment's aggregate impact on the economic value of fisheries may be ambiguous. This research develops a method for analyzing such problems, using the example of the Black Sea anchovy fishery. Employing a bioeconomic model that incorporates nutrients directly into fish population dynamics, the problem is formulated in deterministic and stochastic terms and the results compared. The deterministic model assumes that nutrients only contribute positively to fish production for a given ecological state, and ignores stochastic events leading to shifts between states. Accordingly, marginal abatement of nutrients leads to annual welfare losses of US$ 45,000 to 713,00 per μ (1989/90 prices), depending upon the ecosystem state. The stochastic formulation recognizes that planners may have some knowledge of potentially damaging shifts in ecological states, and wish to take this into account. When these shifts are related stochastically to the level of enrichment, nutrient abatement is shown to have an indeterminate welfare effect. However, an experimental empirical analysis indicates that a marginal change in nutrients can generate positive and sizeable aggregate benefits for the Black Sea anchovy fishery under certain conditions. The general applicability of such an approach for analyzing a range of marine environmental problems is noted Title: Nutrient Enrichment and Marine Ecosystem Disturbance: A Deterministic and Stochastic Approach Author: Knowler, Duncan Year: 2001 Pollution of the marine areas that support much of the world's commercial fisheries is regarded as a pressing global environmental problem.

  Citation × Citation Citation Abstract Copy Title: Aquaculture and Food Security - Can Fish Farming Fill the Gap? Author: Troell, Max While aquaculture has provided economic and nutritional benefits to millions, there are concerns that unconstrained sector expansion and intensification, coupled with its ecological and social impacts, globalization of markets, and climate change, may have undesirable impacts on the resilience of social-ecological systems. A significant part of the aquaculture expansion is expected to occur in coastal areas, where it directly affects resource systems already experiencing large pressure from human activities. Thus, there is a risk that the anticipated benefits from aquaculture may come at the expense of increased pressure on coastal ecosystem services, thus jeopardizing coastal people’s food security and livelihoods. Further, intensification may also indirectly increase the dependence on marine ecosystems through usage of fish resources as feeds. The practice of intensive farming of fish and crustaceans is characterised by inputs of high quality resources and energy and release of effluents. The industry continues to improve performance through research on food development and system designs, and recent initiative, the “Aquaculture dialogue”, attempts to identify sustainability criteria for a selection of cultured species. In addition FAO have recently moved beyond their earlier established “code of conducts” and are now developing a broader systematic perspective on aquaculture, i.e. “Ecosystem approach to aquaculture”. This presentation will discuss how aquaculture may impact on social-ecological resilience, more broadly and also in connection to coastal aquaculture development, and specifically considers the intensification of production methods. In connection to this some recent sustainability tools/indicators will briefly be discussed out from this perspective. Title: Aquaculture and Food Security - Can Fish Farming Fill the Gap?

  Citation × Citation Citation Abstract Copy Title: An Elemental Basis of Property Rights to Marine Fishery Resources Author: Edwards, Steven F. Year: 2001 Among the questions that ecosystem-based management raises for economists is how to partition uses of the many biological, chemical and physical attributes of marine ecosystems into sets of property rights that undergird total ocean wealth. An elemental basis of property rights for fisheries involves the interplay between ecological and technological interactions, including sideeffects (externalities), and transaction costs. Fisheries management typically divides ownership by species. Divided ownership is efficient where production requires specialized skills and technologies and/or where interactions are negligible. When damages caused by side-effects are substantial, divided ownership might be used either by attenuating (e.g., gear restrictions) or excluding (e.g., zoning) a subset of attribute rights, provided that the opportunity (reduced output) and transaction costs of restrictions/exclusions are less than damages in their absence. However, uncertainty about resource dynamics, the recurrent nature of interactions, the complexity of numerous contractual stipulations owing to multi-attribute resources, and practical enforcement problems make it likely that the transaction costs of divided ownership are great at this time. Alternatively, property rights could be bundled into sets wherein tradeoffs across margins which promote the total wealth of a multi-attribute, common pool asset would be decided internally by a governance organization. Bundled sets of property rights influence the choice of organizational structures (government agency, commons, unitization of firms) and contracts (fishery management plans, rules, private contracts). The discussion is illustrated with examples from U.S. fisheries in the Northeast Region. Title: An Elemental Basis of Property Rights to Marine Fishery Resources Author: Edwards, Steven F.

  Citation × Citation Citation Abstract Copy Title: A Proposed Framework for Identifying and Evaluating Ecosystem Service Tradeoffs for Marine Protected Area Planning Author: Harte, Michael, Heppell, Selina, Rosenberger, Randall, Sylvia, Gil Existing research on the effectiveness of marine protected areas narrowly focuses on developing sets of management indicators tied to outcomes described in management plans or on the achievement of a single objective such as an increase in the size or number of older, more fecund female fish in a protected area. These approaches, however, fail to capture the dynamic complexity of social, cultural, economic and ecological processes, uncertainty, and tradeoffs associated with the establishment and operation of marine protected areas. Moreover, there is usually little recognition of local coastal communities, including fishing communities, and the values they hold in the evaluation of the relative benefits and costs of marine protected areas. We describe a framework for evaluating and assessing economic and ecosystem tradeoffs associated with marine protected areas and other forms of marine spatial planning. This framework integrates biophysical data and community-based social and economic evaluation methods. It identifies ecosystem services, their benefits and associated uncertainties in assessing the economic and social tradeoffs associated with changes in the use of the marine environment.
