Limitations of the Korean conventional fisheries management regime and expanding Korean TAC system toward output control systems

In this paper, we focus on the status and trends of the current Korean fisheries management regime. Specifically, this paper briefly introduces the Korean conventional fisheries management regime (KCFMR) and discusses its problems and limitations. In describing policy evolution, this paper finds reasons why the Korean government has chosen a TAC system, an output control approach, besides input control approaches in force for almost a century. This paper also describes the evolution of the Korean TAC system, which is carrying out a pivotal role in Korean fisheries development, and analyzes problems of the Korean TAC system. Finally, this paper gives a perspective on expanding the Korean TAC system toward Output Control Systems (OCSs) such as Individual Quotas (IQs), Individual Vessel Quotas (IVQs), Individual Transferable Traps (ITTs), Community Quotas (CQs), and Individual Transferable Quotas (ITQs).     

Considering communities in fisheries management

Fisheries management in the United States, the European Union, and other parts of the globe, increasingly reflects a burgeoning realization that fisheries management policies affect not only fishermen, but also the broader communities in which fishermen work and reside. Understanding fishing communities, however, is not a straightforward task. Researchers draw upon many methodologies across diverse disciplines in the attempt to better understand the needs of fishing communities and the ways in which fisheries management programs affect these communities. This special issue draws together international research on fishing communities, highlighting the diverse relationships between people, places and their fish and fisheries. Rather than attempting to consolidate these complex, multifarious relationships into simple metrics, the papers presented in this issue illuminate community needs and wants from a variety of frameworks highlighting the importance of meaningfully understanding local contexts. These papers represent novel frameworks and case studies, adding depth of scholarly knowledge to a relatively understudied segment of fisheries management. Specifically, the goal of this issue is to advance the inclusion of community considerations in fisheries management processes. While approaching the topic of fishing communities from diverse perspectives, the papers in this special issue work together to provide a broad view of the concerns and conflicts existent in these communities. They highlight the need for management endeavors to be flexible, broad, and inclusive, providing potential tools and frameworks to aid in management projects.     

Integrated coastal fisheries management

There are two principal threats to sustainable coastal fisheries. The concern which has been evident in most parts of the world for many years is the existence of open access to fisheries which has led to over-capitalization, over-fishing of the resource and, often, conflict. Increasingly in recent years, however, a second threat has become apparent. This is the loss of fish habitat and deterioration of water quality brought about by environmental changes generated in other sectors. Integrated coastal fisheries management addresses these issues through a strategy in which the removal of open access plays the key role, supported by elements such as creation of awareness, local participation in management, training and research, and improved sectoral coordination and planning. It is noted that, very often, the amelioration of the second of the two principal threats may be dependent on the fishery sector resolving the first.     

Systems engineering principles in fisheries management

Fisheries management receives valuable, but often fragmented information from academic disciplines such as biology, economics, and social sciences. A multi-disciplinary perspective seems to be necessary if the fisheries are to become sustainable. Globally, overcapacity is considered as the most serious threat to sustainable fisheries, which indicates the need for a stronger integration of technological aspects into fisheries management. This paper discusses application of systems engineering principles and integration of technology into fisheries management. The systems engineering process facilitates implementation of multi-disciplinary information from researchers to fisheries managers in the decision-making towards sustainable fisheries, but may also be used to overcome multi-disciplinary obstacles among scientists. The article concludes that use of systems engineering principles may become a valuable contribution to fisheries management because of increased transparency and reduced risk associated with the decision-making process.     

A natural experiment in fisheries management

The Atlantic sea scallop fishery in the USA and the offshore scallop fishery in the Canadian Maritimes offer a naturally occurring experiment in fisheries management. Canada has adopted a transferable output quota system and the USA has used a mix of size, effort and area controls. This paper compares the consequences over 15 years for the resource, the fishery, and the management regime.     

Sociocultural institutions in Norwegian fisheries management

Many policymakers attribute the success of fisheries management regimes to the design and implementation of particular regulatory tools. While sound design and effective implementation are crucial elements of any successful regulatory action, fisheries policymakers and regulators should also account for the heterogeneous sociocultural institutions of partner communities. The success of fisheries policies relies on compliance and, ideally, cooperation (accepting policies, i.e. not protesting or otherwise strongly agitating against the system) from fisheries stakeholders. Even a policy that is sound in design and flawless in execution is at risk of failure if target stakeholders obstruct or otherwise undermine the system. This paper investigates how institutions, at various levels of scale and formality, play a role in determining the degree of compliance and/or cooperation that a fisheries management regime enjoys. In particular, it will examine the issue of Individual Vessel Quotas (IVQs) in Norway, and the response of fishing communities to the trade liberalization of IVQs.     

The precautionary principle in fisheries management

The precautionary principle has become a reference rule for public actions and policies. Two conceptions coexist under this principle. The first one, based on the strengthening of the concept of environmental protection, aims to promote a prevention proportional to the potential risks. The second one looks for the eradication of risks and it may even require the “proof demand” of innocuousness. The application of the precautionary principle in the fishing sector became established as a reaction in view of the state of resources and the lack of efficacy to guarantee the sustainability of the exploitations. This document tries to stress the application of the precautionary principle in the framework of fisheries. First, it examines the concept of precaution, then it evaluates the concepts applied in the community policy, and thirdly, it concludes by pointing out the problems derived from its implementation.

TAC management in North Sea flatfish fisheries

The Common Fisheries Policy of the European Union adopted in 1983 is primarily focused on a science-based TAC management system with fixed national quota shares. The quality of the assessments of plaice and sole, the consistency of the scientific advice, the congruency of the management decisions, and the enforcement of the regulations are reviewed over a 15-year period. The conclusion is that there have been problems at each level, with the ultimate effect that the policy has not been able to restrict fishing mortality and that the level of overexploitation has only increased. It is argued that the present TAC system has created more problems than it has resolved. Attention is drawn to the autonomic economic developments within the fishery and to the potential for managing the fishery more effectively from the cost side rather than the profit side.     

Law and fisheries reform: Legislative and policy developments in South African fisheries over the decade 1994–2004

Following the enactment of the Constitution in 1996, the South African government undertook a process of legal reform in the fishing sector. This led to the publication of a new fisheries policy endorsing equity and sustainability, as reflected in the Marine Living Resources Act. This paper examines efforts to implement the policy, particularly the objective of “transformation”, against the background of law reform in fisheries over the last decade. The discussion is located within the context of related domestic legal developments and current trends in international fisheries law. Methods for enhancing effective implementation of the new fisheries policy are highlighted.     

Recent developments in offshore rig/ platform evacuation

During severe storms, evacuation systems for offshore rigs and platforms currently in use have proven themselves to be inadequate. Typically, during deployment of a lifeboat, it is often damaged to the point of not being seaworthy before it reaches the ocean surface. This is especially the case for cable-launched boats where a pendulum-like motion of the craft on its cables is often set up. It is less of a problem for free-fall lifeboats. Even when a craft reaches the ocean surface intact, high winds and waves can drive it back against the rig/platform structure. This paper describes the state-of-the-art of evacuation. It focuses on two new systems being developed by the authors in Newfoundland, Canada.     

A cautious fisheries management policy in South Africa: the fisheries for rock lobster

In South Africa, political emancipation has resulted in a new fisheries policy which is embodied in the Marine Living Resources Act of 1998. The pillars of the new policy are sustainability, equity and stability within the industry. We look particularly at a suite of mainly accessible species, the rock lobsters (truly spiny lobsters), at their management, at control measures, at realities of resource status and harvesting, at naturally occurring ecosystem stimuli, and investigate whether the policy can achieve what it aims to do, to provide more for more South Africans at levels at least equal to what they do today. Put simply, are the political aims and the sustainability aims of the new policy mutually achievable?     

Contemporary management issues confronting fisheries science

Stock collapses have occurred worldwide. The most frequently cited cause is over-fishing, suggesting that fisheries management has been ineffective in controlling exploitation rates. The progression of a fishery from an over-exploited to a collapsed state involves impairment of the reproductive capacity of the target species, i.e. recruitment over-fishing. In many cases, this occurs by reduction of the spawning stock biomass (SSB) through the systematic elimination of spawning components within a stock complex. While operational definitions of minimum levels of SSB have been developed, they have seldom been applied and never adopted in a Canadian groundfish management context. The answer to the question of how much is enough to perpetuate a stock under exploitation has been illusive. Serebryakov [J. Cons. Int. Explor. Mer, 47 (1990) 267] has advocated definition of critical levels of SSB based on survival rates (R/SSB). We review his method and discuss the utility of the approach. An alternative approach to the problem of estimating minimum SSB is through a fundamental revision of the traditional stock and recruitment relationship. Explicit theoretical SSB thresholds below which reproduction/recruitment is severely impaired based upon density-dependent mating success (or Allee effects) is considered a superior approach to the question of how much is enough because of its ecological grounding. However, the successful application of this approach will require re-definition of the space/time scales of the management unit. Finally, support is growing for the establishment of closed areas or “no-take zones” as an alternative approach to managing the problems of fishing a stock complex by enabling sub-populations to escape fishing. While the expected benefits of areas protected from fishing are numerous, clear demonstrations of benefits of such areas in marine temperate ecosystems are lacking. In fact, unintended negative consequences may result from such actions.     

Nuts and bolts in fisheries management—a technological approach to sustainable fisheries?

According to the Food and Agriculture Organization of the United Nations, overcapacity in the fishing fleet poses a fundamental challenge in fisheries. Overcapacity leads to an increased pressure on fish stocks and a decrease in economic profit. The fishing fleet is marginalised economically, and overcapacity creates allocation conflicts between different gear and vessel groups. In addition, the expenses to control and management increase. Although Norwegian authorities have introduced several restrictions, for example total allowable catch, licenses, vessel quotas, and other regulatory measures, this article shows that the problems connected to overcapacity persist. Analyses of the technical capacity development show that there is an overall capacity expansion although the number of vessels is reduced. This development is an indicator of the dynamics of technological development over time, and the article discusses whether the concept of technology is sufficiently integrated into fisheries management. The important question now is whether analyses of the technical capacity development can serve as a positive supplement to the traditional fisheries management, which largely is based on input from the scientific disciplines biology and economics.     

On the role of visualisation in fisheries management

Environmental change has focused the attention of scientists, policy makers and the wider public on the uncertainty inherent in interactions between people and the environment. Governance in fisheries is required to involve stakeholder participation and to be more inclusive in its remit, which is no longer limited to ensuring a maximum sustainable yield from a single stock but considers species and habitat interactions, as well as social and economic issues. The increase in scope, complexity and awareness of uncertainty in fisheries management has brought methodological and institutional changes throughout the world. Progress towards comprehensive, explicit and participatory risk management in fisheries depends on effective communication. Graphic design and data visualisation have been underused in fisheries for communicating science to a wider range of stakeholders. In this paper, some of the general aspects of designing visualisations of modelling results are discussed and illustrated with examples from the EU funded MYFISH project. These infographics were tested in stakeholder workshops, and improved through feedback from that process. It is desirable to convey not just modelling results but a sense of how reliable various models are. A survey was developed to judge reliability of different components of fisheries modelling: the quality of data, the quality of knowledge, model validation efforts, and robustness to key uncertainties. The results of these surveys were visualized for ten different models, and presented alongside the main case study.
