Ecosystem Based Fisheries Management

AbstractThe current global crisis in marine capture fisheries contrasts sharply with the recovery of some stocks of marine mammals. Eventually this will have to lead to a re-evaluation of the preferential treatment that marine mammals now often enjoy. The widening support for ecosystem-based fisheries management (EBFM) and the growing insight in the interactions between marine mammals and commercial fisheries are expected to influence this evaluation. This article examines the role of marine mammals in the ecosystem with special emphasis on predation on commercial fisheries. Ample attention is devoted to the definition of EBFM, its legal status and issues of implementation. The 2001 Reykjavik Declaration on Responsible Fisheries in the Marine Ecosystem is used for illustration. One of the conclusions is that sufficient scientific research is required to substantiate positive effects that pre-emptive catches of marine mammals would have for (recovering) commercial fisheries. The regulatory objectives and international legal constraints relevant to marine mammals are moreover addressed to determine if the exploitation of marine mammals could be obligatory or "necessary".

Primary producers are the foundation of marine food webs and require reliable nutrient sources to maintain their important role with ecosystems. While marine mammals and seabirds can play critical roles in marine nutrient cycling, their contributions are often overlooked. Southeast Alaska’s marine environment supports abundant marine mammal and seabird populations in addition to valuable fisheries. Nonetheless, there is still relatively little known about nutrient sources and fluxes in this region which is a critical component of fisheries management. The goal of our study was to advance knowledge of the role of mammals and seabirds in marine nutrient cycling and to understand how changing marine mammal and seabird populations may alter ecosystem dynamics. We utilized qualitative network models (QNMs) to examine how a simulated Southeast Alaska ecosystem would respond to an increase in marine mammals, seabirds, and nutrients. Researchers are increasingly utilizing QNMs as a first step in the development of ecosystem-based fisheries management plans as their adaptable nature is well suited to address rapidly changing climatic conditions. Our results indicate that marine mammals and seabirds make important contributions to marine nutrient concentrations in the region and that these valuable ecosystem services should not be overlooked.

AbstractUnderstanding the trophic niches of marine apex predators is necessary to understand interactions between species and to achieve sustainable, ecosystem-based fisheries management. Here, we review the stable carbon and nitrogen isotope ratios for biting marine mammals inhabiting the Atlantic Ocean to test the hypothesis that the relative position of each species within the isospace is rather invariant and that common and predictable patterns of resource partitioning exists because of constrains imposed by body size and skull morphology. Furthermore, we analyze in detail two species-rich communities to test the hypotheses that marine mammals are gape limited and that trophic position increases with gape size. The isotopic niches of species were highly consistent across regions and the topology of the community within the isospace was well conserved across the Atlantic Ocean. Furthermore, pinnipeds exhibited a much lower diversity of isotopic niches than odontocetes. Results also revealed body size as a poor predictor of the isotopic niche, a modest role of skull morphology in determining it, no evidence of gape limitation and little overlap in the isotopic niche of sympatric species. The overall evidence suggests limited trophic flexibility for most species and low ecological redundancy, which should be considered for ecosystem-based fisheries management.

Ecosystem Based Fisheries Management

We examined a suite of abiotic, biotic, and human metrics for the northeast U.S. continental shelf ecosystem at the aggregate, community, and system level (>30 different metrics) over three decades. Our primary goals were to describe ecosystem status, to improve understanding of the relationships between key ecosystem processes, and to evaluate potential reference points for ecosystem-based fisheries management (EBFM). To this end, empirical indicators of ecosystem status were examined and standard multivariate statistical methods were applied to describe changes in the system. We found that (i) a suite of metrics is required to accurately characterize ecosystem status and, conversely, that focusing on a few metrics may be misleading; (ii) assessment of ecosystem status is feasible for marine ecosystems; (iii) multivariate points of reference can be determined for EBFM; and (iv) the concept of reference directions could provide an ecosystem level analog to single-species reference points.

The Continuum

Abstract Ecosystem management (EM) suffers from linguistic uncertainty surrounding the definition of “EM” and how it can be operationalized. Using fisheries management as an example, we clarify how EM exists in different paradigms along a continuum, starting with a single-species focus and building towards a more systemic and multi-sector perspective. Focusing on the specification of biological and other systemic reference points (SRPs) used in each paradigm and its related regulatory and governance structures, we compare and contrast similarities among these paradigms. We find that although EM is a hierarchical continuum, similar SRPs can be used throughout the continuum, but the scope of these reference points are broader at higher levels of management. This work interprets the current state of the conversation, and may help to clarify the levels of how EM is applied now and how it can be applied in the future, further advancing its implementation.

The article is devoted to the role of executive bodies as subjects of the economic security system of Ukraine. Attention is drawn to the importance of effective administrative activity as one of the basic preconditions for the proper functioning of various branches of the economic sector. It is noted that such activity is of great strategic importance in the issues of ensuring the stability of the national economy and facilitating the necessary development of the latter. An attempt is made to prove that an important role, given their goals, objectives, functions and constitutionally established appointments, is assigned to the executive authorities to facilitate the proper functioning of the national economic system. It has been noted that, among all other bodies of State power, entities have undoubtedly played a significant role in this process and have a special place in the existing State machinery. Attention is drawn to the issues of the concept, as well as to the definition of the structure of the administrative and legal status of the subjects in question. The purpose, tasks and functions of executive bodies as subjects of the system of economic security of Ukraine are defined and characterized. Competence of the said structures in this direction of scientific research is determined, key powers of executive authorities as subjects of the national system of economic security are singled out. It is noted that great importance is given to development of general and coordinated activity of executive authorities, taking into account complexity and multifaceted nature of national economy. It has been noted and an attempt has been made to prove that strengthening external and internal cooperation is a weighty prerequisite for the effective protection of the economic component. It is pointed out that this is especially important in the context of active globalization processes, including those related to the economic sphere. It is noted that such practice also takes place in most EU countries and shows positive statistics from this activity.

The article is devoted to the research of municipal-legal problems of increasing the efficiency of civil society functioning in Ukraine. The emphasis is on the need to improve and strengthen the legal status of local self-government as the fundamental institution of civil society. The contemporary theory of local self-government as an institution of civil society is considered, its role in ensuring the stability of the constitutional system and the development of constitutionalism in Ukraine is determined. The basic theories of self-government are analyzed, the definition of local self-government as one of the main forms of democracy and the constitutional means of limiting state power in the conditions of formation of civil society is proposed. This approach emphasizes the increasing role of the municipal-territorial factor in the life of civil society. It is connected with the creation of capable territorial communities, confirmation of democratic intentions of national states and their special attention to the inhabitants of certain territories.It is concluded that only realization for long time in the minds of residents - members of territorial communities - of stable anti-theatrical institutions, radical changes in the stereotypes of socio-political behavior of the general population, its self-organization and self-discipline, the formation of patriotic sentiments may in the future become the basis for leveling the conflict between state and public interest, the formation of an optimal balance between public and private, and, therefore, a powerful tool for improving efficiency the organization and functioning of civil society.

Abstract Shelton, P. A. 2007. The weakening role of science in the management of groundfish off the east coast of Canada. – ICES Journal of Marine Science, 64: 723–729. The link between science and decision-making for groundfish fisheries off Canada's east coast has weakened during the past two decades. The demand for a large degree of flexibility in the decision-making process by both the Department of Fisheries and Oceans and the Northwest Atlantic Fisheries Organization, as well as the perceived low credibility of scientific knowledge, has resulted in an underutilization of science capacity to provide risk-based assessments and to evaluate management strategies for robustness to uncertainty and compliance with the precautionary approach. The transition from science-based to ad hoc fisheries management is described, and the potential impact of two new approaches, ecosystem-based fisheries management and shared stewardship, is considered.

Abstract Maximum sustainable yield, popularly known by its acronym msy, is perhaps the most disputed concept in the realm of international fisheries law. The first part of this article briefly describes the genesis, development and subsequent adoption of the msy concept in international, regional and national fisheries management instruments. The second part documents the criticisms that the msy concept has generated to date and seeks to find out the legal status of the msy concept in international fisheries law. The third part of this article critically examines the adoption of the msy concept in the legal and policy regime for marine fisheries in Bangladesh. The article argues that more rigorous provisions for conservation of marine ecosystem should be incorporated in fisheries management policies of Bangladesh instead of solely relying on the msy concept as an objective of fisheries management.

Abstract In my article, I discuss the role of informed consent in the context of biobanking. I argue that the basic issue in understanding the role of the consent is one of identifying the interests at stake and determining which of these interests we intend to promote. The definition of the informational content represents only a consequential step. For this purpose, I analyse the legal status of human biological materials from three different perspectives: “material”, “informational” and “relational”. Informed consent produces different effects on each of these perspectives. From the material perspective, consent can influence the allocation of property rights over human tissue; from the informational point of view, consent is the legal instrument that permits control over personal data; while from the “relational” perspective, it is possible through consent to ensure that the person’s personal beliefs are respected. The crucial point is that the legal effects that informed consent has on the three perspectives overlap. Therefore, in order to understand the role of informed consent holistically, in this article I analyse how these perspectives relate to each other. This analysis shows that the relationship between the perspectives can vary depending on the interests that we intend to promote. If we intend to promote the freedom of research, then the material dimension can prevail, whilst if we focus our attention on the interests of individuals then the informational and the relational dimensions will prevail. The challenge is to find a good balance between these two extremes.
