Abstract An ecosystem approach to fisheries management (EAFM) is as a new paradigm in fisheries management. In this study, a combination of geographic information systems (GISs) and multi-criteria decision-making method (MCDM) is proposed as a framework supporting an ecosystem approach to European sardine (Sardina pilchardus, Clupeidae) fishery management in Portugal. This case study was chosen due to the recent severe decline shown by the species. To develop an EAFM for the sardine fishery, a set of criteria were defined based on literature review and expert knowledge. To address multiple conflicting objectives, namely conservation and fisheries, five scenarios were considered: (i) baseline; (ii) nurseries protection; (iii) spawning areas protection; (iv) fishery profit driven, and (v) safeguarding dependent fishing communities. Combination of GIS and MCDM methods highlighted important areas to implement spatial conservation measures for sardine. The analyses indicate that some areas are suitable for conservation in several scenarios, such as the area near Aveiro and the area near the Tejo estuary. However, conservation measures implemented in the area near Aveiro would imply higher economic trade-offs when compared with the actions applied in the region near the Tejo estuary. Results also suggested some of the conservation objectives, such as the protection of sardine eggs and juveniles, to not be compatible. The proposed framework is an important tool supporting EAFM by addressing conflicting objectives, trade-offs and identifying areas that could be considered as potential fishery closure sites or subjected to further analyses.

The Government

The sustainability of marine ecosystem has become a major concern the government; however, the implementation of sustainability-based fisheries management has not been fully carried out and well controlled. Therefore, having a concept of ecosystem-based fisheries management (EBFM) is essential in protecting it preserved. The aim of this study was to analyze the implementation of EBFM in Karimunjawa ecosystem, Central Java, Indonesia. The analysis of this study was based on the primary data collected from fishermen and stakeholders using in-depth interviews, and the secondary data gathered from stakeholders of Karimunjawa documentation. Meta-analysis with triangulation was invoked in this study. The result showed that the vulnerability of marine ecosystem, particularly fisheries’ resource in the pilot project is in progress. The conventional approach has not yet succeeded in managing fisheries’ resource in terms of sustainability attributes. Moreover, the EBFM has not yet proven to be a suitable approach for some reasons; although, this concept is very promising in encouraging a new paradigm for sustainable management in Indonesia with a protocol concept. This initial finding needs to be furthered in order to explore other aspects of development.

The Us

Recent global improvements to fisheries sustainability have been made through the adoption of more holistic management frameworks, such as the ecosystem approach to fisheries management (EAFM) and ecosystem-based fisheries management (EBFM), and a concurrent transition from a focus on single species or stocks to multispecies and ecosystems. In the US, federal and regional fisheries management encompass multiple layers of comprehensive, ecosystem focused management strategies for living marine resources within its network of large marine ecosystems (LMEs). Here, we provide an overview for the US portion of the Gulf of Mexico large marine ecosystem (GOM-LME) by examining multiple aspects of its fishery management scheme through the lenses of EAFM, EBFM, and the integrated ecosystem assessment (IEA) framework that has been used worldwide to advise, inform, and operationalize ecosystem management. The US-GOM's fishery management and ecosystem community appears to be keeping pace with other US regional efforts. However, more tools like fishery ecosystem plans (FEPs), which are conducive to the effective integration of ecosystem considerations into fishery management processes, are needed to inform and guide the work of regional managers, decision-makers, and stakeholders. Therefore, we propose a structured planning process aimed at advancing the development and implementation of a GOM-FEP, and describe two case studies of EAFM and EBFM applications, respectively, that can help to navigate through our proposed planning process. This work offers strategic guidance and insights to support efforts of regional fishery managers to translate ecosystem management principles, approaches, and objectives into an "action oriented" FEP in the GOM-LME.

Abstract Laptikhovsky, V. 2011. Migrations and structure of the species range in ridge-scaled rattail Macrourus carinatus (Southwest Atlantic) and their application to fisheries management. – ICES Journal of Marine Science, 68: 309–318. The biology, distribution and abundance of the ridge-scaled rattail (Macrourus carinatus) was studied in four seasonal bottom-trawl surveys in 2006–2009 using biological material collected on board different research and commercial fishing vessels. The species was found to exhibit ontogenetic and seasonal migrations. Upon switching to the demersal lifestyle, juveniles gradually move north with the Falkland Current. Adults return to the spawning areas (50–54°S) and remain there. They move seasonally along the slope from 54°S to 50°S between 500 m and 900 m, with males and females moving separately. The northernmost aggregations (at 50–51°S) occur in autumn, during the major spawning event. In winter, fish migrate south. During spring and summer the entire population gradually shifts north with ongoing minor off-season spawning. Females, which are the larger sex, tend to stay shallower than males. Such a sex-related migratory behaviour should be taken into account when the existence or absence of Heincke's law is considered for a particular species. A complicated migratory pattern should also be accounted for in fishery management.

Environmental Decision

Environmental decision making has to deal with trade-offs between social, political, environmental, and economic impacts, with different stakeholders' views, which rely on expert knowledge and expertise. This chapter describes how such environmental decision processes can be explored, analyzed, documented, and formalized. Decisions in this problem area depend notably on expertise and experience acquired by all involved decision makers. In this chapter, a collaborative approach is developed and applied that integrates the stakeholders as a partner into the modeling process. After the decision process is documented using the card game CUTA4BPM, all information, which leads up to a decision, will be collected, systemized, and grouped using supplementary paper cards. The outcome of this modeling leads to a formalized model of the decision process. On account of this approach, the real decision process is modeled and increases trust in the decisions suggested by a decision support system later on. This collaborative approach is evaluated by a case study in crop planning.

Conflicting Objectives

This research attempted to build a framework for determining optimal routes for hazardous materials transportation. Previous work has suggested the incorporation of many conflicting objectives in the analysis, such as travel cost, population exposure, environmental risk, and security concerns. Multiplying the number of objectives leads to complex shortest path problems that often have several efficient solutions. The present study emphasizes an overview of possible trade-offs among routes without generating all of them. A simple characterization of the efficient routes is used to select the best ones with no need for input from the decision maker. A case study with eight objective functions was performed on a road network in Singapore. A geographical information system was used to quantify road link attributes, which are assumed linear and deterministic for the sake of simplicity. The proposed algorithm derives four significantly different routes, which conform to intuition.

An EAFM from a global perspective is still moving towards on implementation. EAFM is based on conventional fisheries management but broadens the perspective beyond seeing a fishery as simply “fish in the sea, people in boats,” beyond consideration only of commercially important species, and beyond management efforts directed solely at the harvesting process. This research aims to initiate implementing EAFM in Indonesia: case in Tarakan Fisheries, North Kalimantan Province. From the initiate implementation of EAFM, we found that the possibility to improve the performance on arrange fisheries management based on ecosystem approach. EAFM could be used as tools to confirm scientific findings and gathering initial information on fisheries. In the case, fisheries community in Tarakan was put human well-being as important point to determine fisheries management, rather than ecological well-being. To secure the fisheries the possible options would arrange accepted and adaptable policy on controlling fisheries i.e. temporary fishing closure in term of area and season.

The Status

There are a large variety and quite abundant types of small pelagic fish that have high economic value in the Sulawesi Sea. One of which is the blue scad fish or commonly known as malalugis (Decapterus macarellus). This study aims to analyze and determine the status of scad fisheries management and to develop recommendations in the management of scad fisheries in the waters of Sulawesi Sea, North Sulawesi Province. The evaluation of fishery management status is carried out using multi-criteria analysis (MCA) through the development of composite index of each indicator of Ecosystem Approach to Fisheries Management (EAFM). The results showed that, in general, the status of scad fisheries management in North Sulawesi Province, was in ‘good’ category, specifically reviewed from the domain of fish resources fall into the category of “medium”, habitat and ecosystem “good”, fishing techniques “good”, economy “not good”, social “medium” and institutional “good”. Management actions take precedence over domains that have “poor” indicator values. Priority management action is implemented in the economic domain, followed by the domain of fish resources, social, institutional and fishing techniques.Indonesian title: Pengelolaan perikanan ikan layang (Decapterus spp.) di perairan Laut Sulawesi, Provinsi Sulawesi Utara, menggunakan EAFM
