Delineating the stock structure of highly-mobile, wide-ranging fishes subject to exploitation is a challenging task, yet one that is fundamental to optimal fisheries management. A case in point are stocks of skipjack tuna (Katsuwonus pelamis), yellowfin tuna (Thunnus albacares), bigeye tuna (Thunnus obesus) and albacore tuna (Thunnus alalunga) in the Pacific Ocean, which support important commercial, artisanal, subsistence, and recreational fisheries, and contribute roughly 70 % of global commercial tuna catches. Although some spatial and temporal structuring is recognised within these stocks, growing evidence from a range of approaches suggests that the stock structure of each tuna species is more complex than is currently assumed in both stock assessment... |

An evaluation framework developed to help select an appropriate suite of indicators to support an ecosystem approach to fisheries management was tested experimentally by asking independent experts to weight the selection criteria provided and to score indicators against those criteria in several ecological settings. The steps in selecting indicators proved to be prone to subjectivity and value judgement, and differences in scores between experts were the main factor contributing to variability in evaluation results. Having to justify scores in a written document did not improve consistency among the experts. The framework, however, did enhance transparency by explicitly stating each issue to be addressed in the selection process, and by giving experts or... |

Ecosystem-based management (EBM) of the ocean considers all impacts on and uses of marine and coastal systems. In recent years, there has been a heightened interest in EBM tools that allow testing of alternative management options and help identify tradeoffs among human uses. End-to-end ecosystem modeling frameworks that consider a wide range of management options are a means to provide integrated solutions to the complex ocean management problems encountered in EBM. Here, we leverage the global advances in ecosystem modeling to explore common opportunities and challenges for ecosystem-based management, including changes in ocean acidification, spatial management, and fishing pressure across eight Atlantis (atlantis.cmar.csiro.au) end-to-end ecosystem... |

The scope of this study is to investigate the extent to which area-based management may have influenced the fishing efficiency of the Danish and Dutch demersal fleets harvesting cod, plaice and sole in the North Sea. Special consideration is given to the 'plaice box', a restricted area where fishing is prohibited to towed-gear fleets of horsepower exceeding 300 hp. An index of fishing power is calculated as the log-ratio between the catch per unit effort (CPUE) of any vessel and some survey abundance index. Annual trends in fishing are calculated as the year-effect derived from a general linear model (GLM) analysis of the index of fishing power. The fishing efficiency of Danish gill-netters and, to some extent, Danish seiners, has overall increased inside... |

This work is the result of collaboration between the English, French, Channel Isles and Belgian laboratories which are involved in a study of the English Channel. Its subject is the activities of fleets and fleet interactions, and it complements other work on the biogeographical identification of Channel fish and shellfish stocks (published), and on modelling the fleets' interactions as they exploit the resources (in preparation). The concept of a métier is defined as being the use of one fishing gear to catch one or several species targeted during a particular season in a given area. On this basis, 74 métiers were identified during 1989-90. For each métier we give a brief description of the catching gear, the target species and most usual by-catch, the... |

A standard, universally useful classification scheme for deepwater habitats needs to be established so that descriptions of these habitats can be accurately and efficiently applied among scientific disciplines. In recent years many marine benthic habitats in deep water have been described using geophysical and biological data. These descriptions can vary from one investigator to another, which makes it difficult to compare habitats and associated biological assemblages among geographic regions. Using geophysical data collected with a variety of remote sensor systems and in situ biological and geologic observations, we have constructed a classification scheme that can be used in describing marine benthic habitats in deep water. |

This paper describes the fishing activity in Martinique, French West Indies. It draws up the balance sheet of acquirements about marine resources of the island. The difficulties of fisheries management are discussed with reference to biologists and economists works in the last ten years. We also show how management efforts to decrease fishing pressure on reef resources has induced the implantation of a new technology: the Fish Aggregating Deviee. The differing histories of development of FADs in the French West Indies are compared. The positive results from the introduction of the FADs and the estimated risks due to the transferance of fishing pressure on the continental shelf is presented. The use of FADs to enhance the exploitation of marine resources is... |

Many marine fish stocks are overexploited and considerable overcapacity exists in fishing fleets worldwide. One of the reasons for the imbalance between resource availability and fishing capacity is technological development, which continuously increases the efficiency of the vessels—a mechanism referred to as “technological creep.” We review how the introduction of new and more efficient electronic equipment, gear design, engines, deck equipment, and catch-handling procedures influences the capture efficiency (catchability) of commercial fishing vessels. On average, we estimate that catchability increases by 3.2% per year due to technological developments, an increase often ignored in fisheries management. The documentation and quantification of... |

Fisheries co-management has two agendas associated with it that sometimes work together and sometimes contend. The first agenda is to make fisheries management more rational, meaning making it better able to achieve its objectives. The second agenda is to make fisheries management more equitable by giving those people who have the most at stake in management decisions a greater say in those decisions. The knowledge on which co-management is based plays a critical role in both of these agendas. If the knowledge needed for management, for example about the condition of a fish stock, is more realistic and easier to get, this helps management to be more rational. If the knowledge needed for management is contributed to, shared and controlled by more... |

This report discusses the present status of the Cameroon Fisheries regulation with respect to the United Nations Convention on the Law of the Sea (UNCLOS) and other International Conventions notably, the International Plan of Action-Illicit, Undeclared, Unregulated fishing (IPOA-IUU). It presents an overview of the fisheries resources of Cameroon analyzing fish production, management, exploitation, postharvest treatment, fish transport, commercialization and consumption. Major threats to sustainable exploitation and management are also herein discussed. Results reveal that the United Nations Convention on the Law of the Sea (UNCLOS) and other International Conventions do impose significant new commitments to the Cameroon fisheries legislation and that... |

The paper sets out with a brief review of the status of marine fishery resources and the principal fisheries management issues in the Indian Ocean region. It then presents important international instruments for fisheries management and, in general terms, reviews progress in their implementation. The term ‘international’ is defined broadly to also encompass the conventions of regional or sub-regional fisheries management organizations (RFMOs). The paper focuses on fisheries management in the conventional sense of making optimum use of the fishery resources. Instruments addressing the protection of fish habitats from pollution and degradation are also addressed but in less detail. |
