MeetingMeeting documentCorrelations between environmental factors and CPUEs of blue marlin (Makaira mazara) and striped marlin (Kajikia audax) caught by Taiwanese longline fishery in the Indian Ocean 2013
Also available in:
No results found.This study investigated the correlations between environmental factors (Indian Oscillation Index, Dipole Mode Index, Southern Oscillation Index, sheer currents, amplitude of the shear current, thermocline depth, and temperature at depth of 15/55m and temperature gradient at depth of 15/55m) and nomil CPUEs of blue marlin and striped marlin caught by Taiwanese longline fishery in the Indian Ocean. The results clearly showed that there are significant cycle-patterns between CPUEs and most environm ental factors. In addition, this study also suggested the environmental factors with the time-lags for CPUE standardization alyses of blue and striped marlins in the Indian Ocean. -
MeetingMeeting documentCPUE standardization of striped marlin (Kajikia audax) caught by Taiwanese longline fishery in the Indian Ocean for 1995 to 2011 2013
Also available in:
No results found.This study provided a CPUE standardization of striped marlin (Kajikia audax) caught by the Taiwanese longline fishery in the Indian Ocean for time periods of 1980-2011 and 1995-2011. The delta-lognormal GLM model is adopted to perform the CPUE standardization alysis since blue marlin is caught by Taiwanese longline fleet as bycatch species and large amount of zero catches are recorded in the operatiol data sets. The results indicate that the influence of incorporating environmental effects on CP UE standardization is not significant for striped marlin in the Indian Ocean. The CPUEs in Area MONS and Coastal area revealed similar trends and they substantially decreased since 1980 although the CPUE obviously fluctuated in early years. The CPUE in Area ISSG fluctuated before 1990, substantially increased between 1990 and 1995, and sharply decreased thereafter. In recent years, CPUEs obviously increased for all three areas. The area-aggregated CPUE obviously fluctuated before 1995 and it rev ealed obvious and continuous decline trend thereafter, while it slightly increased in recent two years.

Book (series)GuidelineDéveloppement de l’aquaculture. 4. Une approche écosystémique de l’aquaculture. 2011Les dimensions sociales et biophysiques des écosystèmes sont inextricablement liées de telle manière qu’un changement dans une seule dimension est très susceptible de générer un changement dans une autre. Bien que le changement est une conséquence naturelle des interactions complexes, il doit être surveillé et même géré si le taux et la direction du changement risquent de compromettre la résilience du système. “Une approche écosystémique de l’aquaculture (AEA) est une stratégie pou r l’intégration de l’activité dans l’écosystème élargi de telle sorte qu’elle favorise le développement durable, l’équité et la résilience de l’interconnexion des systèmes socio-écologiques.” Etant une stratégie, l’approche écosystémique de l’aquaculture (AEA) n’est pas ce qu’on a fait, mais plutôt comment on l’a fait. La participation des parties intéressées est à la base de la stratégie. L’AEA exige un cadre politique approprié dans lequel la stratégie se développe en plusieurs é tapes: (i) la portée et la définition des limites des écosystèmes et l’identification de la partie intéressée; (ii) l’identification des problèmes principaux; (iii) la hiérarchisation des problèmes; (iv) la définition des objectifs opérationnels; (v) l’élaboration d’un plan de mise en oeuvre; (vi) le processus de mise en oeuvre correspondant qui comprend le renforcement, le suivi et l’évaluation, et (vii) un critique des politiques à long terme. Toutes ces étapes sont informées par les meilleures connaissances disponibles. La mise en oeuvre de l’AEA exigera le renforcement des institutions et des systèmes de gestion associés de sorte qu’une approche intégrée du développement de l’aquaculture peut être mise en oeuvre et compte entièrement des besoins et des impacts d’autres secteurs. La clé sera de développer des institutions capables d’intégration, notamment en fonction des objectifs et des normes convenus. L’adoption généralisée d’une AEA exigera un couplag e plus étroit de la science, la politique et la gestion. Elle exige aussi que les gouvernements incluent l’AEA dans leurs politiques de développement de l’aquaculture, stratégies et plans de développement.

Book (series)Technical reportReport of the Africa Regional Consultative Meeting on Securing sustainable small-scale fisheries: bringing together responsible fisheries and social development, Maputo, Mozambique, 12-14 October 2010. / Rapport de l’atelier consultatif régional africain sur les pêches artisanales pour une pêche artisanale durable: associer la pêche responsable au développement social, Maputo, Mozambique, 12-14 octobre 2010. 2011

No results found.The African workshop was one of three regional consultative workshops carried out as a follow-up to the 2009 inception workshop of the FAO Extra-Budgetary Programme on Fisheries and Aquaculture for Poverty Alleviation and Food Security. The workshops built on the outcomes of the Global Conference on Small-Scale Fisheries held in Bangkok in October 2008 and referred to the recommendations made by the 26th Session of the FAO Committee on Fisheries (COFI) in March 2009 with regard to the potential development of an international instrument and programme for small-scale fisheries. The purpose of the workshops was to provide guidance on the scope and contents of such an international small-scale fisheries instrument and on the possible priorities and implementation modalities for a global assistance programme. It was organised around plenary presentations on key subjects and working group discussions. The workshop agreed that an international instrument on small-scale fisheries and a rela ted programme would be important tools for securing sustainable small-scale fisheries. It recommended that a small-scale fisheries international instrument and assistance programme should be informed by human rights principles and existing instruments relevant to good governance and sustainable development, comprise the ecosystem approach to fisheries (EAF) as a guiding principle for resource management and development and incorporate Disaster Risk Management (DRM) and Climate Change Adaption (C CA) as an integral part considering that DRM is a continuum process, before, during and after a disaster. The workshop recognised the value and worldwide acceptance of the Code of Conduct for Responsible Fisheries and strongly felt that a small-scale fisheries instrument should be closely aligned to the Code. The instrument should build on what already exists and use a similar language to the Code. In developing the instrument, reference should be made not only to States but also to other sta keholders, recognizing the shared responsibility with regard to resource sustainability and livelihood security. Local, national and regional ownership should be ensured. Implementation aspects should be considered already at the design stage, including the need for technical guidance and supportive mechanisms. Results monitoring should be based on well-defined impact indicators and be an integral part of the implementation modalities. -
Book (series)FlagshipThe State of the World's Land and Water Resources for Food and Agriculture (SOLAW)
Managing systems at risk
2011This edition of The State of the World’s Land and Water Resources for Food and Agriculture presents objective and comprehensive information and analyses on the current state, trends and challenges facing two of the most important agricultural production factors: land and water. Land and water resources are central to agriculture and rural development, and are intrinsically linked to global challenges of food insecurity and poverty, climate change adaptation and mitigation, as well as d egradation and depletion of natural resources that affect the livelihoods of millions of rural people across the world. Current projections indicate that world population will increase from 6.9 billion people today to 9.1 billion in 2050. In addition, economic progress, notably in the emerging countries, translates into increased demand for food and diversified diets. World food demand will surge as a result, and it is projected that food production will increase by 70 percent in t he world and by 100 percent in the developing countries. Yet both land and water resources, the basis of our food production, are finite and already under heavy stress, and future agricultural production will need to be more productive and more sustainable at the same time.
