Synopsis (short abstract) The Fifteenth Session of the Indian Ocean Tu Commission‘s (IOTC) Working Party on Tropical Tus (WPTT) was held in San Sebastian, Spain, from 23 to 28 October 2013. The meeting was opened on 23 October 2013 by the Chair, Dr Hilario Murua (EU-Spain), who welcomed participants to San Sebastian, Spain. A total of 46 participants attended the Session (47 in 2012), including one invited expert, Dr. Andrew Cooper, from Simon Fraser University, Cada. The following are a subset of the complete recommenda tions from the WPTT15 to the Scientific Committee, which are provided at Appendix XII. Japan data collection and processing systems The WPTT THANKED Japan for addressing some of the concerns raised by the WPTT in 2012, and RECOMMENDED that Japan and the IOTC Secretariat continue joint work, in cooperation with other countries having longline fisheries, to address other issues identified by the WPTT, as the lack of specimens of small size from the samples and discrepancies in the average weights estimated using the available catch-and-effort and length frequency data. (para. 62) Taiwan,Chi data collection and processing systems NOTING that in recent years fishers from the Taiwan,Chi longline fleet have been collecting both length and weight measurements for the same specimens, the WPTT RECOMMENDED that the measured lengths and lengths derived from weight measurements are compared in order to validate the reliability of this dataset (para. 67) Length Frequency inter-sessiol meeting guide lines NOTING the size data issues (discrepancies in catch, effort and notably size data (low sampling rate, uneven distribution of sampling in regard to the spatial extent of the fishery) in the Japanese and Taiwan,Chi tropical tu data sets) identified by the WPTT in 2012 and 2013 and the Scientific Committee in 2012, the WPTT RECOMMENDED that an inter-sessiol meeting attached to the WPDCS and WPM on data collection and processing systems for size data from the main longline fleets in the Indian Ocean, be carried out in early 2014, under the guidelines contained in Appendix IV. (para. 74) The WPTT NOTED that the data collection and processing systems used for distant-water longline fisheries tend to apply to all oceans AGREEING that it is likely that the issues identified for the Indian Ocean also apply to other areas. In this regard, the WPTT RECOMMENDED that the IOTC Secretariat informs other tu-RFMO Secretariats about the issues identified and facilitates participation of their staf f to the WPDCS, where required. (para. 75) India fisheries NOTING the potential utility of the longline CPUEs derived from the research surveys conducted by the ?Fishery Survey of India?, the WPTT RECOMMENDED that as a high priority, India undertake a standardisation of the CPUE series, with the support of the IOTC Secretariat, and for this to be presented at the next WPTT meeting. (para. 92) Alysis of the Time-Area Closures (including Resolution 12/13) NOTING that the objective of Resolution 12 /13 is to decrease the overall pressure on the main targeted stocks in the Indian Ocean, in particular yellowfin tu and bigeye tu, and also to evaluate the impact of the current time/area closure and any altertive scerios on tropical tu population, the WPTT reiterated its previous RECOMMENDATION that the SC request that the Commission specify the level of reduction or the long term magement objectives to be achieved with the current or altertive time area closures, as these are not contained wit hin Resolution 12/13. (para. 245) Review of the draft, and adoption of the Report of the Fifteenth Session of the WPTT The WPTT RECOMMENDED that the Scientific Committee consider the consolidated set of recommendations arising from WPTT15, provided at Appendix XII, as well as the magement advice provided in the draft resource stock status summary for each of the tropical tu species under the IOTC mandate: (para. 271) o Bigeye tu (Thunnus obesus) – Appendix VII o Skipjack tu (Katsuwonus pelamis) – Appendix VIII o Yellowfin tu (Thunnus albacares) – Appendix IX A summary of the stock status for tropical tu species under the IOTC mandate is provided in Table 1.

    Développement de l’aquaculture. 4. Une approche écosystémique de l’aquaculture. 2011
    Also available in:
    Les 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.

    Forests and forestry in the Greater Mekong Subregion to 2020
    Subregional report of the second Asia-Pacific forestry sector outlook study
    2011
    Also available in:
    No results found.
    In the 12 years since the first Asia-Pacific Forestry Sector Outlook Study was completed in 1998, the region has experienced tremendous changes in nearly every aspect. These changes have been particularly profound in the forestry sector, where society has dramatically increased its demands and expanded its expectation of forests and forestry. This subregional report for the Greater Mekong Subregion (GMS) summarizes the key findings and results collated under the second Asia-Pacific Forestry S ector Outlook Study - a comprehensive effort spanning nearly four years and involving all member countries of the Asia-Pacific Forestry Commission. The current report synthesizes observations and findings from five GMS country reports, numerous thematic reports and a wide ranging review of current and past publications in providing analyses of the status and trends of forests and forestry in the GMS. The publication also analyses key factors driving changes in forestry in the region and sets out four scenarios for 2020: Hard times, Slow and steady, Overburn and Living on the edge. The report also outlines priorities and strategies to move the subregion's forestry sector onto a more sustainable footing and to provide continued benefits to future generations.

    Fisheries management, v. 4: Marine protected areas and fisheries 2011
    Also available in:
    This document on Marine protected areas (MPAs) and fisheries has been developed to provide information and guidance on the use of marine protected areas (MPAs) in the context of fisheries. As MPA implementation moves ahead in the arena of marine biodiversity conservation, many people feel that the fisheries aspects are not fully understood nor always appropriately taken into account, and that guidance specific to this sector is needed. These Guidelines look specifically at fisheries features of MPAs, but also address the interface between fisheries management and biodiversity conservation and provide support for MPAs with multiple objectives. The document highlights the need for increased coordination across sectors and agencies/departments. Integration of diverse interests and viewpoints is required if we are to successfully manage our oceans and their resources for future generations. As with all fisheries management, good governance – including adequate stakeholder participation – i s key to successful and equitable management outcomes.
