    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.

    The Ninth Session of the Indian Ocean Tu Commission‘s (IOTC) Working Party on Ecosystems and Bycatch (WPEB) was held in La Reunion, France, from 12 to 16 September 2013. A total of 32 participants (48 in 2012) attended the Session. The meeting was opened by Mr Ludovic Courtois, Secrétaire général du Comité régiol des pêches maritimes et des élevages marins (CRPMEM) de La Réunion, who welcomed participants to La Reunion and formally opened the Ninth Session of the IOTC Working Party on Ecosystems and Bycatch. The Chair, Dr. Charles Anderson also subsequently welcomed participants to La Reunion, including the Invited Expert, Dr. Ronel Nel, from the Nelson Mandela Metropolitan University, Port Elizabeth, South Africa. Employment of a Fisheries Officer NOTING the rapidly increasing scientific workload at the IOTC Secretariat, including a wide range of additiol duties on ecosystems and bycatch assigned to it by the SC and the Commission, and that the new Fishery Officer (Science) supporting the IOTC scientific activities has not been given a mandate by the Commission to work on ecosystems and bycatch matters, the WPEB strongly RECOMMENDED that the Commission approve the hiring of a Fishery Officer (Bycatch) to work on bycatch matters in support of the scientific process. (para.12) Regiol observer scheme The WPEB RECOMMENDED that the Compliance Committee and Commission consider how to address the lack of implementation of regiol observer schemes by CPCs for their fleets and reporti ng to the IOTC Secretariat as per the provision of Resolution 11/04 on a Regiol Observer Scheme, noting the update provided in Appendix VI. (para.35) The WPEB RECOMMENDED that as a priority, the IOTC Secretariat should immediately commence work with CPCs that are yet to develop and implement a Regiol Observer Scheme that would meet the requirements contained in Resolution 11/04, and provide an update at the next session of the WPEB. (para.37) Training for CPCs having gillnet fleets on species id entification, bycatch mitigation and data collection methods and also to identify other potential sources of assistance – Development of plans of action The WPEB RECOMMENDED that the Commission allocate funds in its 2014 and 2015 budgets for the IOTC Secretariat to carry out training for CPCs having gillnet fleets on bycatch mitigation methods, species identification, and data collection methods (budget estimate: Table 4). (para.64) Ecological Risk Assessment: review of current knowledge and pot ential magement implications The WPEB RECOMMENDED that the Commission note the list of the 10 most vulnerable shark species to longline gear (Table 7) and purse seine gear (Table 8) in the Indian Ocean, as determined by a productivity susceptibility alysis, compared to the list of shark species/groups required to be recorded for each gear, contained in Resolution 13/03 on the recording of catch and effort by fishing vessels in the IOTC area of competence. At the next revision to Resolution 13/03 , the Commission may wish to add the missing species/groups of sharks and rays. (para.123) Review of data needs and way forward for the evaluation of shark stocks NOTING that Resolution 10/02 mandatory statistical requirements for IOTC Members and Cooperating Non- Contracting Parties (CPC's), makes provision for data to be reported to the IOTC on ?the most commonly caught shark species and, where possible, to the less common shark species?, without giving any list defining the most common and le ss common species, and recognising the general lack of shark data being recorded and reported to the IOTC Secretariat, the WPEB RECOMMENDED that Resolution 10/02 is revised in order to include the list of most commonly caught elasmobranch species (Table 10) for which nomil catch data shall be reported as part of the statistical requirement for IOTC CPCs. (para.138) Review of Resolution 12/04 on the conservation of marine turtles The WPEB RECOMMENDED that at the next revision of IOTC Resolution 1 2/04 on the conservation of marine turtles, the measure is strengthened to ensure that where possible, CPCs report annually on the total estimated level of incidental catches of marine turtles, by species, as provided at Table 12. (para.168) Resolution 10/02 Mandatory statistical [reporting] requirements for IOTC Members and Cooperating Non- Contracting Parties (CPCs) NOTING that Resolution 10/02 does not make provisions for data to be reported to the IOTC on marine turtles, the WPEB RECOMMENDED that Resolution 10/02 is revised in order to make the reporting requirements coherent with those stated in Resolution 12/04 on the conservation of marine turtles and Resolution 13/03 on On the recording of catch and effort by fishing vessels in the IOTC area of competence. (para.169) Format of future WPEB Sessions The WPEB RECOMMENDED that the SC note the following: (para.253) ? The WPEB DISCUSSED the future format in order to focus the efforts of scientists working on different groups of bycat ch species to address more efficiently, the mandate of the group. ? The WPEB CONSIDERED a range of options which the SC is asked to consider: o Option 1: The current WPEB be split into two; A dedicated Working Party on Sharks (WPS) and a Working Party on Ecosystems and Bycatch (WPEB). o Option 2: Retaining the WPEB in its current form, with alterting focus of sharks in one year, followed by other ecosystem and bycatch issues in the next year. o Option 3: Maintaining the WPEB with clear guideline s to deal with sharks every year, as well as other issues and bycatch groups in alterte years or as required. ? The WPEB AGREED that shark issues were important to address on a yearly basis. Election of a Chairperson and Vice-Chairperson for the next biennium The WPEB RECOMMENDED that the SC note the new Chairperson, Dr. Rui Coelho (EU,Portugal) and Vice- Chairperson, Dr. Evgeny Romanov (La Réunion), of the WPEB for the next biennium. (para.263) Report of the Ninth Session of the Working Party o n Ecosystems and Bycatch The WPEB RECOMMENDED that the Scientific Committee consider the consolidated set of recommendations arising from WPEB09, provided at Appendix XXI, as well as the magement advice provided in the draft resource stock status summary for each of the seven shark species, as well of those for marine turtles and seabirds: (para.265) Sharks o Blue sharks (Prioce glauca) – Appendix X o Oceanic whitetip sharks (Carcharhinus longimanus) – Appendix XI o Scalloped hammerhead sharks ( Sphyr lewini) – Appendix XII o Shortfin mako sharks (Isurus oxyrinchus) – Appendix XIII o Silky sharks (Carcharhinus falciformis) – Appendix XIV o Bigeye thresher sharks (Alopias superciliosus) – Appendix XV o Pelagic thresher sharks (Alopias pelagicus) – Appendix XVI Other species/groups o Marine turtles – Appendix XVII o Seabirds – Appendix XVIII A summary of the stock status for some of the most commonly caught shark species caught in association with IOTC fisheries for tu and tu-like species is provided in Table 1.
