ACAP to hold a workshop in Brazil on Sunday to consider its tuna RFMO strategy

The Albatross and Petrel Agreement will kick off its 2019 round of meetings in Florianópolis, Brazil next week with a one-day strategy workshop on Sunday 5 May to discuss and develop ways for ACAP to engage with tuna Regional Fisheries Management Organisations (tRFMOs).  ACAP has signed Memoranda of Understanding (MoUs) with the five existing tRFMOs and attends and contributes to their meetings every year, as regularly reported in ACAP Latest News.

The objectives and rationale for the workshop as set out in the preparatory document follow:

Workshop objective:  Identify the most effective and efficient ways to engage with tuna Regional Fisheries Management Organisations (RFMOs) to deliver on ACAP conservation objectives (2019-2022).

Workshop rationale: ACAP and ACAP Parties, along with other stakeholders such as BirdLife International and Humane Society International, have been active in engaging with tuna RFMOs (and other RFMOs) for circa fifteen years, in order to reduce bycatch of ACAP species.

In the early period (2005-2012), engagement focused on promoting adoption by tuna RFMOs of seabird conservation and management measures plus subsequent refinement (13 seabird CMM iterations adopted during this period).  2012 was the milestone when all five tuna commissions had adopted measures to require their pelagic longline vessels to use some combination of bycatch mitigation measures in (most) areas overlapping with albatross distribution.

In 2012-2018, ACAP and other stakeholders broadened engagement with tuna RFMOs to seek improvement in bycatch data collection and reporting requirements and to promote plans to review the impact of the seabird CMMs, as well as working to support pelagic longline fleets to implement the seabird CMMs.  There were also further refinements to seabird CMMs, with four seabird CMMs adopted in this period, three of which were in WCPFC [Western and Central Pacific Fisheries Commission].

However, data presented to tuna RFMOs indicate that bycatch rates of ACAP species remain high, while tuna RFMOs have identified that bycatch data collection and reporting remains inadequate for monitoring bycatch levels.  In February 2019, a global seabird bycatch estimation workshop was conducted as part of the Common Oceans ABNJ Tuna Project, generating an estimate of current seabird bycatch levels in the global pelagic longline fleets in the Southern Hemisphere.  In light of this, 2019 is an important moment to assess how best to engage and support global pelagic longline fleets in order to reduce bycatch of ACAP species.

The core elements that the workshop will cover are:

(i) Share views on strengths and weaknesses of using tuna RFMOs as a means to enhance bycatch reduction of ACAP species,

(ii) Based on (i), identify the aspects of seabird bycatch mitigation that are best addressed via tuna RFMO structures versus via engagement at country or fleet level.

(iii) For those aspects identified in (ii), identify the most effective approaches to successful engagement with tuna RFMOs, including what types of meetings to engage with, what inputs will be most effective, who may be best placed to undertake which role,

(iv) Prioritise which tuna RFMOs to engage with, and

(v) Provide feedback on the draft ACAP RFMO Strategy (SBWG9 Doc 07), to be presented at the SBWG9 meeting.”

The results of the workshop will be communicated to the Ninth Meeting of ACAP’s Seabird Bycatch Working Group (SBWG9) which will commence its three-day meeting the next day.

Job Vacancy: Executive Secretary, Southern Indian Ocean Fisheries Agreement

The Southern Indian Ocean Fisheries Agreement (SIOFA) was signed in Rome, Italy in July 2006 and entered into force in June 2012.  The objectives of SIOFA are to ensure the long-term conservation and sustainable use of the non-tuna fishery resources in the SIOFA Area through cooperation among the Contracting Parties, and to promote the sustainable development of fisheries in the Area.  To date, SIOFA has nine Contracting Parties, Australia, the Cook Islands, the European Union, France on behalf of its Indian Ocean Territories, Japan, the Republic of Korea, Mauritius, Seychelles and Thailand, and one cooperating non-Contracting Party, Comoros.  Kenya, Madagascar, Mozambique and New Zealand are also signatories to this Agreement but have not ratified it.

SIOFA is now advertising for a new Executive Secretary, whose role will be to ensure the efficient and effective operation of the SIOFA Secretariat based in Saint-Denis de La Réunion, La Reunion, France.  The deadline for applications is 1 June 2019.  Interviews will take place in the first week of July at the Sixth Meeting of the Parties in Mauritius.  For more details see the Vacancy Notice.

Area of High Seas covered by the Southern Indian Ocean Fisheries Agreement

ACAP signed a Memorandum of Understanding (MoU) with SIOFA in November last year.  The MoU with SIOFA has as its objective the facilitation of efforts to minimise the incidental by-catch of albatrosses and petrels listed in Annex 1 of ACAP that occur within the Area to which SIOFA applies (click here).

Conserving the Flesh-footed Shearwater in New Zealand: halting the “cultural harvest” proposed

Kelly Hare (School of Graduate Research, The University of Waikato, Hamilton, New Zealand) and colleagues have published open access in the Journal of the Royal Society of New Zealand on seven New Zealand plant and animal species with decreasing populations that are deemed “intractable”  to conservation, including the Flesh-footed Shearwater Ardenna carenepeis (globally Near Threatened but nationally Vulnerable).

Conservation actions proposed for the shearwater are land-based predator control, “expanding global co-operation on fisheries bycatch mitigation and halting the “cultural harvest”.

The papers abstract follows:

“Global biodiversity loss is accelerating at an alarming rate. While considerable effort and resources have gone into conservation management for many threatened species in New Zealand (NZ), some species are still ‘losing the battle’ despite much effort, and others have been ignored altogether. Here, we present seven case studies to illustrate the breadth of complex, often ambiguous, threats faced by taxa in NZ. These threats originate from the effects of agriculture and harvesting, irreversible habitat modification and loss, impediments to connectivity, disruption of parasite–host relationships, introduced species and susceptibility to disease, and are further exacerbated by complexities of political and legal inertia, low prioritisation and limited conservation funding. We outline the conservation challenges and identify advances needed to meet NZ's long-term conservation goals. The next 30 years of conservation require new tools in order to protect especially those ‘intractable’ species that have thus far defied efforts to ensure their survival.”

Whose bones are those? Separating Black-browed and Atlantic Yellow-nosed Albatross skeletons

Alice Pereira (Programa de Pós-Graduação em Biologia Animal, Instituto de Biociências, Universidade Federal do Rio Grande do Sul, Porto Alegre, Brazil) and colleagues have published open access in the journal Marine Ornithology on distinguishing skeletal specimens of Black-browed Albatrosses Thalassarche melanophris from those of Atlantic Yellow-nosed Albatrosses T. chlororhynchos.

The paper’s abstract follows:

“Identifying albatross species in the wild involves recognizing plumage pattern and bill coloration. However, skeletal specimens in museums or deteriorated beached carcasses may lack the external characters needed for identification. Although it is possible to distinguish Black-browed Albatross Thalassarche melanophris from Atlantic Yellow-nosed Albatross T. chlororhynchos based on skull morphology, the specimen remains unidentified if the skull is not available. We measured 96 specimens of Black-browed and 55 Atlantic Yellow-nosed albatross, performing 64 measurements for the entire skeleton. Fifty-nine measurements were based on the literature and five new measurements were established specifically for this work. To search for morphometric differences, we first carried out t-tests and principal component analysis (PCA). Then, we performed discriminant function analysis on PCA results and on six selected postcranial measurements to generate a discriminant function. Sixty-one means (93.85 %) of Black-browed Albatross measurements were significantly larger than those of Atlantic Yellow-nosed Albatross. The discriminant function containing the six selected postcranial measurements correctly identified 97.35 % of the specimens through reclassification. This is the first work on osteological morphometric analysis of the entire skeleton for Black-browed and Atlantic Yellow-nosed albatross that is based on a large sample of specimens.”

Individual Grey Petrels exhibit consistent foraging behaviour across years when not breeding

Karine Delord (Centre d'Études Biologiques de Chizé, Villiers-en-Bois, France) and colleagues have published open access in the journal Marine Ornithology on aspects of foraging behaviour of the globally Near Threatened Grey Petrel Procellaria cinerea.

The paper’s abstract follows:

“There is growing interest in the consistency of individual differences in animal behavior as it relates to life history traits and fitness. Despite the relatively large number of studies investigating repeatable behaviors, studies have only recently investigated repeatability in foraging or migratory behaviors, and this has seldom been explored between years. We examined the individual consistency in foraging behavior of the Grey Petrel Procellaria cinerea, a pelagic long-distance migrant. We analyzed how foraging, activity, and migratory patterns were repeatable across different seasons. We used tracking data to monitor the migratory movements and behavior of individuals during the non-breeding period over five years. Despite the small sample size, we found that there was a relatively high individual consistency in wintering strategies across years, with birds displaying high fidelity to their non-breeding destinations during consecutive years. Activity parameters, date of departure of inward migration, duration of migration, and duration spent in non-breeding areas were repeatable as well. The duration of the non-breeding period was the most repeatable, reflecting consistent departure times and, to a lesser extent, consistent arrival times. A high overall repeatability was seen in the timing of the return migration. With respect to sex, males tended to be more consistent in their migration strategy (i.e., timing of migration, time spent in non-breeding areas) than females. Although conditions during the Holocene have generally been stable in the Southern Ocean, species lacking variability in migratory traits are probably at a considerable disadvantage in terms of their capacity to respond to the rapid environment changes currently underway.
