A new field guide should help crew of tuna vessels and observers to correctly identify 44 kinds of sharks and rays that are accidentally caught during tuna fishing in the Western and Central Pacific Ocean (WCPO).
The guide, Shark and ray identification manual, has just been published by the Pacific Community (SPC), and can be downloaded from SPC’s website.
It covers the subtropical and tropical waters of the WCPO, and informs users about the best methods for handling and releasing sharks and rays, recommended by the Western and Central Pacific Fisheries Commission.

Many shark and ray species in the WCPO (and elsewhere in the world) are in danger of dying out, and accidental catch during fishing is a major cause of deaths in some species. If these species are to be saved, scientists and fisheries managers need accurate figures on how many are being caught. And that means being able to identify them reliably.
SPC says that, as well as helping fishers, it also helps observers, who collect operational data from fishing and report back to fisheries managers, who use the information to manage not just tuna fishing but the care of the marine environments that tuna rely on to remain healthy.
To make identification at sea easier, the illustrations show the most important distinguishing features of each species, and its colour when alive.
Identification will also be made easier by the inclusion of the common name for each animal in six languages: Cantonese, English, French, Japanese, Korean, Mandarin, and Spanish.
The manual is written by Timothy Park, Lindsay Marshall, Aymeric Desurmont, Boris Colas and Neville Smith, and illustrated by shark and ray illustrator Dr Lindsay Gutteridge, who is also a scientist.
The new manual refines an older guide that defines 30 species of sharks and rays.

Tuna fishers will have to do everything they can to save rays, including the magnificent manta ray, that are unintentionally caught during fishing operations.
Several species of mobulid rays, which include the mantas, are perilously close to extinction. One of the reasons for this is the numbers that die when they become part of the tuna catch.
The Western and Central Pacific Fisheries Commission (WCPFC) hopes to reverse the trend to extinction. At its 16th annual meeting, delegates agreed on tougher rules aimed at helping rays survive industrial fishing operations. (Wildlife caught accidentally during fishing is known collectively as bycatch.)

FFA summarises WCPFC16 outcomes for Pacific priorities
When Ms Jung-re Riley Kim, the Chair of the Western Central Pacific Fisheries Commission (WCPFC), officially closed its 16th annual meeting on Wednesday, Pacific officials finally relaxed and allowed themselves muted celebrations for a job well done.
Praise for major decisions made by WCPFC16
The Chair of the Pacific’s Forum Fisheries Committee, Mr Eugene Pangelinan, told regional journalists at the final media conference, “This is a very successful WCPFC16, and wonderful hosting by the people and government of Papua New Guinea and the National Fisheries Agency.”
“There’s been some very good outcomes, and the first one is the adoption of the climate-change resolution. From the FFA members’ perspective, that is one of the key priorities we wanted to get out of this meeting, given that one of the things our ministers tasked us to advocate for at the WCPFC was to address climate-change issues in relation to fisheries.”
He said another great outcome was the continuation of the Compliance Monitoring Scheme (CMS) for the next two years.
“The compliance scheme ensures members are held accountable to their obligations and goes a long way to ensuring sustainable fisheries management for the region,” Mr Pangelinan said.
Mr Bubba Cook of the World Wildlife Fund paid tribute to Pacific leadership at the meeting.
He said that the climate resolution “demonstrates that in two consecutive years we have seen a measure that’s been passed – crew welfare in 2018 and now climate change – that is reflective of the leadership in the Pacific island members. The [show a] willingness to take on the tough and challenging issues and provide solutions to those issues, so we are very encouraged by that motivation.”
The Director-General for FFA, Dr Manu Tupou-Roosen, added and re-emphasised the importance of the climate decision. She pointed out its valuable role as a “starting point to increase the focus of the Commission in this critical space so we look forward to that active work in this area with all Commission members”.
She acknowledged the work by Pacific countries as well as other Commission members, “underlining that no one achieves anything alone. Our members have worked really hard including with all Commission members to get to the point we’re at tonight.”
Dr Tupou-Roosen also highlighted positive outcomes for other species that get caught up indirectly as fishers chase the tuna harvest.
“There have been some key outcomes to come out of this Commission related to non-target species. The mobulid rays conservation management measure (CMM) is a win for this Commission; also the adoption of a comprehensive sharks CMM that has taken two years to have adopted.”
Finally able to relax after the intense days of the WCPFC16 meeting: from L–R, Mr Bubba Cook (WWF), Mr Glen Holmes (Pew), Mr Eugene Pangelinan (FFC), Dr Manu Tupou-Roosen (FFA), Mr Noan Pakop (NFA), and Mr Ludwig Kumoru (PNAO)
But some FFA priorities did not progress as well as hoped
But there were also a number of priority issues that did not progress as well as they should.
Mr Pangelinan said, “We were not able to agree on how we are going to proceed with the discussions in terms of the high-seas allocations. That’s something that has been somewhat watered down and now we are going to tackle it at the next WCPFC meeting.”
Mr Glen Holmes, international fisheries officer with Pew Charitable Trusts, praised the success of the rays CMM, but said that work on harvest strategies didn’t go far enough.
“We are very happy with the adoption of the mantas CMM. We think that was a big win for the Commission,” he said.
“But I think there was a very big missed opportunity for the Commission to establish a dedicated meeting for scientists and managers to meet to discuss the issues around harvest-management strategies to further progress that part of the Commission that will lead to a more sustainable management of the stocks into the future.”
Mr Bubba Cook expanded on perceived missed opportunities.
“We think there was some significant progress around a number of issues at the meeting, specifically around harvest-strategy development, but we also remain concerned that some of the measures were not quite as robust as they could have been, particularly for the sharks CMM.
“We have one of the most endangered stock of sharks here in the Pacific with the oceanic whitetip and there were a couple of provisions that would have gone a long way to help with sharks and ensure the long-term sustainability of those stocks. But at the same time there was a great amount of effort that went into the CMM for sharks and it reflects a lot of willingness to compromise around the table, and I certainly would like to acknowledge that as well.
“The manta and mobulid [rays] CMM was also a big step and we are certainly happy to see that move forward.”
Although there was no movement in the skipjack target reference point (TRP) negotiations that are important to members to the Parties to the Nauru Agreement (PNA), there was no harm done, according to Chief Executive Officer for the PNA Office, Mr Ludwig Kumoru.
“Overall, we are happy with the outcome of this Commission meeting,” Mr Kumoru said.
“Our major objective was on the TRP. It may be seen as a push back, but for PNA it is still acceptable, we still have time to work on it. I think if we rushed it and got to a decision where we wouldn’t be comfortable then we would be in a very difficult position. So, we are comfortable with the outcome. The stock is not in the red; it is in the green we can still buy some time and look at ways to address it.”

Looking to the future
In summing up, Mr Pangelinan said, “The Commission has done very well in discussions about future tools that the Commission wants to use to improve monitoring. And two of those are electronic reporting and electronic monitoring. From the FFA perspective, these are important tools that will help fill the gaps in the data from fishing on the high seas in particular and the longline operations.
“So that is something that we also want to highlight: that adopting/agreeing to the objectives here, was a big step to progress the work of the Commission.”
FFA summary of WCPFC outcomes on Pacific priorities
Climate-change resolution – resolution adopted
WCPFC adopted a resolution on climate change based on the draft that was put forward by FFA members at the start of the meeting. This was a significant milestone for the Commission and a great success for FFA Members. The resolution responds to the call from Pacific Islands Forum leaders for increased attention, including in scientific research, to be placed on the impacts of climate change on the region’s highly migratory tuna stocks.
The non-binding resolution also looks at the links between fishing activity and climate change, and for the Commission to consider options to reduce the environmental impacts related to headquarters operations and meetings.
FFA members’ proposal to reform the WCPFC Compliance Monitoring Scheme was one of the hardest issues discussed at WCPFC16.
Cook Islands led the charge for FFA members and, after extensive negotiations, agreement was reached on the last day to a revised measure which focuses compliance monitoring on the implementation of measures by members rather than delving into the detail of individual cases involving fishing vessels that are the better dealt with through other mechanisms.
This was a significant achievement for FFA members, and should see the WCPFC compliance-monitoring process remain the strongest of all the tuna regional fisheries management organisations (RFMOs). The measure agreed to applies for two years, giving time for additional work to take place on additional elements of the scheme including a refinement of audit points and the development of a risk-based framework.
South Pacific albacore – clear direction for roadmap in 2020
There were two informal meetings, chaired by Fiji, of the small working group to discuss the way forward for South Pacific albacore tuna.
The terms of reference and the work plan for the South Pacific albacore roadmap process were progressed, with a focus on rebuilding stock so that catch rates improve. This will assist in improving the economic viability of the fishery.
The roadmap group will hold two face-to-face meetings in 2020, in the margins of the Scientific Committee meeting in August and the Technical and Compliance Committee meeting in September. This should ensure good progress is made before the Commission considers a revised measure in December 2020.
High-seas limits and allocation – two extra days for WCPFC17
While there was general agreement to the proposal from FFA for the WCPFC to hold a two-day workshop to discuss high-seas limits and a framework for allocating those limits, agreement could not be reached on the terms of reference for a workshop. This highlighted how difficult it is going to be reach agreement on allocation within the Commission, especially since allocation decisions can only be taken by consensus. In the end, WCPFC16 agreed to extend the next annual meeting by two days so that time could be devoted to this issue.
Transhipment – slow progress in the intercessional working group
The Transhipment Intersessional Working Group (IWG), co-chaired by RMI and US, made some good progress, but further work remains to finalise the scope of work for a study to identify weaknesses in the existing measure.
A small number of fishing nations remained concerned about the information that would be made available to conduct the study, and this has unfortunately delayed the process. The IWG will continue its work electronically, with the aim of finalising the scope of work as soon as possible.
Mobulid rays conservation and management measure – new measure adopted
FFA members proposed the draft conservation and management measure (CMM) for mobulid rays (such as manta rays), and this was adopted by the Commission following constructive engagement by Commission members. The measure will come into effect in 2021, to allow Commission members time to promulgate the measure with their fishing industries.
Consolidated sharks CMM
After two years of lengthy negotiations, chaired by Japan, a comprehensive measure on sharks was finally agreed. The new measure rationalises and streamlines reporting that was previously spread across a number of different CMMs. There was also some strengthening of the standards around requirements that fins remain naturally attached to shark carcasses with simplification of alternative measures to ensure that they can be monitored and enforced.
PORT MORESBY – The Western and Central Pacific Fisheries Commission (WCPFC) took a major step in helping to protect “threatened” manta and other mobula rays on the final day of its annual meeting on Wednesday.
It adopted a resolution that requires fishers to immediately release any manta rays caught accidentally as “bycatch”.
An international fisheries officer of Pew Charitable Trusts, Glen Holmes, said the increased protection was one of the positive outcomes of the WCPFC meeting, which was held in Port Moresby.
Mr Holmes said the action is considered a “big win” from the commission meeting.
“WCPFC agreed to increase protections for threatened manta and mobula rays by banning purse-seine and longline vessels from keeping any caught in their nets and hooks. This is a positive step and helps remove the incentive for fishers to capture and keep these imperilled species,” Mr Holmes said.
Pacific Islands Forum Fisheries Agency (FFA) members were the proponents of the proposal for a new measure to prevent targeted fishing and retention of mobulid rays, and to promote their safe release, when they are caught in WCPFC convention area fisheries.
FFA Director-General Dr Manu Tupou-Roosen said that the protection of rays is one of the “excellent” outcomes of the WCPFC meeting.
To many island nations such as Palau and FSM, manta-ray watching is a big tourism draw. There is also global plea to protect rays, which not only get tangled in nets and fishing lines but are also targeted for their meat and gill plates.
Under the measure, purse seiners are required to release rays while they are still swimming freely, with rays that are too large to be lifted safely by hand to be brailed out of the net and released using a purpose-built large-mesh cargo net, or canvas sling or similar device.
Purse seiners and longliners are also banned from dragging, carrying, lifting or pulling a ray by its “cephalic lobes” or tail or by inserting hooks or hands.
Bubba Cook, the head of WWF’s delegation to the WCPFC16, said WWF was happy to see that the manta rays measure move forward.
