If I had to summarize my previous journeys in Senegal in one word, I would certainly use ‘denial’ for the first trip, ‘hope’ for the second, but many words for my last visit to Dakar last November when Dr. Daniel Pauly and I represented the Sea Around Us Project at the Forum of the Regional Marine and Coastal Conservation Programme for West Africa (Programme Régional de Conservation de la zone côtière et Marine; PRCM). The description of the Forum that can be found on the PRCM website underlines the importance of this event (www.forumprcm.org).

The theme of the Forum was ‘Investing in coastal and marine conservation for the wellbeing of populations’, and as suggested, its goal was to put forward ideas about the use of nature with a view to improve the wellbeing of people relying on it. Many different stakeholders were present (e.g., NGOs, professional fishers, scientists, decision-makers) and were eager to discuss sustainability and conservation.

I was delighted to meet again our collaborators and colleagues from Cape Verde, The Gambia, Guinea, Guinea-Bissau, Liberia, Morocco, Senegal, and Sierra Leone, as well as from the Fishery Committee for the West Central Gulf of Guinea (FCWC) countries, notably Ghana and Côte d’Ivoire. On a lighter note, a young man from Tanzania presented his journey as he biked from Chile to Tanzania, raising awareness about the environment and funds for Tanzanian students along the way. He also reminded me that I am not the only person in this world who needs a visa to go to conferences and talk about issues and potential solutions for a sustainable use of the ocean. After all, if fish needed a visa, the issue of illegal fishing would not be that bad. Illegal fishing was actually one of the topics of the Forum, and our colleague Duncan Copeland talked about how to implement efficient, non-expensive solutions to tackle illegal fishing. While some Mauritanian representatives claimed that illegal fishing was no longer as significant as it was in the past, a representative from Guinea-Bissau stated that the coastal waters of “Bissau looked like Hong Kong at night”, referring to the lights of the industrial fishing boats illegally venturing into artisanal fishing grounds at night. Afterwards, I was not able to make up my mind between ‘content’ — as ‘admitting’ is the first step towards ‘healing’ — or ‘sadness’ — as the issue of illegal fishing is now so important, that being politically correct is no longer an option.

The presence of journalists made for a great opportunity for the Sea Around Us Project to share our knowledge of West African fisheries with the public, and to emphasize the implications of our catch reconstruction work. For example, I had the opportunity to clarify some points such as “women’s catches are not substantial, therefore, it is not an important activity”. Indeed, one can argue that if this activity allows women to be financially independent and provide their households with food, then, it is of paramount importance, regardless of the volume of the catch (especially if vulnerable species are targeted).

At the end of the day, the Forum was a very productive experience for the Sea Around Us Project, as NGOs, research institutes, and regional organizations were eager to use and work with the catch reconstruction results. Indeed, they all agreed that looking at the impact of local small-scale fisheries, filling data gaps, and contributing to capacity building in the region is an important process. For example, we discussed catch reconstructions with representatives from Morocco (who were keen to work with us) and from the FCWC region (with whom we recently signed a Memorandum of Understanding), as well as with traditional community representatives such as the Imraguen, who constantly remind us of the reasons why we are fighting to save our oceans.

After the Forum, Daniel and I had the honour of having an informal lunch with his Excellency the Minister of Fisheries of Senegal, Haïdar El Ali, who informed us of his decision to invite the Sea Shepherd Conservation Society to act in Senegal. It was pleasant to have a conversation with him as he seemed to be a person who is deeply driven by conservation. As we came back from Dakar, we also learned that Senegal had just arrested illegal Russian fishers despite diplomatic pressure from Russia. This action was backed by numbers the Sea Around Us Project estimated with colleagues from USAID and many other Senegalese organizations.

Ensuring better fisheries management in West Africa


This week, the Sea Around Us Project’s Principal Investigator, Daniel Pauly, and one of our PhD students, Dyhia Belhabib, attended the Regional Marine and Coastal Forum held in Dakar, Senegal, where representatives from eight West African countries gathered to discuss the status of fisheries in the region and their future. Their goal was to engage the countries in tackling unreported fishing.

By working with researchers at the Sea Around Us Project to assess their fisheries from 1950 to 2010, these countries have identified the extent of unreported fishing in their waters – which is often as much as double what is officially reported.

“Fishing operations in West Africa have been catching much more than anyone previously realised and reported,” says Dyhia Belhabib. “The research we are conducting in partnership with West African countries gives them the first complete historical picture of their fisheries.”

In response, some countries in the region have started to take steps to address the gaps and improve fisheries management. In Senegal, the government has developed a fisheries commission and signed an agreement to improve the current reporting and management of its fisheries.

“This joint research is shedding new light on the true extent of past fishing in West Africa,” says Daniel Pauly. “Our hope is that these countries will now adopt the results and use them to contribute to better fisheries management in the future.”

EU fishing companies reap profits in developing countries, while taxpayers foot the bill

The European Union (EU) covers 75% of the access fees that allow its vessels to fish in developing countries’ waters while the fishing companies pocket the profits, according to new research from the Sea Around Us Project.

In a study published today in the online journal PLOS ONE, the authors analyzed access agreements that allow EU-based fishing fleets to operate in Africa and the South Pacific. They found that EU governments pay 75% of the annual access fees while the fishing industry pays the remaining 25% — but that represents only about 2% of the revenue it generates from selling the catch.

“The EU’s fishing companies are benefitting from these agreements far more than the developing countries where they go to fish,” says Frédéric Le Manach, a PhD student at with the Sea Around Us Project and the study’s lead author.

ELEFAN in (Daka)R

Participants

During June, Deng Palomares and Daniel Pauly spent a week teaching a newly updated version of the ELEFAN software at the Institute for Fisheries and Aquaculture of the University Cheick Anta Diop of Dakar, Senegal. (Photo: Najih Lazar)

The ELEFAN software and approach for the estimation of von Bertalanffy growth parameters from length-frequency data was developed at the International Center for Living Aquatic Resources Management (ICLARM), in Manila, Philippines, in the early 1980s by Daniel Pauly and two programmers (Noel David and Felimon Gayanilo). It was disseminated in various versions throughout the world, especially in tropical countries, through a series of training courses during the 1980s and 1990s. It also formed the core of a comprehensive software package called FAO-ICLARM Stock Assessment Tools (FiSAT; [1], [2]), still available from the FAO.

Overall, about 5,500 papers based on the ELEFAN approach, as incorporated in FiSAT and its predecessors have been published in the past 30+ years (as identified by Google Scholar records with “ELEFAN” in the title or the body of the text). However, since its release, FiSAT has been updated only once (FiSAT II; [3]), and it has become outdated in content and form. Thus, the offer was accepted to collaborate with USAID’s COMFISH Project in Senegal to produce an updated version of ELEFAN and to test it in a training course in Dakar before releasing it for wider use as open-source software.

The bulk of the R coding was completed by Aaron Greenberg (with Mathieu Colléter also contributing a routine) just in time for a team consisting of Ted Hart (of UBC’s Biodiversity Research Centre), Danielle Knip and Deng Palomares (of the Sea Around Us Project) to create a stand-alone package copied on 25 USB sticks at the end of May.

Daniel Pauly and Deng Palomares then spent a week in an ELEFAN training course, held at the Institute for Fisheries and Aquaculture of the University Cheick Anta Diop of Dakar, teaching the routines behind and the functioning of the ELEFAN package. The group of 25 Senegalese participants consisted of about one-half fisheries scientists and graduate students, and the other half of fisheries inspectors.

While the fisheries inspectors struggled somewhat with the relevance of growth and mortality estimations and clearly preferred Daniel’s lectures on fisheries and climate change issues, the students and scientists benefitted greatly from this training workshop and generated – with Deng’s help – results for sardinella (Sardinella aurita, S. maderensi), white grouper or thiof (Epinephelus aeneus), bonga (Ethmalosa fimbriata) and other species. The results – to our relief – were comparable to those obtained by a group of colleagues (also working for the COMFISH Project) through tedious reading of annual rings on bony structures. Indeed, in the case of octopus (where the cubic root of the weight was used instead of length), results were obtained which could not have been obtained though ageing of bony structures – octopi
have no bones…

Thus, overall, the personnel who had arranged the workshop, notably COMFISH Project Leader Chris Mathews and Najih Lazar, Technical Advisor, both of The University of Rhode Island, were as pleased as we were about both the knowledge that was passed on during the workshop and the performance of the trial version of ELEFAN in R. Obviously, a number of items were noted which require improvement, as well as a swarm of bugs, both of which are due to be fixed in the next two to three months. The high hopes that we have for this new release of ELEFAN in R appear justified.

Daniel used the opportunity of being in Senegal to visit the Département des Pêches Maritimes, where he briefed its Director, Mr. J.-P. Manel, and members of his senior staff on the results of the reconstruction of Senegalese marine catches led by Dyhia Belhabib, with support from the MAVA Foundation and co-authors from the COMFISH project (Ms. Vivianne Koutob), the DPM (Mr. Lamine Mbaye) and WWF-Senegal (Mr. Nassirou Gueye). It was very gratifying that our Senegalese partners acknowledged that they have catch-reporting problems, both with regards to substantial illegal fishing in Senegalese waters and unregulated fishing by Senegalese fishers in the waters of neighbouring countries. This acceptance of reality signifies a level of political maturity that is lacking in many other countries where officialdom prefers to stick its head in the sand.

Daniel also used the opportunity, shortly before leaving Dakar, to hold a press conference with a dozen Senegalese journalists to inform them of a recent study authored by Drs William Cheung, Reg Watson and himself, on global warming and fisheries, which implies a dire future for tropical fisheries. One of the workshop participants suggested to Daniel that the public should be “alerted, but not alarmed” by the trend that this paper describes and the implication for Senegalese fisheries. This point to alert people and not alarm them is an excellent formulation of our job as scientists, and luckily, the Senegalese journalists followed up on it. For those who speak French, you can verify that the Senegalese journalists got the point by reading this article published in Le Soleil Online (www.lesoleil.sn), as an example.

Daniel can also attest that Deng was a big success with the national dress that she was given by the participants (see picture, right)!

Climate change has impacted global fisheries for decades

CheungGraphic_web_editedA new paper from the Sea Around Us Project published in the journal Nature reveals that warmer ocean temperatures are driving marine species towards cooler, deeper waters, and this in turn, has affected global fisheries catches.

William Cheung, Reg Watson and Daniel Pauly used temperature preferences of fish and other marine species as a sort of “thermometer” to assess effects of climate change on the world’s oceans between 1970 and 2006. They found that global fisheries catches were increasingly dominated by warm-water species.
