    A preliminary value chain analysis of shark fisheries in Madagascar 2014
    Also available in:
    No results found.

    Madagascar’s extensive (~6,500 km) coastline comprises the most diverse and extensive shallow marine habitats in the Western Indian Ocean, supporting an estimated 123 shark and ray species. Sharks have featured in Madagascar’s fisheries for at least 100 years, with exports recorded as early as the 1920’s. Globally, shark fins are one of the most highly valued seafood items and represent a critical and significant source of cash for some of Madagascar’s isolated fishing communities. The global sh ark fin trade is estimated to be worth between US$400-500 million a year. Increases in the shark trade over the last two decades is closely linked to economic growth in China, where the market is concentrated, and the ripple effects of this increase in demand have been felt worldwide. Scientific estimates for the number of sharks killed annually can be up to 100 million individuals and sharks are on the whole overexploited. Today, thirty percent of all shark and ray species are now classified as ‘Threatened’ or ‘Near Threatened’ with extinction according to the IUCN Red List, although this number is likely to be higher given that the status of almost half (47%) of shark species cannot be scientifically assessed due to a lack of data. There is strong evidence that shark overexploitation occurs in Malagasy waters and that shark populations in the area are declining rapidly. Although reliable figures on Madagascar’s domestic shark fishery are sparse, anecdotal observations report declines in shark numbers within the last two decades. According to national studies based only on official export data, recorded shark fin exports stood at approximately 32 tonnes in 2010, a decrease from 65 tonnes in 1994. Lack of data on catches, particularly from artisanal fisheries, bycatch by licensed industrial vessels, and by illegal, unregulated and unreported (IUU) fishing by foreign industrial vessels, means these official export figures are likely to be gross underestimates of the actual pro duction. Madagascar’s shark fishery is comprised of three main fisheries according to Malagasy legislation: artisanal, traditional and industrial fisheries. Madagascar’s artisanal and traditional shark fisheries extend along the entire west coast, with the most important traditional fisheries along the southwest coast. Overfishing has led to fisher migration, spreading the fishery along the entire west coast and also much of the north. There is no established traditional shark fishery along the east coast due to adverse sea conditions, whilst the south is the least developed of all sites surveyed for this report. Throughout the country, surveyed fishers report catching shark for the purposes of income from selling fins (88%) and meat (77%), and as a source of food (31%), demonstrating the important link to the international shark fin trade. Shark fin exports reach the international market mostly through two principal buyers and exporters, namely the Sea Reine and Sin Hing, Chinese comp anies based in Antananarivo. The supply chain for shark fins is both complex and rather fluid with fishers selling either fresh (wet) or dried fins to collectors and fins graded in value according to size and quality. Some fishers bypass the local collectors and sell dried fins directly to main buyers in larger towns to obtain a better price, which can be a mark-up of 40% for high quality fins. The value of shark fins during the study period (2012) varies according to their condition (wet or dri ed), quality (four recognised grades) and their position in the supply chain. Robust data was collected for the first two levels of the supply chain but was lacking for the higher levels (main buyer to exporter). Guitarfish fins were on the whole, twice as valuable as shark fins and therefore both in demand and a fishing target. Since 2012 the average value of shark fins has dropped. Trade in shark meat is also well establishedin Madagascar, with meat sold into a supply chain that serves mainly local and national (provincial) markets but can also be exported to the Comoros. Shark meat does not fetch a high price compared to other fish or meats but can be an important supplementary source of income or nutrition in some cases. Generally fresh meat is sold and consumed locally whilst dried salted meat is bought by collectors and transported to inland urban markets in Madagascar. Some dried shark meat is also exported.

Almost none of the sharks caught are landed in Madagascar. IUU fishing within Madagascar’s Exclusive Economic Zone (EEZ) is a well-established issue, with the shark fishery specifically targeted by both licensed and unlicenced vessels. Despite the significant pressures on Madagascar’s shark fishery and the enormous socio-ecological and economic value of the trade, the country has no coherent or functioning shark conservation strategy or legislation. The lack of a national strategy is largely due to deficiencies in data on fishing effort, catches, landings and discards in all commercial fisheries for sh ark. This is compounded by a paucity of information on shark ecology, fisheries status and the socioeconomic value of the trade throughout Madagascar. Furthermore, in isolated coastal areas with little infrastructure, the sale of high value dried shark fins has been one of the few ways local Malagasy fishermen can earn cash. In this context, the diverse and unconnected stakeholders have no basis or motivation to enact meaningful conservation measures, particularly when economic imperatives outwe igh any other consideration. In a country as poor as Madagascar, even minor poverty relief is important, leading fishers to continue shark fishing despite low catches and diminishing returns for fishing effort, further threatening the future of the fishery. There is an urgent need to actively and aggressively manage Madagascar’s shark fishery. The rapid decline of sharks is likely to have several negative socioeconomic and ecological impacts, including the loss of livelihoods and protein for tho se people who rely on them and potentially altering the trophic structure of marine and coastal ecosystems. However, putting in place conservation measures and enforcing regulations remains a formidable challenge. Much of Madagascar’s fishery takes place in remote fishing grounds scattered over thousands of kilometres of coastline; the fishers are highly mobile and move great distances to seek productive fishing grounds; the government lacks the means to monitor these fisheries and enforce regul ations; and the markets are informal and closed. Significant steps must be taken in order to effectively prevent the collapse of Madagascar’s shark fishery. A widespread campaign to regulate both international and local shark fishing must occur simultaneously for any significant positive change to occur. For this to take place scientifically robust data must be collected over the long term. For any national conservation strategies to be implemented effectively, they should be based on data colle cted through participative monitoring and implemented at the national level. Such strategies should apply to artisanal and traditional fisheries, as well as to international commercial fishing vessels operating within the EEZ. Madagascar’s existing locally-managed marine areas are a vehicle through which coastal shark management strategies could be implemented. However an increase in both technical and logistical capacity will be required for effective management at the local, regional and natio nal level, together with strong enforcement support to LMMAs. Although it is recommended that the government develops appropriate national legislation and put in place proper monitoring and export restrictions, the onus remains heavily on the international community, with global legislation driving the regulation or lack of regulation of the global shark trade. Particular attention needs to be paid to those countries with distant water fleets / vessels operating within Madagascar’s EEZ, both leg ally and illegally. Without proper regulation of their shark fishing effort, partly through RFMO’s, little progress can be made.

    Restoration of productive aquatic ecosystems by small-scale fisheries and aquaculture communities in Asia
    Good practices, innovations and success stories

    This report showcases examples of actions taken by small-scale fishers and aquaculture farmers in Asia to restore the productivity of aquatic ecosystems. Small-scale fishers and fish farmers include some of the world’s most marginalized and impoverished people groups, yet their harvests account for over half of the world’s aquatic food production. The marine, coastal and freshwater ecosystems their livelihoods depend upon are degraded from human impacts and further at risk from climate change. Ecosystem restoration actions by fisherfolk communities can revitalize the socio-ecological services and sustain progress over time. Both passive and active restoration approaches are being employed across Asia’s marine, coastal and inland waterways. Fishers, fish farmers, and fishworkers’ restorative actions are focused on increasing the sustainability of their operations. Common approaches include eliminating destructive fishing, reducing overfishing through gear changes and effort control, restoring connectivity of floodplains and fish migration pathways, integrated aquaculture and rice-farming practices, re-stocking of native fisheries, and actively rehabilitating and / or re-establishing habitats. Progress is measurable through a diverse array of environmental, socio-economic and governance related metrics. Changes in fisheries catches, ecological connectivity, water quality, habitat diversity and structure, and fish consumption provide important measures of biodiversity gains (or losses). Common enablers of success include economic incentives, co-management and legal recognition of fishing rights, highly engaged fisherfolk cooperatives or community groups, women’s leadership and development, and community partnerships with stakeholders that focus on enabling fisherfolk’s own goals for sustainable livelihoods. Ecosystem restoration activities have not lasted when these enablers are insufficiently attended to and when environmental aspects of project feasibility, such as the choice of rehabilitation locations and / or species, are poorly planned. Successes in ecosystem restoration by fisherfolk can and are being scaled out to neighbouring communities and countries. Key to this is the sharing of stories, lessons learned and tools through south-south partnerships, learning exchanges, and women’s groups. Simple, low-cost tools and actions have enabled long-term engagement by small-scale fishers in sustainable operations. More complex actions, such as the uptake of integrated aquaculture systems, are also enabling stepwise changes in ecosystem restoration. By sharing stories from different ecosystems, fisheries, and geographies, this report seeks to help fisherfolk and their partners glean from one another and achieve faster progress in ecosystem restoration.

    Improving governance of aquaculture employment: a global assessment 2014
    Also available in:

    Effective governance of modern aquaculture must reconcile ecological and human wellbeing so that the industry is sustainable over time. Without effective governance, there will be misallocation of resources, and perhaps stagnation of the industry, irreversible environmental damage, and social unrest. An important component of human wellbeing is the treatment of the workers in the industry. The aim of this study, which was recommended by FAO Members during the Fourth Session of the FAO COFI Sub- Committee on Aquaculture held in Puerto Varas, Chile, in 2008, is to contribute to the understanding of governance in aquaculture employment so as to suggest potential improvements where necessary. A dozen farms and jurisdictions in Africa, the Americas, Asia and Europe were reviewed for their employment practices. Information on employment characteristics, such as educational background, gender and remuneration, was obtained from farms by survey. The aim is to evaluate whether workers in aquacu lture are treated according to the law, and are paid at a rate equal to those in similar sectors. The creation of employment appears to be a decisive factor in public perceptions of the aquaculture industry, as indicated in attitudinal studies. The conclusions of this report suggest that aquaculture has benefited the overall socio-economic conditions of the areas in which it operates. The industry has provided jobs, particularly non-seasonal jobs. These have enabled young people to stay in their communities, enhancing the economic viability of isolated areas. Total remuneration levels in all of the enterprises surveyed were at, or above, the minimum wage, and usually above wages in alternative sectors. Farms also provided indirect benefits, such as medical and pension coverage, and in some cases, bonuses. Attitudinal surveys indicate that these benefits are appreciated by the local population. However, there are negative aspects. Wages of unskilled workers in fish processing are low an d working conditions often rudimentary. The dominance of large companies in areas of high unemployment can create a dualistic labour market that is reflected in wages; professionals are paid competitive salaries, but unskilled workers less than the value of their revenue product. There is also the danger that labour laws are either poorly enforced or, where violated, result in fines that lack deterrence, perhaps because governments wish to retain a competitive advantage for their internationally traded species. A number of suggestions are made that would improve the governance of labour in aquaculture. Because of the relatively long time that elapsed between the compilation of the information reported in this document and its publication, the situation may have improved here or there. Therefore, these suggestions may not be needed there. However, they remain relevant where such is not the case or for countries thriving to develop aquaculture in a sustainable manner. Note should be take n that this study does not intend to pinpoint any specific country or aquaculture system; its goal is to use them as case studies for the purpose of generating lessons, positive or negative, to learn from.
