“…The degradation of seagrasses leads to the depreciation of resources that are dependent on them; therefore, seagrass restoration as a way to restore fisheries is a scientifically viable option [37]. This study, together with the previous studies carried out in the study areas, paved the way for seagrass restoration [35,49] and documentation towards seagrass management [50]. The authors of [50], who compared both coastal and inland areas in west and central African fisheries, highlighted the modeled value chains to underpin social issues, actors that can support the desired sustainability of fisheries, and an analogy for the case of Guidwane within IB underpinning several functional social, economic, and environmental issues.…”

Seagrass Invertebrate Fisheries, Their Value Chains and the Role of LMMAs in Sustainability of the Coastal Communities—Case of Southern Mozambique

Invertebrate gleaning within seagrass meadows is a common activity across eastern African communities that depend on fisheries for their livelihoods. Based on a case study of two contrasting sites, Maputo Bay (MB) and Inhambane Bay (IB),this study documents, both qualitatively and quantitatively, the gleaning activity, its value chain and stakeholders,payingparticular attention to the recently created Locally Managed Marine Areas (LMMAs) within IB, boasting creativity in seagrass invertebrate fishery management.Twenty-four common edible species were identified for MB, and 15 for IB; nearly all gleaners were women and children. Our estimates indicate that about 7.7 and 7.6 tons of invertebrates are collected in the peak catch weeks (spring low tides) in MB and IB, respectively. Resources are caught and sold at local markets, food fairs (for IB only), and restaurants,as well as for direct household consumption. One thousand one hundred and seventy two(1172) hectares of LMMAs (corresponding to nearly 0.05 of IB) of fisheries management, together with existing community and other stakeholder engagement and intervention on value chains, are at the center of tangible invertebrate fishery management.

“…In Senegal, the quantities of fish exported are much higher than the quantities supplied on the local market. In The Gambia, the same problem arises with a local availability of fish that is gradually decreasing (Acosta-Alba et al, 2022). This explains that there are large fluctuations in individual consumption of small pelagics.…”

Contribution of small-scale migrant fishing to the emergence of the fishmeal industry in West Africa: Cases of Mauritania, Senegal and the Gambia

The objective of this article is to present the contribution of migrant fishers to the supply of fishmeal factories in Senegal, The Gambia and Mauritania. The method consisted first of identifying migrant fishers and then quantifying the volumes of small pelagic fish they catch in the three countries studied. Then, an interview guide was submitted to more than 250 actors (migrant fishers and fishmongers) met in Banjul and Serrekunda in the Gambia, in Nouakchott and Nouadhibou in Mauritania, and in the fishing, centers located on the small Senegalese coast. These individual and collective interviews made it possible to estimate and determine the share of migrant fishers’ catches allocated to the fishmeal industry. Overall, the four groups of migrant fishers (3 Senegalese and 1 Guinean) identified in Mauritania and The Gambia catch on average more than 305,000 tonnes of pelagic fish per year over the period 2015 - 2018. Analysis of the marketing of their catches shows that almost 63% of the 305,000 tonnes, i.e. 192,000 tonnes of pelagic fish, are destined to supply the fishmeal factories of the three countries studied, while only 113,000 tonnes are distributed on the national consumer markets (fresh and artisanal processed). Of the 192,000 tonnes destined for fishmeal factories, two-thirds are sent to Mauritanian factories, with Senegal and The Gambia sharing the remaining third. Thus, important collaborations have been established in recent years between migrant fishers and the fishmeal industries. Indeed, the fishmeal industries improve the operating accounts of migrant fishers by ensuring the sale of their catches at more remunerative prices than on the local market at the micro level. However, when analyzed on a large scale, fishmeal industries exert a real pressure on the nutritional security of West African countries, as pelagic fish are the main source of animal protein in Senegal and The Gambia and have been over exploited in recent years. In addition, they prevent access to artisanal processing of their raw material. All these elements raise the question of the urgency of regulating migrant fishers catches on a regional scale and drastically reducing the share allocated to fishmeal processing in favor of local consumption.

“…Considering the above-cited finding, a low number of harvesters receiving information could be the reason for setup violation, as well as the inexistence of alternative livelihood activities. Intervention in livelihoods needs to tackle value chains, vulnerabilities especially related to gender, wider socio-economic issues including local rights, and base of given environment, seascape or habitats [23,24].…”

This study evaluates gleaning exclusion as an approach for the rehabilitation of seagrass ecosystems and as an option for important intertidal resource management that contributes to the social well-being of communities. The monitoring of seagrass plant and invertebrate recovery after the implementation of gleaning exclusion was conducted over 50 plots of 5 m × 5 m each, which were settled in the seagrass meadow of NW Maputo Bay, Mozambique. The exclusion experiment was designed to compensate for the important loss of seagrass in the area due to gleaning activity characterized mainly by digging and revolving sediments to collect mostly clams. Results showed that, in general, seagrass plant shoot density started having significant positive recovery after five months: three months for Halophila ovalis, five months for Halodule uninvervis, and much more time (>six months) for the IUCN Red List endangered Zostera capensis. For invertebrates, 194 individual invertebrates were collected belonging to 13 species. Solen cylindraceus was the most dominant edible invertebrate species in the local community, and Dosinia hepatica for non-edible species. The result of the experiment showed a positive recovery in the abundance and diversity of invertebrates. The results support previous findings, suggesting that the installation of a no-take zone can enhance the health of an ecosystem. Therefore, to limit the violation and conflicts of the no-take zones, the creation of alternative activities for harvesters and the flexibility of restrictions are vital. Further investigation should be considered to obtain an effective management of the zones, including documentation of species, gleaning practices, and an effective restoration of seagrass meadows.
