Residents of Shamiani village in Zanzibar’s Pemba Island are pioneering a sea cucumber ranching venture that protects vital coastal habitats while creating new income sources amid declining nearshore marine resources.
- Sea cucumber ranching in protected areas aims to revive marine habitats and incomes.
- High demand in Asian markets drives lucrative export opportunities.
- Community profit-sharing encourages sustainable management of local waters.
What happened
On Pemba Island, the coastal community of Shamiani has experienced a steady decline in fish and sea cucumber catches attributed to environmental stressors like warming waters and habitat degradation. In response, local residents collaborated with the Tanzanian aquaculture company Asili since 2022 to pilot sea cucumber ranching within designated protected shallow seagrass meadows. These zones are marked off to restrict fishing access, a move that followed extensive local discussions about long-term benefits and income distribution.
The initiative focuses on restocking sea cucumbers, a species once plentiful enough to support local livelihoods but now scarce, by cultivating them in these protected marine areas. This model not only aims to restore ecosystem health but also offers a sustainable way to generate income from these high-value marine animals, which are prized in Asian markets for culinary and medicinal uses. A revenue-sharing framework ensures that the communities who forego fishing access receive financial benefits from the venture.
Why it feels good
The sea cucumber farming project represents a hopeful example of how conservation and commerce can work hand in hand. It empowers the Shamiani community to actively protect their coastal environment while earning from a product that commands significant prices—fresh sea cucumbers can fetch $70 to $80 per kilogram locally, with higher returns possible through export. This model transforms conservation from a solely protective effort into one that directly supports community wellbeing.
Moreover, by fostering sustainable use of marine resources, the project provides a blueprint for other coastal communities facing similar declines due to overfishing and climate change. It demonstrates that when local voices guide the management of their environments alongside innovative business approaches, it is possible to balance ecological restoration with economic resilience in vulnerable coastal regions.
What to enjoy or watch next
As the pilot project in Shamiani develops, it will be important to monitor both its ecological impact and economic viability. Expansion could include targeting emerging markets, such as nutraceuticals derived from processed sea cucumber products, adding further value beyond fresh seafood exports. Continued community involvement and transparent profit-sharing will be key to maintaining local support and ensuring the marine ecosystems recover sustainably.
Stakeholders and observers can also watch how this model might be adapted to other coastal sites facing similar challenges across East Africa and beyond. Success here might inspire broader adoption of mariculture solutions that blend environment and income generation, helping coastal communities navigate the pressures of global demand for marine products alongside the urgent need for conservation.
