Sea urchin gonads (called uni) are highly valued in seafood markets, creating demand for sustainable production. In Seychelles, small-scale farming of Tripneustes gratilla is promising, but costly pelleted feeds for gonad enhancement limit feasibility. This study evaluated alternative fresh feeds, Sargassum spp., carrots (Daucus carota), moringa (Moringa oleifera), and a mixed diet, over 10 weeks using 200 T. gratilla (average...

Stable tropical conditions and a near-pristine marine environment in the Seychelles suggest a high potential for seaweed aquaculture to supply growing global markets for sustainable marine products. The aims of this study were to assess the mercury content in five seaweed species that are candidates for aquaculture in Seychelles: Gracilaria cortica, Gracilaria salicornia, Caulerpa racemosa, Sargassum spp., and Asparagopsis tax...

Asparagopsis taxiformis macroalgae can potentially reduce methane emissions when fed to ruminants, thus reducing the emission of greenhouse gasses into the atmosphere. Literature indicates water temperatures above 24 °C limit A. taxiformes growth rates during culture, however, it grows wild in Seychelles where water temperatures range from 25 to 31.5 °C. The feasibility of cultivating the local strain of A. taxiformis in Seych...
