“…Sea urchins have been wild harvested for at least six decades, with highest yields produced during the times when sushi became popular during the 1960s, however, most catches dropped dramatically following this period due to overexploitation (Stefańsson et al, 2017). Harvesting pressure to meet market demand led to over 40 species populations to overexploitation (Andrew et al, 2002;McBride, 2005) and there is pressure to identify other candidate species and to also rely more heavily on aquaculture production to meet this demand. In recent years new or emerging species have included the European Sea urchin species, Psammechinus miliaris (Suckling et al, 2011;Suckling et al, 2018;Suckling et al, 2020a;Suckling, 2021) and Sphaerechinus granularis (Joséet al, 2019), but there remain many species which have not yet been investigated for market potential.…”

Assessing the potential of the unexploited Atlantic purple sea urchin, Arbacia punctulata, for the edible market

The global demand for sea urchin as seafood is currently unmet. Despite exploitation of > 40 species across the world, there is a need to identify other candidate species, especially in regions where diversification in production is sought where species are considered native. The Eastern US presents an opportunity to determine the marketability of the currently unexploited Arbacia punctulata which is naturally distributed from Massachusetts and southwards into the Gulf of Mexico. To determine whether A. punctulata had market potential, it was fed one of the following diets to determine whether the gonad tissue (uni) could be manipulated to increase gonad mass and improve gonad color for the market: dried Ulva lactuca, Salmon pellets (Skretting), Tilapia pellets (Ziegler) or an Urchinomics diet designed for sea urchins either fed for 8 weeks or 12 weeks. All of the pelleted feeds (Salmon, Tilapia and Urchinomics) increased gonad mass and altered the color. The colors of the uni were generally darker than the colors that the market would typically prefer but some individuals did exhibit colors which have been classed as acceptable to the European market. This work highlights that further research is worthwhile to assess the market potential of A. punctulata.
