Top Marine Shells Not Elsewhere Included Fishing Countries

"Marine shells not elsewhere included" (NEI) refers to a diverse group of marine mollusks—such as whelks, conchs, topshells, and other gastropods and bivalves—that are not classified under more specific shellfish categories in international fisheries statistics. These species are harvested for their edible meat, ornamental shells, and sometimes for industrial uses. The leading countries in the capture and export of NEI marine shells include China, Vietnam, Thailand, the Philippines, and Indonesia. These nations have long coastlines, rich marine biodiversity, and established traditions of small-scale and artisanal shellfish harvesting. The industry supports coastal livelihoods and local economies, with products often destined for both domestic consumption and international markets, especially in Asia. However, overfishing and habitat degradation are concerns, prompting some countries to introduce management measures to ensure sustainability.
