Top Trochus Shells Not Elsewhere Included Fishing Countries

Trochus shells, primarily from the species *Trochus niloticus*, are marine gastropods valued for their lustrous mother-of-pearl, which is used in buttons, jewelry, and decorative items. The "Top Trochus Shells Not Elsewhere Included" category refers to trochus shell fisheries not classified under other specific shellfish categories. Major countries involved in harvesting trochus shells include Indonesia, the Philippines, Papua New Guinea, and several Pacific Island nations such as Fiji, Vanuatu, and the Solomon Islands. These countries have long traditions of trochus shell collection, often by hand or free diving in shallow coral reefs. The industry is typically small-scale and community-based, providing important income for coastal populations. Sustainable management is crucial, as overharvesting can threaten local populations and reef ecosystems. International trade in trochus shells is regulated in some regions to ensure resource sustainability and protect local livelihoods.
