"Erect sea moss" is not a fish species, but rather a type of red seaweed (algae) scientifically known as *Chondrus crispus*, commonly called Irish moss or carrageen moss. This marine plant is harvested primarily for its use in food, cosmetics, and pharmaceuticals due to its high carrageenan content, a natural thickener. The leading countries in erect sea moss (Irish moss) harvesting are Ireland and Canada, particularly in the Atlantic provinces such as Nova Scotia and New Brunswick. Other significant producers include France, Spain, and some coastal regions in the United States. The industry is characterized by both wild harvesting and aquaculture, with local communities relying on traditional hand-raking methods as well as more modern, sustainable farming techniques. The global demand for sea moss continues to grow, driven by its popularity as a health supplement and food additive.
