Top Siliceous Sponges Fishing Countries

Siliceous sponges, belonging to the class Demospongiae and Hexactinellida, are marine organisms characterized by their skeletons made of silica. While not a "fish" in the traditional sense, these sponges have historically been harvested for their use in cleaning, bathing, and as natural filters. The commercial fishing of siliceous sponges is relatively limited compared to other marine resources, but notable harvesting occurs in the Mediterranean Sea, the Caribbean, and parts of the Pacific. Greece, particularly the Dodecanese islands such as Kalymnos, has a long tradition of sponge diving, making it one of the top countries in this industry. Turkey, especially along its Aegean and Mediterranean coasts, is also a significant producer. Other important countries include Tunisia, Egypt, and Cuba, where local communities rely on traditional diving methods. In recent decades, the industry has faced challenges from overharvesting, disease, and the rise of synthetic alternatives, but artisanal sponge fishing remains an important cultural and economic activity in these regions.
