The flagship of MareVivo’s seafood production, the Castrense Mussel is the result of extensive experience in the field—combining the latest mussel farming technologies with the knowledge gained over 30 years in close contact with the sea.
The entire farming process of the Castrense Mussel (Mytilus galloprovincialis) is carried out with full respect for the marine habitat, with particular care given to the mussel’s natural growth, as it filters nutrients directly from the water columns of the Bay of Castro.
This stretch of water, off the Adriatic coast of Salento, thanks to the sea’s purity and the abundance of phytoplankton and mineral salts, gives the Castrense its unique qualities that make it unmistakable on the palate.
The innovative offshore farm complies with the strictest bio-sustainability standards and, in fact, provides a positive contribution to the marine environment by encouraging the natural reproduction of local fish species. Its anchoring system features holes that serve as shelters for fish, inviting them to settle.
Our commitment to environmental protection in the cultivation of the Castrense Mussel has earned us an important recognition from the international organization “Friend of the Sea”, which awards bio-sustainable seafood production following rigorous audits.
