Prince Edward Island (PEI) mussels are grown along the coasts of Prince Edward Island, Canada which is just off the coast of Nova Scotia. The island is separated from Nova Scotia by the Northumberland Strait and it sits in the Gulf of St. Lawrence. Prince Edward Island is the smallest, greenest providence in Canada and produces our smallest mussel. The PEI mussel can only be grown to 2.5 inches and if it gets any larger than that it will not open. It reaches market size in 18 months to 3 years depending on the food available in the water. The quality of PEI mussels is assured by the industry’s advanced technology and through the joint shellfish monitoring programs conducted by the provincial and federal governments.
