The low settlement of mussel Perna perna seeds on artificial collectors deployed on sea subsurface has been a major obstacle to the mussel farming improvement in Brazil. This study aimed to compare the seed settlement on artificial collectors deployed on the sea surface with the aid of buoys and at the subsurface (20 cm depth) in Cocanha Beach, Caraguatatuba City, Sao Paulo State, Brazil. Mann–Whitney test showed significant differences ( P < 0.05) between treatments for each class of length, with the best settlement occurring on the sea surface collectors for all classes ( P < 0.05). It is concluded that deploying artificial collectors with buoys on the sea surface increases the number and the biomass of settled mussel seeds when compared to the non‐buoys deployed collectors on the sea subsurface.
