Résumé :	On the North-Western Mediterranean coastline, the genus Cystoseira (Fucales) has a key role on upper infralittoral community structure. Cystoseira amentacea var. stricta and C. compressa are the most common superficial Cystoseira species. In this area, the coastline is subjected to a strong anthropogenic pressure which has caused severe Cystoseira population decreases. The present study consists in the development of a cheap and easy to use transplantation technique of C amentacea var. stricta and C compressa in order to either restore. former natural populations or help their settlement on artificial substrates. The thalli were fixed with epoxy glue in holes made by a drill. The success of the technique was assessed by counting the number of remaining transplanted thalli after 3 weeks, 3 months and 6 months. Results were found encouraging with 75% of survival for both species after 6 months. Moreover fertile fronds were observed on the transplanted thalli showing the harmlessness of the technique.
