Resumo: | Sargassum muticum is a Japanese alga from the pheophycee class which has been introduced in Europe about fifteen years ago. It has greatly developed on account of its intrinsic characteristics (adaptation, growth speed, reproduction mode, etc...) and the favorable conditions it has encountered. The nuisance it generates can be very high but no efficient fighting solution has been found yet. Only mechanical means can be considered on a one off basis in areas where eradication is indispensable. Any development is faced with the problem of pick up costs. However the most interesting development for Sargassum muticum would be to utilize it as flocculent for suspended organic substances.  Location updates for Sargassum muticum in France in 1989 did not show any new stricken regions but the algae seem to rather spread within already hit areas. The Brittany coast is almost entirely stricken. On a World scale, new localisation has been reported in Sweden. Space born remote sensing by satellite seems to be an interesting way of studying littorals especially regarding seaweeds. Sargassum muticum can be localized on satellite images. Various imaging processing of the Morbihan gulf could lead to advantageous utilization of these algae all over that area.
