Two sponges from French Polynesia present a natural abundance allowing to envisage their exploitation. One of them, Dactylsopngia metachromia, has shown the presence of compounds of interest in human health. Its production must be perpetuated by its cultivation in order to guarantee its availability for the further development of molecules of interest. The ecophysiology of the sponge will be studied in order to optimize its culture. Crop tests will be followed among other parameters by the dosage of molecules of interest.

The second sponge, a species of the genus Haliclona even more frequent and abundant in French Polynesia, has so far provided no interesting molecule. However, research in other fields of valorization is being pursued.
