In intertidal ecosystem, biotic (reproduction stage, algal growth, herbivory, epiphytism, fouling…) and abiotic (temperature, salinity, UV…) parameters are known to affect the algal species repartition. In response to this stresses, seaweeds are known to possess different chemical defense mechanisms by secondary metabolites production. The aim of this chapter is to understand coastal constraints and to present chemical defense strategies used by seaweeds.
