Regional Impacts

Economic ImpactFisheries
Settlement of M. membrancea adversely affected the quality of kelp Saccharina longicruris during aquaculture trails in Gaspe, Quebec. Starting the cultures in the fall, and harvesting the kelp before the settlement of M. membranacea alleviated these problems (Gendron et al. 2010).
