Impacts on FFE
The least studied impacts on FFE included noise pollution (14.28%) and EMFs (17.86%). Anthropogenic EMFs produced by subsea transmission cables can have detrimental and negligible impacts on the behavior and development of fish species. This spectrum includes decreased sperm mobility of Mediterranean mussels (Mytilus galloprovincialis) or increased foraging behavior of Little skates (Leucoraja erinacea). A species-specific understanding of EMF's impacts on FFE mainly exists; thus, continued research into the impact of EMF on California’s FFE is necessary. EMFs from a subsea cable in the San Francisco Bay Area produced no negative impact on salmon migrations. Floating wind turbines have a decreased presence in the water column compared to fixed-bottom turbines and may create less of an artificial reef. Artificial habitats become stable after 1.5–2 years in coastal areas of Japan and may take similarly as long to manifest in California.
