Further, these types of mariculture can also contribute to habitat restoration (Theuerkauf et al., 2019) and other important ecosystem and cultural services (Alleway et al., 2019; Gentry et al., 2020). Fisheries management approaches can include area-based measures, including bottom-trawling closures and essential fish habitat conservation areas. Boating, swimming, wading, and diving are prohibited within the conservation Diego-Scripps Coastal State Marine Conservation Area. We note that by definition MPAs have the conservation of nature as their explicit and primary goal (IUCN and WCPA, 2018). Communities, who were not consulted in these initial MPA designs, reacted so negatively to the proposed design that the attempt was terminated in 2002 (Scholz et al., 2004; Weible, 2008; Fox et al., 2013).
