Designate a Marine Protected Area and introduce some fishing restrictions (types unspecified) Subtidal Benthic Invertebrate Conservation

A replicated, site comparison study (year unspecified) of 28 sites across 14 rocky reef areas in the western Mediterranean Sea, Italy (Piazzi et al. 2016) found that protected areas with ‘low human pressures’ (restrictions unspecified) had similar overall invertebrate and algae community composition to unprotected areas with ‘high human pressures’, and similar invertebrate abundance. Community composition data were presented as graphical analyses. Percent cover of invertebrates was similar in protected (6.2%) and unprotected areas (3.7%). Invertebrates and algae were surveyed at two sites inside each of seven marine protected areas (fishing restrictions unspecified) and seven unprotected areas. All protected areas were established between 1997 and 1999 and reported to “preserve reefs from all human activities”. At 30–40 m depth, 10 plots (0.2 m2) were photographed at three 10 m2 locations/site. Invertebrates and algae species were identified and their % cover estimated from each photograph. Date of study unspecified.
