  1. Designate a Marine Protected Area and introduce some fishing restrictions (types unspecified)

    A replicated, site comparison study in 2008 of 21 sites in seven coral reefs areas across the inner islands of the Seychelles, Indian Ocean (Cariglia et al. 2013) found that sea cucumbers (thirteen species combined) tended to be more abundant inside marine protected areas prohibiting some fishing (exact restrictions unspecified) compared to adjacent fished areas. Seventy-six percent of all sea cucumbers (thirteen species combined) were found within protected areas. The average abundance of sea cucumbers appeared higher in protected areas (2/154 m2), compared to fished areas (0/154 m2), although no statistical test was reported. The probability of finding sea cucumbers was reported to be higher in protected areas (79%), compared to fished areas (48%). In April, divers counted sea cucumbers in three protected areas (established >20 years prior; date unspecified) and four unprotected areas (three sites/area) within sixteen 154 m2 circles/site.
