Designate a Marine Protected Area with a zonation system of activity restrictions
A replicated, randomized, controlled study in 2008–2012 of nine rocky reef sites inside a marine park in Shark Bay, Indian Ocean, southeastern New South Wales, Australia (Wootton et al. 2012) found that five years after designating a marine park with various levels of fishing restrictions, the abundance of blacklip abalone Haliotis rubra was higher in sites with full fishing prohibition compared to those with partial prohibition and compared to sites outside the park (all fishing allowed). There were more abalone in sites with full fishing prohibition (4.3 individuals/transect) compared to sites with partial prohibition (0.9) and sites outside the park (1.9). In 2007, a marine park was established which included zones where all fishing was prohibited, and zones with partial prohibition (commercial fishing prohibited but recreational fishing and harvesting allowed). Twice annually between 2008 and 2012, samples were collected at nine randomly selected sites: three within each prohibition level inside the park, three outside the park where all fishing is allowed. Three 30 m transects/site were randomly deployed at 1–3 m depth, and abundance of blacklip abalone estimated from one 1 m strip/transect.
