Nekton sampling

Nekton surveys are performed using unbaited mesh fish traps placed in areas around the reef and a bare-bottom control site. Surveys are repeated three times a year and target the summer months when fish are most abundant. Traps are soaked for 48-72 hours. Upon recovery, species are removed, identified and measured. Data metrics used to assess habitat enhancement include total abundance (total number of individuals caught per trap), richness (total number of species found per trap), abundance of fishes, and abundance of decapods/crabs.
