Abstract

Site selection criteria, sample collection and analysis: The selection of suitable sites for the deployment of artificial reefs is a very important phase in the success of the reef functioning and efficiency. Following the primary and secondary stakeholders’ meetings, on the proposed dates of field sampling, the team of experts with the SCUBA team, ARSC members and active fishers with GPS sail on the pre-identified country boats or vessels, carrying all the sampling gears and anchors. They sail towards locations suggested by the fishermen, at distances of 2-5 km from the shore with a water depth of 7-25 m. The tidal parameters, amplitude, wave heights, wind speeds and local weather details are noted before sailing. A Global Positioning System (GPS) and sonar can be used along with scuba gear to locate the reef sites. The coordinates of the sampling sites are duly recorded separately by the fisher ARSC team members and the sampling team and corroborated to fix the sampling site.
