Additional Information
This area of the island is a regular fishing spot for residents, as well as a popular dive and snorkel site. While we were conducting our cleanup dives, land-based fishermen arrived and started casting. Regular use seems to be the contributing factor.
discarded/sacrificial monofiliment fishing line tangles around the live coral heads, allowing algae growth on the filament itself, which then shadows/smothers the coral beneath it
Comments and Feedback
This information is for Dive 1 of 2 for International Coastal Cleanup Day. Thank you to our participants, not just our divers, but our snorkelers who provided surface support, shuttling debris back to the hard-working captain who did almost all of the sorting while the divers where down below! Huge Mahalo to everyone involved and to the owner of Extended Horizons for pulling the boat out of service for the day to enable this great event!
