Type of Debris fishing net
Comments The small crab was inside the 6 lbs. fishing net.

The area is a living community of people relying on the ocean for livelihood. Among the debris collected was a 6 lbs. fishing net and multiple fishing lines. The area is also a host to many small boats servicing tourists. Some of the debris collected are likely the trash from the daily operations and even the maintenance of these boats.

We are not happy to report that we have collected a metal can paint with some residue epoxy coating paint still in it. In fact it stained the equipment (mostly the wetsuit) of one participant. We didn't notice it was still leaking residue paint. We have also collected wooden fragments from a paintbrush. We have also collected a very big fishing net.

Paint cans with residue - highly likely to be toxic to underwater life

Fishing net - hazard to marine life

wet wipes - tends to cover a the surface area of corals and affects the life of these corals
