Additional Information
Restricted movement of civilian, small scale, fishing population due to extended periods of rough weather. Particularly a series on continuous anti-cyclones influencing local air pressure. Civid-19 lockdown and economic pressure may also have contributed towards the fishing traps falling into disrepair.
Nothing to report.
Fishing traps coated in plastic to prevent salt water from reacting with the steel. The practice is wide-spread and cages are abandoned once broken.
Comments and Feedback
Debris volume has reduced greatly since last cleanup. Aside from fishing waste, no other debris was present in the area inspected. The site location being in a fishing village the above was to be expected.
