Comments and Feedback
Shortly after we entered the water we saw big bundled up abandoned fishing net that was stuck to a smaller coral (~60 cm in diameter) and floated upwards, about 1.5 m. There were several crabs and a fish trapped in it and seahorse (very rare sighting) was 'sitting' on a branch that was also trapped in this mess. First we cut the fish free then waited for the seashore to swim away. We were very worried that it would get trapped too. So we tried to position ourselves sort of in between the seashore and the fishing gear. Finally the seashore left. Then we carefully cut the fishing net off the coral, carried it to the shore. We cut out the two crabs that were still alive and released them back. We then continued with our dive. After the dive we disposed everything responsibly in clouding the huge mess of fishing net
