Artificial Reef Structures

bali volunteer marine reef conservation

North Bali Reef Conservation needs the support from international volunteers to help with its current projects. Volunteers can expect to help with constructing artificial reef structures, marine conservation education and helping to organise beach and reef cleans. Each volunteer will be able to build a personalised roti buaya structure, which will be deployed directly onto the reef. Volunteers with PADI diving qualifications would be useful but this is not necessary. There is an option to do clean up diving on the reef to remove any litter or even to help with coral transplantation. North Bali Reef Conservation also offers volunteers an opportunity to learn to dive and become qualified at an additional cost.

constructing artificial reef structuresAt North Bali Reef Conservation we are constructing an ongoing artificial reef where the natural reef has been destroyed. We are working with the members of the YBS fishermen team to help us construct and deploy these structures. This has created sustainable jobs within the local community and also provides fishermen with alternative incomes that would have otherwise been generated from extracting resources from the sea.

As a reef conservation organisation, our current main focus is building artificial reefs. We build and deploy many different designs of artificial reef units to provide a varied habitat for an optimal number of species. With help from our volunteers and local fishermen, we frequently deploy these units onto an area of previously destroyed reef, where they will provide new habitats for marine life. So far, we have built and deployed  over 3000 artificial reef structures.

These structures are placed on a sand bottom surveyed area along the coastline. Along the Tianyar coast, there are large flat sand bottomed plateaus, providing no habitat for fish and coral. The artificial reef structures we have deployed benefit the marine ecosystem in a variety of ways. The structures act as a substrate for coral larvae to attach while also providing a link between natural reef patches, improving connectivity by allowing individuals to move safely from one coral patch to another. Both structures facilitate coral growth and provide suitable egg laying habitats for reef fish while fish domes also provide protection from predators. In the future, corals will be transplanted from the natural reef onto the artificial reef.
