Help Give Sharks A Fighting Chance – Sign the Petition
Shark populations are devastated by overexploitation, including targeted fishing, bycatch and finning. Join thousands of AWARE divers and shark advocates who are serious about shark protection. Support the goal to reach 100,000 petition signatures from around the world by June 8th, World Ocean Day. Sign the petition and urge your friends and colleagues to do the same.
Together, we’re gaining the attention of policymakers worldwide. We’re closing loopholes in existing global shark management policies and insisting on full protections for Endangered and Critically Endangered sharks.
So far, the hotspot has skipped North Sulawesi Area. And with the the likely movement of the hotspot from North of Phillipines towards Palau, potentially, Bunaken will not be affected by the bleaching. However, it does not mean that the reef does not need our help.
the Philippines, Palau, and Guam.
In the same way that people who are in shape can fight and recover from disease, corals that are tough and healthy are more likely than weaker corals to survive stressful events, such as Acanthaster outbreak, or coral bleaching. Here are some sugestions that you can do as a dive operator.
1. Ask snorkelers and divers not to touch, step, or kick the corals. Make sure divers have good buoyancy and
that their dive equipment is securely attached. Consider keeping beginner divers at a distance from bleached corals.
2. Help maintain healthy populations of herbivorous reef fish, such as parrotfish, rabbitfish, surgeon fish, rudder fish, as well as sea urchins. Consider reducing the removal of these species. These creatures play an important role in removing algae, which can overgrow
areas of the reef that had mass mortality. Algae‐free areas are crucial for baby coral to settle and grow.
3. Be informed about the bleaching and the hotspot movement (in Indonesia, around April‐June, and October‐December). Help us to understand the extent of a bleaching event by informing us about the bleaching and non‐bleaching areas among your dive sites. Therefore we can have preliminary information on
which areas are stronger than others.
4. Help us to monitor the condition of affected and unaffected dive sites. Monitoring gives us clues about which areas recover better than others.
5. Help reefs to recover faster by stabilizing substrates through rehabilitation efforts.
6. Help authorities to enforce rules in the area.
7. Encourage your divers to actively reduce their greenhouse gas emissions.
This past Saturday January 29th, Two Fish Divers were invited by the Manado Jetski and Underwater Club in conjunction with the head of the regional police department to their Coral Re-Planting initiative. This great event was made to help contribute to preserving the coral growth in the area just in front of the Club which is a sandy bottom area. The event was a total success! The organization had a few events planned for the day: First, a Jetski race of about 12 jetski´s. Second, the main event: coral re-planting. For this event, approximately 75 divers registered in the main registration desk! And third: a big buffet style lunch with live music!
For coral re-planting, two 20 meters long (approx) of an artificial structure made with iron bars has been built along the slope to help stabilize the slope and to create a base which the coral fragments are tied to attach with the iron bars as the as the support base. Bits and pieces of broken yet living coral were collected for the replanting and restoration purposes. For this event, more than 10 species of coral (hard coral) were used and planted by all the participants teams. This effort has shown that within a month, there are significant changes from this efforts. More marine life can be seen underwater, seeking for food and shelter from the coral that has been planted around the area. We hope that a continuous coral replanting and observation as well monitoring will be taking place from time to time.
We would like to thank the Manado Jetski and Underwater Club for the invitation. Also, many thanks for their efforts to preserve and contribute to marine life, which represents a benefit to the environment and also to the local community (more tourism)
