SUSTAINABILITY & ISLAND CONSERVATION 

Map_Cozumel.jpg

Cozumel is a worldwide top destination for scuba diving widely known for its endless visibility and stunning coral reefs. Hundreds of species of animal and coral depend on the health of the reef for their survival. It is our responsibility as divers and guests in the underwater world to take any and all measures we can to protect this environment.

Our goal at Aldora Divers is to allow our customers to experience this stunning environment

without causing any harm to its fragile ecosystem.

We want to remind our divers that coral and marine life are protected in Cozumel, they should not be touched, collected or damaged due to our presence there. 

Cozumel's Marine Park

cozumel-marine-park.jpg

Cozumel's Marine Park runs south along the west cost of the island starting at the dive site Pariaso around Punta Sur, the southern tip of the island, and up north along the East side of the island. Approximately 1.8 million people visit Cozumel's Marine Park every year and the area is protected by Mexican federal law. According to figures from Mexico's National Commission for Protected Natural Areas (CONANP), its waters are currently home to 105 different types of coral and 262 species of fish.

When visiting for your dive vacation please remember to follow the marine park rules.

Rules of Cozumel's Marine Park

Aldora Divers Marine_Park_Rules

We ask all of our customers to be aware of their use of Sunscreen when in Cozumel. It is advised that sunscreen not be used when diving or snorkelling in the Marine Park as there are many reef damaging chemicals contained in sunscreen. Even the packaged 'REEF SAFE' sunscreen is usually not suitable and still contains the reef damaging chemicals.

We encourage our customers to cover up in the sun, use a hat and wear a rash vest to protect your skin, however, If sunscreen must be used please make sure it is a Zinc Based sunscreen and that it contains none of the harmful chemicals listed below. 

Aldora Divers Suncreen Use

Annual Reef Closure Rotation

Cozumel's Marine Park has implemented a rotation of reef closures throughout the year to allow the reef to rest from divers and increased boat traffic. 

Please view the chart below detailing what reefs are closed throughout the year.

MASTER BUOYANCY CONTROL

Help us protect the reef by making sure you have no reef contact and no bottom contact while diving. Learn how to dive correctly in the current, our Divemasters will be happy to teach you correct weighting and buoyany techniques.

PHOTOGRAPHERS

Take care when trying to get that perfect shot. By having perfect buoyancy control you will get the shot without harming the environment around you. Please do not chase the marine life in order to get your pictures, with less movement the animals will come to you and everyone can enjoy the interaction.

Make better food choices

Protect our Sharks, Rays, Turtles, Pink Conch (Caracol) Lobster (especially during mating season) and Grouper by not eating them in local restaurants. Instead choose Snapper, Hogfish and Lionfish.

Aldora Sustainable Courses

We offer some distinct courses and dives to help with conservation practices on the island.

Lionfish Hunting

Learn how to use a Hawaiian sling and to safely hunt the invasive species, making sure not to damage the reef and surrounding areas. 

AWARE - Dive against Debris

A trash cleaning dive usually in a northern dive site. Here we use specific tools to cut, clean and collect fishing line which has become entangled in the reef, while making sure to not harm the coral and organisms that have been caught up in the line in the process.  

Eagle Ray Monitoring

In the winter months sightings of Eagle Rays are more common in the marine park. Learn how to identify males and females and how to correctly photograph the eagle rays to help with monitoring projects.

What can you do to help? 
Use your camera!

Due to the stony coral tissue loss disease that has ravaged Cozumel's reefs, hard coral species are in local danger of extinction. A gene bank of these endangered corals is being created to design future restoration projects to save these species of coral.

We need your help to report healthy colonies of the corals listed below with photographs

and their GPS location to the email listed below.

rescatecorales@gmail.com

If GPS location cannot be listed, please use the dive site name and the depth at which you found the coral.

Volunteer Projcts

Aldora Divers in association with: 
Volunteer and Civil Projects

On Cozumel, there are a number of Volunteer Civil Projects that divers can independently join to help with conservation efforts on the island.

Cozumel Ocean Research is a non for profit non-govermental organization that runs various scientific research projects, some of which are centered around emblematic species that inhabit or migrate to the island, others focus on pollution concerns and industry pressure to this same environment. Their projects are dedicated to the collection of valuable data through which we may supply proposals that support the conservation of specific species and habitats.

Mar Sustentable is a non profit organisation who's aim is to generate and integrate interdisciplinary data on coastal exploitation and socioecological systems to integrate the ecological, social, archaeological, and physical dimensions of coastal environments. They aim to produce trajectories of human coastal exploitation on different temporal and spatial scales over critical conservation habitats (e.g., coral reefs, mangroves) and have worked closely with Aldora divers collecting shark research.

CONANP Cozumel- Parque Nacional Arrecifes de Cozumel y APFF Isla Cozumel has been working at collecting samples of hard coral that is under threat on the Island and replanting them in various locations along the coast. Aldora assists CONANP in trips to the north east side of the Island to visit the colonies of Elkhorn Coral there where they have now been sucessfully tagged and listed. 

Corales Vivos Cozumel is a self-organized community group that emerged in 2019 in response to the accelerated death of reef-building corals and the degradation of this ecosystem. Members of the Cozumel community organized themselves and began working hand in hand with CONANP Cozumel to monitor the disease known as white syndrome or SCTLD. This included training its members to monitor corals, algae and fish. Since its beginnings, Corales Vivos Cozumel has also conducted surveillance to detect environmental violations and report them to the authorities.

Aldora divers works directly with Corales vivos in providing support to the marine park and north zone coral nurseries.

Comite de Vigilancia logo JPEG.jpg

Aldora Divers, a prominent figure in the diving community, proudly announces its role as one of the founders and active members of the Community Surveillance and Monitoring Committee. This committee, comprised of five dedicated dive shops, is committed to the vigilant oversight and elimination of illegal fishing activities within the Arrecifes de Cozumel National Marine Park.

The committee engages in regular surveillance patrols, both by sea and land.

These patrols are conducted to monitor and discourage any unauthorised fishing activities that could compromise the integrity of the marine park
