Fish Lab, Aquaria, and Marine Life in the Maldives

PLANKTON PRODUCTION

Our plankton and algae cultures are used as the main food source for the residents of our Fish Lab.

– Microalgae (Nannochloropsis) – Overall, 20L of algae were produced throughout the month.
– Rotifers – cultures remain stable, with no major changes in density or feeding routine. As population density was constant, food quantity per session has been kept to 2mL of Nannochloropsis microalgae, given 3 times per day.
– Brine shrimp (Artemia) – Artemia production continued daily during the month following the established protocol, with two separate batches maintained. One batch was used to feed jellyfish, shrimps, and fish, while the second was allocated to corals from the nursery system. Harvesting methods were further optimised, and feeding in the main tank was changed from Artemia cysts to live Artemia to provide a more suitable diet for the fish. Coral feeding remained at 3g per day, while the fish and jellyfish systems received 2.5g per day.

MOON JELLYFISH

In July, moon jellyfish were reintroduced into our main display cylindrical Kreisel tank. These jellyfish had been maintained in culture since April, progressing through the strobilation and juvenile growth stages until reaching 10cm in diameter. The jellyfish are regularly fed with Artemia to support their growth and development. A large stock of smaller jellyfish is being maintained in culture, and as they continue to grow, additional individuals will be transferred to the main tank.

GROUPER GROW-OUT (Epinephelus fuscoguttatus)

Land Aquaculture (Tanks) – groupers showed steady growth during the month, with the fish progressively increasing in size and biomass. Several of the larger individuals reached target size, resulting in eight groupers being delivered to Blue Restaurant for use in the dishes on the menu.

Groupers Ocean Culture (Sea Pen) – groupers continued to show good growth, with several individuals reaching larger sizes compared to the previous month. Following several stormy days, several groupers escaped from the sea pen.

AQUACULTURE – ‘SEAWEED’ AS A SUSTAINABLE FOOD

  • Microalgae (Spirulina platensis) – the culture remained stable, with a total stock culture of approximately 20L maintained as the inoculum. From this stock, 5L cultures were periodically established for harvesting, with a total of five harvest cycles completed to date. The harvested Spirulina was weighed as wet biomass initially, and then subsequently dehydrated to obtain the final dry weight. The culture has remained stable, allowing for regular production and harvesting. Spirulina was provided to the kitchen to assess its incorporation into potential preparations and to evaluate its suitability for use in the restaurant, with several tasting trials conducted during the month.
  • Sea Grapes (Caulerpa racemosa) – culture continues in our new Marine Landaa Garden growing system that we established in last month. We performed maintenance work to optimise growing conditions and improve the overall organisation and appearance of the cultivation area. Regular deliveries to the resort kitchen continued at 50g daily, with regular deliveries to Blu Restaurant, providing a monthly total of 2.65kg for culinary use. Biomass management will continue to be adjusted according to kitchen demand, ensuring a balance between sustainable production and operational needs.
  • Elkhorn Sea Moss (Kappaphycus alvarezii) – May’s cultivation continued growing during July, with the culture maintained in the sea pen adjacent to the grouper cage. Although the sea pen provides increased water circulation and greater depth, the algae continue to be affected by the presence of epiphytic organisms and grazing pressure from marine organisms.
  • Crunchy Hair Grass (Boodlea sp.) – The cultivation of Boodlea has been discontinued as the biomass weakened due to the reduction in light availability. In addition, the processing of this alga for kitchen use requires a significant amount of labour. Therefore, priority is given to the cultivation of our other algal species that are proving more suitable for kitchen applications.

Guest Excursions

At Kuda Huraa this month, a total of 257 guests enjoyed 43 different excursions to 7 different marine sites in the area, where we recorded 15 different megafauna species. 

At Landaa Giraavaru, we conducted 28 guided tours of our Marine Discovery Centre for a total of 90 guests representing 13 different nationalities. The USA represents the most guests (17 visitors, 3 tours) and also the highest number of children (6 kids). The average duration for a tour is approximately 25 minutes; the tours with more children tend to generate more questions and last longer.

Impressively, we conducted 26 guided snorkel excursions this month, enjoyed by 270 guests. Across 10 separate Dolphin Cruises for 147 guests, we recorded sightings of almost 1000 dolphins across 3 different species (spinners, bottlenose, Risso’s).

Summer Camp 2026

During the Landaa Giraavaru Summer Camp 2026, there have been coral-focused sessions delivered to guests giving, them the opportunity to learn about corals and build a coral frame. In total, we welcomed 17 participants across both sessions, with great interest in our Coral Restoration Project and the importance of protecting the Maldivian reefs. The Legends of this year’s Summer Camp receive a medium coral frame each, sponsored by Four Seasons, and forming a new reef that is dedicated to the Legends of today and tomorrow.

Junior Marine Savers

July was a busy month, teaching eager learners who were excited to dive into marine biology through coral, turtle and dolphin-based sessions. We enjoyed teaching a range of topics from the evolution of turtles and threats they face, or the life cycle of corals, to the fascinating lives of dolphins.
Kids then took part in feeding our turtle patients, building coral frames and identifying dolphins using Darwin software, before exploring the coral reef ecosystem at our channel site. These snorkel trips often provide exciting encounters with turtles, sharks, and an abundance of fish among the coral – it is always a pleasure to showcase the wonders below the water to curious youngsters.

Marine Discovery Centre Team

This month we welcomed Eve and Finn to our team. Eve is from the UK with a BSc in Marine Biology from Newcastle University. She spent two months as our Intern at Landaa Giraavaru, and made such a positive impression that she was promoted to a permanent position as Asst Coral Biologist at Kuda Huraa. Finn studied Biology at the University of Bristol, and he is excited to join our Marine Biology team to continue developing our Cetacean ID project.

We said goodbye to two valued members of our Marine Discovery Centre team: Olivia (Manager) and Rylee (Marine Biologist). Olivia has overseen the department throughout the past year; her presence will be sorely missed, and we wish her every success in the future. Rylee first joined as an intern before becoming our full-time Marine Biologist. She was a valuable team member, playing a key role in developing our dolphin ID project. She leaves us to pursue a Master’s in marine conservation.

We are also delighted to announce two promotions within our Marine Savers team. Katie is now our Manager of the Marine Discovery Centre, while Aditya has been promoted from Assistant to fully-fledged Coral Biologist. We congratulate them both on their new roles and look forward to seeing their continued contributions to our conservation projects.

Baa Atoll Marine Biology Internship (for Maldivians)

Our Baa Atoll Marine Biology Internship continued to inspire the next generation of marine conservationists through its staged learning programme.

Stage 1 – we welcomed 19 students and provided an introduction to the underwater world, offering a glimpse into the daily work of marine biologists in the Maldives. Through classroom sessions, hands-on activities, and exposure to marine conservation projects, participants gained a deeper appreciation for the marine environment and the diverse career opportunities available within the field.

Stage 3 – several ‘graduates’ from stages 1-2 returned to further develop their skills and knowledge. Participants had the opportunity to obtain their Open Water SCUBA certification, take a more active role in fieldwork, and engage in more in-depth classroom studies. The programme also introduced students to resort operations and the variety of career pathways available within the hospitality industry. The stage was a major success, with many students expressing strong enthusiasm for marine conservation and already enquiring about opportunities to join the official Four Seasons Hospitality Apprenticeship Programme in the future.

Maldives Sea Turtle Rescue & Rehabilitation

Turtle Rehabilitation… The End of an Era

As we close one of our most intense turtle-rescue seasons, we also say goodbye to some of the turtles that have shaped our rehabilitation centre. After having our rehabilitation centre at full capacity since December, we currently have only two turtles under our care, one of whom we hope to release very soon.

Unfortunately, this also means saying goodbye to two of our long-term patients. Zeus passed away at the end of June; we are currently working on preserving her skeleton for educational purposes, to demonstrate to visitors the devastating injuries that can be caused by boat propellers. At the end of July, we also lost Artemis, the soul of our rehabilitation centre, after more than five years in our care. Her loss truly marks the end of an era. She was not only one of the longest-standing residents of our centre, but also a true ambassador for sea turtle conservation. To us, she will always be the princess of our rehabilitation centre, winning the hearts of everyone who had the privilege of knowing her. Over the years, thousands of guests met Artemis and, through her story, gained a deeper understanding of the importance of protecting sea turtles and our oceans. Her legacy will live on through all those who were touched by her presence.

On a more positive note, June also brought two successful releases, with Athena and, finally, Toby returning to the ocean. This brings us to four successful releases in as many weeks, and marks the end of one of the busiest turtle rehabilitation seasons since the opening of our centre.

As we look ahead to the next season, we are also preparing several major improvements to the rehabilitation centre, with the goal of providing even better care and facilities for the patients that will arrive in the coming months. While this season has brought both unforgettable successes and heartbreaking losses, it has also reminded us why the work we do matters. We look forward to welcoming the next season with renewed energy, new improvements, and the hope of giving every turtle that arrives at our doors the best possible chance to return to the ocean.

Kaido was rescued back in January after being entangled in marine debris (‘ghost netting’). In this first update on Kaido’s journey, we are very happy to report that, after spending some time around the Maldives following his release, he soon began heading towards the waters of Sri Lanka, where an important feeding ground for Olive Ridley turtles is located. In less than a month, Kaido has already reached this area. We are delighted to see such promising progress and hope he continues to thrive and explore his new surroundings.

Valkyrie was also rescued back in January, and required an immediate flipper amputation after becoming entangled in a fishing line. Our three-flippered friend wasted no time setting course directly towards Sri Lankan waters. Although she was released after Kaido, she soon overtook him, and we wonder … did they meet up en route ? But she did not stop at Sri Lanka, and she currently appears to be heading towards Indonesia.
For turtles with an amputation, returning to the wild always presents an additional challenge, however, Val seems to have been more than ready for her return to the ocean. We are delighted to see her navigating the open sea with such confidence and look forward to following her journey.

For more indepth monthly reporting and a wider range of photos, you can visit our Four Seasons Team Diaries page over at Reefscapers.

At Kuda Huraa during July, we transplanted 11 new frames, kindly sponsored by guests and the Resort, and our team monitored (cleaned, repaired, photographed) a total of 111 existing coral frames at all sites around the island. We completed maintenance and monitoring across all four restoration sites around the island, with particular focus on the Blue Hole and House reef restoration sites, as well as Maw’s Rock.

At Landaa Giraavaru this month, we transplanted 35 new coral frames kindly sponsored by guests, the Resort, and online, adding ~1600 newly propagated coral fragments to Landaa’s House Reef (at a depth of 7m). We also monitored 145 existing frames, mainly at the Dive Site. Four Seasons sponsored 22 of these new frames (13 Build a Reef, 4 Managers’ Cocktails, 2 Media, 1 Staff Reef, 2 Special Large Frames). 12 frames were sponsored by in-house guests (8 Small, 1 Medium, 1 Large and 2 Heart Frames) and there was one online Heart Frame.

Baa Atoll Interns

Throughout July, our coral team welcomed the interns from across the atoll for the Baa Atoll Internship Programme, Stages 1 and 3. A total of 21 students in Stage 1 enjoyed a coral lecture to learn more details about these vital ecosystems, followed by the construction of a large coral frame sponsored by the Resort. Our 6 interns at Stage 3 helped with the collection of coral ‘fragments of opportunity’, and recycling frames through snorkelling and Scuba after completing their PADI Open Water Course. They also enjoyed a Coral ID presentation, followed by an in-water session identifying and photographing the coral species.
