We had a record number of 19 children The Six Senses Laamu team are excited to announce participating in the program throughout a new project starting in February. The team recently the month, completing 29 classes. received a Research Permit with the approval to further their coral spawning research in Laamu. Previously Fifteen graduated as full ‘Junior Marine the team have only been using visual observations Biologists’ and 11 completed additional during snorkel surveys to determine when different specialties, such as Fish Identification. species of coral spawn. With the new research permit, Congratulations to “Lewis” who completed we can now investigate the development of gametes, 11 classes, so far, the most accomplished which will give a much more accurate idea of when the Junior Marine Biologist of the entire corals will be ready to spawn. The study will be done in program. What a sen-sea-tional month! collaboration with coral spawning experts based at the Horniman Museum and Gardens in the U.K. Check out next month’s Blue & Green Laamu to see how we get on with the first month of data collection and how we do it! MEGAFAUNA ENCOUNTERS This month was a great kick start for MUI guest activities, with the team leading 1,013 guests on activities. In collaboration with Deep Blue Divers, the team lead 167 megafauna surveys, as every dive or snorkel from the resort is an opportunity for the teams to collect data on the larger marine animals within Laamu Atoll. For January alone, we recorded 329 turtle In January the MUI team hosted 1,013 guests through their sightings, 381 ray sightings and 751 shark activities, which was 23% of the guests staying at the resort. sightings! We will continue to monitoring megafauna sightings throughout the year to compare the results to the last full year An average of 11 megafauna were sighted on each of the of study in 2019. This will help us identify long term trends in the populations of these 167 dives and snorkels, including 751 sharks, 381 rays and animals. 329 turtles.

Until now, there were only two fisheries THREATENED GROUPER STOCKS with management plans in the country – livebait and grouper. The new plan comes This year started with some very good news alongside other new fishery plans for reef for the groupers in the Maldives. Groupers are fish, billfish, lobster, sea cucumber, marine vital for reef health; however, their stock has aquarium fish and diamondback squid. been declining in the Maldives for the past 40 years. This threatened fish family, will now have BLUE would like to thank the partners of additional safeguards under the new Grouper our ‘Grouper Fishery and Management’ Fishery Management Plan, including revised size project (2016-17); Six Senses Laamu, Laamu limits for the four most heavily targeted species: Atoll Council and UN’s Low Emission Climate Resilient Development Programme • Brown marbled grouper (60cm) (LECReD) and the interns who helped us • Camouflage grouper (40cm) with the grouper maturity studies. • Squaretail coral grouper (40cm) • Roving coral grouper (42cm) The new size limits, based on the data collected by the Maldives Marine Research Institute (MMRI) and Blue Marine Foundation (BLUE), are crucial UNDERSTANDING RESOURCE to give Maldivian groupers a fighting chance to reproduce and replenish their populations. USE IN LAAMU ATOLL Additional measures have also been introduced to Community participation and buy-in is an regulate fishing gear and destructive fishing practices, essential component of functional marine including a total ban on the use of pressurized air and reserves. BLUE is one step closer to assist the torches in association with guns. Use of spearguns to local community of Laamu to design their target spawning aggregations have also been banned. marine reserve network. During December and January our team and six interns from Shaha Hashim, Maldives Project Manager at BLUE, the Maldives National University (MNU) said: “Spawning aggregations are the sole opportunity travelled to 10 inhabited islands in the atoll to for groupers to reproduce.

More than 200 interviews have now and once gone, they are not known to recover. been completed and we have one more island Fishermen from across Maldives have reported that left to cover before we start writing our report. some aggregations have already disappeared. While Stay tuned for some fascinating insights into it is encouraging to see the timeframe extension of the resource use of Laamu Atoll! the five sites previously protected on paper, there is an urgent need to effectively protect at least one spawning site from each atoll of Maldives, if we are serious about managing our wild grouper stocks.” Marine Biology & Sustainability Newsletter Marine Biology & Sustainability Newsletter Six Senses Laamu 6 Six Senses Laamu 7 reported at one time, which guests were SURPRISE thrilled to observe from the boat and we were really excited to see the photos and videos from SURFACE FEEDING this trip. In the early months of recent years, we have been receiving reports of surface feeding mantas around this area specifically MANTAS so we plan to monitor this area more closely. In January, hosts and guests who joined on early The Manta Trust is hugely reliant upon JUNIOR MANTA morning fishing trips encountered surface feeding information from fisherman, resort staff and mantas around Kurethi, one of the local cleaning guests to help identify potential new manta RAY RESEARCHERS stations around Laamu. As many as 6 mantas were feeding and aggregation hotspots in Laamu. At the start of 2021, the Junior Marine Biology program was in full swing. Seven children joined Manta Trust researchers to take part in the manta specialty module where they learnt about the biology and ecology of manta rays, and the different aspects MANTA of research that are utilized by the Manta Trust team. They were excited to know more about our Stereo ENTANGLEMENT Video Photography (SVP) system in which two GoPro cameras are calibrated to measure the width PROTOCOLS of manta rays, in order to track their growth rate over time. They were also enthusiastic to know more about Remote Underwater Videography (RUV) methods, in We were heartbroken to learn about the which underwater cameras are left recording next to death of one of the identified Maldivian manta cleaning stations over multiple days to record mantas, Tambourine (M2801), who was found their presence and behavior when divers cannot entangled in a mooring line in Lhaviyani atoll. physically being there. Worryingly, this followed a similar incident in 2019 in Lhaviyani. After the first report, the Manta Trust team created an official guideline Alongside the classroom sessions, there were a few for “Mooring Line Entanglement Mitigation”, outdoor activities, such as making a sand sculpture of a in which industrial cable ties are attached life-size manta ray on the beach. The children were amazed along mooring lines, each at a 45-degree to discover the sheer size of mantas, and compare the size angle from the previous tie installed to create of a manta ray and a human.
