Green Sea Turtles hatchlings on Kuredu

Guests at Kuredu Resort recently had a very cute surprise in the sand: a green sea turtle nest hatched! Late in the evening, while walking back to their villa, the guests spotted the tiny turtles making their way quickly across the beach into the ocean. A few hatchlings wandered astray and were collected by resort staff, soon to be released under the supervision of resident Sea Turtle Biologist, Stephanie, along with volunteers from the Prodivers Team.

According to previous reports, it takes green turtle nests 49 to 62 days to hatch here in the Maldives, but the baby turtles on Kuredu were a little slower – it took them 64 days to make their way out of the nest.

To evaluate the hatching success of the nest, Stephanie and a volunteer digging team from Prodivers went to exhume the nest 48 hours after the hatching event. After quite some digging, they successfully discovered the nest and out of 105 eggs laid, only three had failed to develop – that’s 102 more baby green turtles in the ocean! Such a successful nest is great news for the sea turtle population and we hope to see some of the hatchlings back on Kuredu to nest in about 10 to 15 years’ time.

Snorkelling or scuba diving at Kuredu Island Resort Maldives gives a very good chance of seeing turtles – the island is blessed with a large community of green sea turtles that can be seen at Caves, either on a Prodivers snorkelling excursion or dive trip. Turtles can also be spotted grazing in the lagoon.

Common crabs encountered in the Maldives: Part 2

Crabs are an underappreciated species. Whilst living in a harsh and arid environment they dedicate their lives to keeping the beach pristine.

Swift-Footed Rock Crab

The swift-footed rock crab can easily go unnoticed due to its elusive behaviour. It inhabits rocky shores at mid to high tide level and so can be found around beach rocks, boat ramps, rock walls and jetties. These crabs are fast moving and are generally only seen at night, unless disturbed. Then you may observe them jumping from rock to rock trying to find a new refuge.

Their colouration can be mesmerising with a multitude of blue, green, purple, orange, white and black. The crabs encountered on Gili are more blue, green and purple with white stripes. The shell (carapace) can be up to eight centimeters wide and is flattened, compared to other crabs which have shells that are more rounded.

The crab feeds on algae, detritus, small vertebrates, barnacles, limpets and snails. They use their claws to break into the shells of other animals and to tear off pieces of their prey to be transferred into their mouth. This species is predated upon by a variety of animals including birds, octopus and fish, so it isn’t safe for them in the ocean or out of it!

Fiddler crabs

Fiddler crabs are a small and short lived species of crab (up to two years) and are closely related to ghost crabs. They are found in mangroves, brackish water, mud flats, lagoons and swamps. The colouration of the crabs change in correlation with circadian rhythm – during the day they are dark and at night they are light.

Fiddler crabs are well known for their sexual dimorphism – the male’s major claw is much larger than the females. If the large claw has been lost the male will develop a new large claw on the opposite side, which will appear after molting. The female’s claws are the same size. The crabs use their claws in communication, courtship and combat. The male claw is used in waving displays which signals to the female that they are ready to mate. A more vigorous waving display indicates a healthier male and a larger claw indicates a wider burrow which will provide better temperatures for egg incubation. Females chose their partners based on claw size and the quality of waving. Once a female has been attracted she will reside in the male’s burrow whilst the eggs are being laid. The female will carry her eggs on the underside of her body for a two week gestation period. After this period the female will venture out of the burrow and release the larvae into a receding tide.

During feeding the crabs move their smaller claw from the ground to their mouth. This movement looks like the crab is playing the smaller claw like a fiddle – hence the name, fiddler crab. The smaller claw is used to pick up the sediment which is then sifted through in the crab’s mouth. Algae, microbes and fungus are the preferred diet of the crab. After the nutrients are extracted the sediment is placed back onto the ground in a ball. The feeding habits may play a vital role in preserving the ecosystem as they aerate the soil. The fiddler crab can be seen when visiting local islands, especially in the mangrove area at low tide

Common crabs encountered in the Maldives: Part 1

Crabs are an underappreciated species. Whilst living in a harsh and arid environment they dedicate their lives to keeping the beach pristine.

The Maldives is rich in life and biodiversity, but the majority of this diversity is marine based. Due to the great distance of the Maldives from large land masses there are relatively few land based species. Crabs, are one of the most common. These shy little critters are abundant, entertaining to observe and vital to the island’s survival.

Land Hermit Crabs

Land hermit crabs are completely adapted to life on land, living under leaf litter or in other sheltered areas. A common error made by people is completely submerging these crabs in water, mistaking them for marine animals. Unfortunately hermit crabs can only survive for a few minutes when completely submerged. They are not true crabs because they do not have their own shell. Instead they use shells from dead gastropods in order to protect their soft abdomens. They are a long lived species – sometimes reaching the age of 40 years and older – so they go through a lot of shells!

Hermit crabs start their lives moving through a variety of larval stages whilst floating in the ocean. The larvae spend the first 40 – 60 days of their life alongside plankton until they change into a hermit crab/lobster shape. In this final larval stage they find a small shell and over the period of a month will spend more time on land until they finally molt and leave the ocean for good. By feeding on vegetation, insects, detritus, other smaller hermit crabs and microbes in the sand the crab grows in size. To accommodate this growth their hard exoskeleton must be shed periodically during the year and this process will carry on through-out the hermit crab’s life. As they grow in size the hermit crab molts less frequently and the molt process takes longer, during which time the crab will stay completely submerged in the sand.

When sexually mature the male will knock on the female’s shell to signal mating. Both genders will then extend out of their shells and the male will fertilise the female. After fertilisation the female will carry her eggs around on her abdomen where they are protected from predation. The bigger the female the larger the quantity of eggs. After one month the eggs are fully developed and the colour of the egg will have changed from brick red to grey. To hatch the eggs the female will enter the water at low tide. Upon contact with water the eggs burst open and the larvae are released.

Ghost Crab

Another common crab species is the ghost crab which is aptly named due to its nocturnal activity and sandy colouration, making the crab perfectly camouflaged into the beach backdrop. These crabs are found on sandy beaches and live in burrows. The narrower and shorter the burrow the smaller the crab. Their burrows serve a number of purposes: protection from predation, storage of their food, protection from drying out and other extreme weather conditions as well as a place to mate (although not all ghost crabs mate in burrows).

Young crabs and female crabs create burrows with sand scattered everywhere, with young crabs preferring to create burrows nearer to the water, whilst male crabs have burrows with a neat mound of sand outside – the larger the crab the larger the mound. Males produce mating sounds, squeaking noises, in a variety of ways; by rubbing their right claw on their leg, by rubbing their legs together, or by using their gill chambers, which they keep moist with saltwater.

After mating the females store thousands of eggs inside an abdominal flap. She will then venture into the sea when the eggs are ready to hatch. Since ghost crabs cannot swim the female will float upside down in the water allowing the eggs in her abdomen to breathe. Upon contact with saltwater the larvae are released and after two months return to land.

Swift-Footed Rock Crab. Picture by Laura Pola

The exoskeleton of a ghost crab is water tight, which prevents the crab from drying out in the arid and salty conditions on the beach. All ghost crabs have eye stalks with the males additionally having horns. These eyestalks enable the crab to see in any direction and can be stored in groves on their shells. The ghost crab’s eye sight is so good that they are able to catch insects’ mid-flight. They also have a well-developed sense of smell. They are very agile, capable of moving at 10mph, which makes them the fastest of all crustaceans.

Due to the erratic nature of their food supply ghost crabs are very protective of their food and will use their claws in combat displays. Male ghost crabs have one claw that is slightly larger than the other and combat is normally non-contact and ritualistic. Ghost crabs spend the majority of their day looking for food and particularly like to eat fish, seaweed, microbes in the sand, jellyfish, other crabs, snails, turtle hatchings and really anything they can get their claws on.

Maldives plastic recycling on a local islands

Gili Lankanfushi conserves our limited resources and cleans up our islands to help preserve our future.

Following the success of plastic recycling on Gili Lankanfushi we took the leap and expanded our project. On November 2nd Gili Lankanfushi visited Himmafushi, a local island and a big producer of plastic waste due to their plastic water bottle factory. With the assistance of the local NGO Parley, who are spearheading plastic recycling in the Maldives our aim was to implement a plastic recycling project at the school and expand this throughout the island. Together with Parley, the teachers and local council members in attendance Gili Lankanfushi conducted a 30 minute presentation including two activities which all the children participated in. The presentation was well received and the council were positive regarding expanding recycling to all areas of the island. After the school visit 50 staff from Gili Lankanfushi conducted an island plastic clean to demonstrate how easy it is to recycle plastic and what types of plastic can be recycled. A huge amount of plastic was collected and on seeing this the Himmafushi local community has also become inspired to recycle their plastic waste. Gili Lankanfushi will remain in close contact with Himmafushi and offer support and guidance when needed.

 Throughout August 2017 on Gili Lankanfushi 280 hosts attended the sustainability training. Host mentally regarding plastic pollution, water, electricity and food waste has now changed for the better. In addition to Gili Lankanfushi’s plastic presentation Maai Rasheed from Parley visited and conducted a presentation about plastic recycling. Hosts can now be seen regularly recycling their plastic and helping with island cleans – for example the recent Himmafushi clean.

 Following the training activities aimed at increasing host water and electricity use awareness, hosts now know how to reduce wasting these resources through enhanced understanding of water and electricity requirements of common activities. They were given top energy and water saving tips, for example using the fan over the AC, turning off electrical appliances, washing full loads in the washing machine at a low temperature – 20°C, air drying clothing, turning off lights, having shorter showers, only using a small amount of water when cleaning, turning the tap off when brushing teeth, shaving and soaping up. You can make these changes too!

Raising awareness about excessive water waste

 Over the coming months plastic recycling, food waste, electricity and water use will be monitored. In the near future we will host a no bin day in the canteen which will teach hosts about portion and waste control. We have already observed a decrease in water use – before training the average host would use 200L of water per day – this is now reduced to 160L. We are confident that hosts will continue to reduce the waste of resources and participate in plastic recycling.

Things you should know if you are travelling to the Maldives on a budget

This blog has several parts, next week read about money and taxes……

With the advent of local island guesthouses and low cost flight carriers there has never been a more affordable time to travel to the Maldives. At Male International airport it is becoming a far more common sight to see guests arriving with backpacks and not matching Louis Vuitton luggage. These travellers are here to experience a destination previously perceived to be only for those seeking luxury. So maybe it’s time you considered putting the Maldives on your travel map!

Whilst budget travel in the Maldives is a growing sector of the tourism industry there still remains limited information available for would be travelers and backpackers. So the team at Secret Paradise put our heads together to provide what we feel are the Top 10 tips every budget traveler should be aware of.

Clearing Immigration and security

To enter the Maldives no pre-arrival visa is required, a thirty day free visa is issued on arrival to all nationalities, provided the following conditions are met:

Be holding a valid passport (requires to be valid for 6 months from date of arrival) and have a valid ticket to continue your journey out of the Maldives

Confirmation of a reservation in a tourist resort or a hotel either in the form of a hotel voucher or online reservation and have enough funds to cover the expenses for the duration of your stay (US$100 + $50 dollars per day)

The right to refuse entry lies at the discretion of the Immigration official, so make it easier for yourself and organise your accommodation prior to your arrival. Online sites such as Booking.Com, Airbnb and Trip Advisor are a great place to start or if you are looking for more of an experience and not just accommodation contact Secret Paradise.

Once you have cleared immigration, collect your luggage and enter the arrivals hall where a representative of the guesthouse or resort should be waiting for you. Importing goods such as alcohol, pork items, pornography, idols of worship and narcotics into the Maldives is strictly forbidden. To make life easier declare the Buddha that you have purchased in Sri Lanka and the bottle of vodka picked up in duty free, the authorities will hold any items declared or undeclared for you to collect as you depart at the end of your stay.

Coral Reef Research at Gili Lankanfushi Maldives

We encourage scientists to visit Gili Lankanfushi to share their knowledge with the Marine Biology team and carry out in-depth research of our local environment.

In an ever changing world, research is an important method of tracking environmental fluctuations and sharing information about our surroundings. After the coral bleaching event of 2016, Gili Lankanfushi wanted to learn more about the damage caused to our beautiful house reef. We hosted a team of experts funded by Rufford Small Grants Foundation, Chiara Pisapia, Dr Morgan Pratchett, and Deborah Burn who assessed the changes on the reef.  They focused on coral cover, coral size, and the number of young corals that have grown on the reef since the bleaching. Morgan Pratchett, the leading expert in Crown of Thorns Starfish (COTS) Ancanthaster planci, also monitored the size, sex and distribution of COTS.

 

The team carried out an initial study in the Maldives in 2016 and then returned to the same sites in 2017 in order to carefully assess any changes in their original findings.  On Gili Lankanfushi’s house reef, the team carried out line surveys at five and ten metres along the drop off and found that after the bleaching, coral cover has dropped to 6% at five metres and 2% at ten metres. This low coral cover is predominantly due to the ocean warming event in addition to COTS predation. Yet, in comparison with other study sites, Gili Lankanfushi had a higher number of coral recruits than expected which means new coral is beginning to grow again on the shallow section of our reef. This results from the hard work of Gili’s Team.

Dr Morgan Pratchett, collected data on COTS around the resort.  Despite their beautiful appearance, COTS are far less captivating once you understand the threat they pose to a struggling reef. They eat the remaining hard corals and new coral recruits. Over the past year, their population has spiked into an ‘outbreak’ therefore they have to be removed from the reef and our team works tirelessly to find each individual. Morgan brought COTS to Gili Veshi, our Marine Biology Lab, to teach us techniques on how to better understand these starfish. By dissecting individuals Morgan was able to show our team the interior of each specimen and explain if the animal was well fed or reproductive.  We were able to highlight certain features under the microscope.  We found the starfish living on our house reef were starving and not yet reproducing which leads us to believe the outbreak is over.

 

The aim of monitoring our house reef over time is to predict and track recovery of different species. We are extremely grateful to the knowledge shared by Chiara, Morgan and Deborah hope they can visit the resort again in 2018 to assess how much our reef has recovered.  We look forward to their return.

Crown of Thorns Eradication

As the corals of the Maldives are already vulnerable our understanding and removal efforts of the crown of thorns starfish is paramount to the health of our reef.

Everyday Gili Lankanfushi has sightings of the voracious crown-of-thorns starfish (COT) Acanthaster planci. Native to coral reefs in the Indo-Pacific region and the largest species of starfish (Asteroidea), they are generally seen at depths of up to 30 metres. However, they have also been known to travel between Atolls at great depths of around 200m. There are four species of COT, but it is A. planci which is responsible for coral mortality in the Northern Indian Ocean and the coral triangle. COTS are corallivores and during optimal conditions can grow to over half a meter in diameter and have more than 30 arms.

Crown of Thorns

Generally COTS can be considered a keystone species because they can maintain healthy coral reef diversity by primarily feeding on fast growing corals, such as staghorn and plate (Acropora sp.) and enable the slower massive corals to establish and develop. When coral coverage is low, often resulting from COT outbreaks, COTS will eat PoritesMontipora, sponges, algae and encrusting organisms. One COT can consume all the coral in a 6 to 10m square radius annually, so the impact on an already vulnerable reef is catastrophic. The feeding behaviour is dependent on population density, water motion and species composition. COTS are covered in venomous spines coated with saponin which causes irritation and pain at a puncture wound. The spines are long, sharp and lowered to avoid drag.

Fossil evidence suggests that COTS developed millions of years ago. However, COT outbreaks have only occurred in the last 60 to 70 years and with increasing frequency and intensity. The first recorded outbreak occurred in the 1950s in the Ryukyu Islands off Japan. Combined with anthropogenic threats and other stresses outbreaks are greatly detrimental to coral reef survival and the fish associated with the reef.

Crown of Thorns destruction: 1 – healthy coral, 2 – freshly killed coral, 3 – recently killed portion colonised by algae and bacteria, 4 – long dead coral

COT outbreaks in the Maldives are relatively recent; the first recorded outbreak was in the 1970’s, the second in the 1990’s. Currently we are experiencing an outbreak which started in 2013. It began in North Male Atoll and has spread through to Ari Atoll, Baa Atoll, Lhaviyani Atoll, South Male Atoll and large densities have recently been documented in Shaviyani Atoll.

Outbreaks result for a variety of reasons. Firstly, when there is an excess of nutrients entering the water as a consequence of runoff from sewage, fertiliser and other island practices. The resulting eutrophication leads to increased plankton for the COT larvae and decreased juvenile mortality. Secondly, loss of COT predators; napoleon wrasse, lined worm, harlequin shrimp, starry puffer fish, titan and yellow margin triggerfish and triton’s trumpet (red and spangled emperor and parrotfish have been known to feed off young COTS before they have spines).

COT being predated upon by Triton’s Trumpet.

Loss of predators occurs due to overfishing for the souvenir trade, bycatch and habitat destruction. This leads to a drop in already low predation pressure and results in a COT population surge. Finally, COTS have excellent adaptations as they are resilient organisms with an selected life history (high growth rate, typically exploit less crowded ecological niches and produce many off spring). COT females can produce 65 million eggs annually between October to February. The eggs are released into the water column and are fertilized by clouds of sperm from nearby males. After fertilisation larvae are in their planktonic form and remain that way for weeks. After settling on the sea floor and developing into their adult form they develop their spines and start feeding off coral. This process can take around a year. COTS are most vulnerable before their spines are developed. Additionally, they can survive between 6 to 9 months without food, and body parts lost due to stress or predation can regenerate within 6 months.

Short and long term methods are being established around the world to minimise the effects of current outbreaks and to help prevent future outbreaks. The marine biology team at Gili Lankanfushi is focused on the removal of COTS. Our primary aim is removing these creatures from the overwater villas and jetty’s. Guests and hosts report sightings of COTS, and our team of marine biologists will remove them by injecting them with vinegar. This method is labour intensive and is carried out as regularly as possible by both the Marine Biology team and the Dive Centre.

To eat or not to eat

As our understanding of the ocean grows, more people want to know where their food is coming from and how it landed on their plate. 

Global fisheries have been under pressure in recent decades due to the technological advancement of fishing fleets. We are now able to catch more fish at a faster rate and for some fish populations, this has resulted in dire consequences. They are not able to repopulate at a fast enough rate to combat declining numbers.

International research projects allow us to identify which fish species need special attention and which we can eat within reason.  A movement has come about in recent years to help educate consumers and fishermen about which species should not or should be fished or consumed. With this knowledge, families and business are able to make sustainable choices when they buy their fish.  They can chose to only purchase sustainable fish species that have been sustainably caught.

So what are sustainable fish? They are fish that are caught in a way that the vitality of the species and the environment is not being harmed in the long term.

There are two main factors which determine whether a fishery is sustainable: how healthy the population is and the method of catch. Some fishing methods such as bottom trawling, are very destructive as they plough up the ocean floor, others are indiscriminate and catch more than just the fish species they are targeting.

With fishing being the second largest industry in the Maldives after tourism, it is easy to see why overfishing has started to become a problem here. Fishing has always been a part of Maldivian culture, like President Maumoon Abdul Gayoom said: “Fishing is the lifeblood of our nation”, the problem only started to become bigger, as export and tourism started growing

The most unsustainable fish on the market in the Maldives today are Bluefin Tuna, Tropical prawns, Marlin, Sharks, Skates, Rays and Eels. To try to reduce the loss of species in the Maldives, certain laws surrounding catch and fishing techniques have been introduced to enable sustainable fishing. One is the pole and line method, which involves individuals catching tuna with a single line. Many young fishermen have taken up this technique as they have seen their stocks diminish and want to take sustainable action.  One of the most over fished species in the Maldives is Yellowfin Tuna, so by catching the tuna one-by-one, with a pole and line, the number of tuna caught is reduced and other marine life is not being harmed in the process.

The International Pole and Line Foundation (IPNLF) supports local communities in the Maldives. Due to the fisheries act of 1987, Maldivian tuna fisheries now follow the pole and line regulations. This fishery is hailed as the most successful MSC certified pole-and-line tuna fishery in the world. At Gili Lankanfushi, we also strive to eat only sustainably caught, sustainable species. We only accept Bonito Tuna, Dogtooth Tuna, White Tuna, Job Fish, Rainbow runner, Jack fish, Trevally, Mackerel, Emperor Fish, Wahoo, Red Snapper and Yellow Snapper from our local fishermen.

So how can you help? You can make a concerted effort to buy sustainable seafood which can be found on the Marine Stewardship Council certified products list, or simply ask for a certificate or proof of the fish you are buying’s origin. You can also spread the word about buying only sustainable fish to as many people as you can.

Just remember:  You have the right to ask your fish supplier or fish monger where your fish came from and how it was caught. If you are not completely satisfied with the answer, do not buy the fish!

Colonies of Hope

Blog written by guest blogger and marine biologist Clare Baranowski

Preserving coral reefs is a growing concern in the Maldives

At Gili Lankanfushi, we are recovering our coral reefs through the Coral lines Project. By growing small fragments of coral on hanging ropes (lines) and then transplanting them to our house reef near One Palm Island, we hope to see regeneration and aim to kick start the health of our house reef.

Our Coral Lines Project started three years ago and currently holds around 7484 coral colonies. We are consistently adding small fragments of coral to the already growing population on 153 lines.

Josie monitoring our 153 coral lines

The vulnerable nature of coral populations mean that they undergo cycles of disturbance and recovery. Our house reef was affected by warmer waters created by the El Nino event in 2016 which bleached much of the corals. Yet against all odds, most fragments in our coral lines nursery survived.  They have also been faced with a Crown of Thorns (coral predators) outbreak this year and have still remained intact.

In some cases, the corals in our lines are no longer present on shallow reefs in the area.

Now, is the perfect time to begin stage two of our coral restoration project by moving coral from our nursery to our house reef.  Transplanting coral is a delicate procedure with a lot of trial and error. We began slowly by creating a test site with a small number of coral colonies to ensure we would not lose healthy coral unnecessarily.

Josie beginning the process

We found a site with conditions not too dissimilar to the nursery. The area had to be flat and solid, with no loose material and space for growth.  It also had to be an area that is easily accessible for monitoring, but nowhere in danger of tampering or accidental damage.  We chose a depth of 8 metres in the middle of house reef drop off where we regularly snorkel. Another major concern was the Crown of Thorns Starfish, so we placed the coral in an area visited regularly by Harvey Edwards, Ocean Paradise Dive Centre manager, who has been removing these starfish from the reef for months.

Clare cutting the coral from the line

The next step was to cut the colonies from the lines in the nursery, and transport them in mesh bags in the water. We decided to use three different Acropora species to begin with as they are fast growing and like a lot of light and a moderate current. Once at the site, we cleaned the area of algae and attached the coral to ensure protection from extreme water movement. We placed them an equal distance apart to allow quick growth and attached the coral using epoxy, which is a clay like cement. We were aware from previous studies that Miliput (epoxy clay) has been seen to kill the part of the coral it is attaching, so we placed small amounts of putty at the base of the coral.

Once a week, for a total of six weeks, we will measure growth and survivorship of the coral.  We hope to replicate the test at different depths and locations to find a suitable site to start a larger restoration project. However, we will hold off on most of the major transplantation until after the monsoon season.

Attaching the colonies using epoxy

Due to the fragility of coral species, our rehabilitation plans are very flexible, and subject to a long monitoring period.  We expect to adapt our approach and long term management to ensure we keep up with the changing environment of the reef. Previous restoration plans have been hindered by external threats, so we are so excited to finally begin this project. We will be producing scientific data along the way which we hope will contribute to current coral reef rehabilitation knowledge.

Although our transplants are working well so far, we will still have many question to answer in the future such as: are the corals on the house reef still reproducing? As these corals survived the last bleaching, will they be more genetically suited to future hostile conditions? The answers to these questions are all just a work in progress and we will have to keep on watching and learning as we replant and monitor these corals over the next few years. As our house reef sustained a lot of mortality and the coral cover is low, we hope that this new project will help to rejuvenate the reef and raise awareness.

PADI’s guest blogger Clare Baranowski introduces herself:

I am a marine zoologist from the UK who has worked throughout the tropics researching mega fauna and reef ecosystems in the Caribbean and Indian Ocean. I have experience monitoring and restoring coral and surveying manta, turtle and dolphin populations. I began my career as a science communicator before moving into research and management roles, this is why I incorporate outreach and education into every project I work on and I hope to continue this at Gili Lankanfushi.
