Marine conservation in the Indian Ocean

Published

Introduced by Jeff Goodman

Each year more people look for exotic destinations to take their holidays and dive trips and so the human impact on these pristine places takes a terrible toll. Reef destruction, over fishing, uncontrolled development, pollution from human waste… the list is almost endless. So who is ultimately responsible? Local government? Tour operators? Resort companies? Tourists? We all tend to pass the buck while at the same time making as much profit as possible before the golden goose eventually gets choked to death. In the Maldives at least, these issues are starting to be being taken seriously.

The Maldives, called “the flower of the Indies” by Marco polo, is suffering today from new developments and an increased population, including tourism, which together with climate change will synergistically impact on the marine environment.

The Maldives constitutes together with the Laccadives the largest and most extensive chain of atolls on the planet with less than 4% of the territory being dry land, so by joining the two most important forces that drive the country together, conservation and tourism, a long term sustainability of the marine environment can be obtained.

This country is the most imminently threatened by rising seas caused by climate change, so the Maldives has to be prepared for climate change as past emissions will increase global temperatures by up to 0.60º C over the next four decades, so not only must our awareness of climate change increase, so must our need to understand the changes it will bring and our vulnerability to it. Other activities practiced in the Maldives such as coral mining, pollution and unregulated fishing are already impacting on the marine environment, so understanding the effects of temperature increase and ocean acidification is of extreme importance.

A country that is no longer relying on their tuna fishery for survival but depend on resort islands and incoming tourists for their livelihoods have to take care of their environment.

Speaking about the tourism in Male, Kuoni’s Head of Corporate Responsibility Matthias Leisinger once said that “tourism is like fire; you can cook with it, but it can also burn your house down.” The tourism industry generates about 30% of the country´s GDP. In 1998 a bleaching event caused almost 100 percent of mortality in some areas of the coral reefs and, compared to other countries where management was working really well, their recovery was much better than in the Maldives. “Incidents like this are likely to increase as stock diminishes everywhere” says another representative from the Ministry of Tourism in the Maldives. He also pointed out new challenges arising with the changing market profile of tourism in the country, since the European visitors do form part of taking care of the natural environment. However, “the market is changing, and the new market is constituted of guests that are walking on the reefs, catching and eating crabs….” “Maybe it is about time for the resorts “to take responsibility for the natural environment for the duration for the lease,” a representative from the Marine Research Centre (MRC) said. Adjustment is essential if the different sectors, including tourism, aim to reduce the vulnerability to climate change and limit its negative sides and so optimizing the resources to the local community to cope with these changes.

           The two biggest threats to the Maldives are climate change and waste management.

             Climate change and coral reefs resilience

            ● Coral Reefs in the Maldives

– The Maldives is home to around 60 different coral genera and has the highest coral diversity in the Indian Ocean. Perhaps due to its substratum or erupted lava, the Maldivian reefs appear to be qualitatively different from other shallow reefs in the Indian Ocean in the way that they are composed of branching Acropora in high abundance and diversity. The Maldives also have the highest temperatures of the Indian Ocean.

– The threats the coral reefs are facing in the Maldives are sedimentation and sewage stress from the bigger islands (from the harbors and airport). In addition to this, inappropriate fishing methodologies are increasing and impact the recovery rate of the reef from bleaching events, and together with the global climate change is the biggest threat nowadays. The impact and the long-term possible recovery of reefs are directly related to overall health of coral reefs.

–  For local and national managers to be able to act in response to these threats it is therefore of extreme importance to have monitoring protocols.

Monitoring Protocols

A number of protocols have been developed by the Marine Research Center, the Darwin Initiative, and the Great Barrier Marine Park Authority to monitor reef fisheries and coral bleaching in which corals expel the algal cells (zooxanthellae), that under normal conditions live within their tissue. The Maldives has already experienced extensive climate related damage to their reefs, where other reefs recovered better under similar circumstances, therefore an accurate management and understanding of Coral Reef health has to be implemented around the whole country.

Bleach Watch

This protocol has been developed to detect and measure conditions and events of coral bleaching from a wide range of users like dive operators and resort staff, who over time can prepare available, reliable reports. Detecting early signs of mass bleaching events require a wide network of observers over a broad span of territory.

CPC

Counting the coral coverage and the coral diversity across the Maldives over time will provide the national government and resort managers with valuable information which can be used to understand and act in response to observed changes and threats to coral reef around the Maldives.

Reef Fisheries and the Darwin Reef Fish Project  

It is important for the Maldives to obtain more knowledge about reef and fisheries in order to develop new management plans to maintain the Coral Reef’s health. The reef fish are important through herb ivory and predation and both overfishing and destructive fishing practices can alter the dynamics of the whole ecosystem. The Darwin Reef Fish Initiative together with the MRC have developed a new resources management plan, where spawning aggregations and fish home range can be detected to elaborate new management plans. The aquarium and bait fishery have guidelines, but there are no regulations for reef fish, apart from the protected Napoleon wrasse and parrotfish species. The reef fishery has to be managed properly to be sustainable and size limitations of reef fish are necessary, so by implementing this monitoring protocol, miss-reporting and under-reporting fish, like the Rainbow runner, is being sampled and measured to apply appropriate managing guidelines and so improve the resilience of the Coral Reefs.

Fish watch

A fish count and underwater visual census; it constitutes a tool to measure fish populations over time and location.

Fish Catch

A survey collecting information on number and weight of landed reef fish. Together with the measured size and the location of fishing, this gives information for developing marine protected areas. Data is also collected from night fishing practiced by guests of the resorts.

Shark Watch

A diver or snorkel-based recording of shark sightings at the dive or snorkel site on a daily basis. Since the sharks were almost depleted from its water or overfished due to their fins, the tourists are now demanding to see sharks, so since 2009 they have introduced shark protection.

Under the climate change trust fund with World Bank funding a new project is being  implemented that will train and empower local community to monitor their coral reefs until September 2014.

A monitoring protocol is developing and a database is going to take shape for the entire country. With less than one per cent of the world’s oceans protected from exploitation and an estimation of that up to 80% of the world´s marine protected areas are only so called and not actively managed, it´s of urgent need to create properly managed and protected areas for the marine environment. All benefits of having marine protected areas are well known, such as conservation of the biodiversity and improvements of the local economy; however, it is so important for the future of the country, which is why a stakeholder approach is needed to monitor these areas and, if necessary, protect and preserve them.

Another issue to consider is how close they need to be, in order to promote connectivity between areas, and how many there should be, to provide a real protection for species. To enhance the resilience of the coral reef in the Maldives not only a reduction on pollution is needed, but also protection and managing existing marine areas properly, can work as an insurance for sustainability.

            ● Developing waste management systems on inhabited islands

–  The Maldives is facing one very big human impact and that is waste management. In the shadow of Thilafushi Island, which is the waste island close to Male the capital, the local islands are struggling with waste processing and associated water quality problems. The Maldivian islands are scattered over a very large area, so distance combined with an increase in population and consumption make the waste management issue very important to resolve.

– A pioneer project involving four northern atolls cooperating to manage the waste at just one island is set up to start working in 2014. This will join resort islands and local islands together, and act as a pioneer project to relieve the burden of Thilafushi.

–  By promoting this and taking care of waste closer to the islands where it originated, it is probable that less waste will be dumped in the ocean or buried in the sand or burned producing toxic gases.

–  So by doing this, not only will the local islands’ reefs get more resilient by alleviating the human impact, but also the resort island will have less waste washed up on their beaches. This is a good example of both locals and tourists benefitting and eventually the entire economy and the environment.

– Money from separate sources will also be implemented in several projects to teach segregation of waste at household level, and bins will be provided to store the waste separately until removal from the island.

–  Probably due to the fact that the islands have accumulated waste over time, a big clean up has to be organized to accomplish the objective of waste management.

The Maldives aims for a total protection of their waters and would like to proclaim the entire country a UNESCO biosphere reserve by 2017 and the country as a Marine Reserve by 2020. Let´s see how this amazingly beautiful country threatened by climate change and waste will manage with such big expectations.

Sylvia Jagerroos is a specialist in marine conservation and has spent the last two years working in the Maldives, a Country threatened by climate change and where the marine environment is directly linked to sustainable fisheries, renewable energy sources, tourism and a proper waste management system.

Shark Trust Asks Divers to help with Shark Sightings this Global Citizen Science Month

Published

on

Whether you are stuck for ideas of what to do with the kids or are off on the dive trip of your dreams. You can get involved in Citizen Science Month and help the Shark Trust by providing vital data about sharks are rays both close to home and further afield.

In addition to reporting the sharks and rays you see on your dives, the eggcases you find on the beach, the Shark Trust is looking for some specific data from divers who are asked to report any Oceanic Whitetip and Basking Sharks.

Oceanic Whitetip Sharks

The Shark Trust are looking specifically for Oceanic Whitetip Shark sightings over the coming weeks and months. So, if you are diving anywhere in the world, please report your sightings via the website or app.

Website: https://recording.sharktrust.org/

App: Search The Shark Trust in your app store

The Oceanic Whitetip. Known for their incredibly long dorsal and pectoral fins, this species was once the most abundant oceanic-pelagic species of shark on the planet.

Large and stocky, they are grey or brown above, and white below and famous for their huge rounded first dorsal fin and paddle-like pectoral fins. The fins also highly prized within the shark fin trade. Whilst they are mostly solitary, Oceanic Whitetips do occasionally hunt in groups.

An inquisitive species, they were easy prey for fisheries. Combined with their low reproductive rate, they were inevitably at high risk of population depletion. And declines of up to 99% have been reported in certain sea areas. They are listed as Critically Endangered on the IUCN Redlist (2019).

Conservation efforts to discourage further declines include listing on CITES Appendix II and CMS Appendix I. They’re also the only species prohibited from take by all the Tuna RFMOs (Regional Fisheries Management Organisations). However, these measures do not mean that Oceanic Whitetips are not still caught – whether targeted or as bycatch – in some parts of the world. With populations declining at such a high rate, effective implementation of management measures is essential to ensure that the species can recover.

If you are lucky enough to get an image of an Oceanic Whitetip and you record your sighting on the Shark Trust app or website YOU CAN WIN! All images submitted with sightings, that also give consent to use in conservation messaging, will be in with a chance to win an Oceanic Whitetip T-shirt and mug. The competition will run until the end of “Shark Month” in July – so keep those sightings (and images) coming in.

Basking Sharks

Basking Shark (Cetorhinus maximus) season is upon us, and the Shark Trust is asking everyone to keep an eye out for these majestic giants over the summer months. If you see any, you can record your sighting to the Basking Shark Sightings database.

Each year, these mighty fish return to British waters to feed on plankton. You may see one, (or a few if you’re really lucky) from around April-October. They can be seen feeding at the surface of the water, where they look like they’re basking in the sun. Thus, their name!

Sighting hotspots around the British Isles include southwest England, Isle of Man, north coast of Ireland, and western Scotland. The Sea of the Hebrides is the most prolific sightings area in Scotland, but they have been spotted all around the coast and have even ventured into some of the sea lochs. The Shark Trust has received thousands of sightings since the Basking Shark project began, but more data is needed to truly understand what is going on with population numbers and distribution. You can help by recording your sightings this summer.

Great Eggcase Hunt

The Shark Trust has an Easter Egg Hunt with a difference for you to try. Take part in the Great Eggcase Hunt and get involved with a big citizen science project that helps shark, ray and skate conservation. And it’s an enjoyable activity for all the family.

The Shark Trust also want snorkellers and divers to record their underwater eggcase findings. Underwater records help pinpoint exactly where sharks and skates are laying their eggs and can help link to beach records. Learning the depth and substrate that they lay on also helps better understand the species.
