Liverpool divers bring rubbish to the surface in Underwater Litterpick
Car number plates, a pair of sunglasses and a watch were just some of the items which divers from Liverpool-based club TS Neptune brought to the surface during an Underwater Litterpick in the city centre.
Members of the city’s TS Neptune Sub Aqua Club, which is linked to the sea cadets, staged the clean up in Liverpool’s Dukes Dock to celebrate the BSAC’s Diamond Jubilee and as part of the Club’s annual Underwater Litterpick campaign. Club members spent more than five hours clearing debris from the dock basin.
Keith Bayley-Hamilton, TS Neptune SAC Secretary and Assistant Diving Officer, said the day proved a big success with more than 100 separate items being cleared from the bottom of the dock.
He said: “Although the club is affiliated to the Sea Cadets it is open to anyone to join. We had two of our cadets join a dozen adult divers for the day and they thoroughly enjoyed the event.
“It is important to get across the importance of clearing up the environment and looking after what is an important underwater habitat for wildlife. The problem is people seem to think because rubbish is out of sight underwater it doesn’t matter.
“However, there is a huge amount of wildlife living in the docks, including crabs, dog fish and even jellyfish and we wanted to improve the environment in which they live.” Liam Williams, 12, a pupil of Alsop High School, Queen’s Drive, Walton, said he thoroughly enjoyed taking part in the Underwater Litterpick.
He said: “I found loads of bottles and old tin cans. It was a massive event which has been good for the environment. The visibility was quite good until the bottom got stirred up and I saw loads of stone fish and crabs.
“I started diving seven months ago with the sea cadets. I am an OC, ordinary cadet, and have qualified as a BSAC Ocean Diver. I want to carry on diving in the future, it’s brilliant.
“It’s especially good when we do stuff like clearing all the rubbish from the bottom of the docks. I think people who stopped to watch what we brought up were amazed at just how much trash there is in the docks.”
Keith Bayley-Hamilton says he was surprised not just by the volume of rubbish collected but by the variety of items found.
He said: “I think we all expected to find lots of bottles and tins but there were lots of other things too. Plastic is so harmful to wildlife yet there is so much of it.
“But we also found the odd old shoe, and a ladies watch although it certainly wasn’t an expensive one, more a type of fancy dress or piece of costume jewellery. And a pair of old sunglasses which was something of a strange find.
“It makes you wonder just how long some of these things have been lying in the dock and how they got there in the first place.”
The BSAC Underwater Litterpick 2013 runs until 31 October and clubs/individuals can still register to take part. Click here for details.
The Kingdom of the Netherlands will ask for increased protection for the Caribbean reef shark during next month’s Conference of Parties for the Cartagena Convention (COPs) on Aruba. Caribbean reef sharks play a critical role in maintaining a healthy reef ecosystem and building resilience within the oceans. This increased protection is critical for ensuring a sustainable future for this iconic species.
The Caribbean Sea is renowned for its crystal-clear waters, vibrant coral reefs, and a dazzling array of marine life. Among the charismatic inhabitants of this underwater paradise is the Caribbean Reef Shark (Carcharhinus perezii), a species that plays a crucial role in maintaining the health of coral reef ecosystems. In the Dutch Caribbean, these apex predators face mounting threats, but there is hope on the horizon. At the upcoming Conference of Parties for the Cartagena Convention (COPs), the Kingdom of the Netherlands will seek increased protection for these magnificent creatures by listing this species on Annex III of the SPAW Protocol. Annex III includes plant and animal species which require additional protection to ensure this species is able to adequately recover their populations in the Wider Caribbean Region.
Importance
Caribbean reef sharks thrive in warm, tropical waters of the Caribbean region, with a distribution range that stretches from Florida to Brazil. This species is one of the most encountered reef shark species throughout the whole Caribbean Sea. Growing up to 3m (9.8ft) in length, this shark is one of the largest apex predators in the reef ecosystem and is at the top of the marine food web, having only a few natural predators.
In addition to being of great economic value, as shark diving is a major draw for divers from around the world, this species is also critical for maintaining balance within the reef ecosystem. Their presence helps regulate the population of smaller prey species, which in turn, prevents overgrazing on seagrass beds and coral reefs and eliminates sick or weak fish from the population. This balance is essential for maintaining the health and diversity of the entire coral reef.
Threats
Despite their ecological and economic significance, Caribbean reef sharks in the Caribbean face numerous threats that have led to a population reduction estimated to be between 50–79% over the past 29 years. In the (Dutch) Caribbean this is mainly caused by:
Habitat Degradation: The degradation of coral reefs and seagrass beds due to climate change, pollution, and coastal development has a direct impact on the availability of prey for these sharks. Loss of habitat reduces their ability to find food and shelter.
Overfishing: Overfishing poses one of the most immediate threats to Caribbean reef sharks. They are often caught incidentally in commercial fisheries, where fishermen are targeting other species, or intentionally, where they are sought after for their fins, used in shark fin soup.
A Call for Increased Protection
There are different organizations and individuals working to protect sharks and their habitats in the Dutch Caribbean. A significant milestone was the establishment of protected areas such as the Yarari Marine Mammal and Shark Sanctuary between Bonaire, Saba and St. Eustatius. Another milestone was in 2019 when the Dutch government adopted an International Shark Strategy. The strategy sets out which protective and management actions for sharks and rays are to be taken by the government in all seas and oceans where the Netherlands has influence (including the Dutch Caribbean). Additional efforts are still needed to create more marine protected areas, enhance enforcement, reduce pollution in the ocean, and promote sustainable fishing practices. These species know no (political) boundaries and their protection requires broadscale conservation efforts within the Dutch Caribbean and beyond.
Conclusion
The Caribbean reef shark is a species of paramount importance to the (Dutch) Caribbean’s coral reefs. With the extra protection being requested during the next COPS meeting in Aruba, there is hope that this species will have a healthy future. By recognizing their ecological significance and the challenges they face, we can work together to ensure a brighter future for the Caribbean Reef Shark in the Dutch Caribbean and beyond.

The Reef-World Foundation, DiveAssure, and ZuBlu are launching a new collaboration to champion marine conservation while promoting sustainable diving practices. The symbiotic partnerships aim to increase awareness and implementation of environmental standards in the marine tourism industry through the Green Fins initiative, spearheaded by Reef-World in partnership with the UN Environment Programme.
Businesses have a unique opportunity to create a long-lasting impact through partnerships with conservation organisations. These partnerships show how tourism can go hand in hand with sustainability when businesses join forces with conservation organisations. By working together, these organisations and companies demonstrate their dedication towards sustainability and open doors to endless opportunities for growth and success in the tourism industry that benefit the people and the planet.
As the number of divers continues to grow and make a comeback post-pandemic, studies have shown that there’s a strong demand for sustainability education from dive tourists. This resulted in the partnership between Reef-World, DiveAssure and ZuBlu to promote sustainable diving practices through one of Green Fins tools, the Green Fins Diver e-Course. The course is designed for recreational divers to build on their existing scuba diving knowledge and provide them with the skills and confidence to conduct environmentally friendly diving trips. This, in return, empowers them to use their consumer power to demand more sustainable practices.
Chloe Harvey, Executive Director at The Reef-World Foundation, said: “We’re thrilled to be taking this step with these two wonderful companies. This is a truly symbiotic partnership, one that furthers the business priorities of DiveAssure and ZuBlu, as well as delivering on our conservation objectives. Reef-World has a long history of working with sustainability leaders in the diving industry, and with their support, we look forward to diving into a future where sustainability is at the heart of every dive adventure.”
What the partnerships entail for divers who have completed the Green Fins Diver e-Course:
- Get 20% off worldwide diving accident and dive-travel insurance from DiveAssure.
- Get 5% off scuba diving holidays booked with ZuBlu, a dive travel agency which has over 800 carefully chosen resort and liveaboard partners across 100 dive destinations worldwide.
- Reef-World to provide 10% off on Green Fins Diver e-Course for all DiveAssure and ZuBlu customers and members.
Besides offering a discount on their diving accident and travel plans, DiveAssure proudly supports top Green Fins Members across the globe with grants to fulfil their sustainability and conservation goals. Founded in 1999, DiveAssure has a goal of not only providing scuba divers with everything they might need in terms of safety and medical assistance, they are also committed to sustainability and the protection of our ocean. They champion responsible diving, endorse marine conservation, and continuously strive to minimise environmental footprints. Every quarter, DiveAssure evaluates initiatives proposed by Green Fins members — be it beach or reef cleanups, coral propagation, or setting up marine life nurseries. Dive centres keen to collaborate on such impactful endeavours are encouraged to reach out to info@greenfins.net for further details.
Tal Tamir, Business Development & Community Chief at DiveAssure, said: “We are thrilled about our new partnership with The Reef-World Foundation. We believe that sustainable diving is a key factor in preserving the beauty and biodiversity of our ocean. And that through education, we can raise awareness and drive positive change. The Green Fins courses empower divers and operators with knowledge about marine conservation, sustainable diving practices and the importance of protecting the ocean and its ecosystems — knowledge we encourage all our members to have. Green Fins Members are welcome to apply for funding for their blue-green initiatives, which are considered quarterly. Let’s do good together!”
With the “Explore the blue. Dive green.” tagline, ZuBlu celebrates sustainable businesses and encourages divers to be more environmentally conscious while on their adventures to contribute to a healthier ocean. Reef-World has proudly collaborated with ZuBlu since 2018, and this new partnership model represents a transformation in the impact they can have together. Their mission centres around improving the way travellers engage with the ocean. They believe every dive starts at home, and every decision made in planning a holiday can make a difference to the marine environment. With access to information on the sustainable practices implemented by their featured resort and liveaboard partners, they can ensure their customers find sustainable operators to book their ocean adventures with.
Adam Broadbent, co-founder and CEO at ZuBlu, said: “We are delighted to be deepening our collaboration with The Reef-World Foundation to further encourage more conscious divers. At ZuBlu, we want to empower our guests to be a force for good on their scuba diving adventures. And we are delighted to be rewarding Green Fins Divers with a 5% discount to acknowledge their commitment to the ocean.”
