The Lionfish Kings of Grand Cayman’s East End

Published

on

“Lionfish are beautiful, resilient and strong – a cool fish – but they are deadly to our reefs and if we don’t stop them something bad is going to happen,” says Matt Russell, a divemaster/instructor at Ocean Frontiers who has watched the invasion with deep concern for the marine environment. Russell is a dedicated, educated and skilled warrior in the fight against the predatory Lionfish, consistently culling large numbers on dives – a record 56 fish during a 2-tank dive. He’s also a member of the very exclusive “30 Club” whose members have removed 30 or more Lionfish on a single dive. Matt also teaches customers how to safely and humanely remove the invasive species from the reefs.

Cayman 2“The hunt was wickedly fun at first, but now I feel an obligation to get as many people involved as I can,” he says. Matt and his co-workers follow the lead set by their boss Steve Broadbelt (also a member of the 30 Club) who is out there hunting and spearing as many Lionfish as he can on company culls.  “We’re pretty competitive! Steve ‘gets it’ and understands that we need to keep the pressure on.”

This attitude and the resulting teamwork is why Ocean Frontiers is winning the local battle against invasive Lionfish prowling the reefs at East End, if not the broader war against the predator.  Broadbelt and his team aggressively press on, culling as many predators as they can, and encouraging locals and customers to get involved in the fight. In March they crossed an important thresh hold – they have removed 10,000 Lionfish from East End reefs since they began culling three years ago.

Also this month their best customer for the fish, Chef Ron Hargrave, who operates Tukka at East End and Eagle Ray’s Dive Bar & Grill at Compass Point Resort, calculates that he has purchased 6000 pounds of Lionfish at a cost of $25,000. This partnership between Broadbelt and Hargrave is an example of how the community can help fight the Lionfish invasion, and it exemplifies the hope behind the mantra being repeated across the Caribbean: to beat them eat them.

Culling invasive Lionfish is a day in, day out challenge, and while eradicating them completely from Cayman’s reefs is unlikely, Ocean Frontiers is hoping to keep the predator population manageable at East End dive sites. Once a week, Ocean Frontiers runs a one-tank afternoon cull, and customers are asked to help by being Lionfish spotters for trained cullers. This helps keep the Lionfish population low on regular dive sites, but a more aggressive approach is needed for other areas of the reef not regularly dived. Ocean Frontiers also offers an all-day 3-tank cull once a month for Cayman residents who are licensed to use spears and have their own DoE approved spears. The dive operation also offers a culling class, taught by Matt Russell, for customers interested in being trained and licensed to spear Lionfish.

Cayman 3“These trips target the hard to reach areas that are too far to get to on a typical half day trip,” says Broadbelt.  “We’ve also developed what we call ‘parachute drop culling’ where we split the residents into three teams and drop them off along the reef sequentially the estimated distance apart that they are expected to cover. This enables us to cull over 1 mile of linear reef at a time and has resulted in many top scores. This method can only be used in the right conditions with advanced divers that we are comfortable with… I would class it as an extreme dive, but worth the results.”

The numbers tell the story: to date Ocean Frontiers has culled a total of 10,202 Lionfish; 1008 divers have participated in culling dives; the most fish ever culled in one day is 320; the most culled by a single diver in one dive is 39; the longest Lionfish caught is approximately 13 inches measured from nose to base of tail; the smallest is about 2 inches. Everything is carefully documented and the results are reported to the Department of Environment where a Lionfish database is kept.

Chef Ron Hargrave takes all the Lionfish being harvested at East End, no matter the size, and adds them to his menu. He says most of their customers are aware of the issue and support the cause by ordering at least one Lionfish dish – among the most popular are the famous Lionfish Tacos served at Eagle Ray’s Dive Bar & Grill.

Cayman 4“Customers love it! And why not… Its delicate, flakey, white meat is very mild and extremely tasty,” he says, adding that demand is going up all the time.

“The Lionfish tacos at Eagle Ray’s are probably the best I’ve ever had and they are on the menu 100% of the time,” says Matt Russell who often recommends them. “I’ll ask customers ‘did you try those fish tacos? I caught them!’”

Steve Broadbelt says licensed local cullers joined the fight once they understood the threat posed by the Lionfish, and they continue to be involved.

“Divers do not like harming or killing (culling) marine life, but we have to be smarter than our emotions and understand the damage the Lionfish are doing and the importance of our environmental work,” he says. “We employ some of our own techniques to make sure the Lionfish are terminated as quickly and humanely as possible. There is no reason to make them suffer – they are just not welcome here.”

“You have to take care of the things you love and there are few things I love more than Cayman’s reef life,” says local customer Mark Rovner, a licensed spearer. “At first I was apprehensive about killing fish, but once you understand the horrific damage these invasives can do, you realize there’s no choice. And if not me, who?

Broadbelt says getting Ocean Frontiers customers involved in culling is easy when they become aware of the threat Lionfish pose and sometimes a little competition keeps the hunt interesting.

Cayman 5“We make the culling trips fun and competitive by encouraging a little rivalry and team spirit,” he says. “Most divers don’t need motivation. They care about the environment and there is always this desire to do a good thing and help with the problem. Some of them just love it and can’t get enough.”

Is regular culling it working? Broadbelt says the data they’ve collected and submitted to the Department of Environment indicates that Lionfish counts and sizes are being reduced. Customers are also seeing fewer of them during dives on return trips.

“When I started, the lionfish populated almost every dive site. Now it is a surprise to see a lionfish,” agrees regular customer John Sharp who has participated in culling dives.

“Yes culling is making a difference, but it is like a leaking boat,” says Steve Broadbelt. “Every time we bail out some water… more just keeps coming back in. We can keep bailing and bailing, but we have to find a better long term solution.”

Get ready for the Marine Conservation Society’s annual Great British Beach Clean this month

Published

on

Great British Beach Clean

The programme is one of the largest marine citizen science activities of its kind in the UK. Volunteers taking part will not only be clearing our beaches of litter, but help the Marine Conservation Society, the UK’s leading ocean membership charity, to gather vital data to create change for cleaner and healthier seas.

This year’s Great British Beach Clean is being sponsored by Ireland’s leading soup brand, Cully & Sully Soup, whose support is helping to raise awareness of marine litter and protect UK beaches from pollution.

To sign up for a beach clean, or organise your own, simply visit the charity’s website.

Great British Beach Clean

Key stats and facts

  • At last year’s Great British Beach Clean, 5,416 volunteers conducted 428 beach cleans over 10 days, surveying 64,139 metres of coastline. A total of 129,391 pieces of litter were collected, filling 1,426 bags and weighing 7,476 kg.
  • The Marine Conservation Society has recorded an average drop of 80% in carrier bags found on UK beaches since charges were introduced, showing that policies to reduce plastic work.
  • Data collected during the Great British Beach Clean contributes toward the charity’s annual State of our Beaches report. Last year’s report recorded a 14% increase in drinks-related litter.
  • The report also showed that nine out of 10 beach litter items found on beaches by Marine Conservation Society volunteers last year were made from plastic.
  • Sewage plays a large part in the pollution problem. In 2023, over 29,500 sewage-related items, including more than 21,000 wet wipes, were recorded across the UK and Channel Islands, with sewage-related items present on 72% of surveyed beaches.
  • Data from the Marine Conservation Society’s Great British Beach Clean contributes to a global database, International Coastal Cleanup.

Great British Beach Clean

Key messages:

  • Data collected by volunteers during the Great British Beach Clean shows the positive result of policies like carrier bag charges, and how they work to reduce litter on our beaches.
  • Plastic still remains the most common form of beach pollution – highlighting the urgent need for further action to tackle the single-use plastic problem such as charges, bans and deposit return schemes.
  • The Marine Conservation Society is calling for governments across the UK implement world-class deposit return schemes for drinks containers including glass, plastic, and cans, without any further delay. Currently the proposed scheme is set to start in October 2027, but with Wales being the only country to include glass.
  • The charity hopes that the recent bans on single-use plastics, such as cutlery, will lead to a noticeable reduction in the amount of single-use plastic cutlery polluting our beaches, much like the positive impact of the carrier bag charge.
  • Sewage-related pollution, such as period products and wet wipes, are still prevalent on our beaches. Governments of the UK must turn the tide on pollution and end untreated sewage damaging our marine environment.
  • You can support the charity by helping to clean up the UK’s beaches and collecting valuable data that supports efforts to address sewage pollution effectively.

ON THE DEPOSIT RETURN SCHEME:

Lizzie Price, Beachwatch Manager at the Marine Conservation Society: “It’s fantastic to see real-world evidence of the effectiveness of policies such as carrier bag charges in tackling pollution from single-use plastics. There’s no denying that these measures have helped to reduce litter on our beaches. However, we cannot afford to become complacent.

“Drinks-related litter, such as bottles and cans, were found on 97% of UK beaches surveyed last year. We need wider policies such as charges, bans, or deposits on more single-use items where possible, including the proposed deposit return schemes for plastic bottles, cans, and glass. We must keep moving towards a society that repairs, reuses, and recycles.”

ON SEWAGE POLLUTION:

Rachel Wyatt, the Marine Conservation Society’s Water Quality Policy & Advocacy Manager:

“Our seas cannot sustain the deluge of sewage that is being dumped into our waterways on a weekly basis. Our beach clean volunteers find thousands of sewage-related litter items washed up on the beaches every year, but it’s not just physical pollution that is harmful to us and marine life. Raw sewage contains a cocktail of bacteria, viruses, harmful chemicals, and microplastics which is a disaster for our ocean. Governments of the UK must turn the tide on pollution and end untreated sewage damaging our marine environment, so that we can all enjoy sewage-free seas.”

ON VOLUNTEERING:

Clare Trotman, Beachwatch Officer at the Marine Conservation Society, said: “The work we do at the Marine Conservation Society simply wouldn’t be possible without the dedication of our volunteers, who help gather crucial beach litter data. This information is invaluable in shaping scientific understanding and driving the changes needed to protect our precious marine environment.

“With beach cleans taking place all over the UK and Channel Islands, there are countless opportunities to get involved and support us this year. And if you can’t make it to the beach, you can still contribute by organising a local litter pick and survey in your area.”

Cully Allen from Great British Beach Clean sponsor, Cully & Sully Soup, said: “We are excited to be part of the UK’s biggest beach clean initiative for a third year. As a B Corp, doing good is at the core of what we do. We are always striving to do better internally as a business, but we really enjoy when we get to encourage and join our customers in doing good. We are looking forward to getting stuck into the beach cleans again this year, serving up our soup to the SOUPer volunteers and taking direct action on marine litter.”

Reef-World launch new toolkit in response to the current global coral bleaching event

Published

The Reef-World Foundation – international coordinator of the UN Environment Programme’s Green Fins initiative – has launched a new coral bleaching toolkit in response to the 4th global coral bleaching event confirmed by the National Oceanic & Atmospheric Administration (NOAA) and International Coral Reef Initiative (ICRI) in April 2024.

The Green Fins Global Coral Bleaching Response Toolkit provides guidance to the marine tourism industry on how they can help manage and monitor the impacts of coral bleaching and get involved in recovery efforts. It features information about coral bleaching, including the causes, impacts and response strategies. The toolkit is compiled from a variety of readily available resources from multiple organizations and initiatives, such as ICRI, Coral Reef Alliance, Reef Check and NOAA, along with Green Fins materials, to ensure it is accessible to everyone. These resources cover methods for reducing local impacts, monitoring the reefs and engaging tourists and local communities.

The El Niño phenomenon has been present since February 2023, which has led to persistently warmer temperatures being experienced around the world and has affected the sea surface temperatures. Coral bleaching has been recorded in all ocean regions ever since. While this event is widespread and serious, there is still hope as bleached corals are not dead corals. Corals can survive bleaching events and thrive if they are given the time to adapt to the changing climate.

“Coral reefs are under a huge amount of stress every day and that reduces their chance of recovery from bleaching events,” said Chloe Harvey, Executive Director at The Reef-World Foundation. “However, this time around the scientists have been watching the data closely, so we’re prepared. We understand what it means and we know what we need to do to respond to it. This global event calls for global action to protect these vital ecosystems for generations to come.”

By equipping the industry with the necessary knowledge and tools, Reef-World hopes to empower these key stakeholders to play a crucial role in preserving the health and resilience of our precious coral reef ecosystems. Reef-World believes that with the right resources, the marine tourism industry can be a driving force in the fight against coral bleaching and contribute significantly to the long-term sustainability of marine environments.

With this momentum, other key players in the industry, such as PADI AWARE Foundation and NOAA, have gotten on board the campaign for more citizen scientists to help out in monitoring coral bleaching. With the toolkit available to all, The Reef-World Foundation is looking forward to more collaborative actions in the industry.
