Lethal Lionfish

Published

on

One of the more dangerous fish living in our waters, the Lionfish, and sadly not due to being a combination of a south African lion and a small fish, it received its name from its long, flowing colourful dorsal fins atop its body. Although they may look beautiful, these dorsal fins are actual the reason the lionfish is so lethal to some.

This lion (not the four-legged kind) is native to the Indo-pacific region, living from 1 to 300 feet below the surface and, of course, like its land counterpart, the lionfish enjoys the warmth, despite this, they are often known to be an invasive species in the Atlantic Ocean. Growing up to, at largest, 18 inches a year, and laying up to 2 million eggs a year, this impressive species bodes quite well in life, with a very broad range of prey to feed off, Lionfish are generalists and will feed off pretty much anything they can, from small fish to crustaceans and molluscs, they can expand their stomachs up to thirty times its normal size (as most of us can around Christmas, I’m sure).

They are nocturnal, so do most of their hunting at night, using those overly large, magnificent looking fins and their bilateral swim bladder muscles to corner their prey, intimidate it and then devour it. All these spines and fins that they carry around to intimidate prey are, sadly, more than just intimidating, they’re quite venomous too, with the interesting ability to poison other marine creatures. Luckily, they are not deadly to humans, but they can cause severe pain, nausea and even paralysis, something I’d strongly recommend you avoiding (because what else am I here for if not to state the obvious!).

They have several venomous spines and non-venomous fins, on the venomous side there’s the Anterior dorsal fin, the anal spines, the pelvic fin and the pectoral fin. As for non-venomous: the posterior dorsal fin, caudal fin and anal fin. The spines they carry not only act as a hunting device but also as a defence mechanism, protecting the lionfish from its own predators.

Although the lionfish may sound completely horrendous in most cases, especially to other marine life, they are quite slow moving, which means they aren’t too much of a threat in comparison to some things below the surface, and usually they’re very uninterested in humans, as we probably don’t taste as good as crab. Being very beautiful creatures, though, means sadly they’re quite popular in the aquarium trade, which, can at times be unethical and therefore harmful; luckily they are not endangered, but pollution does put them at risk.

Saba’s Plan for a Coral Comeback

Published

on

Saba

Saba has an exciting new initiative to restore its coral reefs. This new project, running from 2024 to 2026, will focus on reviving key species in the island’s underwater ecosystems. With a collaborative team from the Saba Conservation Foundation (SCF) and Van Hall Larenstein (VHL) University of Applied Sciences, the project aims to restore both corals as well as sea urchins.

This initiative is centered around coral restoration, specifically reviving two essential coral species—staghorn coral (Acropora cervicornis) and elkhorn coral (Acropora palmata).  By mapping parent colonies and using a technique known as coral gardening, SCF will create and maintain coral nurseries. These corals will eventually be outplanted at key reef sites around Saba to not only expand the number of coral colonies, but also provide essential fish habitat. The project focusses on installing coral nurseries, training staff with the newest techniques and starting with the restoration of key reef sites.

Reef Cleaners to the Rescue

It’s not just corals getting a makeover—this project also shines a spotlight on the essential role of grazers, particularly sea urchins. VHL is leading the charge on cultivating and restocking two key sea urchin species, West Indian sea egg (Tripneustes) and long-spined sea urchin (Diadema), known for their ability to keep algae in check. By removing algae, which are important competitors of corals, they help the coral to thrive. By restoring these “reef cleaners,” Saba’s project will give corals the breathing room they need to grow, setting the stage for a healthier, more balanced marine ecosystem.

From Tiny Urchins to Big Goals

The project will be funded as part of the Dutch Government’s Nature and Environment Policy Plan (NEPP) 2020-2030 for the Caribbean Netherlands, a comprehensive initiative aimed at conserving and restoring the unique natural environments of the Dutch Caribbean islands, including Saba, St. Eustatius, and Bonaire. This project is aiming for big milestones:  build and maintaining coral nurseries, the expansion of urchin cultivation facilities, and the creation of a dedicated research center. By 2026, the project hopes to ramp up coral and grazer restoration, with the ultimate goal of extending these efforts across the Dutch Caribbean. By linking local initiatives to broader regional goals, Saba’s restoration project promises to leave a lasting impact on both the environment and the community.

Reef-World marks two decades of marine conservation: strengthening impact amid coral reef threats

Published

Empowering ocean stakeholders to tackle future challenges and ensure the survival of coral reefs and humanity

2024 marks the 20th Anniversary of The Reef-World Foundation’s tireless efforts for global coral reef conservation. The UK charity is the international coordinator of the UN Environment Programme’s Green Fins initiative, known as the leading voice in sustainable marine tourism. Today, Reef-World released its 2023-2024 Impact Report outlining a year of substantive growth and impact in its marine conservation programmes. 

Impact Report Highlights:

  • Impressive improvements in environmental behaviours to protect coral reefs by the marine tourism industry as the global participation of Green Fins increases.
  • Continued capacity building for government and NGO staff to effectively manage marine tourism activities in Asia, Caribbean and Red Sea regions. 
  • For the first time in Green Fins’ 20-year history, tourism operators have achieved ‘Best Environmental Performer’ status by demonstrating the lowest possible environmental impact in their environmental assessments. In 2024, three dive operators achieved this challenging milestone. 
  • Significant increases in global participation of Reef-World’s innovative digital conservation tools.
  • 138 Green Fins dive operator members achieved the strict threshold for PADI Eco Center recognition.
  • Developed four new educational materials and translated two into 16 languages to support the marine tourism industry in achieving sustainability targets.
  • Establishing a new Reef-World Development strategy and recruiting new roles – Development and Programmes Managers. 
  • Reef-World’s board welcomes new Chair and Trustees strengthening organisational leadership. 

Reef-World started as a one-person mission to inspire and empower communities to act in conserving and sustainably developing coral reefs and related ecosystems. Today, the team of 12 continues to meet this mission by inspiring and empowering the global marine tourism community to be exemplary sustainability leaders by using the Green Fins guidelines and tools to simultaneously use and protect the world’s precious reefs. 

In April 2024, the fourth global coral reef bleaching event was confirmed. Reef-World’s work has never been more urgent as the marine environment, and the benefits they provide humanity, continue to be eroded by global threats. The reduction of local threats, like those from the marine tourism industry, is an essential step to ensuring a future where coral reefs survive and continue to support the millions of people who depend on their ecosystem benefits. Reef-World’s work buys time for coral reefs and related ecosystems to be resilient to the impacts of global threats. 

 

“Right now our corals are facing the greatest fight of their existence as the terrifying predictions of the steps towards their complete extinction are starting to come true. But all is not lost, reefs are resilient and they have existed on this planet for millions of years. We must take action now, to buy time for reefs by reducing threats facing them and allowing them to react and adjust to the changing environment they need to survive in.” – Chloe Harvey, Executive Director

Looking Forwards: 

Like coral reefs, the Reef-World team needs to be resilient in the face of the complex challenges of the conservation sector. Reef-World has invested significantly in developing a Culture of Care to ensure the well-being of its team on a daily basis, continuing to be an exemplary employer to enable its team to best achieve the mission for coral reef conservation.

With the foundations of a Culture of Care and organisational development laid, Reef-World is emerging from the end of a natural organisation life cycle, that brings the challenges of growth and scale, stronger than ever. With a new strategy in place to generate much needed resources, Reef-World is excited for the opportunities to leap forward, continue to scale our impact and lean into new innovations and untapped opportunities for marine conservation. 

We continually strive to become a forward-thinking organisation that delivers on our goals and commitments to our stakeholders with fresh approaches and not being afraid of steering away from a “normal approach.” This approach is not only applied to our programmes of work but also internally and carries over to our Culture of Care for our team.” — JJ Harvey, Operations Director
