Micro plastics ‘pose toxic threat to marine biodiversity’

Tiny particles of waste plastic that are ingested by shoreline “eco-engineer” worms may be negatively affecting biodiversity, a study says.
So-called microplastics may be able to transfer toxic pollutants and chemicals into the guts of lugworms, reducing the animals’ functions.
An estimated 150 million tonnes vanishes from the global waste-stream each year.
The findings have been published in the academic journal Current Biology.
“We are losing a large volume of plastic and we know it is going into the environment and the assumption being made by policymakers is that this material is non-hazardous, it has got the same ranking as scraps of food,” explained co-author Mark Browne, an ecologist from the US-based National Center for Ecological Analysis and Synthesis.
“The research we have done really challenges that,” Dr Browne added, referring to the findings of lab work carried out by colleagues at Plymouth University, UK, led by co-author Prof Richard Thompson.
“Our findings show that the plastic itself can be a problem and can affect organisms.
“Also, when particles of plastic go into the environment what you find is that they accumulate large quantities of pollutants that are banned. So you have these particles themselves but also a load of nasty chemicals.”
The team found that the tiny bits of plastic, which measure 1mm or smaller, transferred pollutants and additive chemicals – such as flame-retardants – into the guts of lugworms (Arenicola marina).
This process results in the chemical reaching the creatures’ tissue, causing a range of biological effects such as thermal stress and the inability to consume as much sediment.
Dr Browne explained that this had consequences for the surrounding ecosystem.
“If the animals are not able to eat as much then there is a change in the function of the organisms and there is an impact on the semblance of the species found in an area,” he said.
He added that the worms had earned the nickname “eco-engineers” as a result of their ability to eat organic matter from the sediment and prevent the build-up of silt.
“Through that process, it produces burrows and changes the whole assemblage of animals that live around it,” Dr Browne observed.
“This is quite considerable because if you look at the total biomass of a shoreline, about 32% can be made up from these organisms.”
He told BBC News that it was the first study of its kind to highlight the toxic risk posed by microplastics to marine organisms.
“For about 40 or 50 yeara, we have been finding very large concentrations of chemicals in animals. Then they started to find animals with larger concentrations of pollutants and plastics, so researchers began to establish this correlation.
“But no-one had actually shown whether chemicals could transfer from plastic when they are eaten by animals and accumulate in their bodies and reduce important functions that maintain their health.”

Shaping Tomorrow’s Shores: The Future of Coastal Habitat Restoration

A new partnership between World Wide Fund for Nature – Netherlands (WWF-NL) , the Dutch Caribbean Nature Alliance (DCNA) and Coastal Dynamics will spearhead an initiative to define future conservation and restoration projects within Dutch Caribbean coastal habitats. Centered around mangroves and seagrass beds, this ambitious feasibility study aims to craft a portfolio of forward-looking projects. The objective is to fortify these areas against escalating threats like climate change, pollution, and unsustainable coastal development, ensuring their sustained health and resilience.
The Dutch Caribbean is home to unique island ecosystems facing challenges from overdevelopment, climate change, and other environmental pressures. Coastal ecosystems represent critically important areas, particularly in regards to their biodiversity, climate resilience, and cultural heritage. The proposed feasibility study seeks to bridge gaps in expertise, resources, and collaboration across all six of the Dutch Caribbean islands (Aruba, Curacao, Bonaire, Saba, St. Maarten and St. Eustatius).
Goals
The primary goal of the project is to conduct an in-depth feasibility study under the DCNA’s Conservation and Restoration of Key Habitats Program. Key components of the study include assessing the current status of mangroves and seagrass beds, stakeholder engagement, and conducting an overall resource assessment.
Nature-Based Solutions
The study will focus on coastal area restoration, specifically targeting mangroves and seagrass beds in collaboration with Dutch Caribbean Park Organizations. The aim is to develop a nature-inclusive approach with nature-based solutions to enhance resilience and sustainability. Overall, this project has two main objectives:
- Feasibility Study: Assess the viability of conservation efforts, including technical, financial, and human resource requirements.
- Knowledge Sharing & Capacity Building: Present findings, address knowledge gaps, and build capacity among Park Organizations for effective restoration initiatives.
Forward Planning
The feasibility study’s success is crucial for creating a comprehensive understanding of coastal habitat conditions, fostering collaboration, and laying the groundwork for future restoration programs. By unifying efforts, the study aims to enhance communication, knowledge sharing, and resource utilization across all six islands.

Hunting Lionfish Safely and Responsibly in Curaçao

Curaçao, a picturesque island in the southern Caribbean, is not only renowned for its stunning beaches and vibrant culture but also for its commitment to preserving its marine ecosystems. One of the key threats to these delicate ecosystems is the invasive lionfish. To combat this menace, responsible hunting practices are crucial.
In this comprehensive guide, we will explore how to hunt lionfish safely and responsibly in Curaçao, including the use of pole spears (the only legal method in Curaçao). We will provide you with the top 10 safe hunting practices, including the use of a Zookeeper. We will also address what to do if you are stung by a lionfish and emphasize the importance of consulting with local experts before embarking on your lionfish hunting adventure.
Why Safe and Responsible Lionfish Hunting is Important
Lionfish (Pterois spp.) are native to the Indo-Pacific region but have become invasive predators in the Caribbean, including the waters surrounding Curaçao. Their voracious appetite for native fish species and rapid reproduction rates poses a severe threat to the delicate balance of marine ecosystems in the region. The introduction of lionfish has led to a decline in native fish populations and the degradation of coral reefs.
To counteract the lionfish invasion, responsible hunting practices are essential. Hunting lionfish can help control their population and protect the native marine life of Curaçao’s waters. However, it is imperative to follow safe and responsible hunting techniques to minimize the impact on the environment and ensure the safety of both divers and the marine ecosystem.
Understanding the Pole Spear
In Curaçao, the only legal method for hunting lionfish is using a pole spear. It’s important to note that a pole spear is distinct from other spearfishing equipment, such as a Hawaiian sling or a spear gun with a trigger mechanism. The use of Hawaiian slings or spear guns with triggers is illegal in Curaçao for lionfish hunting due to safety and conservation concerns.
A pole spear consists of a long, slender pole with a pointed tip, often made of stainless steel or fiberglass, designed for precision and accuracy. Unlike a trigger-based spear gun, a pole spear requires the diver to manually draw back on a rubber band then release towards the target, providing a more controlled and selective approach to hunting.
How to Hunt Lionfish Using a Pole Spear Responsibly
When using a pole spear to hunt lionfish, it’s crucial to do so responsibly to ensure the safety of both the diver and the marine environment. Here are some essential guidelines on how to hunt lionfish using a pole spear responsibly:
- Safety First: Always prioritize safety when diving and hunting. Ensure you have the necessary training and experience for hunting lionfish. Consider the Lionfish Scuba Dive Experience offered by Ocean Encounters. This opportunity allows participants to learn under the expert guidance of local scuba diving professionals.
- Check Regulations: Familiarize yourself with local regulations and restrictions related to lionfish hunting in Curaçao. Respect no-take zones and marine protected areas.
- Target Only Lionfish: Use your pole spear exclusively for lionfish hunting. Do not attempt to spear any other species, as this can harm the fragile ecosystem.
- Aim for Precision: Approach your target lionfish carefully and aim for a precise shot to minimize the risk of injuring other marine life or damaging the coral reef.
- Use a Zookeeper: A Zookeeper is a specialized container designed to safely store and transport lionfish after capture. It prevents the lionfish’s venomous spines from causing harm and keeps them secure during the dive.
- Respect Lionfish Anatomy: Target the head of the lionfish and stay away from its venomous spines. Aim for a clean and humane kill to minimize suffering.
- Avoid Overhunting: Do not overhunt lionfish in a single dive. Limit the number of lionfish you catch to what you can safely handle and process.
- Practice Good Buoyancy: Maintain excellent buoyancy control to avoid inadvertently damaging the reef or stirring up sediment, which can harm marine life.
- Dispose Responsibly: Once you’ve caught lionfish, carefully place them in your Zookeeper. Do not release them back into the water, as they are invasive and harmful to the ecosystem.
- Report Your Catch: If applicable, report your lionfish catch to local authorities or organizations involved in lionfish management to contribute to data collection efforts.
In the Unlikely Event of a Lionfish Sting
While lionfish stings are rare, it’s essential to know how to respond if you or someone you are diving with is stung. Lionfish have venomous spines that can cause pain, swelling, and even more severe reactions in some cases. Here’s how to respond to a lionfish sting:
- Signal for Help: Notify your diving buddy or group immediately if you are stung.
- Remove Spines: If the spines are still embedded in the skin, carefully remove them with tweezers or a clean, sterile tool. Be cautious not to break the spines, as this can release more venom.
- Clean the Wound: Rinse the affected area with warm water to help alleviate pain and reduce the risk of infection.
- Pain Management: Over-the-counter pain relievers like ibuprofen or acetaminophen can help with pain and swelling. However, if you experience severe symptoms, seek medical attention promptly.
- Seek Medical Help: If the pain and swelling worsen or if you have an allergic reaction to the venom, seek medical assistance immediately.
Consult Local Lionfish Experts
Before embarking on a lionfish hunting adventure in Curaçao, it’s crucial to consult with local and responsible dive shops or organizations dedicated to lionfish management, such as Lionfish Caribbean.
These experts can provide valuable insights, tips, and up-to-date information on how to hunt lionfish safely and responsibly, hunting locations, safety measures, and environmental conservation efforts.
Start Planning your Next Caribbean Adventure
Knowing how to hunt lionfish safely and responsibly in Curaçao is not just an exciting underwater activity but also a crucial step in protecting the island’s marine ecosystems. By using a pole spear and adhering to the top 10 safe hunting practices, including the use of a Zookeeper, you can contribute to the control of the invasive lionfish population while preserving the delicate balance of Curaçao’s underwater world.
Remember that safety should always be your top priority when diving and hunting lionfish. In the unlikely event of a lionfish sting, knowing how to respond can make all the difference. By consulting with local experts and following ethical and legal guidelines, you can enjoy a rewarding and responsible lionfish hunting experience while safeguarding the beauty of Curaçao’s marine environment for generations to come.
