Basking Sharks Injured by Marine Debris

Published

on

After spotting a basking shark this summer with rope around its nose we were rightly upset about the distress that was being caused to the shark. White abrasions can be seen where the rope has been cutting in and being in close proximity to the eye, must be damaging.

We did not see the shark again, so unfortunately couldn’t help it even after gaining the necessary means in which to do so. After a request to use the image of the shark to show school kids, highlighting the problem of marine debris, I did some searching on the net to see if any sharks had been seen before.

We found out that another shark with plastic on its nose was seen in 2012 by Craig Whalley round the Isle of Man (see his picture below). We got in touch with Craig (a kayaker from the IoM) and Jackie Hall from the Manx Basking Shark Watch. They had actually seen their shark this summer (2013) too, two years in a row. They named the shark Ringo for obvious reasons, putting an upbeat side to the shark’s predicament.

Initially we thought it was good news that the basking shark had been seen and that the shark was surviving under the circumstances. However after checking videos and pictures (looking for the sharks ‘bits’) it seems that we had spotted a female but the IoM shark was male.

The debris on our shark does appear to look like rope and the IoM like the plastic wrapping that goes round cardboard boxes. Jackie also advised that Colin Speedie, a Basking Shark researcher, saw one in 2001 fouled by plastic wrapping off Cornwall. So it’s very distressing to hear that three of our gentle ocean giants have been affected by our waste in such a way.

What you also must remember that a sharks nose is a highly sensitive part of its body, an area where the sharks electro-senses are concentrated. There is no question that this fouling will have an effect on the shark. Imagine what it would be like to have something on a sensitive part of your body but not have the means to remove it! The way I think about it, is having a splinter of wood stuck under your fingernail but not being able to get it out. Painful and extremely irritating.

From seeing these amazing sharks in this state, the lesson for us is to make sure you cut any strapping up before you dispose of it. If you are walking along the beach, please pick it up.  Make sure that you dispose of all waste responsibly and along with the bigger issues of marine debris, try to reduce the amount of plastic that you use!

If we ever see this shark again, we’ll be geared up to help it. Please share this message with everyone so the message hits home about our how rubbish is effecting our ocean giants. With lots of messages of around the world about the issue of marine debris, here’s a real story from your own doorstep – it’s up to you to do something about it!

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.

Hunting Lionfish Safely and Responsibly in Curaçao

Published

on

lionfish

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:

  1. 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.
  2. Check Regulations: Familiarize yourself with local regulations and restrictions related to lionfish hunting in Curaçao. Respect no-take zones and marine protected areas.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. Practice Good Buoyancy: Maintain excellent buoyancy control to avoid inadvertently damaging the reef or stirring up sediment, which can harm marine life.
  9. 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.
  10. 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:

  1. Signal for Help: Notify your diving buddy or group immediately if you are stung.
  2. 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.
  3. Clean the Wound: Rinse the affected area with warm water to help alleviate pain and reduce the risk of infection.
  4. 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.
  5. 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.
