Poisonous fish in the sea: first aid on a yacht

Good news for boaters and cruisers

There are virtually no poisonous fish on most popular yacht cruising routes. The chance of encountering dangerous marine life is quite low, so unnecessary alarm is inappropriate.

Besides, even deadly sharks are not so scary for humansas it seems at first glance. However, the golden rule of sailors is that danger should not be feared, but one must be prepared for it.

The same applies to poisonous fish. With the right level of preparation and calm, even such a meeting will be just one of many experiences on an exciting cruise.

Basic facts about poisonous sea fish

Studying all the features of poisonous fish is difficult due to their diversity, but most dangerous fish have distinctive features that allow them to be recognized:

• They often have an inconspicuous coloration, allowing them to blend in with their surroundings;
• Or, conversely, abnormally bright body coloring can also serve as a warning of potential danger;
• Poisonous fish prefer warm water and are usually found in tropical and subtropical waters;
• They have spines or characteristic growths on the body, often on the head or sides;
• Many venomous species are shy and will swim away or hide when humans approach unless you step on them underwater.

Although venomous fish can be intimidating in appearance, most of them use venom only as a defense and not as an attack.

There is no need to be afraid of meeting these fish, but before going on a cruise it is worth studying their habitat and comparing it with your route. This preparation will help you be prepared and avoid unpleasant surprises while traveling by sea.

First aid for contact with poisonous fish

Pay attention to the symptoms: often a person first steps on the fish and only then feels a burning pain in the limb. After contact with poisonous fish, the victim may experience nausea, vomiting and increased body temperature - this is the result of the action of toxins.

If there are no doctors nearby, it is important to provide first aid yourself. Begin by immediately rinsing the wound to remove sand, dirt, and any remaining poison. If fragments of the thorn are visible, they should be carefully removed. If the spines are too small or difficult to remove, seek medical attention immediately.

Then immerse the affected limb in hot water (approximately 45°C) until the pain disappears, which will help neutralize any remaining venom. To relieve pain and reduce fever, you can take non-steroidal anti-inflammatory drugs such as aspirin or ibuprofen.

Even if the pain goes away quickly, you need to visit a doctor in the nearest port or marina. Don't hesitate to ask the Coast Guard for help if you're in a remote area; Providing assistance in such situations is their direct responsibility. Consult a doctor as soon as possible and avoid self-medication.

How to protect yourself from poisonous fish?

You can prevent an encounter with poisonous fish using these simple tips:

• do not touch unfamiliar fish or attract them;
• carefully study your route and the habitat of dangerous fish;
• do not swim too close to the seabed, rocks and reefs, refrain from exploring crevices between corals and rocks;
• if you are an avid diver, then buy a reliable wetsuit for additional protection;
• in potentially dangerous places it is better to wear special rubber shoes to protect the foot;
• While in the water, carefully step along the bottom, checking the places where you are going to stand.

Remember that a poisonous fish is much more afraid of you than you are of it, but in case of danger it will use all means of defense available to it. Be careful and your yacht cruise will be pleasant and uneventful.
