The short answer is yes, blue underwater lights do attract fish. But how and why do they work? And what are the benefits of using them for fishing or boating? In this article, we will explore the science behind blue underwater lights, the types of fish that are attracted to them, and the best practices for using them effectively.
Blue underwater lights work by taking advantage of two natural phenomena: phototaxis and bioluminescence. Phototaxis is the tendency of some organisms to move toward or away from a source of light. Bioluminescence is the ability of some organisms to produce and emit light.
Many fish and other marine creatures are phototactic, meaning they are attracted to light. This is because light can indicate the presence of food, mates, or predators. Some fish are also bioluminescent, meaning they can produce their own light. This can help them communicate, camouflage, or lure prey.
Blue underwater lights mimic the natural light conditions of the ocean, especially at night. Blue is the color that penetrates the deepest in water, and it is also the color that most bioluminescent organisms emit. Therefore, blue underwater lights can attract fish that are used to seeing blue light in their environment.
The Types of Fish That Are Attracted to Blue Underwater Lights
Blue underwater lights can attract a variety of fish, depending on the location, depth, and time of the year. Some of the common fish that are attracted to blue underwater lights are:
Snook: Snook are a popular game fish that are found in tropical and subtropical waters. They are nocturnal and feed on smaller fish, shrimp, and crabs. Snook are attracted to blue underwater lights because they can see the silhouettes of their prey against the light.
Tarpon: Tarpon are another popular game fish that are found in warm and brackish waters. They are known for their acrobatic jumps and powerful fights. Tarpon are attracted to blue underwater lights because they can spot the movements of their prey in the dark.
Squid: Squid are not fish, but they are a common sight around blue underwater lights. They are cephalopods that have eight arms and two tentacles. They are also bioluminescent and can change their color and pattern. Squid are attracted to blue underwater lights because they can use them to hunt or avoid predators.
Plankton: Plankton are microscopic organisms that drift in the water. They are the base of the marine food chain and are eaten by many fish. Plankton are also bioluminescent and can produce blue light. Plankton are attracted to blue underwater lights because they can use them to find each other or escape predators.
The Best Practices for Using Blue Underwater Lights
Blue underwater lights can be a great tool for fishing or boating, but they also require some care and caution. Here are some tips for using blue underwater lights safely and effectively:
Choose the right type of blue underwater light for your purpose. There are different types of blue underwater lights, such as LED, halogen, or fluorescent. LED lights are the most energy-efficient and durable, but they can also be more expensive. Halogen lights are the brightest and cheapest, but they can also overheat and drain the battery. Fluorescent lights are the most balanced and versatile, but they can also be fragile and bulky.
Install the blue underwater light properly and securely. The blue underwater light should be mounted on the stern or the side of the boat, below the waterline. The light should be angled downward and outward, to create a wide and deep beam. The light should also be attached firmly and waterproofed, to prevent any damage or leakage.
Use the blue underwater light sparingly and responsibly. The blue underwater light should be used only when needed, and not left on for long periods of time. The light can attract unwanted attention from other boaters, wildlife, or authorities. The light can also disturb the natural behavior and balance of the marine ecosystem. The light should be turned off when not in use, and disposed of properly when no longer needed.
Conclusion
Blue underwater lights are a fascinating and useful invention that can enhance your fishing or boating experience. They can attract fish and other marine life by mimicking the natural blue light of the ocean. They can also create a beautiful and mesmerizing effect on the water. However, they also require some knowledge and caution, to avoid any harm or trouble. By following the guidelines and tips in this article, you can enjoy the benefits of blue underwater lights safely and responsibly.
