Are Fish Attracted to Light at Night?: Your Fast-Track Guide to Understanding Fish Behavior

Many people who enjoy night fishing have noticed that fish often congregate around sources of light, such as dock lamps or underwater LEDs. Scientifically, the answer is yes—fish are attracted to light at night, but the reasons and effectiveness can vary by species and environment. Light penetrates water and attracts plankton and small aquatic insects, which in turn draw in baitfish and larger predatory fish. For this reason, anglers frequently use light as a strategic tool to improve their chances of catching fish after dark.

Tips 1:

As an interior designer, I find there’s a parallel with how we use lighting in home design to draw attention to focal points or create mood. Just like in aquatic environments, the right lighting plan in a living room or workspace can define the atmosphere and guide movement within a space. When planning your next room makeover, consider how different types of lighting fixtures and positioning can create dynamic appeal—much like a well-placed underwater light attracts fish.

FAQ

Q: Why are fish attracted to light at night?

A: Light attracts plankton and insects, which in turn draw smaller baitfish. Larger predatory fish then follow these food sources, making lighted areas rich fishing spots at night.

Q: Does the color of the light matter for attracting fish?

A: Yes, different colors can affect attraction rates. Green and blue lights are commonly used because they penetrate water better and attract more plankton.

Q: Is using light to attract fish legal everywhere?

A: Regulations vary by region; some places restrict artificial lights for fishing, so always check local laws before using them.

Q: What types of fish are most attracted to light at night?

A: Many species, including bass, crappie, and squid, are drawn to illuminated areas, but the effectiveness varies with location and season.

Q: Can I use regular household lights to attract fish at night?

A: Submersible LED lights or specialized fishing lights work best, as household lights are not waterproof and may not emit the optimal wavelength to penetrate water and attract aquatic life.
