Atlantic Moonfish

To successfully capture the Atlantic Moonfish on an AI-powered underwater camera, placement is the most critical factor. These fish prefer the mid-water column in shallow coastal areas, so mounting your camera to a dock piling or a submerged reef structure at a depth of 2 to 5 meters (6 to 15 feet) is ideal. Because of their mirror-like skin, angling the camera slightly downward—away from the direct glare of the sun—will prevent 'white-out' reflections that can confuse AI identification algorithms.

Using a bait lure or a 'chum' dispenser is highly recommended to bring these schooling fish into the camera's field of view. A mesh bag filled with crushed oily fish or shrimp will attract the smaller baitfish that Moonfish hunt. Once a school finds a food source, they tend to linger and circle the area, providing the AI with multiple angles of their distinctive disc-shaped profile. Avoid using high-intensity white LEDs at night, as the reflection off their silver bodies can overexpose the image; instead, use low-glow infrared (IR) for nocturnal activity.

Seasonal timing significantly impacts your success rate if you are outside of the tropics. In the Mid-Atlantic and Northeast U.S., wait for the late summer months when water temperatures are at their highest and the fish move closer to shore into bays and estuaries. During these times, look for 'slick' water days with high visibility. Setting your camera's trigger sensitivity to high is beneficial, as the Moonfish's thin profile may not always trigger motion sensors when swimming directly toward the lens.
