Solar Seastead as a Fish Aggregating Device (FAD)

Potential as a Fish Aggregating Device (FAD)

Your design is effectively a "Mega-FAD." Traditional FADs in Anguilla often use small buoys or palm fronds. Your seastead offers three critical attractors:

Structural Complexity: The four Duplex Stainless Steel floats and the web of tensegrity cables create a "reef" in open water. Small baitfish use these as shelter from predators.
Significant Shade: Pelagic species like Mahi-Mahi (Dorado) and Tuna are highly attracted to shade. A 16x40ft shaded area is a massive lure in the tropical sun.
Bio-fouling: Letting algae, barnacles, and bryozoans grow on the duplex floats is an excellent idea. This "living skin" creates a localized food chain, attracting small crustaceans, which attract baitfish, which attract the trophy fish you want.

Movement and Speed: 1 MPH vs. 0.5 MPH

In the Caribbean, pelagic fish are used to high-energy environments. 1 MPH is not too fast; in fact, it mimics the slow drift of Sargassum seaweed mats.

0.5 to 1.0 MPH: This is the "sweet spot." It allows the seastead to act as a moving ecosystem. At this speed, fish will likely swim with the structure.
The Propellers: Large 2.5m slow-turning propellers (40 RPM) are actually beneficial. The low-frequency vibrations can mimic the sound of struggling fish or biological activity, which curious predators like Marlin or Wahoo may investigate.

Growth and Timing

How long until you can harvest?

Initial Attraction: Within 12–24 hours of being in deep water, curious pelagic fish will investigate the shade.
Established Ecosystem: It takes about 2 to 4 weeks for a significant "resident" population of baitfish to bond with the structure. Once the baitfish are there, the larger predators will be nearby constantly.

Optimal Routes and Deep Water

To maximize your FAD's effectiveness in Anguillian waters:

Deep Water is Key: Pelagic FADs work best in depths of 1,000 to 3,000 feet. This is where big Mahi-Mahi, Tuna, and Wahoo migrate.
Distance from Land: Staying 5–10 miles offshore usually yields better "blue water" fishing, away from the pressure of coastal small-boat fishermen.
Current Lines: Try to move the seastead along current "rips" or temperature breaks. Your seastead will naturally collect floating debris and seaweed at these points, doubling its attracting power.

Night Fishing and Chumming

The Night Light Strategy: Aiming high-output LED lights into the water at night is incredibly effective. It attracts zooplankton, which attracts flying fish and squid, which bring in the large predators. You may find the best fishing is actually at 9:00 PM or 4:00 AM right under the lights.

Chumming Scraps: If you throw fish scraps into the water:

Timing: Fish right away. Pelagic fish have high metabolisms and move fast. The scent trail dissipates quickly as you move.
Strategy: Use the cameras to see if "scouts" are present. If you see one or two fish on camera, toss a handful of chum to trigger a "feeding frenzy" before dropping your hook.

Estimating the Catch

If you are in deep water and have an established bio-growth on your floats:

The Goal: One 5lb+ fish per day.

With underwater cameras and a baited line ready to go, catching a fish could take as little as 5 to 15 minutes once you spot them on the monitor. On a slow day in the Caribbean, you might spend an hour, but the beauty of a seastead FAD is that the fish come to you while you are working or relaxing.
