・Since the ceramic pipes ideal for giant pacific octopus spawning are secured with concrete, they are resistant to damage and burial, ensuring they
function effectively as spawning reefs.
・Because both ends of the pipe are open and allow good water flow, it promotes the growth of the eggs.
・The pipes are arranged in various directions, making it easy for giant Pacific octopuses to lodge themselves and suitable for their territorial
nature.
・The gap between the two stacked upper and lower blocks provides an environment suitable for shellfish, which are the prey of the giant Pacific
octopus.

π Block(Settlement substrate for rocky shore resources)
・Its low center of gravity and shape, which excels in stability and wave resistance, make it possible to create seaweed beds and breeding grounds in
shallow waters.
・It has a large attachment surface, making it effective for the settlement and growth of floating larvae such as seaweed spores, eggs, and
shellfish, and demonstrates excellent propagation effects.
・It is possible to install 'Culbase,' a feed cultivation substrate recycled from seashells.

SGBlock(Barrier reef)
・The blocks have a low center of gravity and a shape that excels in wave resistance and stability.
・Since the height is uniform, it is possible to securely enclose the stone without gaps, and it has an appropriate leg length, allowing it
to adapt to uneven terrain.
