FP Reef　"Fish Paradise Reef"

Features of FP Reef

○Because of the concrete structure, the function as an artificial reef will be maintained for a long period of time.

○Because it is composed of surface structural members, it has a large stimulating area for fish and a large settlement area for prey organisms and exhibits a high gathering and breeding effect.

○The diagonal members (cross arms) that intersect at the center generate a complicated vortex around the area, which provides an excellent gathering effect.

○Since it is a strong block that is integrated with the site by the molding unit leasing method, it is possible to create an effective habitat close to a natural fish reef by installing it in random piles

Standard
It has an extensive lineup that can meet various needs.
２．００type	３．００/３．２５type	３．３０type
４．００Ｒtype	５．００-Ｓtype	４．００・５．００type

Shallow sea	Breeding reef
Developed for the creation of breeding grounds in shallow waters with strong tidal current, it has a low center of gravity and improved wave resistance.	It is a small artificial reef suitable for random stacking installation with a small space corresponding to juvenile larvae and a large bioepiphytic surface.
ＦＰ１．５Ｇ/１．５ＧＢ	ＦＰ１．６Ｎ

Assembled reef Deep water
It is an artificial reef that has both the complexity and height of space by stacking FP Reefs. All are large-scale assembled artificial reef manufactured on-site, which contributes economically and to the promotion of local industries.

Seaweed epiphyte / feed culture substrate "Culbase"

Features of Culbase

○Due to its complex structure with high surface roughness, it promotes the adhesion of seaweed spores and eggs, making it ideal as a substrate for seaweed bed formation. In addition, it continuously exerts the epiphytic effect of seaweed.

○In the water-permeable voids inside the Culbase substrate, decapods (shrimp and crabs) and polychaeta (clam worms) that feed fish are naturally inhabited at an early stage. A suitable feeding environment for fish is formed. [Porosity 50-60% or more]

○The Culbase panel is a self-supporting panel structure supported by reinforced concrete, and since a large area can be designed in any shape, it is economical and can be attached to various fishing ground development items such as FP Reefs.

The effect of Culbase feed culture has been confirmed by demonstration tests all over the country.

	Since March 2018, it has been certified as an "Ishikawa prefecture eco-recycling certified product".

Top type
By attaching the Culbase panel, a large shaded space is formed inside the artificial reef, and it is effective as a protected breeding reef with a hiding place for fish larvae as well as the feed culture effect of Culbase.

Inner frame type	Shallow sea type
With a model that can be installed centrally or randomly, the feed culture function of the artificial reef group can be enhanced.	It is a feed culture type breeding reef for shallow waters with a Culbase panel attached to FP1.5G with high seakeeping resistance.
