Fish Path SPIRAL

Fish Path SPIRAL

The method of stacking fishway blocks in an oval shape allows for a significant reduction in the site area.

■The method of stacking fishway blocks in an oval shape significantly reduces the site area. ■The product shapes used for the curved and straight sections are standardized, which enhances workability. ■By creating a track shape with straight sections between the semicircular parts, the flow conditions in the pool are adjusted to facilitate fish ascending. ■The slope of the fishway has the semicircular return section at level and the ascending straight section at a gentle slope of 1/10, improving the ascent efficiency compared to a circular shape. ■The partition wall adopts an ice harbor method that accommodates small fish species. ■By rounding the shape of the overflow section of the partition wall, it creates a submerged flow that is easier for fish to ascend. ■Overflowing at the fishway outlet section allows for adjustment of the fishway flow rate. ■Light windows are installed to ensure adequate illumination.

Terraced Fishway: Jointly Developed Patent Fishway with the Chubu Regional Development Bureau of the Ministry of Land, Infrastructure, Transport and Tourism

Terraced Fishway: Jointly Developed Patent Fishway with the Chubu Regional Development Bureau of the Ministry of Land, Infrastructure, Transport and Tourism

The unique shape is effective for upstream migration! The terraced fishway has solved the issues faced by conventional fishways!

In traditional fish passes, there were challenges such as difficulties in guiding fish to upstream routes and the accumulation of sediment within the fish pass, which reduces its functionality. These issues are addressed by the unique terraced fish pass that utilizes natural stones. We also provide explanations about the terraced fish pass, consultations on fish pass design (including drawing creation and quantity calculation), proposals, and assistance, so please feel free to contact us. 【Features】 ■ Fish can ascend from any direction thanks to the 180-degree design, preventing fish from lingering. ■ It has a maintenance-free structure that prevents sediment accumulation inside the fish pass. ■ The unique structure can accommodate changes in water levels, allowing water to flow from the collection ditch beneath the solid floor during low water conditions. ■ By realizing the concrete secondary productization as terraced fish pass blocks, we have achieved stable quality and simple construction for the fish pass. ■ By installing it as an auxiliary fish pass next to existing protruding fish passes, fish ascension can be made more effective. ■ Research has confirmed that not only swimming fish like sweetfish and amago but also bottom-dwelling fish like red crucian carp and gobies, as well as aquatic insects, utilize it. *For more details, please request materials or view the PDF data from the download section.
