Introduction of the "Terraced Fishway" case: Fishway design/construction on the Neo River in Gifu Prefecture.
[Case Study] Improving upstream migration efficiency with a unique design! The terraced fishway solves the issues of traditional fishways.
In conventional fish passages, there were challenges such as difficulty in guiding fish to upstream routes and sediment accumulation within the fish passage, which reduces its functionality. These issues are addressed by Yamatazumi's "Terraced Rice Field Fish Passage," which features a unique shape utilizing natural stones. We also provide explanations about the terraced rice field fish passage, consultations on fish passage design (such as creating drawings and quantity calculation sheets), proposals, and assistance, so please feel free to contact us. 【Case Study】 ■Project Name: 2008 Neogawa Bed Stabilization Improvement Project ■Location: Neogawa River (Kamikakichi, Ono Town, Ibi County, Gifu Prefecture, and others) ■Construction Photos: Please see the construction photos on this page. 【Reasons to Choose the "Terraced Rice Field Fish Passage"】 ■Fish can ascend from any direction due to its 180-degree accessibility, preventing fish stagnation. ■It has a maintenance-free structure that prevents sediment accumulation inside the fish passage. ■Thanks to its unique structure that can adapt to changes in water levels, it allows water to flow from the collection ditch directly beneath the bed stabilization during low water periods. ■By realizing the concrete secondary productization as terraced rice field fish passage blocks, we have achieved stable quality and simplified construction for the fish passage. *For more details, please contact us or download the catalog to view.
