Cobertura Geográfica
The study area consists of four rivers (Midai River, Ara River, Kane River, and Omo River) flowing through the Kofu Basin in the central part of the Japanese archipelago, within the Fuji River system. All of these rivers form alluvial fans, and the study focused on locations with similar riverbed gradients.

Dados Sobre o Projeto
The database is sampling results of fish fauna in river channels on alluvial fans in the Kofu Basin (Japan).

| Financiamento | This research was funded by the Research Fund for the Fuji River provided by the Ministry of Land, Infrastructure, Transport and Tourism. |
| Descrição da Área de Estudo | The study area is located within the Fuji River basin, which flows through the Fossa Magna zone, the boundary between the ichthyofaunas of southwestern and northeastern Japan (Itsukushima, 2019). The study sites consist of 26 locations across four tributaries—Midai River, Ara River, Kane River, and Omo River—within the Kofu Basin, each exhibiting distinct watershed characteristics. These four rivers, which all have alluvial fans, are formed by different geological substrates: Midai River by basalt, Ara River by granite and rhyolite, Kane River by diorite, and Omo River by granodiorite. Of the 26 study sites, 17 have undergone recent riverbed dredging, while 9 have not. |

Métodos de Amostragem
Fish surveys were conducted using an electrofisher (Smith-Root Model 12-A, Smith-Root Inc., Vancouver, WA, U.S.A.) at each study site. The survey length was generally set to one reach (approximately ten times the width of the river). The collected fish species were identified on-site and released immediately. Additionally, the wet weight of each species was measured at each site. In this research, we recorded 416 occurrence data and they were identified on-site and laboratory according to Kawanabe and Mizuno (1989) and Seno (2007).

Descrição dos passos do método:
- 1. Data Collection. Field surveys were conducted from October 22 and 29, 2024 in the Kofu Basin, Japan sites. Fish surveys were conducted using an electrofisher (Smith-Root Model 12-A, Smith-Root Inc., Vancouver, WA, U.S.A.) at each study site. The survey length was generally set to one reach (approximately ten times the width of the river). The collected fish species were identified on-site and released immediately. Additionally, the wet weight of each species was measured at each site. In this research, we recorded 416 occurrence data and they were identified on-site and laboratory according to Kawanabe and Mizuno (1989) and Seno (2007). 2. Data Quality Control All specimen identifications were double-checked by taxonomic experts. Duplicate records were removed during data cleaning, and GPS coordinates were verified for accuracy using mapping software (QGIS). 3. Data Processing Coordinates were converted to the WGS84 coordinate system. Taxonomic names were standardized according to GBIF's taxonomic backbone. All measurements were recorded in metric units. 4. Metadata Creation The dataset was described using the Darwin Core standard, including attributes such as location, date of collection, and identifiers. 5. Data Publication The dataset was uploaded to the Pensoft IPT platform and published under the Creative Commons Attribution 4.0 International license (CC-BY 4.0). 6. Data Use This dataset is available for non-commercial use, and users are required to provide proper attribution when using the data in their publications.
