Methods

Please read additional terms of use associated with this dataset: https://db.cger.nies.go.jp/gem/moni-e/inter/GEMS/database/kasumi/contents/terms.html. Fish and shrimp samples were taken from Southeast shore of Lake Kasumigaura near the Futto (until 18-Jan-2017) and the Dosakibana (since 17-Mar-2017) in Inashiki city every 2 to 3 months. In cooperation with a local professional fisherman, we captured fish and shrimp using a large stationary net, which consists of three trap nets (70 cm in diameter, 6 m in length, 3 mm mesh size) and a leader net (80 m in length, 11 mm mesh size). The stationary net was washed out before sampling and was set for 24 h in a similar manner. Deployment and collection took place in the morning. The samples were identified to the lowest possible taxonomic unit and the number of individuals of each species was counted. These data are fishery-independent time-series data. Biomass is in grams.
