Lake Kasumigaura is the second largest lake in Japan. A long-term monitoring program has been conducted by National Institute for Environmental Studies, Japan. Fish and shrimp samples were monitored in cooperation with a local professional fisherman every 2 to 3 months since 2005. This data set includes 41 fish species and 3 shrimp species. These data are fishery-independent time-series data.
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.
