Description
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 45 fish species, 3 shrimp species and 1 frog species. These data are fishery-independent time-series data.

Sampling Methods
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. The samples were identified to the lowest possible taxonomic unit and the number of individuals of each species (ind./day) was counted. The wet mass of each species (wet mass(g)/day) was also measured. Note that additional nets to prevent intrusion of channel catfish were used for certain data which can be filtered by eventRemarks.
| Study Extent | Fish and shrimp samples were taken from the southeast shore of Lake Kasumigaura (near the Dosakibana in Inashiki city) every 2 to 3 months. |
