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.
