Title:Fish monitoring data in Lake Kasumigaura
Identifier:JaLTER-Kasumigaura.1.31
Abstract:
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 42 fish species and 3 shrimp species. These data are fishery-independent time-series data.

Sampling, Processing and Quality Control Methods

Step by Step Procedures
Step 1:
Description:

The method to collect lake fish

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.

Step 2:
Description:

Fish identification and measurements

The samples were identified to the lowest possible taxonomic unit and the number of individuals of each species was counted.
