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. 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.
