Abstract
The construction details of a device which allows unbiased sampling of fish for physiological studies are described. The device consists of two rectangular tanks connected by a tunnel which contains a trapdoor in the floor. A single fish swimming through the tunnel can be removed by opening the trap door; the tunnel is isolated from the two tanks by flap-valve doors when the trapdoor opens. Blood glucose and lactate levels of fish serially removed from the tank remain stable throughout the sampling day.Keywords
