The construction and use of a holding box system for rainbow trout is described. The equipment was designed to take fish of up to 25 cm in length with ten fish in each independent tray unit. Fish can be exposed to experimental changes in water quality and individuals removed at random during an experiment without disturbance to the other fish. A mean total time of 2 min 17 s (± 1.8 s standard error; 200 fish) to remove, anaesthetize, weigh, measure and obtain a blood sample from a fish was achieved.
