Size scaling of whole-body metabolic activity in the noble crayfish (Astacus astacus) estimated from measurements on a single leg

1. Use of electron transport system (ETS) activity in a single leg for estimating whole-body ETS activity was explored in the noble crayfish Astacus astacus. Oxygen consumption and ETS activity of the whole body and of a walking leg were measured in different-sized animals at 10 degrees C to compare the size scaling of oxygen consumption, whole-body ETS activity and the ratio of whole-body ETS activity to oxygen consumption (ETS/R).
