Anatomical evaluation of the organs in the red swamp crayfish, Procambarus clarkii, by diagnostic ultrasound examination

We describe the ultrasound examination of the cephalothorax and pleon in red swamp crayfish. Real-time B-mode, Color and Power Doppler examinations were performed on 10 crayfish, Procambarus clarkii (Girard, 1852). We envisage that use of this technique will provide baseline information for further imaging studies to investigate the cardiovascular and digestive physiology and can be applied to identify disorders in crayfish, to say nothing of use in other crustaceans.
