Radiological changes during fracture and repair in neural and haemal spines of Atlantic cod ( Gadus morhua )
Abstract Although spinal injuries in fish have been associated with electric stimuli applied during electrofishing and electrotrawling, bone fracture and repair in the axial skeleton have yet not been studied. To study this, we radiographed a group ( n = 64) of individually tagged farmed cod twice,...
