Effect of electrical stimulation used in the pulse trawl fishery for common sole on internal injuries in sandeels
Abstract Electric stimulation was used in the North Sea beam trawl fishery for common sole to reduce its environmental impact. Because electrical stimulation may cause internal injuries in fish, a laboratory experiment was conducted to study the effect of pulse exposure on lesser sandeel (Ammodytes...
