The efficiency of electric fishing for salmonids was found to decrease with increasing river width. The results demonstrated that mean efficiencies in excess of 50% could be obtained using two anodes up to a river width of about 6.5 m and using three anodes up to a river width of about 11 m. Yearling and older fish were captured more efficiently than fry at equivalent river widths and this was discussed in relation to differences in their behaviour.
