Slaughter Methods
Tanks saturated with carbon dioxide have been used to make fish unconscious. Then their gills are cut with a knife so that the fish bleed out before they are further processed. This is no longer considered a humane method of slaughter. Methods that induce much less physiological stress are electrical or percussive stunning and this has led to the phasing out of the carbon dioxide slaughter method in Europe.

Famous quotes containing the words slaughter and/or methods:
“When offense occurred, Slaughter took the trail, and seldom returned with a live prisoner. Usually he reported that he had chased the suspect “clean out of the county”; these suspects never reappeared in Tombstone—or anywhere else.”
—Administration in the State of Ariz, U.S. public relief program (1935-1943)
“A woman might claim to retain some of the child’s faculties, although very limited and defused, simply because she has not been encouraged to learn methods of thought and develop a disciplined mind. As long as education remains largely induction ignorance will retain these advantages over learning and it is time that women impudently put them to work.”
—Germaine Greer (b. 1939)
