Fish Suffer Too
Fish experience pain and distress just like other animals. They are intelligent, have long-term memories and individual personalities, and they live in sophisticated social groups.
In their native environment salmon start life in fresh water, migrate out to sea and spend most of their life travelling huge distances, using their sophisticated navigation skills to return home to spawn. In contrast, the lives of farmed salmon are manipulated from birth to slaughter, and all their natural instincts are thwarted.
In fish farming huge numbers of fish are crammed into unacceptably small spaces. Overcrowded cages deprive salmon of the freedom to swim long distances and carry out natural social behaviours. A 2.5-foot fish can spend his entire life in a space the size of a bathtub. Physical injuries, abnormalities and blindness are common. Keeping large numbers of fish in crowded conditions also encourages the spread of infectious diseases and pests, especially sea lice.
Inhumane methods of slaughter
Salmon would naturally live about three to four years. Fish are routinely starved before slaughter for days to empty the gut. Approved slaughter methods include leaving the fish out of the water, electrical stunning and brain spiking. A few farming operations anaesthetise salmon before slaughter, but many do not.
