Gill wants consumers to know that fish raised in captivity are confined in crowded, unnatural conditions that cause stress, infection, and parasites. Fish farmers use antibiotics to decrease infection, and these and other chemicals accumulate in the fish's bodies and are passed on to those who eat them.

Seeking an easy meal, birds are attracted to fish farms, but many fish farmers shoot birds on sight to protect their profits. While fish cannot vocalize their pain and suffering in a way that humans can easily recognize, marine biologists tell us that fish feel pain. Fish begin to die slowly of suffocation the moment they are pulled out of the water.
