Fish Feel Pain
While it may seem obvious that fish are able to feel pain, like every other animal, some people still think of fish as swimming vegetables. In fact, regarding the ability to feel pain, fish are equal to dogs, cats, and all other animals. Dr. Donald Broom, scientific advisor to the British government, explains, "The scientific literature is quite clear. Anatomically, physiologically and biologically, the pain system in fish is virtually the same as in birds and mammals."
 Indeed, neurobiologists have long recognized that fish have nervous systems that comprehend and respond to pain, and anyone who made it through Biology 101 knows that fish have nerves and brains that sense pain, just like all animals. Indeed, scientists tell us that fish brains and nervous systems closely resemble our own. For example, fish (like "higher vertebrates") have neurotransmitters like endorphins that relieve suffering—of course, the only reason for their nervous systems to produce pain killers is to relieve pain. Claiming that fish do not suffer is as intellectually and scientifically sound as arguing that the Earth is flat.
Interestingly, scientists have created a detailed map of pain receptors in fish's mouths and all over their bodies. A team of researchers at the University of Guelph in Canada recently surveyed the scientific literature on fish pain and intelligence. They concluded that fish feel pain and that "the welfare of fish requires consideration." Dr. Lynne Sneddon, a scientist of fish biology in the United Kingdom, explains, "Really, it's kind of a moral question. Is your angling more important than the pain to the fish?"
Scientists at Edinburgh University and the Roslin Institute in the United Kingdom report that in response to pain, fish also feel emotional stress and engage in "a ‘rocking’ motion strikingly similar to the kind of motion seen in stressed higher vertebrates like mammals." The research team concluded that fish clearly experience pain in the same way as mammals, both physically and psychologically. A study by scientists at the Queen's University of Belfast proved that fish learn to avoid pain, just like other animals. Rebecca Dunlop, one of the researchers, said: "This paper shows that pain avoidance in fish doesn't seem to be a reflex response, rather one that is learned, remembered and is changed according to different circumstances. Therefore, if fish can perceive pain, then angling cannot continue to be considered a non-cruel sport."
As you would expect from animals who we now know to be intelligent and interesting individuals with memories and the capacity to learn, fish can also suffer from fear and anticipation of physical pain. Researchers from universities across America have published research showing that some fish use sound to communicate distress when nets are dipped into their tanks or they are otherwise threatened. In a separate study, researcher William Tavolga found that fish grunted when they received an electric shock. In addition, the fish began to grunt as soon as they saw the electrode, clearly in anticipation of the torment that Tavolga was inflicting on them.
According to Dr. Michael Fox, D.V.M, Ph.D., "Even though fish don't scream [audibly to humans] when they are in pain and anguish, their behavior should be evidence enough of their suffering when they are hooked or netted. They struggle, endeavoring to escape and, by so doing, demonstrate they have a will to survive."
What happens to fish before they end up on your plate is nothing short of cruelty to animals—whether they’re farmed
or pulled from the ocean, fish are treated in ways that would warrant felony charges if it were other animals who were so horribly abused. Please click
