All these assumptions are wrong. There is sound scientific evidence pointing to the capacity of fish to feel pain and stress. Furthermore, the environmental damage caused by both ocean fishing and the production of salmon and trout in factory farms is massively polluting as well as being responsible for denuding the world's oceans of once plentiful fish species. These practices also endanger many other sea and land-dwelling species who have hitherto depended for their existence on the fish plundered by human beings. FISH DO FEEL PAIN Increased heart rate, increased breathing rate, adrenaline rush, writhing, gasping - fish display similar signs to humans when under stress and faced with dangerous situations.
Fish feel pain out of biological necessity, just as all mammals do.
They possess a brain, central nervous system and pain receptors all over their bodies. Without the ability to feel pain they would not survive. They also produce enkephalins and endorphins, chemicals known to counter pain in humans. Scientific reports from around the world substantiate these basic realities and, thereby, underscore the cruelty and suffering inherent in the catching and killing of fish. Evidence that the term pain is applicable to fish comes from anatomical, physiological and behavioural studies whose results are very similar to those of studies on birds and mammals.
