For some years now the scientific concensus has been that fish feel pain. At the anatomical level, fish have neurons known as nociceptors, which detect potential harm, such as high temperatures, intense pressure, and caustic chemicals. They also produce the same opioids—the body’s innate painkillers—that mammals do. All over the world, every moment of every day, untold individual fishes suffer panic and undergo painful death through suffocation and injury because of our taste buds.
There are now widely available substitutes that mimic the texture and flavour of fish. There is no longer any excuse for torturing the denizens of the Ocean in order to eat them. Eating fish and other ‘seafood’ is also causing harm to sea mammals and marine ecosystems.
