Studies indicating that fish can feel pain were confusing nociception with feeling pain, says Rose. "Pain is predicated on awareness. The key issue is the distinction between nociception and pain. A person who is anaesthetised in an operating theatre will still respond physically to an external stimulus, but he or she will not feel pain."
What level of pain do fish feel? That, too, is unknown. Zangroniz said studies only use a few species of fish and don't represent the more than 30,000 fish species that exist.
Rose had published a study a year earlier arguing that fish cannot feel pain because their brains lack a neocortex. [38] However, animal behaviorist Temple Grandin argues that fish could still have consciousness without a neocortex because "different species can use different brain structures and systems to handle the same functions."

Scientists called for humane ways to handle crabs, lobsters, and other shellfish in the kitchen after showing for the first time that crustaceans indeed feel pain.
Emotional pain is the pain experienced in the absence of physical trauma, e.g. the pain experienced by humans after the loss of a loved one, or the break-up of a relationship. It has been argued that only primates , including humans , can feel "emotional pain".
“It’s just crazy to see something that, growing up, you go to the fair and you get a little goldfish in a bag. All of a sudden, you’re seeing one 14, 15 inches long,” he said. It’s not ...

Goldfish released into the wild have become an invasive pest in parts of North America and Australia. [4] [5]
