Is fish pain a reality? Opinions among scientists are divided.


Fish have long been debated as to whether they can feel pain, with animal rights organization PETA claiming that they do, while other scientists, such as Ana Zangroniz, argue that what people perceive as pain in fish is actually a response to stress. The anatomy and physiology of fish make it difficult to determine if they can feel pain, as they cannot be compared to mammals or birds. Some studies have shown that fish exhibit changes in behavior and avoid stimuli that could cause pain, while others argue that fish do not have the neural tissue required to sense pain.

The level of pain that fish may experience is still unknown, as studies only focus on a few species of fish out of the thousands that exist. While fish may visibly respond to stress or unpleasant stimuli by swimming away, it is difficult to determine if they are in pain. Removing stressors from a fish’s environment or consulting a fish health specialist may help alleviate potential discomfort in pet fish. Releasing pet fish into local aquatic settings is not recommended, as they may be exotic species that could become invasive.

Ultimately, the debate over whether fish feel pain is ongoing, and there is still much to learn about the cognitive abilities of these aquatic creatures. Studies continue to explore this question, but for now, the answer remains elusive.
