Fish Feelings and Behavior
Fish have brains resembling human brains and evidence suggests they feel fear. They use senses similarly to humans, with sight and smell being most important. Fish communicate through movement, sound, and scent, indicating some form of emotion. Studies show they likely have feelings, but more research is needed. Fish exhibit reflexive responses to harm, but determining pain is challenging. Some believe fish have emotions like love and care for mates and offspring.
Fish Pain Perception
Studies show that fish demonstrate pain-related behaviors after being hooked. The debate about fish pain perception continues. Fish possess neurons called nociceptors that detect harm and have the biological tools to feel pain. They suffer when suffocating, exhibiting behaviors similar to other animals experiencing pain.
Fish Suffocation and Pain
Fish out of water slowly suffocate and experience pain, likely comparable to drowning for humans. Cod and haddock have been found to remain conscious for prolonged periods on fishing ships, going against humane standards. Overall, understanding fish pain and suffering requires further research and ethical considerations.
