Fish do not feel pain the way humans do. That is the conclusion drawn by an international team of researchers consisting of neurobiologists, behavioural ecologists and fishery scientists. One contributor to the landmark study was Prof. Dr.
Do fish feel physical pain?
“Fish do feel pain. It’s likely different from what humans feel, but it is still a kind of pain.” At the anatomical level, fish have neurons known as nociceptors, which detect potential harm, such as high temperatures, intense pressure, and caustic chemicals.
Do fish feel pain when you hook them?
Fish have numerous nociceptors in their mouths and thus getting hooked is certainly a painful experience for them.
How do fish respond to pain?
First, behavioural responses to sensory stimuli must be distinguished from psychological experiences. Second, the cerebral cortex in humans is fundamental for the awareness of sensory stimuli. Third, fish lack a cerebral cortex or its homologue and hence cannot experience pain or fear.

Physiological responses to stress are grouped as primary, which include endocrine changes such as in measurable levels of circulating catecholamines and corticosteroids, and secondary, which include changes in features related to metabolism, hydromineral balance, and cardiovascular, respiratory and immune functions.
How many pain receptors do fish have?
The most sensitive areas of the body are around the eyes, nostrils, fleshy parts of the tail, and pectoral and dorsal fins. Rainbow trout also have corneal nociceptors. Out of 27 receptors investigated in one study, seven were polymodal nociceptors and six were mechanothermal nociceptors.
How do fish respond to stimuli?
Response to stimuli
Tapping on the tank or loud noises will cause the fish to dart away (startle response). An overactive or an underactive response may indicate a problem. When fish are caught to be transferred to another tank in preparation for breeding, their responses can be observed.
How do fish respond?
Fish is extremely sensitive to low-frequency vibrations, below some 10s of Herz. If the sound source is sufficiently intense, fish usually respond by swimming away from the source. The reason for this is probably that low frequency sounds usually indicates an approaching predator.
Do fish get happy when they see you?

Though few people know this, all fish respond to sound, and several recent studies have shown that fish can even tell the difference between genres of music and composers.
