Yes, fish can hear you talk! Sounds that are created above water typically do not carry enough force to penetrate the surface tension of the water, so talking on the boat or loud noise may not affect fish as much as your fellow anglers may want you to think. Your voice is unlikely to spook or scare fish away.
The answer is yes! They can. Although their hearing apparatus may work rather differently from our own, wild and aquarium fish tend to be very good at hearing sounds.
Besides being able to see their prey and recognize their owners, fish also can see a range of colors, since they have color receptors in their eyes. Many species of fish can also see ultraviolet light, which humans can't. In fact, ambon damselfish have UV markings on their faces, which only they can see.
You may be surprised to learn that the answer to this question is actually yes! Goldfish can hear sounds even though they don't have ears!
Researchers have found that fish recognize each other and gather information by eavesdropping. They're capable of remembering past social interactions that they've had with other fish, and they show affection by rubbing against each other.
What they found was that both the female and the male she had chosen were slower to spawn and became a little more glum. This shows us that fish do feel companionship and that it's not just humans or mammals, so love really is in the water!

While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.
Yes, fish experience both physical and emotional pain. Scientists say that it's likely a different type than what humans experience, but it's pain nonetheless. Fish have nerve cell endings called nociceptors, which alert their bodies to potential harm such as high temperatures, intense pressure, and harmful chemicals.
It is popularly believed that fish have a memory span of only 30 seconds. Canadian scientists, however, have demonstrated that this is far from true -- in fact, fish can remember context and associations up to 12 days later. It is popularly believed that fish have a memory span of only 30 seconds.
Scientists have just observed a thought swimming through the brain of a live fish, and that thought concerned getting something good to eat. Fish and other wild animals appear to think a lot about food: how to obtain it and what to consume.
Like humans, even fish have instinctual feelings. They are very alert to their surroundings, and sudden movements irk them a lot. So, when they detect motion in the form of you, they will try to look at the source. Of course, it doesn't mean anything, but it enables you to bond with your betta.
Noise which can disturb the natural behaviour of fish
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.
Nerves, brain structure, brain chemistry and behaviour – all evidence indicates that, to varying degrees, fish can feel pain, fear and psychological stress.
Researchers from Keio University in Japan have studied the effects of playing music for fish kept in indoor glass tanks and outdoor koi ponds, and one of the conclusions was that fish can not only hear music but also react to harmonious sounds.
Fish have gills that allow them to “breathe” oxygen dissolved in the water. Water enters the mouth, passes over the gills, and exits the body through a special opening. This keeps an adequate amount of water in their bodies and they don't feel thirsty. Ask your own question!
Freshwater fishes have to *get rid* of water constantly to keep their cells from bursting, which means they pee *a lot*. They're pretty much peeing all the time. If I peed as much as a freshwater fish, I'd release up to 28 liters a day, which is about 20 times more pee than I usually make.
The specialised retinas of some nocturnal coral fish result in faster vision and greater sensitivity to dim and bright light. The same adaptation may enable deep-sea animals to see in darkness.
Fish can recognise members of the same species and tell if other fish are siblings, but they probably can't identify themselves.
Fish don't really know they're wet. But what about you? Have you ever thought that you might be immersed in an environment and not know it? Like fish are unaware of being in water, many Christians are just as unaware of the postmodern world they live in and the influence it has on their lives.
Most fish, both in freshwater and salt, detect sound from 40 Hz up to 500 or 1,000 Hz (though some, like salmon, only hear to about 400 Hz, while others, such as herrings, can hear to over 3,000 Hz). So most species have a range of hearing that's more limited than ours.
The wild wriggling and squirming fish do when they're hooked and pulled from the water during catch-and-release fishing isn't just an automatic response—it's a conscious reaction to the pain they feel when a hook pierces their lips, jaws, or body.
Rose states that they "display robust nonconscious, neuroendocrine and physiological stress response to noxious stimuli". In short, if you need to touch a fish, you should remember that the fish may (or may not) experience pain the way you do, but it undoubtedly does suffer from stress.
When a fish establishes a territory, it will chase away any other fish it sees as a threat. This is not only stressful for the fish being chased but also for the fish doing the chasing, which is always in fight mode. Some fish look to establish dominance over others of their species or even fish of other species.
