Default Can Fish Hear, And Do They Recognize Their People?

What do you think? Sometimes when I go to see them, they swim up to me.

I know what you'll say: "They swim over to you, because they want FOOD!"

Odds are its an asspociation of people =food.

I rarely if ever feed my koi in the mud ponds, and do have a koi or
two that routinely come up tp me if for nothing else than to get
their bellies etc rubbed...........

I do not think fish hear on the sense that humans hear., but they feel
what is making the noise or speech by way of vibrations in their
laterial line and sensory glands. To you and me soundwaves in water
are next to impossible to hear or distinguish, but just a slight
movement inthe water or the sound a single pellet of food makes when
it hits the water produces a loud enough sound to attract the
attention of the fish. I feed floating pellets to some of my sal****er
fish. One fish in particular you never ever see, as he is always deep
iside his rock cave or sand cave. I can toss justy 2 or 3 micro Hikari
pellets onthe water and that fast that fish is out of his cave and
pursuing the pellets. No way did the smell of those tiny pellets
permeate the water that quickly, which was virtuallay
imediately........so it had to be the sound and the vibration the
pellets made as they were dropped inthe tank. Your voice is nothing
more thana vibration or sound wave in another format to a fish and
yues they do tend to associate that sound pattern or form with food or
at least with the person or a person which usuallay does result ina
treat or in a feeding. Its a learn by association trait and most
critters can learn this in short order.

Fish hear through that mechanism. Scientific studies demonstrate the
ability to respond to different frequencies of sound with different
behaviors.

My Koi and Rosy-Barbs in my pond come and try to eat the skin off my fingers.
Luckily I don't stock Piranhas.

Yes, fish can hear and more.
Here's some fun facts.
Forums are a great way to learn about ponds and koi. Here's some
interesting facts about koi to pass the time. What other fun facts do
you know?

Koi Can Taste: They have taste buds almost everywhe On their lips
Within their mouth cavity Their fleshy barbels (2 in each corner of
the mouth) bear numerous taste buds and are highly sensitive to touch
Most of their bodies are covered with innumerable taste buds,
including their fins and tail

Koi Can Smell: The lining of the olfactory or nasal organ in Koi has
special sensory cells to function as smell receptors.

Koi Can Blush: Koi show stress by blushing red in their fins and on
their bodies. When they are handled in a net you can see the red in
their fins, between the spines. Also when they are in a stressful
environment, such as bad water, they will often show a red blush on
their bodies under the scales. Sometimes they almost look like they
have varicose veins. Often seen as red in the front spines of the
dorsal fin, and on the caudal fin. If you see this they are trying to
tell you something is causing them stress. Take measures to relieve
the stress or you will start to lose Koi. This is similar to when we
blush from embarrassment or stress.

water is a better conductor of sound than air.
"We know very little about whale communications. That is why we are looking for
patterns of association and coordination. The problem is that the whales are spaced
so far apart," says Clark. However, the SOSUS system is providing a wealth of new
data. In weeklong soundings at the U.S. Navy's Joint Maritime Facility in St. Mawgan,
Cornwall, England, Clark has obtained thousands of acoustical tracks of singing
whales for the different species throughout the year. "We now have the ability to
fully evaluate where they are and how long they sing for," he says. "We now have
evidence that they are communicating with each other over thousands of miles of
ocean. Singing is part of their social system and community."

Goldfish and koi have regular ears as well as the lateral line sensitive to changes
in water pressure. one of the reasons we never bang on ice or it will shock and/or
kill the fish. http://www.coloradokoi.com/koi_hearing.htm

my koi hear me coming and are at the surface and sucking for food before I even get
to the pond. Ingrid

If you clean your hands well (lots of people are staph carriers and fish get staph
from people) and hand feed your goldfish they will swim thru your hand. GF and koi
are not like other fish, they are PETS and act like pets. there are people who have
taught their GF TRICKS!!!!!
