Pet Forum / Aquaria / Goldfish / March 2008Can 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!" > What do you think?

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........... > > What do you think?

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 saltwater 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. > On Mar 8, 2:03 pm, Romanta...@webtv.net (L u) wrote: > [quoted text clipped - 7 lines] > two that routinely come up tp me if for nothing else than to get > their bellies etc rubbed........... Fish hear through that mechanism. Scientific studies demonstrate the ability to respond to different frequencies of sound with different behaviors. 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 http://jeb.biologists.org/cgi/content/abstract/61/1/243 http://www.ncbi.nlm.nih.gov/pubmed/17050834 my koi hear me coming and are at the surface and sucking for food before I even get to the pond.

My Koi and Rosy-Barbs in my pond come and try to eat the skin off my fingers. Luckily I don't stock Piranhas. -Hank 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 everywhere: 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. 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!!!!! >You mean they let you touch them? How cute! |
