Can fishes see electromagnetic fields?

[Wyld-Fyre]

I'm not a specialist, but I've heard that there are some species of fishes out there that can see, or is it feel, electromagnetic fields?

If so, I wonder how they would perceive this field. Would it be an oddball curiosity, danger, or a even a strange new animal?

What do you guys think?

I think that a fish's lateral line can pick up electromagnetic waves, or just feel vibrations

no, but they can feel them. this is a secret to catching fish if you have metal lure. get a really strong magnet, and rub it against the metal to magnitize it, you will get more bites. this why fish hang out under power lines

You can actually own a fish that produces these fields! They are called knife fish. Their thin tail gives off a pulse at a certain frequence to detect prey, and to get around in the murky water that they live in. They can also change the frequency if another knife fish is around and is at the same frequency as he is. And of course, if a fish emits them, they also can detect them.

Sharks and rays and such can also detect electromagnetic fields. The hammer head shark is a great example. He sweeps his head over the sand, scanning for food as all animals give off an electromagnetic resonance.

Yes, fishes can detect electromagnetic fields, but I'm not sure what the response to them is.

Look at this.

It's pretty interesting

Sharks, especialy, use elctromagnetic fields when looking for prey and will miss their target if there's a large metal object (such as a ship) very close to them. They use it because, as they attack their prey, they close their eyes with a special kind of eyelid and this means they need to rely on other senses to get their target. The 'nostrils' many fish have on their snouts is what they mainly use to detect these.

That article might also be saying don't play loud music near your aquarium-it could stress the fish out with the change in pressures.
