can they hear?

Of course they do. You just can't see them. First, you need some sound facts. All sounds are made from vibrations, so hearing is really a kind of feeling. You can feel these sound vibrations, or waves, when you touch the outside of a ringing bell. Your ears "feel" sound waves, too. Nerve endings in your ears send messages to your brain about the sounds they feel. Sound moves through water the same way it does through air, so a fish actually "hears" water movement. The moving water flows through the skin at the back of the fish's head into its hidden ears (two hair-lined sacs that contain fluids) and moves the hairs in the lining. Scientists aren't sure, but they think tiny nerve endings attached to the hairs then send signals to the fish's brain. Most fish can't easily hear really high-pitched or low-pitched sounds. To help hear very low sounds, some fish use a special fluid-filled tube, called a lateral line, as a kind of built-in hearing aid. A line of tiny holes run along both sides of fish from their head to their back fin. Inside the holes are special nerve cells that sense movement, a lot like how the ear works. It doesn't look anything like an ear, but it helps fish "hear" or feel very low vibrations from moving objects -- like a bigger fish looking for lunch!

Although fishes have no external ears (their ears are inside their head), they still have a keen sense of hearing. Some fishes communicate by making sounds and listening for a response from a member of their own species.

While fishing is a hobby you might do better posting this question in zoology (under science & mathmatics).

They don't have external ears, but hear through their skin.

no ears, but can detect noise and movement vibrations in water

I have never pondered whether a fish can hear or not.
I know whales can hear.

I don't think so, because I've never seen one with earrings.

OO they can hear. The oceans are noisy as water transmit sounds.
