can a fish smell under water?

better than we can smell up here in the air. it's one of the main senses they use for finding food and evading danger.

Seaman? Obvious answer! If it smells of fish then he's been there lol

Yes. But then you'd have to breathe in after that, which is not a good idea when under water.\n\nTry this experiment in the bath: inhale, blow the baloon, and then surface for air.

In smell yes ortherwise ?

yes.\n\nthey are mammals and do not breathe underwater.\n\nthey take in air at the surface, so it does not matter what type of water they live in.

Guppies don't really hear... And if they did, it wouldn't be by their gills. They use their gills to breathe. Instead, they follow vibrations. I'm not quite sure how, but I think they have a sense organ that detects vibrations in the water.

If a female has bad odor in the "southern regions" especially if it's "fishy" then she has something wrong and needs to be checked right away even if she has tried bathing and other things to get rid of it.  Smells are often an indicator of infection.  Unless of course she eats something fishy and then touches her "southern regions" without washing her hands!

It can be sucked in through the gills but it gets spit back out that way as a fish normally breathes.  The natural flow of water through the gills is due to swimming in that direction - the water naturally flow in the direction front to back.  Its not benefitting the fish to suck it in that way.

Put a fish in the water and see if it dies, if it doesnt then there is oxygen in the water. If it does then shame you have to buy another fish!!!

They smell, even, before they pop. You would have to intercept them to find this out. . . . and, indeed, they do smell even after they pop (or is it poop?). \n\nThe only thing the water does is cool them down a bit. The temperature of a fart at inception is 98.6 degrees and maybe let a little diffuse into the water (but not much).\n\nAn interesting little fact is that when you detect odors you are actually getting a tiny bit of whatever you are smelling in your nose (hmmm?).\n\nGotta let this go now.

Yes, there is no light at the bottom of the ocean. Fish are extremely small, measureing about 3 to 6 inches and are bioluminecent - meaning they glow in the dark. For several reasons: Attracting food - other unsuspecting fish, or for mating. It is not easy finding a mate at the bottom of the ocean. The fish are small because food is scarce so potential for growth is naturally limited. The fish's eyes are usually large in proportion to the body size to allow the maximum amount of light in for vision, if they have eyes at all. There is snow, but not the kind you and I might know, it is called marine snow. It falls just like snow on land, and never stops. This consists mainly of tests, or shells, from dead marine organisms from the above waters, or organic matter. Organic matter is anything that contains carbon. The bottom of the ocean is a cool place. Have you heard of hydrothermal vents? They contain chemosynthetic organisms that obtain energy by breaking down inorganic chemicals. Humans rely on the sun for producing all of our energy. Well anyways I am rambling. But I like it.\n\nAlso remember at the bottom of the ocean there is pressure, much more than you feel at the surface of the earth. Thousands of pounds of pressure pushing in from all directions. Squish, squish.

none water is H2O two parts hydrogen 1 part oxygen any thing else the water is inpure.but in the case of fish do a 1/4 water change every week so not to shock your fish make sure you keep temp about 78 degrees or they can get ick as far as testing you dont have to test fresh water but salt water is where the nitrite cycle is critical and then you also will test ph which is idealy 8 use a hydrometer to the line as it mesures the salt level by the boyency of the device nitites no higer than 14 i belive ask you pet shop owener as it been abuot 10 years since i had my salt water tank but for fresh water, the water change should cover it.

I would say no, since dogfish are a marine (salt water) 'fish' & catfish are fresh water fish

A toothbrush or fine steel wool.\nClean them in the water you are fishing and don't use any cleaners.\nResidue will have a unnatural scent.\nOk if you must use a cleaner try baking soda on a wet rag(wet in the water you are fishing)\nIf they are really cruddy do as above with salt then rinse well to prevent corrosion.

Yes, dogs can smell it.  So can humans. I can smell it a mile away..before and after diagnosis.....on the breath...a faint body odor. But then, I'm a nurse of 38 years.

It really depends on how warm the water is, some fishes (different species) do thrive in warm climate/ water
