Can a fish die of thirst?

I suppose if you took a fresh water fish and put him in the ocean, he wouldn't be able to deal with the salinity and would dehydrate - essentially die of thirst!!

that is a lung fish related to the mud fish cant leave water. \nif you foung it in amareca kill it it is alian to the US!!!!!!!!!!!!!!!!

No, stomach acids would kill it.\nI do not believe that whales can get it anyway.

Depending on the fish there could be different obstacles. Certain sharks must continually swim to pass water over there gills to not suffocate. Also in certain shallow water mangroves oxygen depleted water can be another obtacle (except for the lemon shark which can survive better in low oxygen water). I also believe polluted water, such as oil spills and the like, can be perhaps the biggest obstacle of all the fish will face in the respiration process especially around coastal areas.

Not sure about humans but high levels of nitrates can kill fish.  However if you're drinking water with that high of a concentration, it probably doesn't taste very good.\n\nGet a water filter.

A difficult question.\nThe two references below have something to say about whether or not fish feel pain. The arguement claiming 'Yes' is related to the evolution of survival behaviours and hard to refute. It does however hold true for any animal which responds negatively to stimuli.\nIt is certainly true that if you stick a pin into a maggot it will wriggle - it certainly does not like it. Fish are none too keen either.

Yes.  A little drink is perfectly harmless (unless it's during a red tide or it's polluted).\n\nIt's only a serious problem when you are unable to drink anything else (like in a liferaft without fresh water).  The high salt content wouldn't quench your thirst for long and would just increase the salt in your body (further dehydrating you) and make you sick.

No, not for very long.  Kidney failure in people is treated eventually by dialysis.  If the animal is in total kidney failure, it cannot live.  However, often kidneys do not fail completely, so the animal may live for a while, a few days or weeks, but not feel very well.\n\nThese links will give you more information about the implications of kidney failure.

If there is too little water the cell becomes dessicated and dies, if there is too much water the cell bursts.

Put in a plastic bag, make sure you leave holes in them, of course not at water level. Your fish will survive, don't worry. Fresh fish is better then dead ones.

ther are a few desert animals that can do that, but humans can not, we need water to digest the food we eat, you will die of thirst.

I think you mean pancreatitis. Yes, it can inflict animals. It is not caused by drinking too much water. It can be caused by eating the WRONG TYPES of food and by drinking alcohol

Not all fish do die when taken out of water. Some fish can survive indefinitely out of water provided they are kept moist with rain or dew.\n\nOf those fish that do die the most common cause of death is suffocation. \n\nFish mainly extract oxygen form the water through their gills. The gills of fish consist of hundreds of thousands of tiny strands, almost like hair. Have you ever seen someone with long hair underwater and noticed that the hair floats out from the head? Well underwater the gill filaments behave the same way. In the water those strands float apart and the fish is able to to extract oxygen from every one of them. \n\nWhen the fish is taken out of water the gill flaments collapse.  Look at a perosn with striaght hair when they climbs out of the water and notice how the hair all sticks together in a sheet? The gills of a fish behave the same way. On dry land the gill filamens of the fish all stik togather. Instead of being able to extract oxygen from each one it can only extract oygen form the ones in the surface layer. That just can't provide the fish with enough oxygen and it suffocates.\n\nContrary to popular belive fish don't technically die because they can only extract oxygen form water. Fish could breath air just fine if the gill filaments didn't collapse. \n\nIOW fsh die on land because air can't support their bodies the way that water can.

"Osmoregulation is the control of the levels of water and mineral salts in the blood"\n\nTherefore I say why not in fish?  They have blood and their blood also needs to have it levels regulated so it makes perfect sense. If you do not believe me here ya go :D\n\nWithout osmoregulation fish will die \n\nOsmoregulation is the control of the concentration of body fluids. If a fish is unable to regulate the effects of osmosis it will die. Clearly, osmoregulation is a vital function affecting all aspects of fish health.\n\nOsmosis, diffusion and fish health\n\nIf we look at the structure of the gill or gut under a powerful microscope we would see the tissue that lines these structures, the epithelium, is very thin, usually only one cell thick. Such areas are rich in blood vessels with very thin walls. The combined thickness of epithelium and blood vessels is less than the size of a full stop. The structure and thinness of these areas means that the minute particles whizzing around in the water (and blood) can pass through the epithelium and blood vessels with relative ease; in fact in many cases it is as if there wasn't any barrier at all!

Unfortunately this is a sign of disease in fish. It usually comes before their death. You could try an antibacterial remedy.

Check with the local wildlife service in MN. They can tell exactly why the fish are dying and if you should be concerned.

OK a'lot of u don't no anything about catfish! It just depends on what catfish your dealing with and the conditions.  Some catfish in Africa can survive months without water, walking catfish have the capability of breathing oxygen (Bowfin are like this as well) they have something like a lung and this lung has chambers capable of taking in oxygen.  But these fish still need water in order to survive. I was fishing and caught these bullheads (small catfish) we accidently forgot one and this was in the afternoon when I returned the following day around 5-6pm it was still breathing I placed it back into the water and swimmed away.  CONDITIONS: The ground has to be moist or wet/muddy (keeps them cool) and theres a small amount of oxygen in the rain drops, moist ground, or mud.  If it's sunny and hot these fish wont live long (due to the slime drying out) and the slime makes them swim fast/quicker, scent (to find mates), and protects from diseases/viruses.
