Can sturgeon lie dormant for years in the mud until the river overflows and frees them?

Like you, I found no indication that sturgeon can go dormant in that way.  They do become inactive on the bottom when the temperature is cold enough.  If it was a report from somewhere farther south, I would have guessed the farmer found a lungfish, which does become dormant for long periods and can be solidly locked in dried earth without drying up, due to a nasty mucous cocoon they exude around themselves.  No lungfish are native to BC, though.

yes, there's a lot of money in raising both food fish (like tilapia & sturgeon) & ornamental fish. Your best source of info on this would be your county's extension offices. I'm attaching a link to UF's publications on aquaclture that I've found to be very useful.\n\nGood Luck!

it depends on the wetwater difilmater.

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!!!!!!!!!!!!!!!!

Water is a much more stable environment than living up in the wind and snow on land.\n\nIn freshwater systems, the water beneath the ice on lakes and rivers doesn't drop below about 4 C (around 40 F).  If it gets colder than that, the water freezes, and floats up to the surface to become part of the ice cover.\n\nSo the cold-blooded fish living in the water get their metabolism lowered by the cold temperatures, but they can still survive - even eating and swimming about (just ask any ice-fisherman).\n\nIf a lake or river freezes right to the bottom though, the fish don't survive.  They get frozen, and new fish either have to repopulate the area the next summer, or the water body remains fish free.\n\nThere are some fish (especially in Arctic waters) that produce anti-freeze like compounds in their blood to keep them from freezing solid.  In salt water, the water temperatures can drop below the freezing point of the blood in a bony fish.  Without these compounds, the fish would indeed freeze.  \n\nIn particularly cold waters, the fish hover almost motionless, their metabolisms so low that they are almost dormant.  Any sudden sharp jostle or even brushing against an icy outcrop can provide a nucleation site for ice crystals to form, and the fish can freeze solid in an instant.  I've seen videos of this happening, and its kind of freaky.

As far as I know, the Giant Mekong Catfish mentioned already holds the current record for largest living fresh water fish.\n\nOther giants of the fresh water realm include the South American giant arapaima (Arapaima gigas), or pirarucu.  There used to be specimens of this giant fish up to 15 feet long and several hundred kilos in weight, but they have been fished out, and individuals over 8 feet in length are very rare now.\n\nThe beluga sturgeon (Huso huso) of Russia at one time may have outweighed even the Mekong catfish.  Archaeological excavations of fish caught in the 14th century show that as many as one fifth of the beluga sturgeon caught back then were between 4 and 6 meters in length (12 to 18 feet).  The largest catch recorded was an individual 6 meters long and 3200 kg (7000 lbs).  Other evidence indicates that historically, this species could actually reach 10 meters (30 feet) in length!  Sadly, overfishing and other factors have reduced the numbers and average size of this slow-growing fish, and most of them now only reach 2 meters or less in size.

Brine shrimp eggs go dormant when dry. They are salt water crustaceans that are not found in oceans, but exist in deserts. They will last for up to ten years until the conditions are right for them to start developing. http://www.lawrencehallofscience.org/foss/fossweb/teachers/materials/plantanimal/brineshrimp.html

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.

Hi,\nI dont think so... Ducks are amphibians (I think). That means they can live both on land and water. But they are primarily land creatures. I mean they cant go swimming forever can they?\nDucks can be found on small lakes too. Not neccessarily marshes.\nNo, I dont think all rivers have marshes. There is a river here in our town. It doesnt have marshes...

river bank ? .. hmm.. maybe their gills... am i smart or am i smart..!! BWHAHAHAH

Water boarding wouldn't work.  You'd need to pull the fish out of the water and make it think it was dying that way.  Then they'd talk.  We have no choice but to use that technique, because some fish somewhere knows the details of a plot to explode a nuclear weapon on US soil.

I USED to go to the RIVER and I noticed that during the WINTER, when the Hydo-electric Establishment let the river down, so's people could fix-up their piers, the bushe's that used to be under the river water would start growing.  Interesting, cause all most of SPRING and SUMMER, they were under the water!!!!  Just something to think about, can't explain how they stayed alive, take a Botanist I guess!!!! Hope this helps........

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.

A mature White-tail stays in thick cover. Thats why they survive to be mature and big...they are much wiser. Look for them during the peak of the rut. Thats probably your only chance to harvest a big buck. After the rut they go into the cover again.

Yes they can. \n\nIt is happening in my beach house all the time. The house is closed all winter, when I go there at the begining of summer, the toilets are dry and I find frogs (usually dead because they are locked in the bathroom) on the floor next to the toilet.

'Several'; I don't think proper studies have been made on that :-) They usually stay around the pond where they incubated, but don't hesitate to fly a few kilometres around it to feed.

Some can lay dormant for alot of years until a fire comes through the area and scarifies the seed coat.
