Do fish have weight in water?
If the fish are neutrally buoyant (meaning their mass is equal to the mass of water they are displacing), then the tank would weigh the same as it did before the fish were added since the mass of the water we remove would equate to the mass of the fish added
Do you weigh the same underwater?
When objects are placed in water, their mass does not change They seem to feel lighter, though, because of buoyancy Archemedes’s principle states that the force pushing on an object under water, is equal to the mass of the water it has pushed out of the way
Is a fish denser than water?
Fish are slightly more dense than the water in which they swim They are almost neutrally buoyant, meaning the forces acting against the fish to make it sink are about equal to the forces inside the fish causing it to float It also means fish don’t have to work too hard to keep from floating or sinking
How do fish urinate?
Like you, fish have kidneys Kidneys help the body make urine The shape and size of kidneys can be different depending on the species A lot of fish get rid of the pee through an tiny opening, called a pore, that’s near their rear ends—and in some fish, waste also goes out through the skin or the gills
Do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest Research shows that fish may reduce their activity and metabolism while remaining alert to danger Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest
Are rocks lighter underwater?
When objects are placed in water, their mass does not change They seem to feel lighter, though, because of buoyancy So things apear lighter because the water is actually helping to push it up
How much does 10 pounds weigh underwater?
If Wa is a 10-pound rock above the water, it should weigh around 66 pounds when submerged underwater
Is gold lighter underwater?
It is very dense Another rather simple way to think of this is that if the density of water is 1 g/cc then the density of gold is 193 times greater than water Water weighs about 83 pounds per gallon Therefore gold weighs 193 times as much or (193 x 83 lb) about 160 pounds per gallon
Does weighing a fish hurt it?
Re: Weighing bass If you take your time you can easily get the hook between the last gill arch and the gill plate Just take your time and it causes absolutely no problems or harm
Do fish scales hurt fish?
Physical Damage When this happens, they brush up themselves to many objects present in the tank Thus, resulting in physical damage, that shows mostly in lost scales Another common cause for physical damage is the aggressive behavior of certain fish that are present in the tank
How many pounds does a fish weigh?
Example: A 30-inch striped bass weighs approximately 12 pounds (30″ x 30″ x 30″)/2,200 = 123 poundsHow Much Does Your Fish Weigh? Species of Fish Formula (see below) Striped Bass Length 3 2,200 Walleye Yellow Perch Length 3 2,700 Northern Pike Chain Pickerel Length 3 3,500 American Shad Hickory Shad Length x Length x Girth 1,650
Why do fish produce many eggs?
Rather, the rate of predation on fish eggs is high because they produce such a lot of eggs Many fish produce thousands of minute eggs, each with an infinitesimally small chance of survival because this reproductive strategy in these species results in the highest number surviving to adulthood
Can life exist if water sinks instead of floats when frozen?
Unlike plants, animals can move so they would move as far as possible or be trapped and frozen when the ice sank If ice did not float, life underwater would be impossible! Ice floats when water freezes on the top It stays on the top and ice slowly gets thicker, freezing our lakes and ponds from the top down
What does fizzing a fish mean?
Fizzing involves venting the excess gas from the swim bladder of a fish after it has been brought up from deep water, usually from a depth of 20 feet or more When a fish experiences barotrauma, it is unable to stay upright It floats on its side, and preventing it to swim back down once released
Can you drown a fish?
The simple answer: can fish drown? Yes, fish can ‘drown’–for lack of a better word Though, it is better to think of it as a form of suffocation where oxygen levels are too low or the fish isn’t able to properly pull oxygen from the water for one reason or another
Do fish ever fart?
Most fish do use air to inflate and deflate their bladder to maintain buoyancy which is expelled either through their mouth or gills which can be mistaken for a fart Point being – No farts
Do fish get thirsty?
The answer is still no; as they live in water they probably don’t take it in as a conscious response to seek out and drink water Thirst is usually defined as a need or desire to drink water It is unlikely that fish are responding to such a driving force
Do hooked fish feel pain?
DO FISH FEEL PAIN WHEN HOOKED? Catch-and-release fishing is seen as a harmless hobby thanks in part to the belief that fish do not experience pain, and so they do not suffer when a hook pierces their lips, jaws, or other body parts
Why don t fish have eyebrows?
Answer: Fish don’t have eyebrows because well, they live in water In fact only a few species of mammals have eyebrows Birds, amphibians, invertebrates, and reptiles also lack eyebrows
Do fish get bored?
Just like any other pet, fish can become bored, too And while they won’t chew up your shoes, keeping them occupied will ensure they live a healthier life Bettas particularly enjoy moving them around the tank, but just about any fish will be curious enough to check it out
How much can you lift under water?
So the density of water is about 127% of the density of iron, therefore, it reduces the apparent weight of iron by 127% If it takes, say, 100 newtons of force (about 225 pounds) to lift a particular iron weight on land, it would only take 873 newtons (196 pounds) to lift the same weight in freshwater
How much is 405 pounds underwater?
According to his math, one pound on land is actually 86 pounds in the water So 45 pounds is really 387 pounds in the water and 405 pounds is 3483 pounds
Is it easier to lift weights underwater?
Why is it easier to lift a heavy object when you’re in the water than on land? The answer lies in the scientific concept of buoyancy, and you can thank Archimedes for the explanation In fact, the water will push upward against the object with a force equal to the weight of the water it displaces
