A sea fish can’t live within freshwater as the natural process of diffusion acts against them, while their bodies have already adapted to living in the ocean. “The fish that are found in freshwater are not the same fish as those that live in saltwater,” .

What happens to a saltwater fish if you put it in freshwater?
A saltwater fish in fresh water is more salty than its surroundings. The surrounding water flows into their cells and they begin to swell. This process is known as “salting” and is a natural part of the fish’s life cycle. However, in the past few decades, the amount of salt in freshwater fish has increased dramatically. As a result, fish that were once salt-tolerant are now more susceptible to disease and disease-causing bacteria.
Why can some fish live in freshwater some in salt water and some in both?
Their kidneys produce small volumes of fluid containing high concentrations of salt. The fish produce large volumes of urine which is low in salt. To maintain stable concentrations of blood salts in fresh water, less demand is placed on the kidneys. In freshwater fish, the concentration of sodium in the blood decreases with increasing salinity. This is called the “salt-balance” effect, and it is one of the most important factors in determining the salt content of a fish’s diet.
The salt balance effect is important because it determines how much fish a person can consume in a given period of time. It also determines the amount of fish that can be fed to an individual. For example, if salt levels are too high, it may be difficult for the body to absorb enough sodium from the diet to meet its needs.
Why can’t saltwater fish live in saltwater?
Seawater is hypertonic to the fish living in it, which means that the salt content of the surrounding water is higher than the content inside the fish. They lose the water inside their body due to a loss of buoyancy.
In the case of a fish, this can lead to an increase in the amount of salt in their blood. This can cause a condition known as hyponatremia, in which the body’s ability to absorb salt is impaired, leading to high blood pressure and heart failure.
Is it possible for a saltwater fish to thrive in a freshwater environment give examples of fishes that we can acclimate to water with a different salinity?
Most fish are sensitive to any changes in the levels of salt in the water in which they live. The stenohaline species include goldfish, which can live only in a narrow range of water salinities.
Goldfish are the most common fish in freshwater aquariums, but they can also be found in brackish, saltwater, and marine aquaria. They are also very tolerant of high nitrate and nitrite levels, as well as low pH and high ammonia levels.
Can clownfish survive in freshwater?
Clownfish are strictly saltwater (marine) fish, which means that these would not survive in freshwater. The clownfish lives near the reefs and is a reef-associated fish species. Coral reef fish are found in tropical and subtropical waters around the world, including the Caribbean, the Pacific, and the Indian Ocean.
Can you drink salt water to survive?
Humans can only make urine that is less salty. Even though you are still alive, you die of dehydration. The same thing happens when you eat salt-rich foods. When you take in too much salt, your body can’t make enough urine to replace it. This is why people who eat a lot of salt tend to have high blood pressure, high cholesterol, and other health problems.
How do fish live in both salt and freshwater?
Their kidneys are specially adapted to excrete lots of salt, and even their gills can excrete salt in this way so that they keep their blood salinity levels at an optimum. The most salt tolerant animals on the planet are freshwater fish. Salt is essential for the body to function properly, but it is also essential to the growth and development of the brain and nervous system.
It also plays an important role in the digestion of food and the absorption of nutrients from the food we eat. In addition, salt helps to regulate blood pressure and blood sugar levels, as well as keeping the heart healthy and pumping blood to all parts of our body.
