Yes, as a fish moves ,from saltwater to freshwater, the concentrations of salt ions drops as freshwater enters the body via osmotic pressure.

Does salt water conduct more electricity than fresh water?
salt water conducts more electricity than fresh water because it contains great amounts of ions which can conduct a lot of electricity
Why is salt water a better conducter than fresh water?
The salt separates into ions, and those will carry the current.
Does salt water conducted electricity better than fresh water?
Because salt water contain ions of sodium and chlorine.
How do you ingest iodine?
White fish , e.g. cod, hake, haddock etc., , when eaten will maintain your iodine levels. NB White Fish from the sea absorb, iodide ions, which present in salt water. Then by eating white fish the iodide ions are transmitted into the human organism. Sea Water, not only contains salt (sodium chloride) , but many other ions , iodide ions included, but in smaller quantities. Crustacea(crabs), and oily fish( mackeral) have less iodide ions .
How do banana peels generate electricity?
Bananas have a lot of water in them. The water has various ions including potassium, sodium, calcium, chloride... Electricity moves through water because of the electrolytes mentioned and other ions. The more salt in the water, the better it conducts electricity.
The process thaty causes water to flow into contractile vacuoles?
in fresh water the concentration of solute (particles and ions in water) is lower than that inside the cell. through the process of osmosis, water moves into the cell to equalize the concentration. the water must then be pumped out, so that the cell doesn't burst. in salt water there is less or no difference in solute concentrations inside and outside the cell, and no need to pump water out.
What moves water and minerals through a plant?
transpirational pull and the roots actively take up ions from the soil, this creates a difference in the concentration of ions; to eliminate this difference water flows into the roots and is transportd to the rest of the plant body.
How are fish in fresh water affected by osmosis?
swallow plenty of sea water to increase amount of water in the body have chloride secretory cells in their gills to remove excess salts few glomeruli thus slow filtration rate in the kidneys eliminate nitrogenous wastes in form of trimethylamine oxide which requires little water for elimination.
Which type of water conducts electricity salt water or fresh water?
Both conduct electricity well, however salt water is a better conductor due to ions available.
What is one way a saltwater fish controls the concentration of salt in its body?
Some fish balance water loss by drinking seawater and actively transporting chloride ions out through their skin and gills then the sodium ions follow passively out as well.
What process is water moving out of the cell of a saltwater fish and into the ocean?
Diffusion is the way water moves out of the saltwater fish and into the ocean.Fish and aquatic animals have a complex task of Osmoregulation. Their bodies and especially the gills are bathed in either salt water with high salt levels for sea life, or freshwater with low salt levels for freshwater fish.The saltwater fish tend to keep saltier blood than freshwater fish. In some species, it essentially matches the environment.In the sea, some animals maintain essentially an isotonic solution between the blood and the salt water thus preventing osmosis into the ocean.Other ocean fish drink salt water, and actively pump sodium and chloride ions out of their gills to maintain the osmotic gradient.Freshwater fish have highly efficient kidneys to excrete lots of water and little salt. However, they still must expend energy to pump salt and ions into their bodies.Here is an excellent summary article:http://www2.hawaii.edu/~delbeek/delb11.html
How does a water conditioner work?
It exchanges 2 ions of salt for every ion of hardness (calcium and magnesium). When the salt is exhausted, a backwash occurs that flushes the hardness ions to waste, replenishes the bed with fresh salt ions and starts all over again.
