Fresh fish typically contains a small amount of natural salt, averaging around 0.1 to 0.5 grams of sodium per 100 grams of fish. The sodium content can vary depending on the species and the fish's diet and habitat. It's important to note that this is much lower than the sodium content found in processed or cured fish. Cooking or seasoning methods can significantly increase the overall salt content in a dish.
If the salt water fish were to be put in fresh water then their high salt content inside their bodies (to prevent too much salt diffusing into their bodies) will have it diffusing out down the concentration gradient; killing them. If the fresh water fish were to be put in salt water then their low salt content inside their bodies (to prevent too much salt diffusing out of their bodies) will have it diffusing in again down the concentration gradient; killing them.
