how much salt is in fresh fish?

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.
