Here's a breakdown:
* Milt is a general term for the sperm-containing fluid of male fish.
* Salmon milt specifically refers to the sperm of male salmon.
* It's a whitish, milky fluid that is released by the male salmon during spawning.
* The milt fertilizes the eggs released by the female salmon.
Salmon milt is used in some cultures as a food source, particularly in Japan where it's known as "shirako." It is also sometimes used in some traditional medicines.
However, it's important to note that eating raw salmon milt can carry a risk of parasites and bacteria. It's generally recommended to consume it cooked or processed.
