How does the milk color in fish soup come about

The key to milky fish soup is frying it, and frying it at a high enough temperature. To find out why, the milky color is due to the fish skin. When I was a kid, I used to make jelly with fish gelatin powder, which is white in color, and the fish skin does contain a lot of fish gelatin, so the milky white color of the soup is due to the fish gelatin. I guess the fish skin is easier to dissolve after frying. Therefore, if the fish is not fried, the soup is not white; if the small fry, fish glue dissolved need to cook for a long time; if the fire fry, fish glue is easy to dissolve, a little cooking that is white.
