The salted fish showed that a person wanted it but didn't receive the message.

What you want to ask is the reason why salted fish shows that a person wants it but doesn't receive the news. The buyer did not send a message to the seller. Idle fish want means that someone clicks "I want" in the lower right corner, indicating that they want to buy it. If they don't buy it, they just keep it for the time being. If they don't communicate with the seller, they won't receive the news.
