Fishmongers are people who sell fish for people to eat. Just like how you can go to a store to buy toys or clothes, you can also go to a store to buy fish. The fishmonger is the person who works in that store and helps you pick out the fish you want to buy.
The fishmonger knows a lot about fish, like what fish are good to eat and how to prepare them. They can tell you about the different types of fish like salmon, cod, and tuna, and how to cook them in a yummy way. They can also tell you if the fish is fresh or not.
When you go to buy fish, the fishmonger will show you all the different types of fish they have for sale. You can tell them which fish you want and how much you want. They will then weigh the fish and put it in a bag for you to take home.
So, fishmongers are like special fish salespeople who help you pick out the fish you want and tell you how to cook it. They make buying fish easy and fun!
