Making fish broth without fish bones?

As a one shot deal, I want to make a fish broth without the hassle of fish and fish bones. I have chicken and vegetable broth already. Thinking of adding some claim juice. No dashi suggestions, please. Any other ideas of what to put in it without adding too much salt? Thanks.Making fish broth without fish bones?

Broth is made with meat and vegetables and water



Stock is made with bones and vegetables and often meat, but not always



You can make fish broth without bones, but you can't technically make it wihtout fish meat.



Is there such a thing as seafood bouillin? You may be able to get a seafood base a some gourmet markets.
