Risotto and a complementing/contrasting broth corresponding to the meat
I have never seen a recipe for seafood risotto that used chicken broth. Commonly, clam juice or seafood stock is used. To me, chicken broth would clash. That seafood stock or clam juice is more common in seafood risotto recipes is confirmed by a Google search.

Personally, I would never use chicken broth to make seafood risotto. 

If I wanted a risotto to compliment seafood not actually in the risotto, I would also use a seafood based liquid.
