Fish stock - alternative?

[SmileAndNod]

I was going to make a salmon and leek risotto but on looking at the recipe you need fish stock. I have chicken or vegetable (cubes). Could I use either of these, or should I really go and buy fish stock? Other ingredients are smoked salmon, cream cheese and leeks if that helps. Though, tbf, the children will probably turn their noses up anyway!

I would use either cube. My preference would be the chicken stock because some vegetable stocks have a stronger flavour.

I would use the vegetable stock

Thank you. Think I have practically every other type of stock in the cupboard. I think I will go for the chicken, I think our veg stock is quite strong.
