How long will my shellfish stock last for in the fridge?

Just made a shellfish stock today (Tues 28th) ready for a prawn bisque we were planning to have on New Year's Eve. Unfortunately without thinking I have included some fish stock from out of the freezer so I don't think I should re-freeze . Will the stock be ok in the fridge until New Year's Eve ?|||No. Throw it out and make fresh on New Year's Eve|||It is fine for 5-7 days, once it has cooled cover and place in the frig, bring to the boil and add to the mirepoix when making the bisque on NYE, what I do is buy shrimp shells, here in Toronto Canada as I was a chef at one time, I get lobster bodies, sometimes a few fish bone, and make my stock for soups, paellas and more, I freeze it in zipper top plastic bags even got some ice cube bags a few years back when visiting my chef mate in Liverpool, unlike poultry and beef stock, there is a very small amount of fat, seafood is not as fatty as meat broth is and that is what taints it and makes it go sour.|||Boil the stock with the added fish stock, cool then freeze. Fish stock should keep for 24 hours as long as it has been kept very hot or very cold.
