There used to be, but not really any more. Some 'fining' agents used for clearing beer or wine are made from fish parts (called isinglass), but that is not a common fining agent anymore. Usually brewers filter instead of fine, or they use carageenan, or "irish moss", which is from seaweed. Occasionally they use gelatin, which isn't a vegetarian product, but that isn't very popular these days either.

If you drink microbrews, you can ask the brewer yourself, you'll find most don't use animal-based fining agents anymore.

What were we talking about, anyway?

Peace,
