Floating herring question.

[MrHunters]

Sorry to have such a noob question but this is my first year fishing from shore.
I've had some luck with dead stinky herring so far this year. So heres my question. After a while it seems it just sinks and ends up on the bottom where by all accounts looks dead. Is there any ways other than finding a stronger current to keep the little bugger floating??
I can only assume it would be more successful that way.

Thanks guys.
