That there are alot of varibles on how long they will live such as how they are hooked and how they are unhooked and handled, water temp, size of bait tank, amount of bait in your bait tank, types of bait you have in your tank...There really isn't a solid answer to the amount of time sardines should last...With that said it also wouldn't be unusual to have your bait last all day.

One thing is for sure...if you catch herring which closely resemble sardines...they will not last more than a few minutes and die right away in your tank. If your having problems with losing a good chunk of your bait, next time take a look at the dead ones...they might be those pesky herring. I usually throw those back as soon as I catch them.
