Hi Jeff,
If using Frozen bait, take it out the night before and soak it in a brine mixture in order to firm the bait up, This will help it keeps it shape and shine as you fish with it.
If you bought dead herring, you could bring it home and brine it for use in the next day or so.
I would refrain from using anything that I wouldnt want to eat myself, so to speak. You know what I mean, if it looks like crap and smell like Shiot, the fish will turn his nose to it too.
For live bait you have to keep fresh cold water on them. I have seen beach fishers use those mesh diving bags to keep live bait in the water. The mesh bag allows excellent water flow and they cannot swim away. You could make your own device that suited the fish the same. If they die and are still fresh they should work fine.
I always like to get Fresh bait myself, But I dont always launch where there is good bait available. For this summer I have bought a 1/2 case of frozen Ballard bait this year that I can use as necessary. Their bait freezes alot better than some of the other local brands I have seen due to their packaging.
Any frozen bait with loose ice crystals within the packaging is not good bait IMO. It means some/all of the fluids have been extracted from the fish, so once it thaws it will be a little ugly herring biscut.
