Fresh Mysis Relicta Shrimp

[Delphinus]

I have a few questions ...

How many bags (of say the Piscine Energetics equivalent) is 5 lbs.? I forget offhand the bag size that I use... 8 oz. bag maybe? (I have no idea how many oz. in a lb.? I grew up in the metric age!) I'm taking a wild guess that there are 16 oz. in a lb., which would mean that 5 lbs. is 10 bags?

How do you ship it if it's frozen, such that it won't spoil while in transit? (Is overnighting it adequate?)

And ... this last one is just for my own curiousity ... what lake is it?? :D

Thanks
