You'll need to pack the fish in a small thick-walled styrofoam shipping
container nestled within a cardboard box filled with packing peanuts. It
is essential to pack the styrofoam peanut layer with a few heat packs-
the kind used as hand-warmers for cold-weather sports will do. If the
fish are going really long-distance you may have to invest in heat packs
that are specifically designed for shipping livestock and maintain heat
for a longer duration. You can find these at aquabid.com.
p.s. make sure the heat packs do not come into direct contact with the
container holding the fish...ironically, direct contact with the heat
packs could fry your fish even if the outside temperature is frigid.
