One thing I have found handy is a product called ammo lock 2 It dechlorinates water and renders ammonia harmless.. Very handy for shipping.
Actually ammo-lock simply keeps ammonia from rising above certain levels by binding with it. A better, and cheaper alternative is to put some zeolite (amrid) in the bottom of the bag.
A couple of tips from a very experienced fish shipper:
1. Fast all fish 24-36 hours prior to shipping....no food in the gut means no poop in the bag to foul the water.
2. Bag only with pristine water (doing daily 50% water changes for the three days prior to shipping will help with this).
3. Breather bags work, but must be fully filled (no air inside), and must not be touching each other or the sides of the shipping box (crumpled newspaper or packing 'peanuts' can work well as a buffer).
4. Ship only in a sturdy styrofoam box or cooler inside a sturdy cardboard box. Mark the outer box 'fragile', 'this side up', and 'keep between 10ºC-20ºC)'.
5. Pack fish in shipping-quality fish bags, and use pure oxygen whenever possible (many fish shops pack with pure oxygen).
6. Bags should be packed about slightly more than 1/3 water and slightly less than 2/3 oxygen, and never putt too many fish in a bag, especially large fish.
7. Pack with heat packs in cold (not cool) weather, and cold packs in hot (not warm) weather...in weather temps ranging from 8ºC-25ºC, hot and cold packs should not be required, if the fish are packed in a properly insulated box.
8. Ship in the morning or late at night on a Monday or Tuesday to avoid any delays caused by weekends.
9. Always ship the most direct, expeditious route.....under ideal conditions, fish can last 36 hours in regular bags (4-6 days in breather bags), but faster is always best.
