shipposhack;110893 said:My experience with priority mail shipping and mysids is poor. 3/5 times that I order they arrive dead. I get stryo and a heatpack but they still don't do well. My guess is that it's the cold weather here. You also should get them out of the bag right when you get them because I have had a batch of shore shrimp that were fine upon arrival die 5 hours later because of the NO3 in the bag. I opened up the bag and floated it when I got them so they would have O2 and when I came home they were dead :/.
Animals die because the toxicity of the ammonia is held in check by the lower pH in the bag due to the co2 built up in the bag during transport. Once you open the bag and release the co2 the ammonia becomes rapidly toxic. Float the back to equalize the temp's but don't open it till you are ready to get them into their holding tank.
Utah shipping is hard. I lost a batch in transit due to the cold recently too.
