By the way... I pulled two more dead fish out of the cage tonight.... hope this doesn't continue!
If I was you and I lost a few more I still wouldn't be that concerned. After the seining, handling by the grower and then again by the retailer if he is different, and then transport it's not unusual to lose a few fish. It's just a very stressful situation for them. If they are feeding that is a good sign. If we stay cold for a while and newly purchased fish don't want to feed that is when you will lose a fair number to fungus. The best scenario for stocking a pond (or cage) is when water temps are rising. Unfortunately of course we can't control the weather.
What part of the state are you in Spark plug?
