Ditto on the water temperature was a wee bit too high. Whenever I haul HSB, I use salted water, more so than for regular pond fish, make sure the O2 is going good and don't put more than a few in the net when moving from tank to bucket.
HSB, Golden Shiners and Crappie are very touchy fish to transport. BG/RES are "Goldilocks" fish. Not too hot, not too cold.
Ideally you want water temps to be in the mid to low 60's but then again water temp in the ponds shouldn't be more than 5°F different and not more than 3°F different is ideal. You can't change water temp more than 10°F in 15 min, and then you have to wait 20-30 minutes before changing the temp any more.
