That 1.5 hr one way ride from the G to Bham is definitely going to put a ton of stress on those fish. Survival rate would be much higher if they just released them in the river there in bham versus hauling them all the way back to the G to release. Just not a good option IMO. Hot water, low oxygen/inadequate aeration, and stress are the three biggest killers of released fish. First two are easily remedied with insulated live wells, ice and good equipment, on the third all you can do is do your best to minimize it.
