You have trout that lasted 72F for a week? Amazing! I have a pond that all the trout die in one day with 70 F. Customer knows this and we are working on a solution to recirc the water and shade it. Also might try a different variety, but getting fish into Cal is getting tough.
BG are prolific spawners, and I cannot fathom how would they stress not having nests, let alone how they could not make nests. I had a pond with 3 feet of muck and just two adults and it was loaded with babies. I have another pond now where the bg are practically the last fish standing after a die off. I am sorry, but I am not buying the stress thoery.
