Not sure what HD is saying, these fish go up river to mostly unsuccessfully spawn then die.
It is a 'put and take' fishery of non- native species.
I go up to Upper Credit a few times a year to get away from the lower trib madness. There is WAY more fish and WAY less fishermen than what you posted, also no kill, barbless, no bait etc, conservation... in the miles upon miles of river with nary another fisherman.
But whatever, the main thing is you had fun fishing with your daughter.
