I was considering stocking CB Hybrids and found a hatchery down south who had them...I could have sworn they advertise in PB backpages.
I do know they grow upward of 30-40 lbs - very fast growing - but was discouraged to stock them because of their: 1. impact on the forage base 2. reportedly hookshy after being caught once or twice
I think the hatchery was in MS.
I have a thread somewhere in the archives RE CB Hybrids...
