You are “preaching to the choir” on the issue of using live bait. I also lived in Arizona, and fished live shad, bluegills, crawdads and other baits. But, we now live in Utah. Had to set my watch back 50 years when I moved back here.
There has always been a concern about chubs and other invasive species crowding out the hatchery pet rainbows. But, with the increasing introduction of piscivorous and sterile hybrids like tiger trout, tiger muskies and wipers, controlling chubs is no longer the problem it used to be.
**Oh yeah, Utah is one of only a couple or three states that outlaw the use of corn too…even for carp, where no trout exist. If you haven’t been exposed to that issue you wouldn’t believe all of the “REASONS” why we can’t use corn. Some of the explanations border on “Twilight Zone”. **
But, DWR is “trying” (very trying sometimes). They are very progressive for the 18th century. Much more reactive than proactive. And, once they react it is likely to be too little too late. With the RAC process it takes about 3 years to introduce an idea and get it through the process. By then a lake can crash or dry up and the new regulation is meaningless.
**I have good friends in Utah DWR, and I respect them for the jobs they do…often for less money than they could earn elsewhere. But, they are strangled by a stingy state government and a political heirarchy in the Division that makes it tough for knowledgeable biologists or COs to get anything accomplished. **
