faw,

We've had some bad experiences with grass carp in public waterways of Texas. In Lake Conroe, a prime lunker LMB fishery north of Houston, grass carp were heavily stocked to get rid of hydrilla...well in the process, they "denuded" the entire lake and as a result, recruitment dropped and LMB fishing suffered tremendously.

They have also been verified to be reproducing in the Trinity river...tripolid or not, some have escaped to that river and are reproducing. The problem they cause, IMO, is the complete elimination of vegetation...some vegetation is needed.

We had an interesting post several months ago, started by Norm, I think, in which several folks discussed the various state regulations. It was very interesting and almost came down to the old red state, blue state thing...i.e., states like Texas allow individual freedoms and accountablity in ponds whereas other states are very strict and exact complete Government control over pond activities. I think I remember correctly, that Bz in Mn. could not even catch what he wanted, when he wanted and in the numbers he wanted in his own pond....had to adhere to state regs. The differences were simply amazing from state to state.
