It is obvious that this subject is ver forign to most pond owners. We have not herd from any one who can give a real deffinative answer on why some people who have stocked have a low success rate while others seem to do OK.
The first time I went to a hatcher I ask the guy there what the main differance between blues and channels were...He first took me to where the channels were. He took a large dip net and scoop about a dozen channels. He pointed out how they were very dosicel and calm, saying these guys are not very aggresive, or not very nervous. Then we went to the Blues and he scoop up about the same number as the channels and it looked like water thrown on hot grease! They were flapping all over the place! He then said, "see how aggresive these guys are?" "They stress real easy.." So maybe there aggresive nature causes them to have problems in low water quality...
Well this is one of many thought on this problem
