Not me - I have seen the results. A friend kept a 10 acre BG study pond for fisheries science teaching and research. After a few years his students reported back that their seining was resulting in fewer and fewer BG. So they drew down the lake and seined it. They were amazed to find few BG and about 12 large FH catfish from 50 to 10 lbs. The neighbor was raising his FH cats in my friends pond. \:o --
