Mattmonster, No we do not catch them like crazy. It is more like they are a bonus fish. We have had this pond 10 years and nothing has changed as far as the BCP population. We fish for them but usually catch them when fishing for something else. If we catch 3 or 4 in a day that is good. They are fat and healthy. We have hired pond guys to help but still the same. The BG and LMB have no problem and are also very fat. We may be lite on the zooplankton but I'm not sure. Maybe whatever it is it is a good thing. I have run several water quality tests and they say it is excellent.
