We bought our Missouri property 2 years ago and it has two ponds. One is 1/3 acre the other is 1/4 acre. The water seems to be in good shape and has American pondweed around the shoreline. The 1/3 acre pond was stocked with CC and BG. The 1/4 acre pond has BG. I have caught a lot of nice CC from the 1/3 acre pond that are around 24". Also there are a lot of small 3"-6" CC so I know they are breeding. I think the large CC are eating all the BG in the pond. Years ago they ran some cattle on the property. So I have two questions. The first one is should I remove the large CC from the pond (I will eventually stock a few LMB)? The second is can I send the fish somewhere to determine if they are safe to eat (will a water sample tell me that)?
