There has not been much change in the aquatic vegetation since I stocked the Grass Carp following state wildlife recommendations per acre (15 TGC 60 total). Till they died off the bottom was bare. I only stock 6-10 total as needed now & I am happy with the weed control. I have not noticed any change after stocking the TP. The murky green color & much reduced visibility is something new the past few years. It is very interesting how the pond & populations have changed. Bowfin & Brown Cats have been removed or under control. My thoughts that this summer would be one to remove as many remaining Cats as I could. Although, I have not seen a black ball of just hatched catfish near a bank in years. In the beginning it was a routine thing to see in the spring. Thank you for your thoughts.
