In March 2016 I put 100 4 inch perch in my one acre pond. Then for 17 months (Aug.2017) I never saw one pearch even though I feed my fish. Then I got this photo of a Great Blue Heron spearing this Perch. I was shocked at the size. The only fish I have in my pond are 5 grass carp & lots of Golden Shiners & Fatheads, frogs & turtles. Also the pond is full of Spatterdock that produces lots of bugs that feed my Red Wing Blackbirds. All I can think of is there is so much food that accelerate the growth of the Perch. After this photo the Heron flew to my floating island and swallow the Perch. I couldn't get my camera ready fast enough to get that picture.
