Ok, I took a photo of the 4 GSF and thier stomache contents. They were caught by line & hook in the area of the feeder about 30 minutes after the feeder went off. 3 of the 4 stomaches were filled with what looked like soft AM. The fourth one was empty.
This is a HSB I caught this morning on a worm & brim hook. He is 10.5" long and weight was 8 oz. I put him in the pond late May when he/she was 3". We released a total of 18.
