A similar question came up somewhere else...seems it was discussed that either tadpoles are toxic to fish or they just dont taste that good. We have two primary frogs here (tree frog and bull frog) the tree fog tadpoles had their heyday in the spring/early summer, now 1,000's of big (up to 3-inch) bullfrog tadpoles actually school around, and are having their heyday right now in mid-summer. Like Theo said, must mean you have a healthy pond....i've heard amphibians are like the coal mine canary for environmental problems......in my case, i like having so many of them esp. right now, because the egrets, herons, and kingfishers are concentrating on them instead of my young fish.
