This has been an extremely valuable thread, and I learned several important lessons from this outstanding thread. The most valuable of these is that I won't ever electroshock fish myself and, if I were staying in the pond world, I would continue to have it professionally done, as I have in the past.

A related question is that I once had the pond electrofished by a reputable private company and had it sampled by seining by the state fishery folks in the same year. The results were not even similar. The sein showed a pond in balance. The electrofishing showed a pond very much in imabalance, with more bass than bluegill! I decided, based on what I was catching (many small bass, moderate numbers of very large bream and very small ones, and almost no bluegill in the intermediate range, that the electrofishing results were more reliable. Is this generally true?
Thanks,
Lou
