Thanks again for the continued food for thought.

Here is a neet little tidbit about sticklebacks in the Seattle area: http://news.nationalgeographic.com/news/2008/05/080520-fish-evolution_2.html

I did not realize that they could carry tape worms. According to the sources I could find, the tape worms are not the same kind as infect humans, however, I would not want to potentially infect my friends small pond fish population with any kind of parasite.

Mottled sculpin are found on his property, living in the stream. They are fairly abundant, and would be easy to transfer a few to the pond. Perhaps adding much more rocky areas on the bottom would help them survive.

Where do you know GSH are found? I don't think I will collect any, but I am curious if I am familiar with the same BOW with the good bass populations.
