This looks like a great project. I would love to hear more about it. Also I am beginning a masters project at The University of Montana with a focus on the invasive aquatic species, New Zealand mudsnails. I am using underwater videography to determine changes in foraging habits, if any, in salmonids in the the presence of the invader. I would love to hear more about the effectiveness of the different cameras you have used as I am currently looking for the right setup for my project.
Thanks,
you can contact me via email…
