I'm in a rod & gun club & we have a good stretch of water on the Muskenetcong river here in NJ. I'm putting together the gear & people to do a stream Macro-invertebrate study on the river. I gathered up a lot of info from the internet but I'm wondering if anyone of you people have done one, & can give me any advice. I'm looking for a cheap source of the necessary supplies, net & stuff. I'm also looking for a good source of insect I.D. information. If you have ever done one , what sampling protocol did you use etc.
