I'm in a rod & gun club that has about 2 miles of one of the best trout streams in NJ. We had a lot of stream work done last year & I'm putting together a plan to do an invertebrate study on the river. I went on the web & came up with the basic protocols, but I'm looking for any further info. Over the years I've picked up some knowledge of stream insects. but not for all the bugs I expect to find. Besides "Trout Nut" can you recomend any sites that will aid me in bug I.D.'s.
