We are starting to get more organised with our aquatic invertebrate studies on the Cod Beck. We had school parties from Bradford and Wakefield do a day study this summer (see Schools visit) and the results were quite interesting. Essentially we have a higher biotic index above the sewage works than below. Although, please note, this is a preliminary finding and much more work needs to be done.
We are indebted to Alastair Logan who has spend most of this summer sampling the Cod Beck in various regions. Currently he has been cataloging and photographing his results. If you would like to see what nymphs and adults he has found in the Cod Beck please look at the four slide shows below. They may give you some ideas in selecting flies to fish the Cod Beck with.
They have been divided into Nymphs, Adult upwing flies, Caddis and Stoneflies. Most of the stoneflies were found above our stretch of the Cod Beck, although I have found a few nymphs opposite Thirsk Swimming pool. Everything else was sampled or photographed on our stretch of the Cod Beck
