Crawdaddies
So far in our experiment we have found that more crayfish are found in pools than riffles or runs. We have found a total of 7 caryfish in pools, 6 in runs, and 0 in riffles. When you look for crayfish you should start down stream and go up, instead of starting up stream and going down stream, this way, you end up catching the maximum number of crayfish possible. If you start up stream dirt will travel down stream disturbing the crayfish and then the crayfish will leave. Then your data won't be as accurate as it could be.

Why does it make a difference if you start up stream rather then starting down stream? Also, what types of macroinvertebrates did you catch in the pool and run? THank you for your time. ~~Susie Q.
