Guys, I appreciate the responses. I have not done a jar/bucket test although I do plan on doing on beginning this afternoon. I myself did not believe crawfish would churn up enough mud to discolor the water in a 1 acre pond. We shall see. I have also spoken with LSU Ag and they aren't exactly sold on the catfish being the main culprit either. The biologist I spoke with said there are many ponds with a combo of LMB and Catfish and the water is clear. Like what most of you guys are responding, it may be a trail and error kind of thing in order to get the pond where I want it.
