QA,
I feel wholly inadequate on the aeration questions but I would like to give you something to think about that may help with DO.
In addition to thinning the crayfish as needed, consider adding some additional shredder type forage. Hyalella Azteca and PK shrimp. Beyond the forage, I think they would help to keep your water clearer. They will be more abundant if you continue thinning crayfish and they may actually inhibit some of the crayfish foraging activity in the sediment in that they are also crayfish prey. Having clearer water will help your DO and these shredders will help to reduce the amount of decaying matter returning the nutrients to solution. Deeper sunlight penetration will boost photosynthesis and water clarity will help predators find prey and home in on your fishing lures. Both the fishing and DO should improve by reducing turbidity.
