Currently there is no settling in the system except for the end of the raceways, where we have a 1 meter long section before a top mounted weir.  This is insufficient.  We are currently trying to find a remedy that fits our system.

I'm guessing you ment shrimp.  While we have a crayfish species here that will tolerate 12-16 C water, I do not know of any commercial shrimp that will work.  Especially when you ask the Department of Nautral Resources about bringing in a nonnative shrimp.  The problem with crayfish is that they tend to lop off all the roots from the tray down.
