  6. Water came out of ground around 7 ppm. After 2 nd section it was 5 ppm. LHO boxes bumped it up to 8 ppm. Went through two more sections and left 4 th section at 5 ppm to LHO’s. Bumped back up to 7 ppm and left bottom of raceways at 5 ppm. Great efficiencies transferring oxygen into 5 ppm water—up to 90%

  7. Quiescent zones, cleanout stand-pipes, demand feeders, LHO’s, and air-cleaning allowed us to double catchable production without increasing labor on 13 strains of fish
