Michigan
Raceway UV a Success
Marquette State Fish Hatchery in Marquette, Michigan is a typical
cold water flow through trout hatchery. The hatchery employs
7 raceways for char brood stock and 10 raceways for char production
in serial reuse fashion.
The hatchery
has a long history of fish health problems in both the char
brood stock and production fish due to pathogens in its receiving
waters; specifically Aeromonus and Renibacterium. The state
solicited and WMT was the successful bidder to supply a UV
system capable of installing in the hatchery raceway to disinfect
the incoming water.
The UV
system is installed in a head raceway that serves the brood
stock raceways. Below are initial results of the raceway UV
system delivering 45,000 uWs/cm2 @ 3,000 GPM.
Emperor
Aquatics Inc. assisted WMT with the UV portion of this project.
