There are currently two zebrafish facilities at Ohio State University
The first facility located in Bevis Hall was built in 1998. This facility houses ~1200 tanks and ~30,000 fish at capacity. This is a Pentair Aquatic Habitats system (http://pentairaes.com/aquatic-habitats)
The second facility located in Rightmire Hall was built in 2012. This facility houses ~1800 tanks and ~45,000 fish at capacity. This is an Aquaneering system (http://www.aquaneering.com/)
There are three labs at Ohio State that use zebrafish as their main model system:
Beattie Lab
Amacher Lab (https://molgen.osu.edu/amacher)
Jontes Lab (http://medicine.osu.edu/neuroscience/people/faculty/james-d-jontes-ph-d/Pages/index.aspx)
The Beattie and Jontes labs use the Bevis facility and the Amacher lab uses the Rightmire facility
