SideRack: A Cost-Effective Addition to Commercial Zebrafish Housing Systems

Commercially available aquatic housing systems provide excellent and relatively trouble-free hardware for rearing and housing juvenile as well as adult zebrafish. However, the cost of such systems is quite high and potentially prohibitive for smaller educational and research institutions. The need for tank space prompted us to experiment with various additions to our existing Aquaneering system. We also noted that high water exchange rates typical in commercial systems are suboptimal for quick growth of juvenile fish. We devised a housing system we call “SideRack,” which contains 20 large tanks with air supply and slow water circulation. It enables cost-effective expansion of existing fish facility, with a key additional benefit of increased growth and maturation rates of juvenile fish.
