Fish Housing System

Description:

Background

One persistent challenge of fish husbandry is how to capture fish that escape from their tanks and prevent them from entering the local sewer system or contaminating the recirculating water supply.  Researchers at the University of Oregon developed a novel device that solves this problem.

Catching escaped fish upstream in the system reduces the risk of potential health hazards to the fish colony through contaminated water supply and prevents the escape of these fish to the wild via sewage discharge, a concern with transgenic animals, as stated by the USDA and NIH guidelines. Furthermore, regulations on the use of aquatic animals are becoming more prevalent, as evidenced by recent changes to the Guide to the Care and Use of Laboratory Animals, the standard for laboratory vertebrate animal care in the United States. Therefore, efficient containment and humane treatment of escaped fish could become necessary for AALAC and other types of accreditation of research facilities, which could impact their ability to obtain government funding.

 

Technology summary

The UO Fish Trap has a modular design that allows it to be installed or retrofitted into a variety of commercially available fish tank systems.  The trap is placed in line with the tank system’s main drainage pipes, catching escaped fish well before they reach the system’s sump. Because the trap is transparent, escaped fish are easily detected and removed while they are still alive.  The fish trap is about 3 feet long with 3” couplers at each end.
