ABSTRACT

ABSTRACT In 2008, Fluid Imaging Technologies adapted their imaging particle analyzer, FlowCAM, used to detect and identify zebra and quagga mussel veligers-offering aversion of FlowCAM, equipped with cross-polarizing optical ‘lters for the purpose of detecting the natural birefringence seen on veligers.Anumber of organizations in the Western United States have since been using FlowCAM to monitor veliger activities. Included is the Bureau of Reclamation (BOR), who recently entered into a Cooperative Research and Development Agreement (CRADA) with Fluid Imaging Technologies to furtherenhance the technology for the express purpose of detecting, identifying, and enumerating dreissenid veligers using adual camera approach. With input from BOR, engineers at Fluid Imaging Technologies have taken proven FlowCAM technology and improved its ability to detect and identify veligers, while increasing sample volume processing capability.
