The impacts of PCB exposure on skeletal development, survivorship, and feeding ability in zebrafish
Research Mentor(s)
Dr. Jim Cooper
Description
Although their production has been banned for several decades, Polychlorinated-Biphenyls (PCBs) are widely present throughout the Salish Sea. These synthetic organic pollutants are known to cause a variety of adverse effects among fish species and other marine organisms as well as persist in marine environments for long periods of time. To better understand the implications that these toxins have on marine ecosystems, we are examining the effects of PCB toxicity on the development of zebrafish raised in the Cooper lab. Treatment groups were exposed during the embryonic stage to different concentrations of Aroclor 1254, and mortality, feeding success, and skeletal development are being monitored over the course of approximately thirty days. Through this study, we hope to gain valuable insight as to the impacts that these toxins have on morphology, development, and survivorship of zebrafish and use those findings to further studies on PCB effects on forage fish in the Salish Sea.
