As part of the ongoing Research Seminars series, the Hatfield Marine Science Center (HMSC) will host Ken Zillig, a Postdoctoral Researcher in the Fish Physiology Lab at the University of California, Davis, to discuss his work on conservation physiology of anadromous West Coast fish. This presentation will take place on Thursday, Dec. 1, at 3:30 p.m.

About the talk:

“The application of physiological techniques to inform the management and conservation of fish species is a developing field. I used ecophysiological techniques (metabolism, CT_MAX, growth) to investigate the thermal performance of eight populations of Chinook salmon (Oncorhynchus tshawytscha) juveniles and investigate patterns of local adaptation and interpopulation variation. We identified environmental drivers associated with population differences which support local adaptation among Chinook salmon populations. In a separate study we investigated the effect of feed rationing on the metabolism of green sturgeon (Acipenser medirostris), a species sympatric with the critically endangered winter-run Chinook salmon. Our results support a conservation conflict between these two endangered species and highlight the challenge for setting thermal regulations for an ecosystem.”

These talks are delivered in a hybrid fashion. The event is free, and all are welcome to attend in person in the auditorium of the Gladys Valley Marine Studies Building at the HMSC (2030 S.E. Marine Science Dr).  You can also attend online. Register here to attend remotely via Zoom.
