Seminar on Radioactive Fish
The Hatfield Marine Science Center’s Thursday research seminar series continues online. This week’s offering, at 3:30 p.m. on Thursday, Dec. 16, has the provocative title, “A Study of Radioactive Fish Ears or How I Learned to Stop Worrying and Love the Bomb.” The event is free and open to all.
The speaker is, no, not Dr. Strangelove, but rather Andi Stephens, a research fisheries biologist with NOAA’s Northwest Fisheries Science Center, located at the Hatfield Marine Science Center. Her description of her talk:
“Age validation has long been recognized as critical to the assessment process. It is analogous to calibrating scientific instruments. Imprecision occurs when multiple reads report different ages, and bias is a systematic under- or over-estimation; these are confounded in aging lab settings. Imprecision in terms of between-reader variability can be quantified and addressed, for example using age-error matrices in stock assessment models. Bias can only be uncovered by an age-validation study. I will discuss these issues and present several examples of recent work.”
