| Notes | Can fish inherit vulnerability to hook-and-line angling? This abstract describes an interesting experiment aimed at answering that question. In 2015 and 2016, Alsea River steelhead were captured by two methods: fish traps and hook-and-line angling. “Each female was spawned with a single male that had been collected in the same manner, and we sampled tissue from all fish spawned.” (p.68) In the winter of 2017/2018, the next generation of steelhead were caught by both methods, and fish were sampled to see if they descended from fish previously caught by the same method. There was a slightly higher percentage of fish descended from parents caught by hook-and-line that were themselves caught by the same method, as opposed to fish caught in fish traps. This difference was not statistically significant. “suggesting little influence from the source of parents over the vulnerability to angling of their offspring.” (p.68) |
