Citizen science is when members of the public directly work with scientists on a particular question or issue. Participation can range from a large number of single interactions to repeated and complex sampling that requires substantial training. A new paper now explains how to train participants, validate the collected data, and produce rigorous scientific papers from the outcomes. Key highlights include the need to increase the quality of data when designing a project, and to apply quality control afterwards to check for issues with the collected data.Read more

After a BS degree in Biology from Florida International University in 1979, I went to work for my father for six months while thinking about graduate school. UW came to my attention because it was rated in the top three aquaculture schools in the USA. I was pretty sure I wanted to be a marine biologist and thought aquaculture was the “way of the future”.
Fran Solomon (PhD, 1980, firstname.lastname@example.org)
In 1980, I became the second woman to earn a PhD in fisheries at the UW. My program focused on water pollution ecology, emphasizing impacts of toxic chemicals on aquatic biota. I want to thank my dissertation committee, especially the late Dr. George Brown, who was the chair and a wonderful mentor, and Dr. Frieda Taub, who was also a wonderful mentor and an inspirational role model.

As the School approaches its centennial year (2019), we have been telling the stories of many of the important figures in SAFS’s development and evolution: deans, directors, faculty, and students. In fact, there have been many long-standing staff members who have played significant
roles in helping SAFS become a major academic and research institution. Tom Oswold Jr.
Kendra L. Daly (MS, 1991)
I originally came to UW as an undergraduate and received a BS degree in Oceanography. I then worked in the Oceanography Department for several years, participating on oceanographic expeditions in Puget Sound, the tropical Pacific, and the Arctic and Antarctic regions. When I
decided to go back to school, I enrolled in the School of Fisheries to obtain a better background in quantitative science, population dynamics, and animal behavior.
Increasing human output of carbon dioxide results in higher temperatures and in ocean acidification—the lowering of ocean pH and other chemical changes. Oysters are threatened by ocean acidification, while eelgrass may benefit from the higher carbon dioxide levels in the water. A new laboratory study asks whether culturing Pacific oysters (Crassostrea gigas) together with eelgrass (Zostera marina) can help both out.Read more
Many lakes are important sources of water for agriculture and other purposes, while also supporting diverse ecosystems. In a new study, a comparison is made between the food webs of two natural lakes that were dammed early in the 20th century. The neighboring lakes are nearly identical except that one (Lake Keechelus) experiences rapid drawdown of water beginning early summer while the other (Lake Kachess) remains fuller and fluctuates less in water height during summer, but is lowered to a lesser extent beginning early fall.Read more
Formal stock assessments are conducted for many large and valuable fisheries, but these typically require reliable catch data, estimates of trends in fish numbers, and age data from caught fish. In data-poor fisheries, these kinds of data are not available, resulting in difficulties in assessing whether they are overfished or sustainably fished. Now a new model called LIME has been developed that accounts for variability in recruitment (the number of baby fish produced each year), and can assess status from samples of the lengths of fish in each year, together with whatever additional information is available.Read more
Many populations of native steelhead trout in the Pacific Northwest US are threatened by disease, habitat loss, poor ocean survival, and genetic mixing with hatchery steelhead trout. Steelhead are a form of rainbow trout that migrate out to the ocean when young, and return to spawn, just like many salmon species. Hatchery-produced steelhead have lower survival in the wild because they become less afraid of predators; one of the resulting concerns is that interbreeding between hatchery and wild steelhead will erode the natural fitness of wild steelhead and hinder their recovery.Read more
Salmon returning to streams and lakes in Southeast Alaska are affected greatly by water temperatures both in winter and summer, and these temperatures are projected to increase given climate warming. Changes in water temperature affects the time it takes for salmon eggs to hatch and emerge, and the timing of salmon returning to each stream, as they seek to avoid dangerous peak stream temperatures.Read more
