Centennial Story 49: Loveday Conquest, Faculty, 1978 – 2014 (Emeritus, 2014 – present)

I was fortunate to be in elementary school when the Soviets sent up the Sputnik satellite in October, 1957. This galvanized the United States government, in addition to ramping up the US space program, to launch a variety of “new math” programs for students, including female students, a rather bold move in those days. Female students who were identified as having mathematical abilities were encouraged to pursue mathematics and other STEM fields, even without the legal backing of Title IX (which did not come into being until the 1970s). I was one of the lucky ones. At Pomona College (Claremont CA), of the 30 math majors, three of us were women. Although there were no female math faculty, many of the math professors considered us almost as daughters, determined that “our girls” (to them, we were always girls) would be admitted to graduate school in whichever fields we wished to pursue. Thus, I ended up at Stanford University to complete an MS in mathematical statistics. I then entered the UW to pursue a PhD in biostatistics through the former Department of Preventive Medicine, today the School of Public Health. (An interesting side note is that Vince Gallucci graded part of my written PhD qualifying exam when I was a grad student. Vince wasn’t sure if my answer showed a full grasp of the true meaning of “randomness”!)

I began my academic career in 1975 at the University of Hawaii’s Manoa campus in the School of Public Health. Being from the Islands, I felt that if I didn’t give this opportunity at UH a try, I would always wonder if I should have. In those days, communicating with places on the mainland (especially DC, 5-6 hours’ time difference) was difficult without email. Phone calls and faxes were expensive. Attending a statistics conference on the mainland was difficult and attending a European conference meant traveling halfway around the globe. And the cost of living in Honolulu was quite high.

I was informed of a temporary vacancy in the UW’s School of Business; my mainland colleagues suggested that I could use Seattle as a “jumping-off base” from which to do a further job search. I expected to be in Seattle for exactly one year. Then came a phone call from Doug Chapman encouraging me to apply for an upcoming faculty post in the then School of Fisheries, teaching courses in probability and statistics through the Center for Quantitative Science in Forestry, Fisheries, and Wildlife (CQS), and doing quantitative research in natural resource management (NRM) areas. I went through the interview process, gave a seminar on the Behrens-Fisher Problem (George Brown told me years later that he specifically attended my seminar to see if I could indeed convey statistical ideas to a biologist), and received an offer to start in September 1978. At first, I wasn’t exactly sure how I could integrate myself as a statistical scientist into NRM problems, but as we all now know, there are so many quantitative issues arising in NRM, that it was not difficult to find colleagues in both Fisheries and Forestry who were eager for my collaboration. I spent many years working with Frieda Taub on her Standardized Aquatic Microcosms project (students would recognize numerous “SAM”-based examples in my class lectures). A multi-year quantitative fisheries project funded by the US Agency for International Development took me, Vince Gallucci, students, and staff to the University of Costa Rica and to the marine lab in Bolinao, Philippines. After David Ford (Forestry) arrived in 1985, the Quantitative Ecology and Resource Management (QERM) program emerged out of what had previously been the quantitative NRM arm of the old biomathematics program. I was in at the start of the Center for Streamside Studies (CSS), when Bob Naiman was hired as director, and worked with students from Fisheries, Forestry, and QERM through CSS over many years. A final major project for me was funded by the NSF in the area of marine sciences education. Graduate students from various areas in what would become the College of the Environment, and the College of Arts and Sciences, were paired up with high school environmental science teachers from two locations, Seattle (an urban school district) and the San Juan Islands (a rural school district). The teachers gained from having graduate student researchers working in their classrooms, bringing current research to high school students. The graduate students gained from being compelled to present their own research and other science topics to an audience not consisting of their peers, valuable training for anyone.

In the early 1990s, I became associate dean of the former College of Ocean and Fishery Sciences (COFS, and served with two deans, Ross Heath and Arthur Nowell. During those years, there was much necessary engagement with the community and the Jensen Boat Company as the UW negotiated to build new buildings in what is now called Southwest Campus. I also worked with various student and faculty groups underrepresented in COFS and the UW in general, which has led to my being involved with the American Indian Science and Engineering Society (AISES). I served as inaugural director of the UW Teaching Academy, followed by a stint as associate director of SAFS. And somewhere in there, I also directed the QERM program for about fifteen years following David Ford’s tenure.

In retirement, I have found myself answering the occasional call from Undergraduate Student Services in Mary Gates Hall when they need faculty members for various “Career Day” experiences with students. A recent Career Day saw the UW bus in 5th grade students from Neah Bay to the Seattle campus. Students were able to visit various parts of campus and to speak with current and former faculty (particularly women and faculty of color) about careers. I still attend the annual AISES conference, where it is inspiring to see hundreds of Native American, Alaska Native, and Native Hawaiian students presenting their STEM research and being recruited by companies such as Boeing and Intel for jobs and internships.

Retirement has also brought the call to serve on various boards and committees dealing with education, the arts, literature, Children’s Hospital (I model in vintage fashion shows, which raise funds for uncompensated care), and the downtown Women’s University Club, which emphasizes continuing education. Thus, I find myself frequently in planning meetings for various classes or speaker topics, and needing to find instructors, available rooms, and audiovisual equipment—not unlike tasks I used to do at the UW. (A major task can be reserving a parking place for the instructor!) And I now treat myself to participating in short courses in the UK at Oxford or Cambridge, where one lives in the dorms and experiences the best part of college life (although the chefs have admitted that we paying guests are treated to a higher class of food). So I get to go back into the classroom, this time as a student, with homework (lots of readings), but no tests nor grades—the best way to be in school at this time of my life.


Centennial Story 49: Dean Adams (BS, 1994; MS, 1998)

My experience at SAFS in the 1990s was nothing short of magical. I returned to UW when my livelihood in Alaska—commercial fishing for halibut and sablefish—came under threat due to overcapitalization and severely reduced fishing seasons. I needed to diversify my talents and expand my capabilities by completing a bachelor’s degree.

I was an outlier and an older student. I was a veteran of Alaska longline fishing, as well as an experienced fisheries advocate. I remember smiling when I listened to my profs lecture: Ted Pietsch, Tom Quinn, David Armstrong, Ray Hilborn, Loveday Conquest, Don Gunderson et al.—I got to learn from the best in the field.

As an undergraduate, I contributed to the School by guest lecturing in Kane Hall to several hundred students in FISH 101, primarily arts and humanities majors, who knew FISH 101 as a “fun” science requirement class. I also presented to the School of Marine Affairs (now, School of Marine and Environmental Affairs) regarding fisheries “limited-entry” management, a dynamic and highly charged political issue in Alaska at the time.

I became part of the SAFS network. Julia Parrish and Ed Melvin asked me to review their research proposal concerning seabird bycatch mitigation. This opportunity morphed into a voyage onboard my fishing vessel—the QUEST—where Julia and Ed established protocols for a large study that tested seabird deterrent devices. I am very happy to have been associated with this project, which led to regulations requiring the use of mitigation devices in the North Pacific longline fisheries.

If I had to pick my highlight at SAFS, it wouldn’t be my MS project, proving or disproving whether a so-called “Dirty-Dozen” group of trawlers existed in the Alaska fleet… (results “disproved” the moniker). Rather, the all-time highlight began during an undergraduate lecture by Tom Quinn, when he offered a nebulous project to his entire Fish Ecology class— studying fish migration in the Columbia River. No takers then; however, some time later when Tom advised me on how to tick off all the boxes and complete my degree, he said I should consider doing this project, and as a tradeoff, petition to omit a couple of required courses regarding fishing gear technology and world fisheries issues. I pondered for a moment and took him up on his offer. I am so thrilled that I did… it evolved into a 1996 paper in the journal Ecology with Tom and me as authors. It is a wonderful and oft-cited paper concerning global warming affecting the migratory timing of anadromous fish.

Finally, and directly related to my experience at SAFS, is my confidence in academic discipline, without which I would have never been able to take on the enormous project of writing a book— “Four Thousand Hooks,” published by UW Press in 2012. Tom and Ray Hilborn are in the book’s acknowledgements.

I am so very grateful to have been part of UW SAFS.

Micro-slices of fish scales reveal effects of dams on lungfish diet

Australian lungfish are living fossils that have survived virtually unchanged since their appearance in the fossil record 340 million years ago. They are well known to have the nifty ability to survive for several days out of water. Now, a new study uses their scales to infer what they ate over periods of more than 50 years. The new technique first ages the lungfish by measuring radioactive signatures in the scales that track radioactivity from nuclear weapons testing in the 1950s and 1960s, and then having dated micro-slices of the fish scales, each slice is examined for carbon and nitrogen isotopes that unveil their food sources throughout their life. The results show that Australian lungfish shifted from food sources on river bottoms (typical of pristine streams) to food sources found in the water column, after their rivers were dammed. In addition, their scales reveal a period when the dairy industry expanded and nitrogen fertilizer in the water increased, and then nitrogen levels declined again as diary pastures dwindled. The new research was led by SAFS professor Julian Olden, and is published in River Research and Applications.


Exploring the Phoenix Islands Protected Area with SEA Semester

On a deserted island in the middle of the Pacific, a group of young scientists uncover an unassuming hunk of metal, called a FAD or fish aggregating device, that stranded ashore. Rumor has it famed aviator Amelia Earhart was also marooned on this very island over 80 years earlier during her ill-fated trip to circumnavigate the globe.

Today, however, Nikumaroro Island is one of many valuable research sites for students in the SEA Semester program offered through the Woods Hole Oceanographic Institute. Andrew Chin, a University of Washington senior majoring in Aquatic and Fishery Sciences and Marine Biology, and his classmates in the program are combing the remote beaches of the island looking for more FADs —evidence of illegal fishing in one of the largest marine protected areas in the world.

During a month at sea (following three weeks of study on shore at Woods Hole), the class of 19 students hone their sailing and scientific skills aboard the SSV Robert C. Seamans as part of the intensive program.

Departing from Honolulu HI, the path of the SSV Robert C. Seamans takes it south-west toward American Samoa, sailing through the Phoenix Islands Protected Area (PIPA). The PIPA is roughly the size of the state of California and is comprised mostly of open blue water save for a few uninhabited coral atolls.

“There’s a lot of history on those islands and walking around and seeing that history is really cool. You take a small boat up to the beach and you get off… and just knowing nobody is there. There used to be at different periods of time, but now you’re the only people on this island. You’re just walking along the edge of this atoll and there’s birds flying all around. It’s really spectacular,” says Chin.

Aboard the vessel, Andrew and the other students will spend the summer working alongside the ship’s crew, engineers, scientists and lab hands. During this time, they will collect and analyze oceanographic data; investigate our impacts on ocean and coastal health; critically evaluate management practices; and identify significant relationships between economics, technology, government and the environment.

The FAD Andrew and the other students found on Nikumaroro is one of 16 recovered that day along a three-mile section of beach.

“We received a letter from the PIPA office which said they were getting reports of fishing vessels along the border using FADS and that currents were diverting them to Nikumaroro Island,” says Chin.

He explains commercial fishermen deploy these circular floating objects, which are about two foot around and resemble spotlights, on the outskirts of the PIPA and let them drift through to the other side. As the FADs move through the water it acts as an oasis in the vast open ocean, attracting fish and other marine life like a magnet. The fishermen can track and monitor how many fish are beneath the FAD and then harvest the catch after it passes through the protected waters.

Sometimes the FAD never completes its intended journey and the ocean currents wash them ashore the atolls dotted across the PIPA.

“They’re really sophisticated, Chin says. “We pulled them apart and were able to look at all of the circuitry. They have a GPS transmitter, fish sonar, solar panels and an iridium chip you can actually use to track where it was manufactured and who bought it.”

Discovering these FADS and the implications of their use is just one of many examples of how students can engage in real-world conservation and management issues during their summer with the SEA Semester program. Research they collect will assist in the ongoing development of an effective conservation plan for the region.

Another draw of the program is to provide students an opportunity to learn how to operate and sail the 134-foot SSV Robert C. Seamans. A daunting task for many who arrive on board with little or no sailing experience, but become quick studies under the crew’s guidance and the daily routine of life at sea.

“At one point the professional crew hands the ship over to us,” says Chin. “We had to run the ship, do navigation, do the deployments and stuff like that. We had to learn in that type of kinetic environment and then actually do it and take responsibility.”

Safety was always paramount while at sea. The entire ship would practice and participate in different drills to be prepared for an unlikely event such as a fire or person overboard. Each crew member would be assigned to a different team and have certain tasks they must be ready to perform during an emergency situation.

Various oceanographic studies also became routine: from CTD deployments which measure the conductivity, temperature and depth of the water to night-time tows where the students would use nets to collect fish and plankton specimens and catalogue them in an ongoing effort to monitor the biodiversity in the PIPA.

“The nighttime pelagic tows are really exciting because you pull up all these mesopelagic fish like bristlemouths, lantern fish and salps that are still glowing,” says Chin referring to the bioluminescence many deep sea creatures exhibit.

The SEA Semester experience provides students an exciting opportunity to explore the pristine waters, coral reefs and islands of the PIPA while also building a strong foundation in science, management and policy. Learning in such a dynamic environment opens amazing networking possibilities and lasting friendships.

“There’s so many small wonders that happen on the ship.”

“You’re out sailing through all these really cool places and you get to see a lot of the world,” says Chin. It’s also another way to connect with people who may not be doing science, but connect with them in such a personal way.”

What advice would you have for students considering SEA Semester?

“Dive head first into it. You’re going to be on this ship with these people in this very small space for like five and a half weeks. Be really open about making friends and talking to people and being involved. It’s a really awesome experience and you only get out of it what you put into it.”

“Apply early because there are a lot of folks are interested in this. Also don’t be scared by the high price tag because SEA Semester gives you a lot of scholarship opportunities along with UW Study Abroad and the Gilman Scholarship.”

Two new species of male mouth-brooding fish described

Two new species of jawfishes (family Opistognathidae) have been described for the first time this month. These small fish have fascinating life histories, digging burrows in sandy bottoms near reefs, and relying on males to brood eggs in their mouths. Each burrow houses one fish, and they strongly defend their burrows. The first new species, Thionyi’s jawfish (Opistognathus thionyi), is found in Vitória-Trindade Chain and Fernando de Noronha Archipelago off Brazil; while the second new species, the Brazilian dusky jawfish (Opistognathus vicinus), is found off mainland Brazil. The new species are differ externally and genetically from previously described species in the same genus, which are extensively reviewed in the published research. The paper by William Smith-Vaniz of the Florida Museum of Natural History, SAFS professor Luke Tornabene, and Raphael Macieira of the Universidade Vila Velha, Brazil, appears in the journal Zookeys.

Little change in polar bear numbers in the Chukchi Sea

Polar bears, like other large predators, are hard to track and count, and available data is often fragmentary and difficult to piece together. Now, a new model provides estimates for key parameters for polar bears in the Chukchi Sea off north-western Alaska, by combining available data from telemetry, marking and recapturing, and counts. The model estimates that 83% of females give birth every year, that litter sizes are 2.11 per year, and that survival is about 90% for both males and females. Densities of polar bears in this region appear little changed from surveys in the 1980s, and suggest that this population contains nearly 3,000 polar bears (although the numbers could be anywhere from 1,600 to 5,900). The new research was led by Eric Regehr of the US Fish and Wildlife Service, included SAFS professor Sarah Converse among the coauthors, and was published in the journal Scientific Reports.

Fish processors pay higher prices after individual quotas

Individual fishing quotas have been introduced to the Pacific whiting fishery off the US west coast, involving allocating rights to fish quota to both harvesters (80%) and processors (20%) and letting individuals decide when and how to to catch and land fish. A unique dataset of prices and costs allowed researchers to examine the impact of this change on land-based processors. Such an examination has not previously been possible in any fishery because cost and income data from processors is rarely, if ever, collected. The data show that fish landings were more spread out, with landings at the major processors increasing from 38 to 72 days, and that processors ended up paying a greater share of the export price to harvesters (leading to prices averaging $0.068 per pound higher). Processing efficiency, while headed towards greater efficiency, was not clearly better, although data were limited given the small number of processors. The new research by Marie Guldin (Northwest Fisheries Science Center, NOAA) and SAFS professor Christopher Anderson, appears in the journal Marine Resource Economics.


Strong individual rights emerge naturally in gaming experiments

Many natural resources, such as grazing lands, forests, and fisheries, can be managed either by lots of people communally (common property), by top-down regulation, or by individual rights. A new analysis shows experimentally that individual rights emerge as the preferred choice when people are given freedom to choose among different clubs that each decide how to manage part of the resource. The experiments mimicked the setup in the Northeast US Multispecies Groundfish Fishery, where there was strong opposition to allocating individual transferable quotas (ITQs) to each participant—which would have allowed each participant to catch a portion of the total catch, and lease or sell that right to others. Instead, sectors (“clubs”) were set up that each controlled a portion of the total catch, and users in each sector could decide how to fish the resulting quota. Lab experiments examined how individual users responded to this kind of setup, finding that individuals tended to move to clubs that allocated individual rights over time, because they were more profitable. However, just like in the real-life fishery, a few users continued to favor systems where fishers competed against each other rather than owning and fishing their portion of the quota. These fishers preferred the competitive nature of fishing derbies over the profitability and security of individual rights. The results suggest that it is not necessary to impose individual rights on all members harvesting a natural resource. Instead, self-identifying clubs of users can be granted considerable autonomy in how they manage a portion of the total allowable extraction, and individual rights will likely emerge naturally if they are the most profitable system. The new work by Mihoko Wakamatsu of Kyushu University, and SAFS professor Christopher Anderson, appears in the journal Ecological Economics.

In the lab experiments, profits from clubs using individual fishing rights (IQ) are consistently higher than profits from common pool competitive fishing (CP).
Over the course of the experiment, more and more participants switched from clubs with competitive fishing to clubs allocating individual fishing rights (IQs).

Too many fish, too few hooks: examining bias in hook-and-line surveys

Scientific surveys using fishing rods, each fishing multiple hooks, have the advantage of being able to access rocky areas while obtaining samples of fish for length and age estimation. However, in areas with lots of fish, it is possible for nearly every hook to catch a fish, resulting in an upper limit on the number of fish that can be counted. This problem of hook saturation can lead to catch rates not directly matching trends in fish abundance in the area being surveyed. A new simulation study delves into this problem, finding that catch rates do indeed decline more slowly than abundance for hook-and-line surveys, and that surveys targeting sites with higher densities of fish are able to better track changes in abundance. In addition, competition for hooks among species can lead to bias when one of the species more aggressively attacks baited hooks. Nevertheless, hook-and-line surveys fill a vital role in assessing the status of species that cannot be surveyed by other methods. The research was conducted by recently-graduated SAFS PhD student Peter Kuriyama, SAFS professor Trevor Branch, Allan Hicks of the International Pacific Halibut Commission, and John Harms and Owen Hamel at NOAA Fisheries, and appears in the Canadian Journal of Fisheries and Aquatic Sciences.

Catch per hook (CPUE) declines more slowly than abundance across a variety of scenarios. As the number of sites fished increases, CPUE becomes more precise (smaller vertical lines indicating uncertainty), regardless of the way in which fish are distributed from area to area (rows of figures). In most scenarios, hook-and-line surveys are still able to detect declines in fish abundance (filled black surveys) unless the declines are small, few sites are surveyed, or fish are distributed in a very patchy fashion (white circles).

Fantastic beasts and where to find them

New and weird species are being discovered all the time, and the latest is the Narungga Frogfish (Histiophryne narungga), which has just been described. The name honors the Narungga tribe of indigenous Australians who traditionally inhabited the lands in which it was found. The new species comes in a variety of dotted forms, occurs in southern and western Australia, and is a member of the order Lophiiformes. The new species is described in the journal Copeia by Rachel Arnold of the Salish Sea Research Center and SAFS emeritus professor Theodore Pietsch.
