This semester we’ll be using a product hosted at slack.com to interact relating to lab projects which involve modeling actual fisheries management and use scenarios.
First, though, you need to get the App.
As part of your pre-lab activity you’ll be required to stage the Slack app on the device you use the most. It’s suggested you install the app on a few devices (if you have more than one) so you can see how it works on multiple platforms. The messages synch between devices, so you can start a conversation on your desktop, use a browser on a school computer, and even finish up a communication thread using your phone. It’s up to you.
These are some of the things we’ll be doing with Slack:
Make official public requests and posts based on your user role in the scenario
Communicate with other users privately
Share pictures and other files with your lab team
Ask questions of your Instructor
You may want to view this quick Introduction to Slack. We’ll go over more specifics in lab and make sure everyone can use the tool.
Contemporary patterns of salmon production and ecology is shaped by deep time following the end of the last ice age
Although the ‘Canadian’ Yukon comprises only 1/3 of the watershed, these streams produce approximately 1/2 of the fish
Juvenile downstream movements (which Dr. Bradford termed ‘dispersal’) differ among watersheds with relatively large vs. small amounts of habitat
Approximately 40% of Canadian produced salmon move downstream to non-natal streams
Groundwater and ice dynamics are key in understanding the potential for a stream to be conducive to rearing juvenile Chinook Salmon
Big changes in stock productivity (the numbers of recruits per spawner) has varied through time and most recent years the Canadian stock is more or less just barely replacing itself. Thus, little or no ‘surplus’ for harvest
Although the Yukon River watershed relatively pristine compared to watersheds in the lower 48, substantial habitat modification in the form of placer mining. However, habitat disruption unlikely to sufficiently explain patterns of production
Land in Canada belongs more to Provinces than Federal government compared to the US
First nations and distributions of salmon spawning stocks are entwined
Due to reduced harvest downstream in 2015, over 80,000 Chinook Salmon survived to make it back to the Canadian side of the border
Alternative management strategies differ in complexity (single vs. multiple stocks), risk to small unproductive populations, and recognition to lack of recognition of diversity
Some background on Dr. Bradford from his DFO research profile:
Currently, Dr. Bradford is working on some statistical models for coho smolt production, and finishing up the analysis of juvenile chinook salmon ecology in the Fraser watershed. He is also conducting a small field project in the Yukon on the ecology and habitat use of small non-natal streams by juvenile chinook salmon. Dr. Bradford is a quantitative ecologist with a wide range of skills, experience, and research interests. From 1992 to 1996, he was the manager for a FRAP project on the freshwater ecology of chinook salmon of the upper Fraser River. He also conducted research on the effects of flow reductions on juvenile salmon, and consequently, he has been involved in Nechako River-related matters, as well as on a number of committees and groups working on B.C. Hydro-DFO issues. Dr. Bradford participated in the 1994 Fraser sockeye review, and has worked on the evaluation of lake fertilization. More recently, he has been looking at quantitative links between fish production and habitat, particularly for coho salmon. He is a member of the core group in Science dealing with coho conservation, as well as an international group working on coho risk assessment. Dr. Bradford also sits on the PSARC Salmon Sub-committee. A common theme to his most recent projects is the explicit incorporation of risk and uncertainty in resource management decision making. Most of the research has been or is in the process of being published in peer-reviewed journals.
These are a few of the things that emerged from today’s conversation with Erin Harrington
Alaskan connections to salmon are virtually universal in the state and transcend simple political and religious lines
Knowledge is place based, which is simultaneously empowering (individuals protect those things they love, and typically love the things they know locally) and inhibiting (creates a myopic bias that can keep individuals from seeing the bigger picture)
Maintaining the connection and relationship to salmon by Alaskans is a tangible goal for increasing likelihood of sustainability
Sustainability is, at least in large part, an emergent property of locally adapted salmon populations and habitat diversity
A single assessment of ‘the state of Alaska salmon’ would be misleading as the issues are local (place-based) and differ among regions
Salmon issues are often (usually?) depicted in the context of conflict among user groups
Measuring success of social campaigns is difficult at best
Erin Harrington was raised in Juneau and Kodiak, the daughter of a commercial fisherman and an early childhood education advocate, and has fished the waters of the Gulf of Alaska, Bristol Bay and the Aleutian Islands. She received her undergraduate degree at Middlebury College in Vermont and holds a Masters degree in Seafood Marketing & Economics from the University of Alaska Fairbanks. She has worked at the intersection of fisheries, community development and public policy for 15 years. Erin is passionate about community and the impact of individual actions, and believes that we do our best work at the outer edges of our comfort zones.
