University of Washington
University of Washington
• 45,000 students
• 4,351 faculty
• 2nd largest recipient of Federal research
funding of all U.S. Universities
SAFS
• 30 Faculty
• 100 undergraduate majors
• 100 graduate students masters and Ph.D.
A Research University Role
• Teaching – degrees and short courses
• Research – wide range relevant to
fisheries management issues
• Service – standing committees and ad hoc
advisory roles
NOAA a special relationship

•
Pipeline for students 9/40
Funding for faculty salaries
Students working on stock assessments
Bi-weekly joint workshops
Many other collaborations
– Foreign post-docs
– Year end money
Interaction in management
system
• Service on Science and Statistics
Committees of Regional Councils
– Punt and Anderson
• Chairing ad-hoc science reviews
• Serving and chairing NRC panels
commissioned by government
Salmon research in Alaska
• Bristol Bay freshwater salmon research
– Initiated in 1947
– 5 Field camps on Wood River and Iliamna
– Field research, Pt. Moller test fishery, work on
forecasting
Program objectives
• Provide scientific basis for sustainable
management of the sockeye resource
• Provide training for graduate and
undergraduate students
• Provide information useful to fishermen
and processors (pre-season and inseason forecasts)
Funding Sources
• Processing Industry since 1947 ($200,000
per year)
• U.S. Foundations ($14 million since 2002)
• Bristol Bay Economic Development
Corporation (community group) $2 million
in last 10 years
• National Science Foundation ($5 million
since 2002)
Scope of program
• Six faculty – Ray Hilborn, Tom Quinn,
Daniel Schindler, Lorenz Hauser, Lisa
Seeb, Jim Seeb
• 3 staff
• 7 graduate students
• 5-12 undergraduate students and
assistants
• 5 field camps in S.W. Alaska
Long term data sets
• Physical factors, temperature, lake
level, solar radiation
• On-ground escapement counting
– Age composition – validation of air counts
•
•
•
•
Freshwater growth of sockeye
Trends in sockeye food
Competition with other species
Predation by other species
BB OEG Study
• Initiated by Board of Fisheries
• Funded and organized by BBEDC
• Hilborn and Anderson did the
management strategy evaluation
Outer Port Heiden Study
• Genetic sampling of catch in area of mixed
stock fishing
• Funding by BBEDC to provide data on
whose fish are being caught
• Main costs are vessel charter and genetic
analysis of the data
Run reconstruction
• Statistical models to estimate the stock
composition in mixed stock fishing areas
• Developed in our group – methods used
by management agency
• Ultimately we need to train the
management agency staff to use the
software
Status of fish stocks and what
leads to good outcomes
Motivation
All fish gone
by 2048
Science 2006
More Motivation
Pauly’s “status of fisheries” from catch data
From Pauly 2007
The RAM Legacy data base
Typical data in RAM Legacy
• Abundance, landings, and recruitment
• Biological parameters, reference points
such as MSY, BMSY, uMSY or agency
targets

Coverage in the stock assessment data
base (38% of global catch)
Geographic coverage
• Well covered: US, Europe, Canada,
Australia, New Zealand, South Africa,
Argentina, Chile, Peru, Japan, Russia
• Well covered: high seas tuna fisheries
Major gaps
• China, Indonesia, India
• Africa other than South Africa and NW
Africa
• Invertebrates, especially large squid
fisheries
Forms of analysis
•
•
•
•
•
•
Trends in abundance
Trends in fishing mortality
Status relative to reference points
Lost yield from overfishing or underfishing
Factors leading to good outcomes
Importance of regime shifts, lack of
repeatable relationship between biomass
and productivity
Major scientific results
• Over 20 scientific papers showing that
most stocks that are assessed are not
collapsed or overfished and that
overfished stocks will recover if fishing
pressure reduced
• Papers showing that environmental
changes in productivity are common
Building a global network
Our objective
• A global network of people and data bases
• Provide on-line access to the best source
of data on the status of fish stocks
• Hold an annual meeting of the network to
review new science
Summary
• For an academic department to interact
effectively with a management agency the
academics must provide something not
available to the agency – skills, people etc.
• This requires interpersonal relationships
and years of contact
• Academics must always recognize that the
agency has a role that you don’t try to
usurp – particularly management advice!
More Summary
• Benefits to the academics
• Real problems and satisfaction of working
in real world
• Funding for the research
• Jobs for the students
