Administration

[M/170-01]

2/1/2006 – 1/31/2008

Alaska Sea Grant and its extension arm, the Marine Advisory Program (MAP), help people understand, conserve, and wisely use Alaska's bountiful coastal and marine resources. We've done this through a program of research, education, and extension activities to people across the state. Our program has grown to include advisory offices in nine Alaska communities that provide strategic geographic coverage of the Alaska coast.

An active management team integrates the several components of Alaska Sea Grant/MAP and creates a tightly woven administrative fabric. The team is led by Dr. Allee, and other members are Paula Cullenberg, MAP leader and ASG associate director; Kurt Byers, Education Services manager; and Michele Frandsen, program manager.

The ASG director has implemented a new 2004–2010 strategic plan, developed with the assistance of the Alaska Sea Grant Advisory Committee. The Advisory Committee is composed of prominent constituents from throughout the state, with diverse backgrounds and a common interest to put us to work for the people of Alaska. With their varied and fresh perspectives, committee members have provided new insights on the critical and essential issues where we can most effectively serve Alaska. The Advisory Committee holds meetings each fall, and is active in the research proposal review and selection process.

In addition, over the next few years an active Alaska Sea Grant marine education program will be initiated. In the near term we will revise the Sea/River Week curriculum while preparing for expansion in new areas, such as Alaska Native students in fisheries science and an Alaska Sea Grant fellowship program.

All of this activity is an exciting enterprise for the staff of Alaska Sea Grant, MAP, and the Advisory Committee members. The Alaska marine resource landscape is changing, and the issues and answers to problems are complex. This complexity of marine resource issues poses challenges to Alaska Sea Grant and other organizations, and demands a disciplined approach to problem solving. Guided by a thoughtfully composed strategic plan, we will adjust our approach as needed and respond to the challenges—and will continue to achieve success.

With the Alaska Sea Grant organizational infrastructure in place, the objectives of program administration are

The Alaska Sea Grant program administration embraces the Vision and Mission statements laid out in the Alaska Sea Grant 2004–2010 Strategic Plan:

Vision. Alaska will have the nation's most vibrant and productive marine, estuarine, and coastal watershed environments, maintained through ecosystem approaches to management balancing wise use and conservation. Alaskan people and communities will reconcile different values about resource use and conservation by blending and applying objective, science-based, and traditional knowledge for the social and economic benefit of all Alaskans.

Mission. Alaska Sea Grant develops and supports research, education, and extension programs and partnerships to help sustain economic development, traditional cultural uses, and conservation of Alaska's marine, estuarine, and coastal watershed resources.

Advisory and Outreach

Marine Advisory Program [A/151-01]

2/1/2006 – 1/31/2008

In a state as big as Alaska, it's critical that people have quick and easy access to knowledge, training, technology, and information about the state's marine resources. Agents and specialists of the Marine Advisory Program (MAP) live and work in the communities they serve, linking Alaska Sea Grant and the University of Alaska to its constituents.

MAP's major focus is on the economic well-being of the state's coastal communities, particularly the commercial fishing, mariculture, and seafood industries. Agents and specialists work closely with charter boat operations, Native groups, subsistence and recreational users, school teachers, and others with an interest in coastal and marine resources.

Over the next two years, MAP will carry out numerous Alaska Sea Grant-supported activities, including continuing a highly successful industry training program aimed at boosting seafood quality and assisting the development of new seafood products and businesses. MAP agents and specialists will conduct community-based marine mammal and water quality studies, help to improve harbor water quality and develop watershed management plans, and assist the development of ecotourism and shellfish aquaculture, among many other projects. They'll also produce seafood training and awareness videos and public service video messages on important topics, and continue production of a public affairs television program series. MAP offices are located in Anchorage, Bethel, Cordova, Dillingham, Homer, Ketchikan, Kodiak, Petersburg, and Unalaska. To learn more about the Marine Advisory Program, visit the MAP Web site.

Education Services [A/161-01]

2/1/2006 – 1/31/2008

Working with the Marine Advisory Program and other agencies, Sea Grant programs, and experts, Alaska Sea Grant Education Services publishes books, organizes scientific conferences and public meetings and workshops, and uses the Web and the broadcast and print media to provide people with information about Alaska's marine, estuarine, and coastal watershed resources.

In 2006–2008, Education Services will publish and promote more than two dozen new books, brochures, and posters, including a first-of-its kind field guide to Alaska's sharks and skates. We will commence a complete update of our elementary-grade curriculum guides, Alaska Sea Week; create a new Alaska marine education resources Web site; and cosponsor the Alaska Summer Research Academy for Marine Science. We will carry our information to the public via trade shows, community festivals, and other public events. Information also will be conveyed by our radio series, Arctic Science Journeys Radio (ASJ). We will continue to offer an array of education and information services through our Web site, which includes our online bookstore and ASJ Radio's multimedia site. We will coordinate several workshops and symposia on sustaining fishing in small communities, including sustainability of the Arctic-Yukon-Kuskokwim salmon fisheries; benthic mapping; and ecosystems approaches to fisheries management.

Coastal Communities and Economies

A Global Analysis of Salmon Prices: How Low Can They Go? [R/32-03]

2/1/2006 – 1/31/2008 $197,348

Fishermen, processors, and fishery-dependent community planners need current information about salmon prices, given an ever-changing world marketplace. In this project, researchers will develop several predictive models that explore the possible future international market for wild and farm-raised salmon and rainbow trout. The models will incorporate production costs, tariffs, taxes, quotas, and other factors to better predict the impact on the price fishermen receive for Alaska wild salmon. Researchers will estimate how low Alaska salmon prices might need to drop to stay competitive, and what industry reorganizations might be needed to raise product prices or lower production costs so that the industry can remain economically viable.

Improving Yields of Pacific Oysters in Alaska [R/42-01]

2/1/2006 – 1/31/2008 $83,286

Because Alaska's remotely located shellfish farms mean higher production costs, and cooler waters slow oyster growth, shellfish farmers are looking for ways to improve efficiency and reduce operational costs to become competitive and sustain their industry's growth. One way to improve efficiency is to plant faster-growing oyster seed. Researchers will work cooperatively with the Alutiiq Pride Shellfish Hatchery in Seward, Alaska, and the Molluscan Broodstock Program at the Hatfield Marine Science Center, Oregon State University, to continue growth experiments of genetically selected Pacific oysters. The goal of the project is to develop fast-growing oyster broodstock to produce seed for the state's shellfish industry.

Responses to Coastal Erosion in Alaska: A Guide for Coastal Residents, Businesses, Resource Managers, Engineers, and Builders [A/75-02]

Orson P. Smith, School of Engineering, University of Alaska Anchorage 2/1/2006 – 1/31/2008 $56,912

A published guide is needed to help Alaskans cope with increasing coastal erosion. Researchers will prepare a comprehensive peer-reviewed guide describing the nonstructural responses and constructed responses to coastal erosion. Topics such as design features, strengths and weaknesses, cost and effectiveness, risk of failure, and potential impacts on adjacent shorelines and ecologies will be discussed. Long-term maintenance and climate change considerations also will be addressed. Alaska Sea Grant will publish the guide, which is expected to help coastal residents and businesses, coastal resource managers, and designers and builders of coastal public and private works make wise decisions.

Ecosystems and Habitats

The Seasonal and Interannual Patterns of Larvaceans and Pteropods in the Coastal Gulf of Alaska, and Their Relationship to Pink Salmon Survival [R/101-05]

Terminated

Juvenile pink salmon appear to preferentially feed upon two little-known groups of tiny marine zooplankton—larvaceans and thecosome pteropods—and these may be tied to salmon survival and returns. At present, scientists have poor estimates of the composition, abundance, biomass, and production of the larvaceans and pteropods. This project will provide the first detailed characterization of larvaceans and pteropods in the Gulf of Alaska, and will describe their impact on pink salmon survival.

The Interannual Variability of Zooplankton within Prince William Sound, Alaska: Assessment of the ZooScan System as a Tool for Optimizing Juvenile Pink Salmon Release [R/101-06]

2/1/2006 – 1/31/2008 $26,035

Knowing how much and what kind of prey is available is important in deciding when to release juvenile pink salmon from hatcheries and in predicting survival rates and ultimately the return of adult salmon. Researchers will assess data on zooplankton abundance collected over 20 years to better understand the timing of specific zooplankton abundance in relation to juvenile salmon release. This project also will test ZooScan, a new digital imaging system designed to measure the abundance, biomass, and composition of major zooplankton groups. If successful, ZooScan systems could be installed in hatcheries to offer real-time monitoring of prey availability that would improve the timing of juvenile salmon releases.

Analysis of the Collapse of the Kodiak Red King Crab Stock and Fishery [R/31-15]

2/1/2006 – 1/31/2008 $96,342

Alaska's red king crab fishery in Kodiak went bust about as fast as it boomed. After a few exceptional harvest years, the fishery has been closed since 1983. Because of interest by coastal communities in the potential to rebuild red king crab through enhancement, researchers in this project will conduct a retrospective analysis of the Kodiak red king crab stock and fishery, including the natural and anthropogenic factors surrounding its rise, collapse, and failure to rebuild. This study is expected to broaden understanding of major changes that have occurred in the Gulf of Alaska marine ecosystem, and aid in planning red king crab stock enhancement efforts.

Multispecies Fisheries Models for Ecosystem Decision Support [R/31-14]

2/1/2006 – 1/31/2008 $55,338

Even with the vast computing power and ecosystem knowledge available today, most fisheries are managed as a single species without significant consideration given to other species that may be affected. This project seeks to further efforts begun with Alaska Sea Grant to develop models that incorporate multiple species into management decisions. In the new work, researchers will alter North Pacific Fishery Management Council (NPFMC) harvest goals for each of five species in the Gulf of Alaska to evaluate alternative harvest strategies and test the viability of the model.

Exposure of Wintering Sea Ducks to Disease Agents and Parasite Burdens in Southwest Alaska [R/101-07]

2/1/2007 – 1/31/2008 $68,110

Sea ducks, most notably Steller's eiders, in Unalaska Bay appear to be in poor physical condition and have been exposed to a variety of disease agents. Poor nutrition, disease, and interactions between potentially immunosuppressive contaminants and diseases may directly affect Steller's eider survival on their wintering grounds. In this project researchers will assess sea ducks in Unalaska Bay, and within Izembek National Wildlife Refuge as a control, to determine whether high rates of disease exposure from Unalaska Bay are constant among years. With the data collected, they will assess the effect of disease agents and parasite burdens on population dynamics of sea ducks wintering along the Alaska Peninsula and Aleutian Islands. This study will provide information to local coastal communities related to current management practices of public water resources in marine species harvest areas. Findings will aid in the management of a federally listed threatened species, and spur cooperative partnerships with community wastewater treatment and seafood processing facilities to address potential contaminant problems.

Ma-ku (Dead Beached Sea Mammal): An Alaska Natives' Field Guide to Stranding Response [A/143-01]

Terminated

Alaska Natives live, work, and pursue subsistence activities along the coast, and are often the first people to witness a stranded marine mammal. Yet few Alaska Natives are trained to collect data and samples from the stranding for use by scientists and managers. Researchers will work with Alaska Native groups, scientists, and resource agencies to produce a field guide for stranding response specific to the needs of Alaska Natives. The guide will blend Western scientific knowledge and data needs with traditional ecological knowledge and practices to achieve the goal of gathering important data on stranded marine mammals. Such a culturally appropriate guide will empower Alaska Natives to contribute to the scientific management of marine mammals.

Outbreeding Depression in Pink Salmon: Effects of Hybridization between Seasonally Distinct Subpopulations (Phase 2) [R/31-13]

2/1/2006 – 1/31/2008 $191,571

Salmon that breed with other salmon outside their own distinct population may be less likely to pass on to their offspring traits that allow them to survive in the wild. These traits are said to become "depressed." Researchers will examine the extent of outbreeding depression in hybrids between related populations of early and late-run pink salmon in Auke Creek in both even and odd broodyears. They will observe traits likely to be depressed by outbreeding: primarily reduced marine survival of hybrids, but also changes in return timing, differences in development rate and embryo survival, and changes in the distribution of family sizes.

Acoustic Behavior of Salmon [R/21-01]

Terminated

Acoustic technologies, such as side-scan sonar, are commonly used to assess salmon escapement, especially within rivers too wide or muddy for direct visual counts. In rivers hosting returns of multiple salmon species, differentiating among stocks is critical to management. Distinguishing among salmon species has generally been inferred through the strength and shape of the sonar signal: larger salmon such as chinook reflect a larger, more intense sonar signature than do smaller salmon such as sockeye. However, fish behavior has been known to impose errors in acoustic counts. This project seeks to better understand how fish behavior influences the acoustic signal. A better understanding of behavioral effects on signal amplitude and shape will help scientists produce more accurate assessments of salmon returns that will improve salmon management.

Economic Impacts of Alaska Fisheries [R/32-04]

2/1/2006 – 1/31/2007 $58,290

Alaska's fisheries have large and important economic impacts. However, the nature and scale of these impacts are not well understood by policy-makers or the public, and reliable information about economic impacts rarely enters into discussion of fisheries policy. This project will systematically collect, analyze, summarize, and explain the economic impacts and benefits of Alaska's sport, commercial, personal-use, and subsistence fisheries, drawing on data from a wide variety of sources and analysis from a number of earlier studies. The broad objective of this project is to provide Alaska policy-makers and citizens with a useful tool in making public policy decisions.

Marine and Aquatic Science Literacy

Endangered Species and Sea Duck Teaching Kits for Coastal Alaska Public School Districts [A/141-01]

2/1/2007 – 1/31/2008 $18,422

Populations of 10 of the 15 known species of Alaska sea ducks have inexplicably declined, and biologists and waterfowl managers are rushing to determine why. To foster better public understanding of sea ducks and their coastal habitats, investigators in this project will develop and deliver K–8 curricula and teaching kits to 13 schools in western Alaska and the Aleutian Islands.

Seafood Science and Technology

Alaska Oyster Safety: Monitoring and Identification of Vibrio parahaemolyticus [R/51-04]

2/1/2006 – 1/31/2008 $1,844

In summer 2005, more than sixty Alaska tourists were stricken with food poisoning caused by consuming locally aquacultured oysters containing pathogenic Vibrio parahaemolyticus. In this project, researchers will set up a V. parahaemolyticus monitoring and testing system with aquaculture farms in Prince William Sound, Kachemak Bay, and Southeast Alaska. Further, researchers will study the cold-water tolerance of the pathogen in an effort to find creative, cost-effective ways to prevent accumulation of the pathogen in oysters.

Developing Microencapsulated Fish Oil Powder from Alaska Salmon Oil for Nutraceutical Markets [R/54-02]

2/1/2007 – 1/31/2008 $15,145

The value of Alaska salmon oil can be increased through purification and encapsulation for use as oil powders for the human-grade food industry. This study will develop an encapsulation delivery system for salmon oil and enriched salmon oil for use as food ingredients. Unrefined salmon oil will be purified using adsorption technology. Purified salmon oil will be evaluated for fatty acid profiles, free fatty acid content, lipid classes, peroxide values, thermal stability, melting point, specific heat capacity, and other properties. The polyunsaturated fatty acid (DHA and EPA) content of salmon oil will be enriched and optimized using enzyme-based technologies. Salmon oil and DHA- and EPA-enriched salmon oil fractions will be encapsulated with protein and/or carbohydrate to produce dry, flowable oil powders. The salmon oil powders will be evaluated for shelf-life stability, sensory quality, nutritional properties, product acceptance, and market potential.

Education and Training

Sea Grant Traineeships

2/1/2006 – 1/31/2008

Sea Grant traineeships provide the nation's future scientists with the educational and hands-on research tools needed to provide leadership to manage marine resources. To date, Alaska Sea Grant has provided 95 students with direct support of their Alaska Sea Grant–funded research. Most students graduate to productive careers in business, academia, and government, with nearly 40 percent remaining in Alaska. An investment of 20–25 percent of the program's federal funds is directed at education programs and traineeships. Over the next two years, 11 graduate students will receive traineeship support.

Additional objectives of the Sea Grant traineeships include:
