Sustainable Aquaculture
Encouraging aquaculture that addresses social, environmental concerns
Sea Grant-supported science has worked for decades to help commercial aquaculture produce safe, healthy stocks of native oysters and other species that at one time had nearly vanished from the region due to overharvesting and pollution. We support research into shellfish breeding, cultivation and disease, and have helped develop innovative processing and packaging techniques that help bring safe, fresh-tasting seafood to market. We are working with commercial growers up and down the coast to develp best practices that improve their products, expand their markets and ensure long-term viability through sustainable practices.
Reviving native oysters through research and education
Contact: Chris Langdon:
Oregon Sea Grant has helped support Chris Langdon's research into shellfish breeding, cultivation and disease since the early 1990s, well before Langdon was named head of OSU's Molluscan Broodstock Program at the Hatfield Marine Science Center in Newport. Sea Grant funding helped Langdon develop a new, easily grown red-algae food source for abalone, helping propel the nation's first large-scale commercial abalone farm. Additional Sea Grant funds have supported Langdon's continuing work on oyster disease and pathogens, in an effort to bring back back native oyster populations that had all but disappeared due to overharvesting and pollution.

Moving into the future: New Sea Grant aquaculture specialist
Contact: David Landkamer
In a renewed commitment to Oregon aquaculture, Sea Grant has named David Landkamer our new Extension aquaculture specialist. A former aquaculture expert with Sea Grant programs in Minnesota and Guam, he will be focusing primarily on on the shellfish industry's concerns about disease, broodstock tracking, ocean acidification and invasive species monitoring. Working with reseasrchers and Sea Grant Extension colleagues, Landkamer hopes to help shellfish growers - and other potential aquaculture industries - navigate the regulary waters, address water quality issues and better understand the commercial and consumer environments for shellfish products.
Developing best practices for ornamental fish breeders, importers and hobbyists
Contact: Tim Miller-Morgan
U.S. domestic production of ornamental koi is estimated at more than $6 million a year, but the vast majority of these popular and costly ornamental fish are imported from abroad. Koi herpes virus (KHV) is a growing concern in the industry because a single infected koi can kill an entire collection. Oregon Sea Grant's aquatic animal health specialist, Dr. Tim Miller-Morgan, teamed with the universities of Florida and Arkansas to develop and disseminate information and training on KHV, its diagnosis and prevention, and presented the information in workshops for koi dealers from around the world. The effort led to increased use of quarantine facilities by dealers and hobbyists, and a significant drop in the number of Japanese koi lost to the disease in shipping, saving US importers at least $75,000 a year.
