Utilization of Marine Process Waste for Aquaculture Feeds
Limited amounts of forage fish are available as an ingredient in feeds for the expanding aquaculture industry. Work is being conducted on a variety of underutilized materials to provide new sources of protein, oils, and minerals for fish feeds. These materials include invasive species such as carp and mussels, waste from fish and clam processing, and process waste from fish farms. Successful utilization of these materials adds needed protein and marine oils to the growing aquaculture industry, and eliminates the environmental impact of landfill or dumping at sea of these waste streams.

Research Themes

Sustainable, safe and secure seafood for healthy populations and vibrant communities
Effective fisheries management provides economic opportunities and ensures the long-term sustainability of fisheries and the habitats on which they depend. The NWFSC seeks to improve the quality and quantity of data used in stock assessments, the methods for assessing stocks and ecosystem sustainability within the context of human modification of the environment. The NWFSC also provides state-of-the-art science and technology to support aquaculture while protecting and maintaining ecosystem health. Further, pathogens, toxins from harmful algal blooms (HABs), chemical contaminants and other stressors of marine ecosystems pose significant risks to health of both seafood resources and to humans. The NWFSC focuses on research to improve understanding of those risks, how to forecast them, and identify means to mitigate their impacts.

Research Foci

Develop research and technology to foster innovative and sustainable approaches to aquaculture
The NOAA Aquaculture Policy calls for enabling sustainable aquaculture that provides domestic jobs, products, and services and that is in harmony with healthy, productive, and resilient marine ecosystems. To achieve these goals, NWFSC’s research examines scientific and technical issues to support aquaculture production. NWFSC research also considers potential impacts of aquaculture practices on the environment and on wild populations of fish and shellfish and methods for diminishing those impacts. Specific research objectives include (1) identify methods for reducing reliance on forage fish protein and oil in aquaculture feeds; this includes the evaluation of plant and microbe-based alternatives for fish meal and oil, because fishmeal and oil used in producing artificial fish diets is unsustainable and often a source of contaminants, (2) evaluate and model potential genetic impacts of aquaculture escapes on natural populations, (3) develop shellfish research that will support regional initiatives, such as the Washington Shellfish Initiative, especially native shellfish restoration and (4) develop new marine species for aquaculture and shore-based marine recirculating aquaculture systems.
