Sustainable Aquaculture for California – Make it Local
Sponsor an annual colloquium on research needs of the aquaculture industry.
Generate support for infrastructure to create state-of-the-art facilities.
Advance research designed to answer relevant questions regarding sustainable practices.
Mike Graham and Scott Hamilton received funding from NOAA Sea Grant to investigate how integrated multi-trophic aquaculture of seaweeds and shellfish (oysters and abalone) may potentially mitigate the negative effects of ocean acidification on shellfish growth. Changing ocean pH is having negative impacts on oyster growers in the Pacific Northwest, and potentially on any shellfish growers, especially at the hatchery/nursery scale. Seaweeds, however, thrive off increased carbon dioxide and can buffer ocean acidification. We have added 24 new 300-gallon tanks to create a replicated design to assess the effectiveness of various species of seaweed in mitigating different acidification scenarios on the growth and health of shellfish. In addition to providing much needed experimental scientific information on the effects of ocean acidification on shellfish hatcheries/nurseries, this project may demonstrate the utility of land-based integrates seaweed-abalone farms for expansion of the shellfish industry in California. Monitor the aquarium oxygen levels here.
Scott Hamilton has received funding from NSF, NOAA Saltonstall-Kennedy, and California Sea Grant to assess the impacts of ocean acidification (OA) and hypoxia on temperate fishes. Current work involves studying how these climate change stressors can (1) affect reproduction and embryo development in multiple species of groundfish and (2) impact the behavior and physiology of juvenile fishes. We have added a new trailer with computer controls to allow precise control of pH and dissolved oxygen in 24 new tanks to assess the impacts of changing ocean chemistry on commercially important fishes. Water quality of these tanks are continuously monitored and published data can be seen here.
Partnership with industries aimed at solving real problems in aquaculture science and production, and addressing broader societal issues (e.g., biofuels/energy independence, food security, and restoration of natural populations).
With funding from Anthropocene Institute and a collaboration with Kerstin Wasson (Elkhorn Slough National Estuarine Research Reserve) we have started a hatchery for the native Olympia Oyster (Ostrea lurida) with the intent of restocking impacted populations of this oyster in Elkhorn Slough and possibly later in San Francisco Bay. This project also requires the culture of microalgae as a food source for the developing oysters. We also monitor the water quality where these oysters are kept and published data can be seen here.
