SNAPP: Sustainable Open-Ocean Aquaculture

Analyzing Best Practices and Standards

Principal Investigator(s): 

Dietmar Grimm, Ben Halpern

Aquaculture currently represents 50% of all fisheries products for direct human consumption. This means that aquaculture production exceeds global beef production in terms of protein produced. Aquaculture will continue to be a major source of protein for global consumption, but how can the scientific community help to steer aquaculture towards more environmentally sustainable practices?

This SNAPP project will examine specific dimensions of the “aquaculture problem”, and synthesize its findings in a forward-looking prospectus for the emerging offshore open-ocean subsector (versus near-shore fish farming). The four scientific products of this working group will focus on:

  1. A review of the real and perceived risks of open-ocean aquaculture relative to the near shore approaches. The Working Group will review both grey literature and peer-reviewed articles, as well as interview industry representatives and ecologists who have expertise in geographies where aquaculture operations are either already well-established and/or are rapidly expanding. Drawing upon the array of concerns and impacts that have already been measured in a near shore context, the Working Group will disentangle actual offshore impacts, concerns, and possible improvements that will help clarify the potential of open-ocean aquaculture.
  2. An analysis of the economic and ecological opportunities for expanding open-ocean aquaculture with an emphasis on approaches that target the most favorable options for jointly meeting economic needs and ecological needs. The Working Group — which includes industry leaders, conservation scientists with expertise in ocean health, and NOAA experts who contributed to the National Strategic Plan for Federal Aquaculture — will identify and map areas with greatest opportunity (‘hot spots’) for “smart aquaculture” with high potential aquaculture productivity, and minimal conflict with biodiversity and critical ecosystem services.
  3. Equally as important is avoiding areas most at risk and/or least viable for open-ocean farming expansion. As such, the Working Group will also analyze areas that should be avoided given a series of important ecological, social, and economic considerations (‘cold spots’).
  4. Looking towards an expansion of sustainable open-ocean aquaculture requires a quantitative assessment of the needs and conflicts of fish production now and into the future. The Working Group will evaluate open-ocean aquaculture operations and production in 2015 and forecast the potential into the future by exploring and modeling trends in wild fish capture and consumption, climate variability, technological advances, and food security and safety. Critical to evaluating the prospects of open-ocean farming will be involving key stakeholders in the aquaculture industry throughout the process.
