For over 30 years there have been numerous studies on the feasibility of integrating offshore aquaculture with non-renewable (oil, gas) and renewable (wind, wave, tidal, etc.) energy systems in the USA. Opportunities/ constraints have been reviewed, debated, revisited, re-reviewed, and debated again with no significant developments in offshore aquaculture , while offshore aquaculture speeds ahead internationally . The USA has t he best conditions in the world for the expansion of offshore aquaculture ; Kapetsky et al. (2013) found the US EEZ to have >5,800 km2 space for economically viable offshore production. Based upon Statistics Norway (2017) and Liabø (2011), biosecure salmonid aquaculture alone in this area could produce 8-18 MMT live weight ; other analytical predictions are higher when full consideration of the full panoply of the available marine species is given due to the wide range of temperatures available such as cobia, yellowtail, mussels/oysters , kelps, etc. FAO (2018) data ranke d the USA 16th in total aquaculture production in 2016 just below Ecuador , producing just 0.4 MMT; however, the USA produces high value products worth ~$1.2 billion or ~$3,100/T. The USA imports more seafood than any other nation, spending an estimated $20.5 billion in 2016. Taking th is high value estimate, it could tak e only ~7 MMT of new offshore aquaculture production to equal the total value of all US imports and virtually erase the horrendous US seafood trade deficit. Development US offshore aquaculture w ould turn the USA into one of the world's largest mariculture nations. Why is there no offshore aquaculture combined with energy production in the USA? We conclude that the economic and legal/regulatory structures of offshore oil/gas leasing systems have not and will not change, and that offshore aquaculture will not develop to any significant degree in the fossil fuel industry or in their lease areas. This is conclusion should be nothing new to anyone. However, what is new is the coming "blue wave" of offshore windpower, especially in the N E USA (~17 GW by 2035). I n De . 2018 a "frenzied two-day auction " was run by the Bureau of Ocean Energy Management for windpower development sites off Massachusetts. Winn ers were experienced European companies who paid over $400 mil for just three lease areas. How can offshore aquaculture develop rapidly in windpower lease sites? The experiences of Deepwater Wind who installed the first US offshore wind energy facility (~30 MW off Block Island , RI) are relevant especially in needs for accelerated offshore engineering capabilities , state-based port upgrades and manufacturing enhancements , and especially for Jones Act compliant vessel s to eliminate imports of major parts and vessels from Europe. But the business case has to be combined with thoughtful, respectful, participatory, transdisciplinary , University/ Sea Grant extension processes that have the ability to convene hundreds of stakeholders over an extended time period to meet the multiple requests for information. The Rhode Island experience points the way forward not only to secure the business case but also for enh anced federal-state investments in offshore aquaculture in the windpower leases.
