Members include many of the UK's major retailers and seafood businesses, alongside retail and industry trade bodies. The UK non-departmental public body Seafish acts as the SEA Alliance's Secretariat, and has been closely involved in the initiative's development since 2018.
In May 2021, the SEA Alliance was awarded a grant from the David and Lucile Packard Foundation to scale up its activities and recruit a dedicated member of staff.
Andy Hickman, formerly Tesco's Head of Human Rights, was appointed Head of the SEA Alliance in January 2022. He said:
I am very excited about this unique opportunity to work with Seafish and participating companies to take forward the SEA Alliance’s work to tackle human rights issues in the global seafood sector. By working to better understand human rights issues in our source fisheries, and building effective networks across the seafood industry and civil society, I believe the SEA Alliance can be a catalyst for positive change. Ensuring that human rights are respected in seafood supply chains is critical to ensuring an ethical and sustainable seafood supply chain into the future.
