WWW.WAS.ORG • WORLD AQUACULTURE • MARCH 2026 61 Policymakers hold the key to removing one of the most persistent barriers to aquaculture expansion in the US: complex and often prohibitive permitting requirements (Engle et al., 2020; Hurley et al., 2024). Easing this regulatory burden is vital to facilitate the shift from synthetic fertilizer dependency to biologically integrated, zero-discharge farming systems like IAAS — thereby accelerating the adoption of regenerative agriculture and climate-resilient food production.
