Novel observations of benthic enrichment in contrasting flow regimes with implications for marine farm monitoring and management

► Reveals a-typical environmental responses along spatial gradients, due to flow. ► Very high abundances and biomass were evident when organic accumulation was not. ► Moderate-to-high species richness maintained under highly enriched conditions. ► Greater resilience to organic waste streams attributed to biological processes. ► Ramifications for fish farm siting and production and for environmental management.
