System-specific aquaculture annual growth rates can mitigate the trilemma of production, pollution and carbon dioxide emissions in China

Abstract

Paper summary generated by OpenAI: This study addresses the trilemma of enhancing aquaculture production while minimizing nutrient discharges and carbon dioxide emissions in China. By evaluating the growth trajectories and ecological footprints of various aquaculture systems, the authors propose a two-step approach that includes ecological transformation and the adoption of green aquaculture practices. Adjusting the annual growth rates of six out of nine aquaculture systems could lead to significant reductions in energy use, nitrogen discharge, land use, and freshwater consumption by 2050. The findings suggest that, despite a projected increase in total CO2 emissions from aquaculture, the overall impact can be mitigated with strategic adjustments, providing a blueprint for sustainable aquaculture development in the post-carbon neutrality era.
