From Feed to Food: Using Nutritional Life Cycle Assessment to Evaluate Sustainability and Consumer Nutrition Outcomes of Aquaculture

Abstract

Aquaculture feeds are a key determinant of both the sustainability and nutritional quality of farmed seafood, influencing production efficiency, environmental impacts, and the nutrients ultimately delivered to consumers. As consumer demand grows for foods that are both nutritious and environmentally responsible, producers and retailers face increasing pressure to demonstrate product value through nutritional profiling and environmental reporting. Understanding how feed choices affect these outcomes is, therefore, critical for developing aquaculture systems that meet both market and sustainability objectives. Seafood occupies a unique position among animal-source foods, often delivering high nutritional value with comparatively low environmental impacts.

Nutritional Life Cycle Assessment (n-LCA) is an emerging approach that integrates nutritional outcomes with environmental performance, providing a framework to evaluate the broader consequences of feed and production decisions.

This presentation explores the application of n-LCA within integrated agriculture–aquaculture systems in Bangladesh to assess the environmental, nutritional, and economic implications of different production approaches. Results indicate that locally adapted tilapia strains reared in well-managed intensive systems and fed formulated pelleted diets can generate strong nutritional benefits and economic returns while maintaining favourable environmental performance.
