Wild fish consumption can balance nutrient retention in farmed | ResearchBunny

Index

Abstract

This study investigates the nutrient retention efficiency in salmon farming using wild fish as aquafeeds and explores scenarios to maximize nutrient-rich food for humans. Analysis of Norwegian salmon farms reveals that wild fish used for feed (anchovies, mackerel) had higher yields of six out of nine dietary nutrients compared to farmed salmon. Reallocating one-third of food-grade wild feed fish to direct human consumption would increase seafood production while retaining by-products for aquafeeds, optimizing marine resource utilization.
