Micronutrient composition, feed requirements and food outputs of alternative production scenarios (IMAGE)
Caption
Four production scenarios are presented in (a): I is farmed salmon fed on fishmeal and fish oil (FMFO) from wild-caught fish and trimmings (business-as-usual); II is salmon produced only from trimmings, with the spare edible wild-caught fish supplied directly to humans; III is trimmings-only salmon with equal portions of wild-caught fish and mussels; IV is trimmings-only salmon with equal portions of wild-caught fish and carp. In (b) the micronutrient concentration of Scenarios II—IV are shown relative to Scenario I (red dashed line). In (c) changes to seafood production required for each scenario are shown by the spare volume of wild-caught fish (relative to wild-caught fish in FMFO, Fig 1B of the manuscript), the fishmeal required for production, and the total volume of seafood produced corrected for edible portion sizes.
