A farm shifts from carnivorous species to herbivorous species (e.g., from salmon to carp); which sustainability outcome is most likely?
A
Lower reliance on fishmeal and improved trophic efficiency, often reducing pressure on wild forage fisheries and decreasing feed-related environmental impacts.
B
Higher reliance on fishmeal because herbivores require more animal protein, increasing demand for wild-caught forage fish and bycatch rates.
C
Elimination of nutrient pollution because herbivores do not excrete nitrogen or phosphorus, preventing eutrophication in any culture system.
D
Guaranteed reduction in land-use impacts because herbivorous feeds cannot include crops, so deforestation and fertilizer use are impossible.
