  • Advantages of Using Herbivores in Aquaculture
    • Higher energy efficiencies - at a lower trophic level (shorter food chain)
    • Lower food inputs - no fishmeal
    • Higher productivity per unit area
    • Plant food inedible to humans can be used
    • Less fishing impacts - no need to get fishmeal
