A side-by-side comparison of conventional and insect-based aquafeed ingredients has found that insect meals and oils come with a larger carbon footprint and require more energy to produce than marine ingredients – but this discrepancy might be short-lived.

Results from an integrated multi-trophic aquaculture (IMTA) project with sea cucumbers and marine finfish show that the system is feasible, but practitioners need to refine their designs to ensure the sea cucumbers thrive.
