Summary

Feed: Feed used in abalone culture is considered quite sustainable as abalone are herbivores consuming algae and requiring only supplemental feeding. When algae is harvested from the wild, it is generally well regulated, with harvested biomass regrowing quickly.

Effluent: Though effluent from bottom culture is discharged into the ocean it is low in nitrogen and is not considered to have adverse effects on the surrounding environment.

• Bottom Culture: Enclosed Bottom Culture

Summary

Feed: Feed used in abalone culture is considered quite sustainable as abalone are herbivores consuming algae and requiring only supplemental feeding. When algae is harvested from the wild, it is generally well regulated, with harvested biomass regrowing quickly.

Source of Stock: Abalone farms generally source stock from facilities that produce abalone seed stock. The broodstock for these operations sometimes comes from wild populations, or may be hybrids that are specifically cultured for aquaculture. At present, collection of broodstock or larvae is not considered to have significant negative impacts on wild populations.
