Abalone feed on plants, mainly kelp or seaweed, so no fish is required for feed. There is no fishing pressure to wild stock.
Abalone farms generate low rates of discharge. Onshore land-based tank systems will not create serious habitat alteration. Abalone may suffer from parasites, but effects are limited. Chemicals are used but will be diluted to a level that will have low impact on the environment.
In South Africa, the aquaculture is controlled by the Department of Agriculture, Forestry and Fisheries (DAFF). The establishment of the African Live Molluscan Shellfish Monitoring and Control Programme, covers the use of chemicals, water pollution, disease management and monitoring. The country’s overall aquaculture management is partly effective.
