Many shellfishes are filter feeders that remove waterborne particles, including phytoplankton. Abalone, on the other hand, feed on
macro-algae (kelp). Kelp use water column nutrients and sunlight
to produce growth and oxygen. Sustainable harvesting or farming
of kelp can be considered as a potential benefit to mitigate excessive
nutrient levels as part of a broad coastal management plan . In the process, two valuable products can be developed,
where kelp grown in nutrient rich waters can have environmental
benefits and then be converted to high-value abalone meat when
used as feed. Furthermore, abalone meat is considered a delicacy
with a high market value.
