Environmentally Responsible Aquaculture
Seaweeds absorb and capture dissolved inorganic waste and product oxygen through photosynthesis.
Deposit feeders, like lobsters, sea cucumbers, and sea urc hins, feed on the the excess fish feed and the waste from the fish and mussel systems to recycle waster and minimize sea floor impacts
Suspension feeders, like mussels and other shellfish, recycle organic nutrients and excrete dissolved inorganic waste.
