Are there any known species of edible seaweed that can be cultivated in aquaponics in order to enrich the water with oxygen? What are their needs in nutrients? Could they be cultivated along side with fish and tomatoes for example?
Hi Orfeas, You want a species of seaweed for aquaponics. So no tomatoes. you can use species of Ulva a green sea vegetable which can enrich dissolved oxygen in seawater under light. Add nutrient mix as suggested by Walne or Convoy once in a week.
gracilaria, ulva can increase oxygen. but you can also try the other species and has strong adaptability. I tried to maintain Halimeda and have the adaptability to a very good living. but I have not studied the oxygen produced. gracilaria have excellent adaptability to.
