growing seaweed aquaponics

Aquaponics is indoor farming using nutrient rich water from fish raised in recirculating aquaculture systems (RAS) as fertilizer for growing plants in a soilless hydroponic medium. It has many uses, including food, cosmetics and fertiliser. We have over 10 years of experience working in aquaponics and our goal is to help you get your aquaponics … Over time, the system will stabilize itself, but when systems are young, algae can be very frustrating. Materials you will need: 14 gallon fish […] Seaweed is a large variety of algae that grows in both fresh and salt water. A very interesting concept, 3D Ocean farming is like vertical farming in the sea. From building a backyard system to designing a commercial system we’re here to help you succeed in aquaponics. The waste builds up over time, which is normally quite toxic to the fish. Seaweed can grow through the winter, so seaweed farming is a complement to most shellfish farming, which takes place in warmer months. Oct 29, 2014 – Seaweed is a large variety of algae that grows in both fresh and salt water. Aquaponics is a sustainable form of agriculture that combines RAS and hydroponics to reduce the footprint of agriculture. Exactly this! I wondered if it would be possible though, to create some indoors setup where you could rear saltwater fish and use the water for aquaponicly growing kelp that’s lying down in … It is possible to grow your own seaweed at home in a large aquarium using salt water you make on the stove. Aquaponics is a system of growing plants and fish together to conserve water and eliminate the need for chemical fertilizers to aid plant growth. The basic setup of aquaponics systems is that plants grow of top of water, where one or more fish live. Some seaweeds are edible and can be used in plant fertilizer or medicines. Saltwater aquaponics for purely saltwater crops So let’s take this even a step further. ; Portable Farms® Aquaponics Systems can feed your family or your community all the table vegetables and protein necessary to sustain excellent health FOREVER. Aquaponic gardening is an organic system in which fish and plants are grown together. Seaweed is a type of algae commonly found growing in the ocean. It is possible to grow your own seaweed at home in a large aquarium using salt water you make on the stove. Aquaponics How to build the cheapest and easiest setup for aquaponics! No longer will you need multiple pumps and reservoirs, the whole system is an enclosed system much like nature. One of the best plants to grow in aquaponics is the Thai Sweet Basil. Rather than building and experimenting with growing traditional vegetable crops in saltwater, why not grow saltwater aquatic plants with commercial value in these systems. The entire project cost only $35. Please realize that this is not an entire listing, as there are over 300 different types of vegetables that have been grown in aquaponics … It is possible to grow your own seaweed at home in a large aquarium using salt water you make on the stove. Some seaweeds are edible and can be used in plant fertilizer or medicines. In food, it is often dried out and eaten plain or as a wrapping for sushi. However in this system, the plants growing on top dangle their roots into the water, and absorb the waste. Leave the aquarium in a sunny spot so the seaweed will grow properly. Aquaponics, growing fish and vegetables in your own backyard. I wondered if it would be possible though, to create some indoors setup where you could rear saltwater fish and use the water for aquaponicly growing kelp that’s lying down in … Basil is a member of the mint family, which explains its ability to grow rapidly. It is compatible with aquaponics systems and grows quite well in that environment.

Saltwater Aquaponics/Bioponics with Seaweed as a crop

My wife and I love seaweed. We used to go to this Korean store down the street and buy fresh seaweed to put in soups and salads. Unfortunately, they’ve stopped selling it. I don’t know why, I could guess because of the Fukashima issues with contamination of their waters or maybe it’s just not selling well enough. Either way, we found that getting fresh seaweed is expensive. The only online stores that sell it are in Maine or California and at ridiculous prices. So we decided that maybe we can try to do saltwater aquaponics/bioponics.

I know others have done this, but unfortunately, they haven’t given out any knowledge to help others (that I can find).

It is my hope that because there is so little information available on how to do this, that we will attempt to do the research and testing to see how this can be accomplished and publish our findings to the world so others can duplicate our efforts without the trials and errors that we already went through.

We are also hoping that others will do this or already are doing this and can give us some advise or pointers so we don’t make every mistake in the book. If anyone is knowledgeable on seaweeds and their growth habits, that would also be very helpful if you would give some input.

So this will be our setup.

Everything will be grown in our greenhouse in the 7a climate in the US.

A 55 gallon plastic white drum (white so it doesn’t get too warm). We will cut the top 1/3 part off and use that as the “grow bed” and the bottom 2/3 part as the reservoir/nutrient tank. We thought about using saltwater fish but since I am completely ignorant on how to raise saltwater fish, we thought it best to use aged urine as the main nutrient source.

It will be a deep water continuous flow (not ebb and flow) with a small 12w 200 gph water pump, pumping from the bottom tank to the top and it will flow down through a 3/4″ PVC pipe back to the bottom tank again. The top bed will have large rocks for the seaweed to anchor itself to it.

For the choice of seaweed, we think Dulse and Sea Lettuce would be best for consumption.

We do not know yet whether these two different types of seaweed require different environments (salinity, ammonia levels, nitrification, etc.) so we may need to build two systems to sustain each one separately.

I have read that Sea Lettuce can absorb straight ammonia and nitrification is not necessary for it’s growth. I want to test that by not having much media for nitrification and using aged urine as the primary nutrient source. The only other input would be Aquarium/Ocean Salt (to maintain the proper salinity that seaweed requires) that I will purchase online. I will be measuring salinity with a cheap hydrometer.

I am currently negotiating with some seaweed sellers in Maine for a piece of Dulse and Sea Lettuce and am awaiting a quote.

Feel free to comment or discuss.

Dr. Edoardo Pantanella PhD,University of Tuscia, Viterbo, Italy was doing some research on saline aquaponics in Tiawan. I talked with him this past June in Stevens Point, Wisconsin. He has had some success on 10% saline systems were he was experimenting with quinos. Not sure how to get ahold of him, but he probably has more info on this subject, then anyone I know.

You will need everything that you would put on a reef tank for an aquarium. In salt water you don’t want lose organic proteins in the water, so you need a protein skimmer aside from normal aquaponic setup. I would also suggest a calcium reactor to make keeping your calcium and magnesium easier to control on that large of a system and a UV sterilizer to control algae. Also remember that some algaes release something called allelopathy which is basically toxins to kill there neighbors that must be neutralized occasionally with something like chemipure or purigen. What questions do you have specifically about your proposed system. This has peaked my interested and i can very much help you.

I plan to build commerical saltwater aquaponics in south NJ, did you already run such system successfully?
