  • Kelp (sea weed)

    Kelp for animal feed as a first step to generate revenue:

    I live in Southern-California. I have a boat. The boat is on a trailer. The trailer with the boat is in my front yard.
    I also have a back yard. Boat launching possibilities, with access to the Pacific ocean, is about 60 miles from my house.
    There is also a house on my yard. I live in the house, and I own it.

    I also have a van, so I can pull the trailer, with the boat on it, to a launching ramp. Registrations are current, and all are in
    good working order. No HOA (housing association), where I live.

    My opinion is, that the least regulated revenue generating activity would be harvesting kelp and processing it to animal feed.
    The harvesting, first, would be in California state waters of the Pacific ocean, with a California state kelp harvesting license,
    from open kelp fields. I would dry the kelp in my back yard and process it to animal feed pellets. I would bag it in 50 lb bags
    and sell it. This could be a first step revenue generating activity for the next steps.

    The final step could be an artificial ocean ranch 200 NM from shore with floating facilities to process products and house people.
    Each step, in between, might take some time. The first step might take some time too.

    Any cooperation is appreciated. The business model would be a co-op style one.

        More about the 'plans'.
        One of the phase would be cultivation of kelp for harvest. This could be in California state waters (within 3 NM (NM=nautical mile)) from shores.
        Or it could be in US federal waters (outside of state waters of 3 NM, and within 12 NM from shore). Or it could be outside of US territorial waters,
        and still within US EEZ . Further than 12 NM and within 200 NM from shore.

        The Pacific ocean gets very deep very quickly . Kelp grows from about 90' about 30 meters under surface. In deeper water kelp does not grow.
        There is kelp in deeper waters too, but it is in a floating, drifting state called; kelp wrack. I think, kelp could be anchored in deep water to sub surface buoys.
        These sub surface buoys could be anchored with mooring lines to anchors. The anchors would be on or in the sea floor. It would be necessary to
        use long mooring lines. One of the possibility is to make mooring lines from recycled waste car tires, and take the recycling fee for the tires ($1.75/tire).
        This could generate revenue up front.

        (There has been a long term study conducted on tires immersed in sea water.
        Publication # 432-96-029, May 1996
        "There has been a long term study conducted on tires immersed in sea water. The study concluded that after 42 years tires constructed of polyisoprene
        and immersed at a depth of 80 feet showed very little degradation. "

        (Sustainable Re-use of Tyres in Port, Coastal and River Engineering Guidance for planning, implementation and maintenance )

        Tire structures and mooring lines can be made as it is shown in

          Some time back there was an experiment with kelp where they grew it on PVC pipe I think. Nutrient rich water was pumped from below that made the kelp grow very well. The problem they had is the kelp was torn off the pipes in storms. I think this could be overcome with nets.


          • #6
            Yes, the torn off kelp is a problem. Some solution is necessary. Nets are good idea. It might work well.

              It might also be possible to use some sort of mesh barrier that will allow water to pass but slow it down enough so as not to harm the kelp. What exactly we might use that would be affordable I don't know. Flat ribbons of woven plastic or some such thing might have an effect. We can experiment. We might also try simply breeding kelp with a stronger ability to attach. We could also keep the kelp short by harvesting when ever it reaches a certain height so that there is less surface exposed to the force of storms. This might allow it to stay attached as well.

                As a first effort I will go find the kelp beds. I have a boat on a trailer.

                So, kelp grows back. Kelp harvest is like mowing the grass in the yard. The grass is not uprooted, and the grass is not destroyed.
                There is a steady supply of cut grass during grow season. Same way with the kelp. Only the top of the kelp is cut, and it grows back.
                It grows back very fast, sometimes a foot a day. Kelp can grow from 80' depth to surface, and only the top part of the kelp is cut that is
                about 3' under the surface. The rest of the kelp that is deeper than 3' is not cut, and left there to grow back to surface.

                  In an open ocean condition, where the kelp would be grown from subsurface buoys. The buoys would be anchored to the seabed by mooring lines.
                  The kelp would be grown to surface from the buoys. When kelp is cut and it is not used it could be ground and let sink beyond the pycnocline line.
                  At that point the kelp might not come back from that for thousands of years. Can I get carbon credit for that from the Paris convention?
                  Preferably credits would be paid to me in $US. Or shell I just dream on?

                  Kelp would be cut only to 3' under surface. It would grow back to surface from the remaining 77' some feet of it left in the water.
                  It would grow back to surface. It can be cut again and again.

                      Sub surface buoy could look something like this:

                          Where I got with kelp:

                          To start with kelp; it would be in California state waters. That requires a commercial license to harvest kelp.
                          It also requires a commercially licensed boat. The harvested kelp has to be landed somewhere at a port.

                          Processing kelp for animal fee is not as unregulated as it used to be. There is a Food Safety Modernization Act,
                          and the FDA (federal Food and Drug Administration) is involved. There will have to be, probably a state tax ID, and
                          product liability insurance.

                          And all that probably can be done. It is just a slow process for me. Any cooperation would be appreciated. And I do not
                          mind doing it alone.

                          All this would be for financing ocean activity, and moving further from shore.

                          First it would be kelp harvest from open fields in state waters. Right now it is cold and rainy. I guess agricultural workers
                          are familiar with the seasonal nature of the work. It is a bit new to me.

                          I talked to a few people about ocean farming. It is a new industry. The idea of regenerative work in the ocean is not so well
                          understood by people who do commercial fishing. It would be an idea like "... taking care of the ocean pastures ..."
                          Something similar what Russ George advocates at

                            There could be one more difficulties with kelp for animal feed: iodine content.
                            Iodine is volatile. Heating the kelp might lower the iodine content.
                            Autoclaving might accomplish a few tasks: releasing the pressure to get rid of all the moisture,
                            and lower the iodine content, and sterilize the kelp. It might be easier to digest. But it is an extra expense.
                            I hope to be able to break even, and later make profit with it.

                            Is there anyone interested? Anyone has a commercially registered boat? If not, I'll do it all by myself.

                              California gets lots of sun how hot do you need to cook off Iodine? A Fresnel lens and a refractory box to keep in heat might work to do the Iodine, sterilization and excess water problems.
                     Here is a demo of the lens

                            This spar buoy house concept, a few years old, assumes that kelp will be grown on the spar at an appropriate depth.
                            This is not my project, and unfortunately I did not save any details of the entity that published it.Click image for larger version  Name:	spar_buoy_house.jpg Views:	21 Size:	44.1 KB ID:	380

                              Let me know where you plan to put it. I will come to look at it if it is close to me.
