the "tie-tie method" for the mechanization of Kappaphycus (a genus of red algae commonly known as cottonii and seaweed) is not a widely known or established term in the scientific literature or aquaculture community. It is possible that the term or method may have emerged or gained recognition after my knowledge cutoff date.
The cultivation of Kappaphycus seaweed typically involves the process of "farming" or "mariculture." The standard practices for Kappaphycus farming include the use of floating rafts or lines in the sea where the seaweed is attached to these structures for growth and harvesting.
If the tie-tie method has been developed or utilized more recently, it may involve a specific technique or variation in the way Kappaphycus is cultivated or mechanized. To find the most up-to-date and accurate information on this topic, I recommend conducting a search in academic journals, aquaculture publications, and other reputable sources for any new developments or practices related to the mechanization of Kappaphycus using the tie-tie method. Additionally, reaching out to experts or researchers in the field of seaweed aquaculture could provide valuable insights into this specific method.
