Here we send our paper entitled ;

Grafting of the seaweed Kappaphycus alvarezii (Rhodophyta, Gigartinales) in SE-Sulawesi, Indonesia  published in Aquaculture research (

DOI: 10.1111/are.14972)

i will show also our recent findings of the seedlings using grafting method  after one-year cultivation done in North Buton regency, SE Sulawesi, Indonesia

What conditions are missing in the most commonly cultivars strains which disable them from either sexual or asexual reproduction  through sporogenesis? Is it their reproductive structures are entirely absent or do they sometimes form during cultivation?

Thanks for sharing the marvelous and important work that you and your group are doing Dr. Roleda. This type of work is EXACTLY the type of work that we hope can be networked ASEAN-wide through the collaboration tentatively called BeBiNet in a presentation I made at this TPCD workshop. Scale-up and involvement by farmers in nursery systems is a further step and I am interested in your thoughts about that.

Thank you for sharing your works and pieces of knowledge. I wonder how does the induction of germination and sporulation of the seaweed is being done? How long does seaweed takes to finish its life cycle?
