Tree-like cultivation system improves biomass production of the algae “yuyo” Chondracanthus chamissoi
Schema of the tree-line system (TLS) with 20 culture substrates inoculated with Chondracanthus chamissoi fragments installed in the sea. (a) Buoy, for the stability of the system. (b) Main line (7 mm polypropylene rope) 2 m long. (c) Substrates inoculated with C. chamissoi distributed opposite each other. (d) Anchoring made from a 50 × 50 cm fishing net filled with rocks. (e) Sea area covered (4 m2) for each TLS. Source: Arbaiza et al., (2025); Journal of the World Aquaculture Society, 56(2), e70007.
