P.  aWhy is algaculture still incipient in Brazil?h[electronic resource]  c2016  aMacroalgae represent 26 % of the global production of cultivated organisms, with Gracilaria spp. representing 12 % of that production; Eucheuma spp. and Kappaphycus alvarezii account for 34 % of world?s algae production. Despite the potential for cultivating seaweed in Brazil, and with its more than 8000 km of coastline, there is neither marine algaculture nor detailed knowledge even among aquaculture farmers concerning the utility of algae in agriculture, industry, and gastronomy, with the result that algaculture represents only the smallest fraction of national aquaculture production. The main cultivated species of seaweed sold in Brazil include the exotic K. alvarezii and native species of Gracilaria that are grown on small scales and do not meet national industrial demands, which must be supplemented by imports. We discuss Brazilian algaculture here, pointing out some of the problems that restrict commercial production of algae in that country and offer solutions that could be shared with other nations.  aAlgaculture legislation  aAlgaculture politics  aBrazilian algaculture  aBuilding capacity  aEnvironmental risks1 aCASTELAR, B.1 aSANTOS, A.
