Public bidding documents of aquaculture sites elaborated from 2011 to 2013 provide information about the capacity of mariculture production in this state, which, together with the productivity indicators of Kappaphycus alvarezii farming in Santa Catarina, supply the necessary basic data for evaluation of the potentiality of three seaweed farming systems: monoculture of seaweed K. alvarezii (S1), biculture of K.alvarezii with oyster Crassotrea gigas (S2) and biculture of K. alvarezii with the mussel Perna perna (S3). Economic, financial and social evaluations conducted based on in these three systems show that among 720 aquaculture areas established in the state over 12 sites, 85% are designed to producers counting 969.45 ha, with an average of 1.57 ha per farmer. The seaweed production by the S1 system ammounts to 24,19 t ha-1 yr-1 while by S2 and S3, the outcome is 13,61 t ha-1 yr-1, in addition to oyster (41,667 t ha-1 yr-1) and mussels (40,00 t ha-1 yr-1) production, respectively. All systems consider 3 annual production cycles of seaweed. Economic, financial and social indicators show that these 3 systems are profitable. However, the S2 shows 3 times higher profit than the others, in all aspects.  acottonii  afarming systems  aintegrated cultivation  amussels  aPacific oyster  apayback  aproduction costs1 aDOROW, R.1 aARAUJO, L.
