This study was conducted to analyze the weight of Kappaphycus alvarezzi and Sargassum polycystum mixcultured at different planting distances. Statistical analyses showed that planting distance was significantly influence the growth of K.alvarezzi and S. polycystum. Difference in weight gain between both species be due to the difference in their morphology which affect water motion and nutrient uptake. Higher weight gain of S. polycycstum was obtained at wider planting distance (35 cm). High , and at 30 cm for K.alvarezii. K.alvarezii was more susceptible to competition for the environmental factors compared to S. polycycstum. Higher weight gain of K.alvarezii obtained in this mix-culture with S.polycystum compared to the K.alvarezii which was singly cultured by previously several workers.
