The research project was conducted to determine the growth performance of seaweed in land-based tank culture system for research purposes. Two tank culture systems were completed using circular and raceway tanks and three cultures of 40- days period were performed in each system. Red seaweeds, Kappaphycus a/varezii and Kappaphycus striatum were selected and cultivated in each tank culture system. Using circular tank, the maximum daily growth rate was recorded in tank with lowest seaweed density of 0.96 g L·1 on K. striatum (2.00±0.03% day"1 ) and K. alvarezii (1.46±0.06% day"1). In the second part of study, raceway tank was used and the results indicated that both Kappaphycus succeeded to grow with the highest average daily growth rate of 2.96±0.02% day"1 for K. striatum and 2.13±0.03% day-1 for K. alvarezii. Kappaphycus striatum was found to grow well in both system compared to K. alvarezi. The results also showed that the biochemical composition of both tank cultured Kappaphycus were comparable with the open sea culture where the average percentage of crude protein, crude fibre and carrageenan content of the Kappaphycus cultured in the tank were fall within the range mentioned in the previous literature. Thus, tank culture system did not significantly affect the biochemical composition of the Kappaphycus. In conclusion, the success in cultivating Kappaphycus using circular and raceway tank indicated that seaweeds are highly potential to be cultivated in land-based facilities comparable with the open sea culture seaweeds. These findings are significant to provide a baseline data and facilitate seaweed research area especially for high quality sustainable seaweed seed production in the future.
