The highest growth rate (70.3 ± 3.4 μm/day in shell length; 23.6 ± 2.4 mg/day in weight), highest survival rate (95.6 ± 1.6%), and the best food conversion rate (3.3 ± 0.5) were obtained with the red alga, G. tenuistipitata. The brown alga, P. minor, gave the lowest growth (2.1 ± 3.0 μm/day in shell length; -0.3 ± 0.3 mg/day in weight) and survival (7.8 ± 1.6%) rates. The proximate composition of these nine species of algae was determined to suggest correlation with growth rates. G. tenuistipitata was found to have the highest content of protein and carbohydrate.Mahidol UniversityAgricultural and Biological SciencesConference PaperSCOPUS
