Effect of Salinity on the Growth and Biochemical Composition of Sargassum thunbergii and Gracilaria verrucosa

Abstract:

The effect of salinity (10,20,30,40,50) on the growth and biochemical composition of Sargassum thunbergii and Gracilaria verrucosa were investigated under the laboratory conditions, the results showed that: specific growth rate and chlorophyll a of Sargassum thunbergii and Gracilaria verrucosa were first increased and then decreased with the increase of salinity, the carotenoids content of Sargassum thunbergii in 10 salinity group and Gracilaria verrucosa in 40 salinity group were the maximum respectively. After comprehensive analysis, in the 10-50 salinity range, The optimal salinity for the growth of G. verrucosa and S. thunbergii were 20 and 30 respectively.
