tailieunhanh - Effect of nutrient media and initial biomass on growth rate and nutrient uptake of Sargassum spinuligerum (Sargassaceae, Phaeophyta)

The Sargassum species are prospective candidates for marine culture, but there are a limited number of reports on their nutrient requirements and optimum initial stocking biomass, and nothing is published for Sargassum spinuligerum. | Turkish Journal of Biology Turk J Biol (2017) 41: 808-815 © TÜBİTAK doi: Research Article Effect of nutrient media and initial biomass on growth rate and nutrient uptake of Sargassum spinuligerum (Sargassaceae, Phaeophyta) 1,2, 1 1 1,2 Tin Cong HOANG *, Ravi FOTEDAR , Michael O’LEARY Curtin Aquatic Research Laboratories, Faculty of Science and Engineering, Curtin University, Perth, WA, Australia 2 Faculty of Environmental Science, University of Sciences, Hue University, Hue City, Thua Thien Hue, Vietnam 3 Australian Institute of Marine Science, UWA Oceans Institute, Perth, WA, Australia Received: Accepted/Published Online: Final Version: Abstract: The Sargassum species are prospective candidates for marine culture, but there are a limited number of reports on their nutrient requirements and optimum initial stocking biomass, and nothing is published for Sargassum spinuligerum. This study investigated the effects of three commercially available fertilizers (Hortico, Seasol, and Aquasol) and four initial stocking biomass levels of S. spinuligerum on the growth rate and nutrient uptake capacities for 7 weeks. The results showed that S. spinuligerum could be grown under outdoor conditions with the optimum initial stocking biomass of g per 113 L. The different commercial fertilizers significantly influenced the specific growth rate and nutrient uptake rate of S. spinuligerum. Aquasol resulted in a higher specific growth rate than the other commercial fertilizers, with the relative growth rate fluctuating between and (% per day). Aquasol is recommended as a nutrient supplement to enhance the specific growth rate of S. spinuligerum. Key words: Sargassum spinuligerum, marine biomass, nutrients, specific growth rate, nutrient uptake rate 1. Introduction The genus Sargassum belongs to the family Sargassaceae (Phaeophyta), and is one of the most diverse .
