“…We considered the possibility of nitrogen limitation in our study, but do not believe it was a factor. Berglund (1969) reported that optimal growth of U. linza occurred at 14 μM DIN and that growth was inhibited at 21 μM DIN; Kamer and Fong (2001) found that the growth of U. cf. intestinalis could respond positively up to 80 μM DIN.…”

a b s t r a c t a r t i c l e i n f oAnnually recurrent green-tides in the Yellow Sea have been shown to result from direct disposal into the sea of fouling Ulva from Pyropia aquaculture. The role abiotic factors play in Ulva biomass accumulation on rafts was studied to find ways to mitigate this problem. Dissolved inorganic nitrogen (DIN) was very high at all sites, but the highest Ulva biomass was associated with the lowest DIN and anthropogenic N. Under luxuriant background nutrient conditions, variability in temperature and periods of emersion, rather than pH, light and salinity determined Ulva biomass. Two dominant species of Ulva displayed differing tolerances to temperature and desiccation which helped explain why Ulva prolifera dominates floating green-tides. Rather than trying to mitigate greentides only by reducing nutrient pollution, an earlier harvest of Pyropia in southern Jiangsu Province especially before temperatures increase greatly above 10°C during April, could reduce the biomass of U. prolifera disposed from rafts.Crown

“…The cultivation media was renewed once every two days (Pang et al, 2009). While previous studies have been conducted on the nutrient requirements of macroalgal, such as Lamina saccharina, Enteromorpha intestinalis (Kamer and Fong, 2001), and S. baccularia (Schaffelke and Klumpp 1998) the cultivation media was changed either weekly or once every two weeks. For instance, the red algae Gracilaria tikvahiae can uptake ammonium-nitrogen relatively quickly and can increase the nitrogen content in the tissue within 8 h or less (Ryther et al, 1981).…”

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 15.35 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 0.42 and 1.70 (% per day). Aquasol is recommended as a nutrient supplement to enhance the specific growth rate of S. spinuligerum.

“…The specific role of alternative pathways for nitrogen removal was also not studied in this experiment. Higher concentrations of nitrogen and phosphorus will be deposited in the tissue [23] but the excess nutrients in water do not necessarily lead to their high concentrations in tissues, even luxuriant consumption phenomena observed in seaweed [24]. In addition to that, the nutrient uptake efficiency sometimes was observed low and nutrient concentration remains high in the effluents.…”

Aquaculture industry is often generating waste that negatively impact to the environment. These wastes are rich in nutrients. Seaweed can utilize these waste nutrients. This experiment was conducted in a flow-through system (FTS) and a recirculation system (RS) in land-based integrated multi-trophic aquaculture module using seaweed Kappaphycus alvarezii as one of the components. The aim was to access the efficiency of the removal of nutrients in the integrated culture. Kappaphycus alvarezii was stocked at the density of 1 kg/tank in the rectangular plastic tank with 500 L of seawater. The waste generated from integrated multi-trophic aquaculture tanks was directed towards K. alvarezii culture tank. Water samples from inlet, outlet and inside of the culture tanks were drawn to determine the nutrients, namely, total nitrogen (mg/L) and total phosphorus (mg/L). Total nitrogen and total phosphorus in the seaweed sample and from the sediment of culture tanks were also analyzed. The total nitrogen amounting to 59.5% and 61.6% nitrogen was taken up by K. alvarezii in FTS and RS culture tank, respectively. The phosphorus showed the highest deposition of 61.1% and 31.6% in the sediment of in FTS and RS culture tanks respectively, whereas only 5.5% and 3.4% of phosphorus were taken up by K. alvarezii from FTS and RS culture tanks, respectively. The percentage of nitrogen remained in water was comparatively higher by 14.2% and 27.5% than phosphorus by 8.3% and 23.0% in water of both FTS and RS culture tanks, respectively. These results indicated that this species seaweed is efficient in the removal of nitrogen from both FTS and RS culture tank.
