“…(2,6%). The high concentrations of ammonium and nitrate in water trigger an increase in the accumulation of total dissolved protein [18]. Therefore the nitrogen content in the thallus of Hypnea Aspera also increased, even though not all absorbed nutrients were assimilated and stored.…”

This research aims to determine the performance and nutrient removal effectivity of seaweeds species, namely Ulva fasciata., Sargassum illicifolium, Gelidium sp., and Dictyota sp. as a biofilter in hybrid grouper aquaculture wastewater at low salinity (14-17 ppt). This study used a Completely Randomized Design with 3 replications. The statistical analysis was carried out by Analysis of Variance continued with the Least Significance Difference test, and the Kruskal-Walis test with the Mann-Whitney analysis, and T-test with a confidence level of 95%. The concentrations of ammonia, nitrate, phosphate, and water quality parameters were observed every 4 days. The seaweeds uptake of N and P in water, and Specific Growth Rate were also observed. The results showed that U. fasciata was able to reduce ammonia by 75.95% and nitrate by 79.53%, which were the highest compared to other treatments, while Dictyota sp. was able to reduce the highest phosphate by 87.5% for 20 days. The highest SGR was achieved by U. fasciata at 1.91 %day-1. The highest N content uptake by seaweeds was 104.4%, and the total P of 182.3% occurred in U. fasciata. Overall, U. fasciata has the highest performance and effectiveness as a biofilter that is able to reduce nutrient waste in low-salinity from grouper aquaculture, for re-circulation or before being discharged into the environment to reduce eutrophication and harmful Algal Blooms (HABs) in aquatic environment. The highest growth rate of U. fasciata can be used as food with highly nutritional and economical value.

“…Experiments were performed with a ratio of 2g of algal biomass per 1L culture medium in Erlenmeyer flasks (1L). Treatments consisted of sterilized seawater supplemented by modified medium (Von Stosch media, this medium with iron salts, Manganese, EDTA, and three vitamins, not including phosphate and nitrate), according to Ribeiro et al (2017). Ammonium (NH 4 Cl) and phosphate (Na 2 HPO 4 .12H 2 O) were added to the Von Stosch modified medium in order to obtain a phosphorous/ nitrogen (P/N) ratio of 1:10.…”

“…The biomass was decreased on the second day of treatment at 8/80μmol/L, which maybe because of the high concentrations of ammonium. Ribeiro et al (2017) stated that high concentrations of ammonium (50-80μmol/L) could be toxic for some seaweed.…”

“…However, it is also crucial to choose the appropriate seaweed species that can be applied as biofilter in order to reduce nutrient pollution in water, improve water quality, fish growth, and maximize the economic value of the seaweed itself. In addition, the use of seaweed as a biofilter and bioremediator has been extensively investigated, such as Ulva, Palmaria palmata, Gracilaria, Kappaphycus, and Hypnea aspera (Trianti and Adharini, 2020;Andayani et al, 2016;Anibal et al, 2013;Carneiro et al, 2011;Castellar et al, 2015;Elizondo-González et al, 2018;Hayashi et al, 2008;Kang et al, 2011;Laramore et al, 2018;Neori et al, 2003;Ribeiro et al, 2017;Tremblay-Gratton et al, 2018).…”

Highlight ResearchWastewater in hybrid grouper culture should be maintain before resirculate and dispose to aquatic environment to avoid eutrophication.Seaweed that is used for biofilter must be observed for its suitability, performance and effectivity.Ulva sp. has the best effectiveness to reduce nutrient in wastewater of hybrid grouper aquaculture by absorbing then stored into thallus.Ulva sp. is proven has the best SGR and adaptability in wastewater of hybrid grouper culture.AbstractWastewater generated from hybrid grouper culture needs to be managed to improve water quality before being recirculated, or discharged in the aquatic environment. Seaweed biofilter has been proposed in wastewater treatment technology for marine fish farming. This study aimed at comparing which of these species i.e. Ulva sp., Sargassum sp., Gelidium sp., and Dictyota sp. work best to absorb nutrient wastewater hybrid grouper culture. This research utilized these seaweed as treatments and controls with three replications using Completely Randomized Design. A statistical analysis was conducted to investigate the significant differences in the nutrient absorptions among various seaweed species by using ANOVA and least significant difference. Non-parametric tests namely Kruskal-Walis, Mann-Whitney, and t-test were used with confidence interval of 95%. The results revealed that Ulva sp. has the best ability to reduce the Nitrogen 80%, while Dictyota able to reduce Phosphor 88% by Dictyota sp. generated from wastewater of hybrid grouper culture. While the highest absorbtion of Total Kjeldahl Nitrogen (104%) and phosphate (182%) that stored in thallus were performed by Ulva sp. Ulva sp. had the best performance and highest growth rate (1.9% d-1) as biofilter in hybrid grouper cultivation than other species.
