Treatment with seaweeds confirmed that nutrients from the aquaculture farm discharges could be converted in to seaweed biomass in a laboratory scale treatment experiment Enteromorpha flexuosa removed 87.2% of nitrite 87.2 % of nitrate, 82.5% of ammonia and 84.1% of phosphate and Gracilaria verrucosa removed 94.5% of nitrite 91.4% of nitrate, 99.3% of ammonia and 100% of phosphate from the discharge waters of aquaculture farm in a period of 20 days. Concentration of dissolved oxygen level…

Optimization of Macroalgal Density and Salinity for Nutrient Removal by Caulerpa lentillifera from Aquaculture Effluent
Determining the optimum levels of macroalgal density and salinity for removing aquaculture effluent has gained increasing research interest in recent years because of the growing concerns over
Phycoremediation in aquaculture; a win-win paradigm
ABSTRACT The ever-growing aquaculture sector has a great economic and environmental cost as it has been responsible for severe water pollution and ecosystems failure. The presence of high
Co-culture of Nile tilapia (Oreochromis niloticus) and red seaweed (Gracilaria tenuistipitata) under different feeding rates: effects on water quality, fish growth and feed efficiency
TLDR
The results proved that the co-culture of tilapia–red seaweed supplied at 80% feed ration, which could reduce feed cost by 28.9% compared with the control, still sustained normal growth while also maintaining better water quality.
A state-of-the-art review on dual purpose seaweeds utilization for wastewater treatment and crude bio-oil production
Abstract Due to the negative environmental impacts of fossil fuels and the increasing global energy demands, biofuels are receiving increasing attention as the best short-term substitute for
Analysis on Aquaculture
TLDR
Aquaculture, otherwise called aquafarming, is the cultivating of amphibian living beings, for example, fish, scavangers, molluscs and sea-going plants in freshwater and saltwater populaces under controlled conditions.
PERFORMANSI INSTALASI PENGOLAH AIR LIMBAH TAMBAK SUPERINTENSIF
TLDR
Evaluated the design and performance of a WTP in reconditioning waste water released from a super-intensive shrimp farm prior to release to water bodies to reduce organic matters contained in super- intensive shrimp farm effluent.

Halophytes for the treatment of saline aquaculture effluent
TLDR
The feasibility of using salt-tolerant plants (halophytes) as biofilters to remove nutrients from saline aquaculture wastewater was determined and Suaeda and Salicornia performed better than the desert saltbush, Atriplex, at the higher salinities.
Biotreatment of fish farm effluents using the cyanobacterium Phormidium bohneri
TLDR
The use of a non-toxic cyanobacterium, Phormidium bohneri, to remove dissolved inorganic nutrients from fish farm effluents is investigated and the potential use of P. bohNERi as an alternative for the tertiary treatment ofFish farm effluent is analyzed.
Physical models of integrated waste recycling- marine polyculture systems
TLDR
The final effluent from the system is virtually free of inorganic nitrogen and is incapable of supporting further growth of marine life or of contributing to eutrophication of the receiving waters.
A proposed model for “environmentally clean” land-based culture of fish, bivalves and seaweeds
TLDR
A model system is proposed, in which particulate and dissolved metabolites from the effluents of fish culture are removed by biofilters of bivalves and seaweeds, which yields fish yield and seaweed yields that contain 63% of the N budget.
Ulva lactuca Biofilters for Marine Fishpond Effluents. I. Ammonia Uptake Kinetics and Nitrogen Content
TLDR
The results indicate that 10m2 of Ulva biofilter can remove from the effluents of the authors' intensive grow-out ponds over 90 percent of the ammonia produced by 1 kg of daily feed ration or by approximately 75 kg of fish.
Outdoor pond cultivation of the subtropical marine red algaGracilaria tenuistipitata in brackish water in Sweden. Growth, nutrient uptake, co-cultivation with rainbow trout and epiphyte control
TLDR
It is concluded that G. tenuistipitata can be cultivated in outdoor ponds in southern Sweden during 5–6 months of the year using aerated or unaerated batch cultures and that wastewater from trout cultivation may be used as a nutrient source, resulting in purification with respect to N and P.

Marine Algal Flora From Selected Centres Along The Madras Coast
TLDR
A survey was made on the marine algae occurring at Pulicat, Kovalam, Muthukadu andMahabalipuram along the Madras coast and 16 species are recorded for the first time along theMadras coast.
