“…The ISP results showed that after 30 days of cultivation, Sargassum sp. grew rapidly in a monoculture medium and integrated with prawn as 5.70 ± 0.82 and 0.74 ± 3.16 (% per day), respectively (Mai et al, 2010). Meanwhile, our SGR results on S. spinuligerum were much higher than other published studies on various Sargassum species in Florida, USA: S. cymosum (0.094 ± 0.011 % per day), S. filipendula (0.107 ± 0.003 % per day), S. fluitans (0.109 ± 0.003 % per day), S. natans (0.073 ± 0.005 % per day), S. polyceratium (0.078 ± 0.015 % per day), and S. pteropleuron (0.112 ± 0.008 % per day) (Hanisak and Samuel, 1987).…”

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 highest growth rates of the macroalgae (3.07 ± 1.44% day -1 ) were recorded with 24:00 h photoperiod and biomass ratio 1:8. The highest rate of N incorporation (0.31 ± 0.12 mg N L -1 ) of the macroalgae occurred under the same conditions. Shrimp growth was similar to data reported in traditional recirculation systems. The integration of G. vermiculophylla without water exchange system was able to maintain the TAN and N-NO 2 under levels conditions for the growth of L. vannamei.

“…The first is to use microbial processes that are enhanced through biological filters, reactors or digesters with examples from temperate IRAS and MWW treatment systems (Summerfelt 2006, Sharrer et al 2007, Roy et al 2010). The second is to use phototrophs (algae, cyanobacteria) to enhance assimilation, as has been demonstrated in commercial landbased fish farms and in laboratory studies with shrimps (Bartoli et al 2005, Henry-Silva & Camargo 2006, Mai et al 2010. Finally, the third is to combine these processes into a functional bioremediation mesocosm, comprised of multi-stage systems (Craggs et al 2004a) that may include a constructed mangrove wetland as an end point (Lin et al 2003).…”

Land-based aquaculture is an integral part of global aquaculture production for fishes (28.8 million t), molluscs (13.1 million t) and crustaceans (5.0 million t; FAO 2010, Hall et al. 2011. The majority of landbased systems which support the intensive culture of fresh, brackish and marine water organisms do so through the addition of high-protein feeds to sustain the rapid growth of intensively farmed animals ABSTRACT: Settlement ponds are used to remove particulate and dissolved nutrients in Australian land-based aquaculture wastewater. At best, marine and brackish water settlement ponds reduce total suspended solids by 60%, but their efficiency is inconsistent. Functional improvements to nutrient removal systems are essential to provide uniform and predictable treatment of flow-through aquaculture wastewater. Furthermore, environmental regulation of discharge from intensive systems in Australia is increasing, providing the impetus to upgrade rudimentary singlestep settlement pond systems. We characterise technologies used for land-based aquaculture wastewater treatment prior to discharge from shrimp systems in Australia. We identify opportunities to integrate technologies developed for the treatment of municipal wastewaters and intensive recirculating aquaculture systems, and use these to develop a model system for intensive shrimp farm wastewater. The first stage is the reduction of solids through the use of deep anaerobic ponds, which are tailored to dilute saline wastewater. Non-settled colloidal and supracolloidal solids can subsequently be removed through trapping in a sand bed filter and biological transformation to dissolved inorganic nitrogen or N 2 . The resulting dissolved nutrients can be treated in a 3-stage algal treatment system by assimilation into harvestable biomass, and finally constructed wetlands polish wastewater through further trapping of particulates, and transformation of dissolved nitrogen. Given that upgrading wastewater treatment facilities is costly, we highlight options that have the potential to offset nutrient treatment costs, such as the use of algal biomass for food or energy products, and the recycling of nitrogen and phosphorus via pyrolysis creating products such as biochar and biofuel.
