“…Los cultivos integrados que incluyen camarón y macroalga son escasos, algunos se encuentran en etapa experimental (Marinho-Soriano et al, 2009;Mai et al, 2010;Tsutsui et al, 2010;Khoi & Fotedar, 2011) y otros a escala piloto (Paredes-Escalona, 1999;Xu et al, 2008;Cruz-Suárez et al, 2010).…”

Efecto del fotoperiodo y la razón camarón:macroalga en la remoción de nitrógeno amoniacal total por Gracilaria vermiculophylla, en cultivo con Litopenaeus vannamei, sin recambio de agua ), N-NO 2 (0.145 ± 0.29 mg L -1 ) y N-NO 3 (3.13 ± 0.73 mg L -1 ) were registered in the biomass rate of 1:8. 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.

“…One of the major drawbacks of this trend lies in the waste derived from fish feed and its metabolic end products. These include uneaten food, feces and excreta, and dissolved inorganic nutrients, which are transported in water in various concentrations and can cause eutrophication of the water resources that receive them (23). Therefore, to combat this problem, a novel technique, i.e., a recirculatory aquaculture system (RAS), has been proposed, which is based on conservation of the limited water and abatement of water pollution caused by the expanding aquaculture industries.…”

Intensive aquaculture releases large quantities of nutrients into aquatic bodies, which can lead to eutrophication. The objective of this study was the development of a biological recirculatory wastewater treatment system with a diazotrophic cyanobacterium, Aulosira fertilissima, and simultaneous production of valuable product in the form of poly-␤-hydroxybutyrate (PHB). To investigate this possible synergy, batch scale tests were conducted under a recirculatory aquaculture system in fiber-reinforced plastic tanks enhanced by several manageable parameters (e.g., sedimentation, inoculum size, depth, turbulence, and light intensity), an adequate combination of which showed better productivity. The dissolved-oxygen level increased in the range of 3.2 to 6.9 mg liter ؊1 during the culture period. Nutrients such as ammonia, nitrite, and phosphate decreased to as low as zero within 15 days of incubation, indicating the system's bioremediation capability while yielding valuable cyanobacterial biomass for PHB production. Maximum PHB accumulation in A. fertilissima was found in sedimented fish pond discharge at 20-cm culture depth with stirring and an initial inoculum size of 80 mg dry cell weight (dcw) liter ؊1 . Under optimized conditions, the PHB yield was boosted to 92, 89, and 80 g m ؊2 , respectively for the summer, rainy, and winter seasons. Extrapolation of the result showed that a hectare of A. fertilissima cultivation in fish pond discharge would give an annual harvest of ϳ17 tons dry biomass, consisting of 14 tons of PHB with material properties comparable to those of the bacterial polymer, with simultaneous treatment of 32,640 m 3 water discharge.Over the last 2 decades, aquaculture has gone through major changes, growing from small-scale homestead level activities to large-scale commercial farming, which is driving the industry toward more intensive practices. One of the major drawbacks of this trend lies in the waste derived from fish feed and its metabolic end products. These include uneaten food, feces and excreta, and dissolved inorganic nutrients, which are transported in water in various concentrations and can cause eutrophication of the water resources that receive them (23). Therefore, to combat this problem, a novel technique, i.e., a recirculatory aquaculture system (RAS), has been proposed, which is based on conservation of the limited water and abatement of water pollution caused by the expanding aquaculture industries. The most prominent characteristic of this system is the presence of a biofilter, which treats water contaminated by dissolved organics and ammonia rather than discharging these contaminants directly into bodies of water.Cyanobacteria (blue-green algae) are O 2 -evolving photosynthesizing prokaryotes that can be successfully cultivated in wastewater due to their ability to use inorganic nitrogen and phosphorus for their multiplication. For example, Spirulina platensis (5, 10), Spirulina maxima (25), Romeria sp. (3), Synechococcus sp. strain PCC 7942 (16), Schizothrix calcicola, Pho...

“…Other integrated studies with Gracilaria gracilis also demonstrated a high capacity for removing these nutrients: around 93% and 62% of ammonium and phosphorous, respectively Martínez-Aragón et al, 2002). More recently, Marinho-Soriano et al (2009) showed that Gracilaria caudata was capable of reducing the concentrations of ammonium, nitrate and orthophosphate to 59.5, 49.6 and 12.3%, respectively, in only 4 h. Nutrient uptake rates achieved by seaweeds are generally based on the reduction of the concentration of a given nutrient in the culture medium. In these studies, kinetic parameters (V max and K s ) are quite useful for identifying the physiological abilities of a seaweed (Phillips & Hurd, 2004), supplying valuable data to help in the selection of species that can be used as biofi lters in eutrophized environments.…”
