“…To ensure the research findings, the added weights as gained from releasing juveniles for 3-month culturing were calculated in percentages of beginning weight and found as 69.55%, 65.29%, 46.30%, and 42.33% for densities of 105, 175, 245, and 315 juveniles in 3-cu.m concrete gutters, respectively. The percentages of added weight after culturing Whiteleg shrimps for 3-month period were obviously indicated that the more the densities of Whiteleg shrimp aquaculture resulted the very less the product which were similar almost as the studies of Wu & Yang (2011), Cahu et al (2012, Casillas-Hernandez et al (2007), Mariscal-Lagarda et al (2012), Xu et al (2012), Carvalho et al (2013), and Hai & Yakupitiyage (2005).…”

“…There have been various methods on how to treat shrimp-farm wastewater before releasing to the seawater sources, such as dilution, lagoon, oxidation pond technology, mangrove forest filtration, and constructed wetland technology (Tilley et al, 2002;Sklarz et al, 2009;Green & Ward, 2011;Chunkao et al, 2012;Mariscal-Lagada et al, 2012;Chunkao et al, 2014;Phewnil et al, 2014) but they were in doubted issue on efficiency and disease contamination. Because of such constraints, the advanced techniques were employed to treat wastewater from shrimp farms such as electrochemical technology (Mook et al, 2012), low-salinity shrimp farming (Prapaiwong et al, 2012), outdoor tank shrimp wastewater recirculation system (Lavania-Baloo et al, 2014), limited discharge and biosecure management tool , zero-water exchange culture tanks (Xu et al, 2012), high-intensively zero-exchange system (Burford et al, 2004), integrated culture with low salinity groundwater (Mariscal-Lagarda et al, 2012), semi-intensively managed shrimp pond waters (Green&Ward, 2011), EU recirculating aquaculture systems (Martins et al, 2010), culture ponds utilizing two different feeding strategies (Carrillo-Hernandez et al, 2007), and others. These approaches are exactly expensive and delicate to operate both during and after constructing, particularly to control the food residues as the main point sources of wastewater from shrimp ponds.…”

The research was aimed to recirculate the treated wastewater from Whiteleg shrimp farms in following each other without interruption by using concrete gutters containing ACM (Assembled Constructed Materials) check dams as the filters. Among the 2-inch diameter of chipped-assembled-constructed materials, the ACM-Brick filter was the most effective rather than roof-tile, blocked cement, and rock, respectively. Three ACM-Brick check dams with 5-m space between them were indicated as 47.3% treatment efficiency together with flow rates of 600 to 900 L/hr, and up to more 65% and 85% for fourth and fifth ACM-Brick check dams while the first and second dams found 13.0% to 28.4% efficiencies. Seemingly, irrespective of employing brick, roof-tile, blocked cement, or rock for constructing the ACM check dam was installed in concrete gutters with the size of 1-m width, 0.5-m depth, and more or less 20-m length that could be served needs in recirculation aquaculture of Whiteleg shrimps to gain satisfied benefits. Culturing Whiteleg shrimps in 3-sq.m. and 3-cu.m.concrete gutters containing only one of 0.5-sq.m. and 1-depth ACM-Brick filters by RCB design for 4 treatments (culturing shrimp densities) and 3 replications found the density of 105 juveniles/3m 2 (6,606 kg/ha) with the most harvested-added weight 2,710 kg/ha (69.55 % of beginning weight), and decreasing after increasing the density of 6,720, 8,371, and 11,382 kg/ha in corresponding to harvested-added weight 65.29%, 46.36%, and 42.33%, respectively. The findings also informed that flow rate of 720 L/hr indicated somewhat high effective influences on decreasing of water temperature, salinity, pH, DO, EC, alkalinity, TDS, BOD, NH 4 -N, NO 2 -N, and NO 3 -N which were conditioned for recirculation aquaculture of Whiteleg shrimps.

“…Higher PER results mean that a lower content of protein is present in fish feces and, consequently, the TAN concentrations of water will be moved downwards. Therefore, the bioflocs technology for aquaculture helps to make fish and shrimp farming a more environmentally sustainable activity (Xu, Pan, Zhao, & Huang, 2012). ; FCR: food conversion ratio = dietary allowance (g)/fish body increase (g); PER: protein efficiency ratio = fish weigh gain (g)/apparent protein intake (g).…”

ABSTRACT. The present study aimed to assess the possible beneficial effects of the integration between bioflocs and periphyton to the Nile tilapia's water quality and growth performance. There were four treatments with five replicates each: (1) Control: green waters, (2) Periphyton: substrate-based system, (3) BFT: bioflocs technology for aquaculture, and (4) Biophyton: integration between bioflocs and periphyton. Fish (1.63 ± 0.07 g) were reared for 10 weeks in twenty 250 L outdoor tanks. Two polyethylene boards were vertically set out in the Periphyton and Biophyton tanks as underwater substrates. The C: N ratios of water in the BFT and Biophyton tanks were adjusted to 15:1 with dry molasses applications. The concentrations of total ammonia nitrogen were higher in the Control and Periphyton tanks than in the BFT and Biophyton ones. On the other hand, the concentrations of reactive phosphorus were higher in the BFT and Biophyton tanks than in the Control and Periphyton ones. The fish final body weight, specific growth rate and fish yield have not differed between the tanks. The integration between bioflocs and periphyton has not brought clear benefits to tilapia culture on water quality and growth performance.Keywords: aquaculture, Oreochromis niloticus, water quality.Integração entre bioflocos e perifíton em tanques de cultivo da tilápia do Nilo RESUMO. O presente trabalho teve por objetivo determinar os possíveis efeitos benéficos da integração entre bioflocos e perifíton na qualidade de água e no desempenho zootécnico da tilápia do Nilo. Trabalhou-se com quatro tratamentos com cinco repetições cada: (1) Controle: águas verdes, (2) Perifíton: sistema de cultivo baseado em substrato, (3) BFT: tecnologia bioflocos para aquicultura e (4) Biofíton: bioflocos + perifíton. Os peixes (1,63 ± 0,07 g) foram mantidos por dez semanas, em 20 tanques externos de 250 L. Duas pranchas de polietileno foram posicionadas verticalmente, nos tanques Perifíton e Biofíton, como substratos submersos. A relação C: N da água dos tanques BFT e Biofíton foi ajustada para 15:1 pela aplicação de melaço à água. As concentrações de nitrogênio amoniacal total foram maiores nos tanques Controle e Perifíton do que nos tanques BFT e Biofíton. Por outro lado, as concentrações de fósforo reativo foram maiores nos tanques BFT e Biofíton que nos tanques Controle e Perifíton. O peso corporal final, a taxa de crescimento específico e a produtividade de peixe não diferiram entre os tanques. A integração entre bioflocos e perifíton não apresentou claros benefícios para a criação da tilápia, em relação à qualidade da água e ao desempenho produtivo.Palavras-chave: aquicultura, Oreochromis niloticus, qualidade de água.

“…The system is based on a live microbial which beneficially affects the host animal by improving its microbial balance [10]. The role of microorganisms is increasing culture feasibility by reducing FCR and depreciating feed cost [8,9,11]. Thus, high stocking density can be applied in this system that is biologically safe [12].…”

Abstract. Glass eels of Anguilla bicolor is an expensive and still abundant commodity in Laguna Segara Anakan, Central Java, Indonesia. However, the growth of glass eels to elver is still a problem because of high mortality in nursery I and II. The objective of the study was to evaluate the result of stocking density on the performance of glass eels in the biofloc system during nursery I. Glass eels were stocked at densities of 54.95, 109.89 and 164.84 fish/m 3 , respectively, with three replicate ponds for each density. Eels were fed a formulated pasta-diet containing 40% crude protein and , 4% crude lipid, 5% crude fiber, 11.5% ash and 12% moisture, respectively. The water quality were maintained at levels of for fish culture througout the experiements: water temperature was 27.1 o C (ranged from 26.3 to 28.2 o C), pH (7.6, ranged from 6.8 to 7.8) and DO (7.2 mg.L -1 , ranged 6.9 to 7.5 mg.L -1 ). The results showed that the stocking density did not significantly affect the final weight, weight gain, AGR, SGR, FCR and survival, however this had a significant effect on the yield. The biofloc system was suitable for raising glass eels.
