“…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).…”

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.

“…Páez-Osuna and TronMayen (1996) previously reported that L. vannamei from estuarine ecosystems and from cultured shrimps accumulates Pb in its body tissues. In contrast, in Zhanjiang Harbour bay, Wu and Yang (2011) did not find Pb in the shrimp muscle. Frías-Espericueta et al (2001) noted that sublethal and LC 50 concentrations of L vannamei were 134 mg/L total Pb at 96 h, corresponding to LC 50 2.71 mg/L dissolved Pb.…”

Determination of the accumulation and elimination of sublethal lead (Pb) in different shrimp tissues may be useful as an indicator of uptake and elimination characteristics of this metal. Aquaculture ponds are particularly influenced by Pb contamination, where aquatic animals may acquire the metal through adsorption to exoskeletons or gills from the surrounding water. Cationic Pb is accumulated preferentially in the nonedible fraction of shrimp, followed by exoskeleton, and to a minor extent in muscle. Lead contents in different tissues were lower than metal levels in exoskeleton. However, the presence of Pb in sediment due to purging may exert adverse consequences on shrimp as bottom feeders.

“…The muscle tissues of the fishes were separated and freeze-dried in order to obtain a constant weight and were finely grounded. For metal analysis, approximately 1.0 g of the grounded samples was digested in 5 mL of concentrated nitric acid at 135°C for 4 h; then, 1 mL of hydrogen peroxide (30 %) and 1 ml of concentrated perchloric acid were added, and the temperature maintained at 150°C until the liquid was clear (Wua and Yang 2011). Then, the resulted solution was filtered and after the filtration, the clear solution was diluted to 15 mL and the pH was adjusted to 5.0 using NaOH or HNO 3 for further analysis.…”

In this research, a new sample treatment technique termed solvent-assisted dispersive solid phase extraction (SADSPE) was developed. The new method was based on the dispersion of the sorbent into the sample to maximize the contact surface. In this approach, the dispersion of the sorbent at a very low milligram level was achieved by injecting a mixture solution of the sorbent and disperser solvent into the aqueous sample. Thereby, a cloudy solution formed. The cloudy solution resulted from the dispersion of the fine particles of the sorbent in the bulk aqueous sample. After extraction, the cloudy solution was centrifuged and the enriched analytes in the sediment phase dissolved in ethanol and determined by FAAS. Under the optimized conditions, the detection limit for silver ions was 0.8 μg L(-1). The relative standard deviations for six separate extraction experiments for determination of 5 and 200 μg L(-1) of silver ions was 3.4 and 3.1 %. The preconcentration factor was found to be 61.7. SADSPE was successfully applied for trace determination of silver ions in water and food samples.
