Opis:: The objective of this research was to produce safe water for shrimp by using zeolite as adsorbent to absorb unwanted substances (NH3 and H2S). In particular, this study also aimed to design the shrimp pond water treatment equipment, effect of flow rate on zeolite ability to absorb toxic gases (NH3 and H2S), and rate of absorption (K) and reaction (k). The adsorbent is zeolite which has adsorption properties, high surface area and pores suitable for water (3Å). Then, the concentration of ammonia, hydrogen sulfide was analyzed using Ammonia Test Kit and Hydrogen Sulphide of Hach Hydrogen Sulfide Test Kit. The materials used in this study were zeolite of Malang (East Java, Indonesia) and shrimp pond water. The best result of NH3 and H2S adsorption obtained at a flow rate of 3 L•min-1. The best adsorption constant value (K) achieved by a flow rate of 3 L•min-1. On the basis of the best value of R2, NH3 and H2S adsorption, it can be classified in the first-order kinetic model with R2 of 0.9763 and a k value of 0.0007 hours-1 with a flow rate of 6 L•min-1. From the data above, it can be calculated that the adsorbent needed in the adsorption of NH3 and H2S in a scale shrimp pond requires 18 kg of Malang zeolite with a column height of 3.62 m of adsorbent, a diameter of 2.07 m, and a column volume of 12.21 m3.

Tytuł:: Preparing Shrimp Shell-Derived Chitosan with Rice Husk-Derived Biochar for Efficient Safranin O Removal from Aqueous Solution

Tematy:: adsorption

Opis:: In this study, the shrimp shell-derived chitosan was coated onto rice husk-derived biochar to form chitosan/biochar bio-composite beads. The physicochemical properties of biochar (BC) and chitosan/biochar beads (CS@BC) were characterized by BET, SEM-EDX, FTIR, and pHpzc analyses, which were then tested for their capacity to remove Safranin O (SO) from water. In kinetics, the pseudo-second-order model was found to well represent experimental data, indicating the adsorption was mainly a chemical process. The intra-particle diffusion model was not the sole rate-limiting step, because the results did not pass through the origin. In isotherms, both the Langmuir and Freundlich models described well the equilibrium adsorption data. The CS@BC adsorbent showed adsorption capacity at 77.94 mg/g for SO, which is higher than BC adsorbent with 62.25 mg/g (experimental conditions: pH ~ 7.0, dosage = 0.2 g, contact time = 240 min, and temperature = 298 K). The findings revealed that the biochar-loaded chitosan can improve the adsorption capacity of SO. It is predicted that the enhancement in the functional groups (i.e., -NH2 and -OH groups) of CS@BC could contribute to the electrostatic interactions and the complexation between SO and CS@BC, thereby enhancing the Safranin O adsorption from water.

Opis:: Shrimp activity is associated with the impact of bacterial communities. Therefore, this research aimed to evaluate the influence of the bacterial microbiota on the organic matter content of the soil of the shrimp lagoon in La Segua-Ecuador. Starting from a descriptive approach, the field research method and documentary review were used. In total, 25 soil samples were collected in 5 quadrants of 100 m2. The bacterial DNA was extracted by using the Powersoil® kit and the identification of the strains was carried out with the 16SrDNA gene. The organic matter content was determined by Walkley-Black titration. The genus Bacillus was predominant in the bacterial strains; moreover, individuals of the genera Exiguobacterium, Acinetobacter, Prolinoborus, Arthrobacter Planococcus were identified with more than 99% homology for all cases. It was concluded that the organic matter content is suitable for shrimp farming.

Opis:: The investigation within the framework of this study was carried out on three marine species fished off in Moroccan coasts, namely: a fish, the sole (Solea Vulgaris), a cephalopod, the cuttlefish (Sepia Officinalis) and a crustacean, the pink shrimp (Parapenaeus Longirostris). The aims of this study were assessing the level of concentration in these three marine species, of three metallic trace elements: lead (Pb), cadmium (Cd) and mercury (Hg) and giving a reflection on the way in which Moroccan deep-sea fishing professionals can join a food safety management system to ensure the safety of their product and promote their competitiveness. Sampling was carried out at the port of Agadir city after landing of the deep-sea fishing boats which operate beyond 10 nautical miles, offshoring the seabed of Agadir for pink shrimp (Parapenaeus Longirostris), and in Dakhla city offshore for sole (Solea Vulgaris) and cuttlefish (Sepia Officinalis). Trace metal analysis was performed on individual muscles belonging to the three species. The results of the conducted investigations show that the Pb content varies between 0.01 ppm and 0.27 ppm in Solea Vulgaris; between 0.015 ppm and 0.16 ppm in Sepia Officinalis and between 0.022 ppm and 0.38 ppm for Parapenaeus Longirostris. For Cd, the concentrations vary between 0.0047 ppm and 0.050 ppm in Solea Vulgaris; between 0.0025 ppm and 0.254 ppm in Sepia Officinalis and between 0.0065 ppm and 0.11 ppm in Parapenaeus Longirostris. Concerning Hg, the contents vary between 0.0006 ppm and 0.075 ppm in Solea Vulgaris; between 0.0008 ppm and 0.05 ppm in Sepia Officinalis and between 0.0016 ppm and 0.09 ppm in Parapenaeus Longirostris. It appears from this study that the metal contents detected at the level of the three species of seafood investigated are below the regulatory thresholds. These results can be considered as the first basis for validating the control measure linked to the absence of metallic contamination of the three species in the sites studied.

Tytuł:: Comparison Environmental Conditions and Economic Efficiency Between Organic and Non-Organic Integrated Mangrove – Shrimp Farming Systems in Ca Mau Province, Vietnam

Opis:: Mangrove forest protection is an essential solution for mitigating the impacts of natural disasters in coastal zones and climate change. Integrated mangrove-shrimp farming (IMSF) system has been promoted as a sustainable livelihood that can provide income for farmers and protect mangrove forests. However, the productivity of shrimp is limited. Therefore, to enhance the revenue for farmers, improving the value of shrimp products is a good option. Organic shrimp farming practices following the EU aquaculture organic standards have been previously applied in some areas of the Mekong delta. This study was conducted to compare technical, financial characteristics and environmental parameters between the applied (i.e., organic farms) and non-applied (i.e., non-organic farms) standards of Naturland, aiming to support the development of ecological shrimp farming and contribute towards green development. The study was carried out in Nhung Mien mangrove forest, Ngoc Hien district, Ca Mau province, Vietnam. Fifty organic farms and 50 non-organic farms were directly interviewed using structured questionnaires. And then, three farms in each system were selected for monitoring water quality. Results showed that the average mangrove coverage was 54.1% in the organic IMSF system and significantly different from the non-organic IMSF system (p<0.05). Total shrimp yield, total income and total profits tended to increase in organic IMSF system and the selling shrimp price increased by 10% compared to the conventional price. The study showed that following organic farming methods could provide higher income for farmers and a better chance to mitigate natural disasters and climate change impacts.
