Opis:
Indonesia is an archipelago with a coastline of about 81,000 km and has enormous cultivation potential. The area that's the potential for aquaculture is estimated at 15.59 million hectares, consisting of 2.23 million hectares of freshwater cultivation land, 1.22 million hectares of cultivated land in brackish waters, and 12.14 million hectares of marine areas. Nowadays, only 10.1% freshwater, 40% of brackish water, and 0.01% of the marine area potentially suitable for cultivation are being used. However, land use for shrimp farming until 2017 has only reached 20% of the total potential. It is still very open to developing land for the extensification of shrimp farming. Shrimp is one of the non-oil and gas export commodities that play a crucial role. Besides the high price, shrimp also has a large market in various countries. Although the industry suffered disease outbreaks and environmental problems, Vannamei shrimp farming has recently seen a rapid expansion in Indonesia due to superior varieties and disease resistant shrimp. Vannamei shrimp is a new variety that’s some advantages, including more resistance or resistance to disease and low environmental quality, high stocking density, shorter rearing time, which is around 90-100 days per cycle. This study provides some necessary background for Vannamei shrimp farming in Indonesia. It focuses on the operating characteristics of shrimp farming in brief. Emphasis is placed on the impact of shrimp farming on the environment. Promising strategies for reducing nutrient release from shrimp farming are analyzed. Effective management measures to resolve or mitigate the adverse environmental effect of shrimp farming development have now become necessary and urgent. The sustainability of shrimp farming depends on many factors including the completeness of policies and regulations, good ecology, superior breeding and various kinds of cultivation technology and government support, advances in technology digitization and cooperation between industries shrimp farming.

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.

Opis:
Rhyodacite sheets (the Sady Górne Rhyodacites) in the lowermost part of the Permo-Carboniferous Intra-Sudetic Basin molasse fill have been mapped as intrusives but, later on, based on ambiguous field and petrographic evidence, reinterpreted as lower Carboniferous lavas and tuffs; if so, they would mark the earliest episode of late-orogenic volcanism in the Intra-Sudetic Basin and in the whole Sudetes region in SW Poland. However, re-examination of field relationships and new observations are consistent with an intrusive emplacement of the rhyodacites as conformable to semiconformable, simple to composite sheets. SHRIMP zircon study indicates that the rhyodacites contain rare inherited zircons of ca. 560 Ma, and ca. 470 Ma (or slightly older), and a main population of zircons with an average concordia age of 306.1 š2.8 Ma. This latter age documents the emplacement of the rhyodacites during a mid/late late Carboniferous (Westphalian) stage of volcanism in the Intra-Sudetic Basin in the Central European Variscides. This post-orogenic volcanism was possibly initiated several million years later than previously assumed, and could have comprised a few pulses over a relatively prolonged time span of millions of years.

Opis:
The Gęsiniec composite intrusion in the northern part of the Strzelin Massif (Fore-Sudetic Block, SW Poland) was formed in the course of three late Variscan magmatic episodes: tonalitic I, granodioritic, and tonalitic II/granitic. The age of the Gęsiniec tonalite, 295 š3 Ma, is the same as that of another tonalite body in the southern part of the Strzelin Massif, the Kalinka tonalite. The younger biotite-muscovite (Bt-Ms) granite, in a dyke cutting the Gęsiniec tonalite, has an indistinguishable isotopic age of 295 š5 Ma; it contains, however, inherited zircons with ages between ca. 1.5 Ga to 374 Ma, similar to zircon ages from surrounding gneisses. This suggests that the magmatic protolith of gneisses and the magma of the Bt-Ms granite could have come from similar sources, or that the magma of the Bt-Ms granite was contaminated by the gneisses. Both the tonalite and Bt-Ma granite represent a late stage of the granitoid magmatism in the eastern part of the Variscan orogen.

Opis:
Acid sulfate soils in coastal wetland areas are particularly vulnerable to land-use changes. We identifid the potential impacts of land-use changes in the Can Gio coastal wetland area in Vietnam due to the reclamation of acid sulfate soils from shrimp farms. Our study applied the support of vector machine algorithm in ENVI software to observe land-use changes from 1995 to 2015, using Landsat Thematic Mapper and Operational Land Imager data. We classifid the land use of the study area into four major classes including vegetation, bare land, dedicated land and aquaculture land. Our study successfully met the overall classifiation accuracy requirement above 95% and kappa statistics above 0.95. Between 1995 and 2006, about 2,938.05 ha of bare land and 1,464.66 ha of vegetation (mangrove forest) were converted to aquaculture land. In contrast, between 2006 and 2015, 2,423.88 ha of aquaculture land converted back to bare land, mainly related to the abandonment of shrimp ponds due to crop failure and disease. The disturbance of acid sulfate soils through initial soil reclamation and subsequent fallowing is considered a key reason for hastening and extending soil acidifiation in the study area. We collected 144 topsoil samples from 17 fallowed ponds in two batches, and 142 of these were acidic: 128 samples were extremely and strongly acidic (pH < 5.5), 14 samples were moderately and slightly acid (pH between 5.5 and 6.5), and only two samples were neutral (pH over 6.5).

Opis:
The killer shrimp Dikerogammarus villosus was recorded for the first time in Lithuanian waters in 2015. The species was detected in three sites in the Curonian Lagoon (on two buoys in the lagoon strait and the harbour, and one littoral sampling site) and in the mouth of the Šventoji River. The species presence in the buoy fouling suggests the involvement of shipping in species introduction. Most likely D. villosus has arrived to the Curonian Lagoon with commercial ships, while the invasion into the mouth of the Šventoji River may be associated with leisure shipping as the port situated therein is not currently functioning. Further northward expansion of the killer shrimp in the Baltic Sea basin seems very probable. As the species is highly aggressive, alterations of local macroinvertebrate assemblages can also be predicted.

Opis:
Epibionts of ornamental freshwater shrimps bred in Taiwan. One of the major problems in breeding Neocaridina davidi in Taiwanese aquaculture ponds are epibionts found on the body of ornamental shrimp. These organisms affect shrimp wellbeing by causing distress which leads directly to shrimp weakness, loss of colour and even casualties. They can also be observed in imported shrimps which put in danger individuals bred in Europe, mostly characterised by high level of inbreeding and sensitivity to pathogens. Microscopic analyses indicated presence of 6 freshwater shrimp epibionts. Some of them showing parasitic lifestyle (Cladogonium ogishimae, Saprolegnia sp., Scutariella japonica), others (phyla Ciliophora and Rotifera) may indicate level of organic matter in water. To allow an effective treatment and control of the spread of parasites, all of their preferred locations on shrimp body observer in this study should be checked and become a vital part of diagnostic methods. Researches on ornamental freshwater shrimps’ epibionts are important to achieve success in shrimp breeding as well as to effectively monitor epibiont populations globally, especially that in some regions they may become potentially invasive organisms to the native crustaceans.
Epibionty krewetek akwariowych hodowanych na Tajwanie. Epibionty są jednym z głównych problemów w hodowli krewetek Neocaridina davidi w stawach hodowlanych na Tajwanie. Ich obecność wpływa negatywnie na dobrostan krewetek poprzez wywoływanie stresu, osłabienia, upadków oraz utraty ubarwienia. Są również stwierdzane na krewetkach pochodzących z importu, co jest szczególnie niebezpieczne dla osobników hodowanych w Europie charakteryzujących się wysokim poziomem chowu wsobnego oraz niską odpornością na patogeny. Analiza mikroskopowa wykazała obecność 6 gatunków symbiontów krewetek słodkowodnych. Niektóre z nich prowadzą pasożytniczy tryb życia (Cladogonium ogishimae, Saprolegnia sp., Scutariella sp.,), inne (typ Ciliophoraoraz typ Rotifera) mogą być wykorzystane jako wskaźniki ilości materii organicznej w wodzie. Wykazane w obserwacjach miejsca ciała krewetek preferowane przez pasożyty powinny stanowić nieodłączną część metod ich diagnostyki pozwalającej na efektywne leczenie. Badania na epibiontach krewetek akwariowych są szczególnie istotne dla sukcesywnej hodowli tych skorupiaków jak również dla prowadzenia efektywnego monitoringu populacji epibiontów, które w niektórych regionach świata mogą stać się gatunkami potencjalnie inwazyjnymi dla naturalnie występujących skorupiaków.

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.

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 paper is an attempt at a systematic review and a tentative synthesis of the philosophically most relevant theories of voice that are to be found within the psychoanalytic tradition. Beginning with some reflections borrowed from Thomas Ogden, the author proceeds to examine two lines of thinking about voice: the ‘paternal’ line which discusses voice mostly in relation to the superego and the orientation of the self and the ‘maternal’ line which discusses voice in relation to the processes of subjective constitution. Having analyzed selected insights of such authors as Freud, Reik, Isakower and Lacan within the paternal line and Lacan, Anzieu, Rosolato, Vasse, and Abraham&Török within the maternal one, the author attempts to show the common features of many of these diverse takes, focusing especially on the processes of internalization of external voices and on the strange status of voice as both most intimate and alien to us. The closing discussion of Mladen Dolar’s theory opens the way to a synthetic view of voice as the paradoxical kernel of human subjectivity.

The pink shrimp, Farfantepenaeus duorarum, is one of the most important shrimp species commercially harvested along the Gulf and Atlantic coasts of the US. In this study we developed a mitochondrial marker suitable for population studies of the species. A 611–617 bp hypervariable portion of the AT-rich region of the mt genome was amplified and sequenced. The 617 bp long consensus sequence contained 15 polymorphic insertion/deletion sites and 165 polymorphic substitution sites. Kimura 2-parameter distances ranged from 0.00 to 0.06 with a mean of 0.02. Among the 104 sequences, 100 haplotypes were counted if all mutations were included. If transitions were omitted, 34 haplotypes were observed. The results indicate that the hypervariable portion of the AT-rich region may be an effective marker for revealing the genetic structure of the pink shrimp off the southeast US.

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.
