Abstract (sommario):
White spot syndrome virus is recognized as the most prominent pathogen of penaeid shrimp and has been affecting this shrimp farming industry around the world. The virus may reduce the shrimp’s immune response and alter enzymatic and biochemical composition of tissues. Similar to other environmental stressed or other pathogeninfected shrimp, in late stages of WSSV infection, shrimp will fail to clot the haemolymph, so any minor injury will lead to increased haemolyph loss. A series of experiments to determine the effect of non-clotting haemolymph on WSSV infection were carried out in controlled facilities in Indonesia. The preliminary test showed that normal clotting time was 13.3 seconds while WSSV-injected shrimp mostly failed to clot their haemolymph 16 hours post infection (hpi). Some other clinical signs such as abnormal swimming, red discoloration, white spots and mortality were consistent with those observed by previous studies. Three shrimp species: banana shrimp (P. merguiensis) 9 g , white leg shrimp (P. vannamei) 7 g and the tiger shrimp (P. monodon) 16.5 g were water-borne-challenged with non-clotting, WSSV-infected haemolymph (NCH) from tiger shrimp donor in duplicate tanks each with 12 shrimp. The control were tiger shrimps fed with WSSV-infected tissue at the rate of 40% of bodyweight (BW) and other tiger shrimps were used as negative controls fed with commercial feed only.The study revealed that NCH dosages of 1.46%; 2.03%; and 2.06% (v/v) for eachspecies were sufficient to infect and kill all shrimps in less than two days comparedto eight days for the shrimps fed on infected tissue. The WSSV in non-clottedhaemolymph eventuallyattaches into the living tissues of healthy shrimp. This modeof infection is likely more difficult to control by the ordinary fine mesh screeningmethod.

Abstract (sommario):
Avicennia alba is a mangrove plant that often ued by coastal society as a traditional medecine, it is potential to be dveloped as the sources of pharmaceutical. The aim of the research is to examine the effect of Avicennia alba leaves extract various concentrations to Vibrio harveyi infection on vaname shrimp. The addition of the extract is thought to be used as an antibacterial so that it can give effect to the attack of V. harveyi in vaname shrimp. Vaname shrimps (total of 120 shrimps) with a weight of 10±2g/ind were injected intramuscularly with V. harveyi bacteria in 107 CFU/ml density. After the occurrences of clinical symptoms, the shrimps were immersed into A. alba leaves extract with concentration 0 ppm, 150 ppm, 250 ppm, and 350 ppm for 21 days. The results showed that the addition leaves extract can increase shrimp’s survival rate as much as 46.67% and increase the shrimp’s ability to prevent (RPS) V. harveyi infection untill of 70±15%. The mean time of death (MTD) was 106±18.33 hours, it caused there ar active compounds contained such as saponin, tannin, and steroid be suspected antibacterial so that they can protect shrimp from the effect of Vibrio infection damage. Giving a concentration of 250 ppm Avicennia alba leaves extract can treat vaname shrimp which was attacked by V. harveyi better than other treatments.

Abstract (sommario):
<p>The use of antibiotics for controlling of luminous vibriosis caused by <em>Vibrio harveyi</em> is restricted now, because it induces antibiotic-resistant bacteria and leave residue in shrimp’s body. An alternative solution that can be done to treat the disease is by using applications of probiotic, prebiotic, and synbiotic. The aim of this research was to examine the effect of probiotic, prebiotic, and synbiotic on the survival rate and growth of Pacific white shrimp against <em>V. harveyi</em> infection. Feed as a treatment was supplemented with probiotic 1%, prebiotic 2%, and probiotic 1%+prebiotic 2% (synbiotic). Shrimps feed without supplementation of probiotic and prebiotic was used as a control treatment. The shrimps were maintainedin the aquarium (60×30×35 cm<sup>3</sup>) with a density of 40 shrimps/40 L and an average weight of 0.4±0.1 g. After 30 days of feeding treatment, the shrimp was challenged by immersion method with <em>V. harveyi</em> solution containing 10<sup>6</sup> CFU/mL. The results showed that before challenge, synbiotic feed treated shrimp has a growth rate (5.89%), feed conversionrate (1.21), and a high survival rate (80%). After challenge, survival rate (83.33%) of shrimp fed diet supplemented with synbiotic was higher than prebiotic (51.67%) and positive control (31.67%).</p> <p>Keywords: probiotic, prebiotic, synbiotic, <em>Vibrio harveyi</em>,Pacific white shrimp</p>

Abstract (sommario):
This study investigated the occurrence of microplastics (MPs) in the gastrointestinal tracts (GT) and tissues of four common shrimps (including two wild-caught shrimps and two farmed shrimps) collected from a high-diversity lagoon in central Vietnam. The numbers of MP items in greasy-back shrimp (Metapenaeus ensis), green tiger shrimp (Penaeus semisulcatus), white-leg shrimp (Litopenaeus vannamei), and giant tiger shrimp (Penaeus monodon), determined per weight and individual, were 0.7 ± 0.3, 0.6 ± 0.2, 1.1 ± 0.4, and 0.5 ± 0.3 (items/g-ww), and 2.5 ± 0.5, 2.3 ± 0.7, 8.6 ± 3.5, 7.7 ± 3.5 (items/individual), respectively. The concentration of microplastics in the GT samples was significantly higher than that in the tissue samples (p < 0.05). The number of microplastics in the farmed shrimp (white-leg shrimp and black tiger shrimp) was statistically significantly higher than the number of microplastics in the wild-caught shrimp (greasy-back and green tiger shrimps) (p <0.05). Fibers and fragments were the dominant shapes of the MPs, followed by pellets, and these accounted for 42–69%, 22–57%, and 0–27% of the total microplastics, respectively. The chemical compositions determined using FTIR confirmed six polymers, in which rayon was the most abundant polymer, accounting for 61.9% of the MPs found, followed by polyamide (10.5%), PET (6.7%), polyethylene (5.7%), polyacrylic (5.8%), and polystyrene (3.8%). As the first investigation on the MPs in shrimps from Cau Hai Lagoon, central Vietnam, this study provides useful information on the occurrences and characteristics of the microplastics in the gastrointestinal tracts and tissues of four shrimp species that live in different living conditions.

Abstract (sommario):
In recent years, the Beninese shrimp sector has faced a ban on export to the European Union due to lack of compliance with food safety standards. The present study aimed at obtaining insight into the factors that determine shrimp quality and safety in Benin. A survey was conducted to investigate the relationships between stakeholders, the conditions under which shrimps are handled at fishing areas and processed at shrimp plants, and the stakeholders' perceptions of quality. A total of 325 fishermen, 128 intermediate traders, 12 collectors, and 3 shrimp processing plant managers were interviewed face to face. The results showed that various specific relations existed between the stakeholders. For example, loyalty was ensured by family relationships, or incentives were provided to ensure a supply of shrimps between stakeholders. Shrimp handling practices during the steps prior to shrimp processing at the plants were not in agreement with the requirements of the European regulations. For example, shrimps were kept at ambient temperature (28 ± 1°C) by 94.1% of fishermen and 60.9% of intermediate traders. Shrimps were also stored in inappropriate holding containers and washed with nonpotable water. Fishermen, intermediate traders, and collectors considered shrimp size and texture their priority quality attributes, whereas plant managers considered shrimp appearance (freshness) and texture their priority quality attributes. This survey demonstrated that the steps prior to shrimp processing at the plants are the critical steps for shrimp quality and safety because of temperature abuse and inappropriate hygienic conditions. There is a need to communicate and provide incentives for the stakeholders in the first part of the chain to give priority to shrimp freshness. Moreover, training in Good Fishing Practices and safe food handling practices and evaluation of compliance with the practices through monitoring will contribute to better shrimp quality and safety management.

Abstract (sommario):
Selenoprotein is a feed additive that can overcome oxidative stress in intensive Pacific white shrimp (Litopenaeus vannamei) culture. This study evaluated the effects of selenoprotein supplementation at various doses on Pacific white shrimp’s digestibility, growth, and health performance. The experimental design used was a completely randomized design consisting of four feed treatments, namely, control and treatments with selenoprotein supplementation of 2.5, 5, and 7.5 g kg feed-1 with four replications. Shrimps (1.5 g) were reared for 70 days and challenged for 14 days by the bacteria Vibrio parahaemolyticus (107 CFU mL-1). Shrimps used in the digestibility performance evaluation (6.1 g) were reared until sufficient quantities of feces were collected for analysis. Shrimp supplemented with selenoprotein exhibited superior digestibility, growth, and health performance compared to the control ( P < 0.05 ). The use of selenoprotein at a dose of 7.5 g kg of feed-1 (2.72 mg Se kg of feed-1) was considered the most effective for increasing productivity and preventing disease attacks in intensive shrimp culture.

Abstract (sommario):
One of the most popular seafood in the world is shrimp, including cooked shrimp. Boiled shrimp is a value added product with high protein content, specific taste, ready to eat, and have an interested colour for consumers. Boiled shrimp must be protected from quality deterioration during storage. The research was carried out to study the effect of carrageenan coating to inhibit the quality deterioration of boiled shrimp based on organoleptic evaluation during refrigeration storage (4-6oC). Peeled undevined (PUD) vannamei (Litopenaeus vannamei) with size 60-70 was used as object. The boiled shrimps treated with two treatmens, which were coated and uncoated boiled shrimps. Application of coating carrageenan on boiled shrimp indicate that coating application could extend its shelf life, proved by higher organoeptic value than uncoated product, based on organoleptic evaluation for frozen boiling shrimp (SNI 01-2346-2006).

Abstract (sommario):
Shrimp is one of the seafood which is nutrient-rich needed by the body. However, due to the frequent case of the infected Tenggek-shrimp appeared, it makes people beware to consume it. The classification of Tenggek-shrimp by using image processing of the computer be able to classify the types of shrimp whether poisonous or not. The data mining techniques can be used to classify shrimp based on RGB colors (red, green, blue) and texture (energy, contrast, correlation, homogeneity). The class of Tenggek-shrimp is divided into two, The fresh Tenggek-shrimps that are caught naturally (Class A) and the poisoned Tenggek-shrimps that are caught by using the poison (Class B). The method used in this study is K-Nearest Neighbor (K-NN). This classification system is expected to help the people in selecting good and safe Tenggek-shrimp for consumption. Based on the evaluation results using the holdout method, obtained an average accuracy of 63% with an accuracy of identification of toxic tenggek shrimp of 71.66%, and the accuracy of identification of natural fresh shrimp is about 60%.

Abstract (sommario):
The objective of this research was to evaluate the nonspecific immune response and resistance of Litopenaeus vannamei fed with nucleotide, β–glucan, and protagen diets. Shrimp juveniles with an average weight of 5.39±0.56 g were reared in glass aquaria at a density of 15 shrimps/aquarium. Shrimps were fed three times a day for four weeks at a feeding rate of 3%/bw/day. Treatment diets consisted of A: basal diet (without immunostimulant), B: β–glucan, C: protagen, and D: nucleotide, each with three replicates. At the end of feeding period, the shrimps were intramuscularly injected with Vibrio harveyi 0.1 x 106 cfu.shrimp-1. Total haemocyte count (THC) of shrimp fed with nucleotide-diet was significantly different compared to that of control shrimp (p=0.01), but not different compared to shrimp fed with protagen-diet. PO activity also increased significantly in shrimp fed with nucleotide-diet (p=0.02). β–glucan diet could also increase THC and PO activity, but compared to the control, the increase was not significantly different. Overall, PO activity of shrimp fed with nucleotide, β–glucan, and protagen diets was high (>0.35). Oral administration of nucleotide, β–glucan, and protagen for four consecutive weeks significantly increased resistance of shrimp to disease (<0.01) where the highest resistance rate was observed on shrimp fed with nucleotide-diet. Growth of shrimp fed with nucleotide-diet was significantly different compared to that of control shrimp (p<0.01), as well as to β–glucan, and protagen-treated shrimp. As a conclusion, supplementation of nucleotide into shrimp pellet enhanced nonspecific immune response and growth performance better than β-glucan, and protagen.

Abstract (sommario):
Purified brush border membrane vesicles (BBMV) were isolated to characterize primary cellular transport mechanisms for white shrimp. The ultimate goal is to determine the effective components of a shrimp’s diet, thereby enhancing growth, as well as nutrient content. Juvenile shrimp are dependent on plant material as a food source. Potassium is a key component of plants, thus it may play a role in nutrient transport. In addition, divalent metals have been shown to act as co-transporters in several other organisms, thus they may serve as a transport mechanism for shrimp. Fresh, live, white or brown shrimp were obtained, and from them 15-30 hepatopancreases were dissected to prepare the BBMV. Methods for preparing BBMV were based on the Mg2+ precipitation technique developed by Kessler et al., (1978) and Biber et al. (1981) for mammalian eipithelia and applied to crustaceans. The results suggest that there is a sodium/potassium-dependent glucose transport system that resembles the SGLT1 system of vertebrates, except the shrimp transporter can accept both sodium and potassium as cofactors, while the vertebrate system is restricted to sodium stimulation. Potassium showed strong stimulation of L-histidine uptake by shrimp BBMV, suggesting that a crustacean isoform of the insect potassium-dependent carrier protein (KAAT1) might be present in shrimp, and contribute to amino acid uptake. Amino acids also appear to form bis-complexes with divalent metals, that are transported by an analog of the dipeptide transporter (PEPT1). The metals appear to be accommodated, with varying affinities. PEPT1 has been described as a very non-specific carrier process because it transports such a wide range of di- and tripeptide combinations.

Testo completo
Abstract (sommario):
Integrated rice–shrimp ponds (IRSPs) are common in areas of southeast Asia where saltwater intrudes into rice fields in the dry season, leading to rice planting in the wet season, and shrimp farming in the dry season or throughout the year. The rotation of rice with shrimp in this system is thought to increase environmental sustainability and contribute to food security. Nevertheless, the productivity of IRSPs is generally low and unreliable, and technical solutions do not address the impacts of climate change. Consequently, farmers experience reduced livelihood and lifestyle opportunities. The understanding of the biogeochemistry in shrimp ponds has focused on water column processes. However, shrimp live at the sediment–water interface where chemical and biological processes in and on the sediment, and the effects on water quality, can impact shrimp health, and overall pond productivity. This PhD research examines the sediment biogeochemical processes particularly relevant to shrimp health in IRSPs, i.e. nutrients and oxygen. Options for modifying conditions to improve IRSPs productivity are also discussed. The study examined ISRPs in two districts of Ca Mau Province, Vietnam. In the nutrient budget study, 12 farms in Cai Nuoc District were examined. It became clear that this district was marginal for sustainable rice production; hence in order to examine biogeochemical processes in more detail, two ISRPs in Thoi Binh District, where rice production was more sustainable, were investigated. A combination of measurements of parameters in the water and sediment were combined with nutrient and oxygen flux measurements in situ (pond side) to understand the dynamic nature of these systems. The first step in understanding biogeochemical processes was to estimate nutrient budgets in IRSPs. The study showed that the main nutrient input (92% of the N input, 57% P and 95% C) came from intake water, while water discharge accounted for the highest output (75% of the N output, 41% P and 57% C). Hence, most of the nutrients were not assimilated in the ponds. The main reason for this poor assimilation was low shrimp densities and survival (6.3 ± 2.2%); thus the nutrients did not convert to shrimp biomass. This, combined with the low rice harvest (mostly no rice crop due to high salinity affecting rice production), supports the conclusion that IRSPs seemed to be inefficient systems. Furthermore, fertilizer addition only accounted for 8% N, 43% P and 5% C of the total input, and thus fertilizer addition was likely to be an unnecessary expense. The study also found that IRSPs had periods of low dissolved oxygen (DO) concentration which may have a critical negative effect on shrimp survival. To understand the causes of low DO, oxygen fluxes were examined at two IRSPs during a two-year period. The key finding was that a high percentage of oxygen demand at a whole pond scale was from the sediment; hence sediment oxygen demand (SOD) drove low DO concentrations in the water column. Moreover, oxygen demand was considerably higher than oxygen production within the IRSPs, indicating high bacterial activity relative to algal production. SOD rates were significantly positively correlated (p < 0.05) with chlorophyll a concentrations in the water column. These findings suggest that algal production in the water column, rather than benthic algal production, or other organic loadings, provided an organic carbon source driving SOD. Sediment nutrient pathways were also examined at the same two IRSPs to understand drivers of poor water quality. The study showed that the IRSPs had low denitrification efficiency. Denitrification rates were significantly positively correlated with chlorophyll a concentrations in the sediment, suggesting carbon availability was a key driver. Nitrate, ammonium and phosphate concentrations in the water column were high despite low sediment nutrient fluxes. Given the low sediment nutrient fluxes, and low N removal by denitrification, high nutrient loads in the ponds were likely derived from incoming water. Despite the low mean values for denitrification, the fact that values at some sites within the ponds were high suggests that there was scope to enhance denitrification, via C addition, and hence to improve water quality. In summary, this study examines key nutrient biogeochemical fluxes in IRSPs and shows, for the first time, that sediment was a main driver of low oxygen conditions in these ponds. High nutrient loads, which also ultimately helped drive low oxygen conditions, were the result of poor quality incoming water and inefficient N removal via denitrification. Nutrients were mostly in-fluxing into the sediment; hence sediment nutrient fluxes were relatively low and were minor contributors to water column nutrients. These key findings indicate that rather than contributing to eutrophication in adjacent waterways, IRSPs were net nutrient removal mechanisms.

Abstract (sommario):
Field measurement and modelling of the material cycle are carried out for the cultivation pond of penaeid shrimp Penaeus japonicus. The main purpose of the present study is to investigate the sustainability of coastal shrimp aquaculture, which is increasingly being questioned due to many problems like disease, excessive nutrient enrichment, and low levels of dissolved oxygen tension. Despite the great economic importance of shrimps and their suitability to aquaculture, little is known about the material cycle through the cultivation pond. Additionally, the collapse of shrimp aquaculture in most tropical countries may be attributed to the lack of ecological, biological, and environmental understanding. Hence field measurement of water quality is conducted in the shrimp cultivation pond, which locates in the Kyushu district of Japan. Various environmental factors such as water temperature, salinity, and the concentrations of dissolved oxygen, nutrients, and chlorophyll a are monitored for the water in the pond and that drawn from the outer sea during November and December of 2006. In addition to field measurement, one dimensional numerical model is developed for the shrimp cultivation pond to understand the material cycle through the pond in a quantitative manner. The numerical model consists of physical, lower trophic-level ecosystem, and shrimp growth submodels. The numerical values of physical and physiological parameters are calibrated to achieve the best agreement between observed and simulated results. By integrating results from field measurement and numerical simulation, it is revealed that the quality of water in the cultivation pond is quite different from that drawn from the outer sea. In particular the concentration of chlorophyll a is much higher in the cultivation pond due to large primary production. The results of the numerical simulation show that the high productivity is attributed partly to the activities of shrimps. The information from field measurement and the simulated results of the developed numerical model are useful to optimize the food quantity and quality, the population density of shrimps, and the design of watermills or the other equipments to improve the water quality for sustainable use of coastal shrimp cultivation pond.

Abstract (sommario):
The FAO has projected a doubling in world demand for seafood during the 21 ed from aquaculture of marine fish and shrimps fed primarily on fishmeal-based aquafeeds. However, current practices of high intensity monoculture of shrimp in coastal ponds and fish in offshore pens have been strongly criticized as being ecologically and socially unsustainable. This view derives from un- checked eutrophication of coastal marine ecosystems from fish farm effluents, and the destruction of coastal estuarine ecosystems by shrimp farm constructions, plus aquaculture’s reliance on wild-caught small fish - which are excellent food for humans, but instead are rendered into fishmeal and fish oil for formulating aquafeeds. Fishmeal-sparing and waste- reduction aquafeeds can only delay the time when fed aquaculture product are priced out of affordability for most consumers. Additionally, replacement of fishmeal protein and fish oil by terrestrial plant sources such as soybean meal and oil directly raises food costs for human communities in developing nations. New formulations incorporating sustainably-produced marine algal proteins and oils are growing in acceptance as viable and practical alternatives. This BARD collaborative research project investigated a sustainable water-sparing spray/drip culture method for producing high-protein marine macrophyte meals for incorporation into marine shrimp and fish diets. The spray culture work was conducted at laboratory-scale in the USA (UCSD-SIO) using selected Gracilariaand Ulvastrains isolated and supplied by UCONN, and outdoors at pilot-scale in Israel (IOLR-NCM) using local strains of Ulvasp., and nitrogen/phosphorus-enriched fish farm effluent to fertilize the spray cultures and produce seaweed biomass and meals containing up to 27% raw protein (dry weight content). Auburn University (USA) in consultation with TAMUS (USA) used the IOLR meals to formulate diets and conduct marine shrimp feeding trials, which resulted in mixed outcomes, indicating further work was needed to chemically identify and remove anti-nutritional elements present in the IOLR-produced seaweed meals.
