  In 2007, mass mortality occurred in juvenile shrimp L. vannamei in most farms of Bousherprovince in the south of Iran. The gross sign of moribund shrimp was red discoloration in bodysurface as well as in tail and appendage. The gut of shrimp was empty and by close observationmany necrotic area were seen in the tail and appendage. 200 samples collected and fixed inDavidson fixative for histopathology. The small part of pelopoda was preserved in ethyl alcohol95% for polymerase chain reaction. The histopathological finding that characterize in acute formof TSV were multifocal necrosis in the cuticular epithelium and often, the subcuticularconnective tissue and at time, the underlying striated muscles, multiple, spheroid inclusion bodywere scattered the affected area of cuticle tissue. This spherical inclusion body in H&E/Phstaining showed eosinophilic to basophilic color in hind gut and stomach. The samples alsoexamined by PCR KIT for TSV infection by IQ 2000TM WIT Multivir System and IQ 2000TMTSV Detection and Prevention Kit (Farming IntelliGene Technology Corporation, Taipei,Taiwan) with the respective RNA extracts. The PCR results showed positive reaction toinfection with TSV. Manuscript profile

  . The aim of this study was to identify and detection of microsporidian parasite from sub-adult brood stock culture of Litopenaeus vannamei by histology studies and histopathological lesions examination in various organs caused of parasite. The sub-adult brood stocks (27.81±0.92 gram) were randomly sampled more than 450 pieces from greenhouse ponds of three breeding center of Bushehr province, from January to March 2014. Based on the clinical symptoms, some of shrimps were white and milky cephalothoraxes and dorsal-ventral abdominal muscles. According to wet mount and histology observations, spore of Plistophora sp were separated from infectious shrimps. Histopathological lesions of hepatopancratic infectious shrimp were including nucleus hyperthrophy of epithelial cells, change shape of B-cells, necrosis of E-cells and dilation of tubules along with necrosis of muscle cells and decline of ovaries. The results showed that length and weight means of infectious shrimps comparing contamination free of shrimp were significantly deference (P <0.05).   Manuscript profile

  Inroduction and Objective: In the research undertaken in this thesis, in order to measure the concentration of heavy metals (lead, cadmium, nickel and vanadium) in the muscle tissue of shrimp, the two sites of Helleh and Shif that are centers of Vannamei shrimp in Bushehr province were sampledduring the three months of August, September and October 2012.Material and Methods: The collected samples were divided into males and females, and Polarograph was used to measure the amount of heavy metals in muscle texture.Results: The mean results of the concentration of cadmium in site of Helleh were 0.004 ppb in the muscles of both males and females; the concentration of lead in male was 0.0211ppb and in females 0.0202 ppb on a dry weight basis. Also, the mean result for cadmium in site of Shif was 0.0043 ppb in the muscle of males and 0.0037 ppb in females, and the concentration of lead in males was 0.0218 ppb and in females 0.0216 ppb on a dry weight basis. Finally, the accumulation of metals Pb>Cd at both sites of Helleh and Shif was obtained. The accumulation of lead and cadmium in both sites is positively correlated with the length of shrimp, and the extent of absorption of the two metals, lead and cadmium, had a moderate positive correlation However, the accumulation of nickel and vanadium in both sites was not detectable by PolarographConclusion: Comparing these results with international standards such as the World Health Organization shows that the concentration of lead, cadmium, nickel, and vanadium is less than the limit, and accumulation of metals and therefore probably intended for export as well as consumer health will make it difficult to raise.

  The aim of this study was to evaluate the heavy metals (nickel and lead) that has accumulated in Litopenaeus vannamei in vicinity of two types dispersants, Naft roob (Iranian dispersants) and Radiogreen OSD (foreign dispersant). For this study, a control group and 5 treated with different concentrations and combinations and each with three replications were considered. Shrimp samples exposed to crude oil and combination of crude oil and two dispersants for 48 hours. The accumulated heavy metals were then measured by atomic absorption spectrometry. Results showed that the highest average concentration of nickel in shrimp, was found to be in the combined treatment of Naft roob at 4.484 ppm,. The highest average concentration of Pb was found in L. vannamei, which was exposed to foreign oil dispersant, Radiogreen OSD, at 2.443 ppm. Finally, it was found that by increasing crude oil and dispersant concentration, higher levels of heavy metals were absorbed by the shrimp in vicinity of crude oil and crude oil combined with dispersants.  Nickel was also found to be accimulated at much higher concentrations compared to lead in shrimp exposed to crude oil and crude oil combined with dispersants.

  This investigation was conducted to survey the growth and survival rate, weight average, FCR, and harvestable white leg shrimp biomass during 107 days culture in mono and poly culture earth pond system with mullet fish. Nine 600 m2 earth ponds  were prepared and stocked with 20 shrimp post larvae in each pond (mean weight 0.007 ±0.001 g) for three treatments (each with three replication). After 40 days, the mullet fish fingerlings collected from the Oman Sea (with mean weight 35 g) released to earth ponds with a density of zero (T1 as control), 2 (T2), 4 (T2) per 100m2. During the culture period, water temperature, dissolved oxygen, pH and salinity were measured. One way ANOVA results showed that there were significant differences between growth rate, shrimp biomass, FCR and abiotic parameters (P<0.05), but not for survival rate (P>0.05). The highest shrimp biomass was harvested from T3 (with 212 kg and a mean weight of 18.4 g individual shrimp) and the lowest (with 187 kg with a mean weight of 16.23 g individual shrimp) was from T1. However, there were no statistically significant difference in survivorship between treatments, but the highest survival percentage was observed in T3 (95.96%) and the lowest in T2 (94.5%). Duncan's test in FCR average showed no significance difference between T1 (the lowest FCR, 1.2 ±0.1) and T2 (P>0.05), but there was a significant difference between these two treatments and T3 (the highest FCR, 1.27 ±0.2) (P<0.05). The conclusion expressed that polyculture of white leg shrimp and mullet fingerlings in earth pond not only performed more shrimp production compare to mono shrimp culture system.    Manuscript profile

  Background and Objectives: Nowadays, Shrimp culture has been prevailed in most of tropical countries; however, a variety of diseases have currently affected the business worldwide. Infectious bacterial agents are the most significant hygienic problems observed in the cultured shrimps . This study was aimed to isolate and identify microflora of farm ponds and western white shrimp gastrointestinal tract (Litopenaeus vannamei) in the Bushehr Province farm ponds and their survey as probiotic. Materials and Methods: The shrimp and pond water samples were collected from 10 farm ponds (located at Bushehr Province). After transferring the samples to laboratory, the shrimp samples were autopsied to access to their intestinal microflora. The isolated bacteria were identified based on biochemical tests, morphology and Biolog software. Antibacterial activities of the isolates against 6 common pathogenic bacteria in shrimps were then investigated using well diffusion and disk diffusion methods. Results: Overall, 12 bacterial genera were isolated from the farm ponds and shrimp gastrointestinal tract. The majority of bacterial species most abundantly isolated were Bacillus, Vibrio and Pseudomonas. Among the isolated bacteria, Bacillus, Micrococcus and Corynebacterium showed the most antibacterial activity against evaluated pathogenic bacteria. Conclusion: Almost all the isolated bacteria from shrimp gastrointestinal tract were found in farm ponds as well. The bacterium Bacillus sp., for instance, is able to inhibit the growth of pathogens through secreting antimicrobial products. Manuscript profile
