Shrimp white spot disease (WSD), which is caused by white spot syndrome virus (WSSV), is one of the world's most serious shrimp diseases. Our objective in this study was to use an immunomagnetic reduction (IMR) assay to develop a highly sensitive, automatic WSSV detection platform targeted against ICP11 (the most highly expressed WSSV protein). After characterizing the magnetic reagents (Fe3O4 ...
White spot syndrome virus (WSSV), the causative virus of disease, is found in most shrimp farming areas in Iran, and it cause large economic losses to the shrimp farming industry. Shrimp aquaculture is an important industry in Iran and plays an important role in aquaculture production. The shrimp production in 2012 was more than 12000 metric tonnes and it is estimated it will reach 20000 tonnes...
Abstract Shrimp black gill is an emerging disease caused by a parasitic ciliate, Hyalophysa lynni , that attacks tissue in white shrimp Litopenaeus setiferus and brown Farfantepenaeus aztecus induces immune response produces melanized gills. This causes necrosis damage tissue, which limits metabolic capability can lead to high predation mortality among infected individuals. was first observed t...
Gastrointestinal ontogenetic studies constitute one of the basic and important investigations related to the nutrition of aquatic animals. In this investigation, specimens of the western white shrimp (Litopenaeus vannamei) at different developmental stages (from nauplius 1 to postlarvae 120) were assayed for the activities of digestive enzymes. According to the results, at all developmental sta...
Silver ion and hydrogen peroxide act synergistically as a strong disinfectant. The purpose of this study was to assess the effect of combined hydrogen peroxide 50% and silver ion 0.05% at four life stages of Indian white shrimp (Fenneropenaeus indicus) and to evaluate the feasibility of using this substance in shrimp culture. The Trimmed Spearman-karber software was applied for determining EC...
It has been found that appropriate probiotic applications increased growth performance and disease resistance in shrimp. Bacillus subtilis has been suggested as a potent probiotic in improving growth performance and enhancing immune response in white shrimp, Litopenaeus vannamei. The aim of this work was to evaluate the possible effect of B. subtilis administration on the meat fatty acid profil...

Certain parasites can cause severe diseases in shrimp. Among these, protozoa are very important. The objective of our study was to describe the signs, prevalence, and intensity of hemocytosis, a new disease in shrimp, Fenneropenaeus indicus. The experimental design included three groups, one treatment as infected shrimp or group B and 2 controls with non-infected but exposure to White Spot Synd...

postcolonial feminism, also dubbed as third world feminism, is an innovative approach, demonstrating the way women of colonized countries suffer from both native patriarchies and imperial ideology. also due to this double-colonization, postcolonial feminists contend that third world women are subjected to both colonial domination of empire and male domination of patriarchy. while western femini...
