    Description: This study is a part of the national and technology master plan entitled "Attain to technical knowledge of specific pathogen free shrimp production and cut off to dependence on foreign products". The goals of this work were to assess and analysis the risk factors of production of specific pathogen free Litopenaeus vannamei shrimp in its all stages (broodstocking, laravl production, shrimp farming, feeding and water quality), determining the pattern of outcomes monitoring, management and control of outcomes from April 2012 to September 2015 in Bandargah research station and Persian Gulf SPF Shrimp research station and their environment, belonging to Shrimp Research Center, located in Bushehr. Identification and screening of risk factors have been done based on Environment Aspect and Effect Analysis method, (EA)2, using a fine statement questionnaire and quantification of risks. The number of identified risk factors in Bandargah research station was 15 while it was 13 in Persian Gulf SPF Shrimp research station. The more number of risk factors in Bandargah station in respect to its number in Persian Gulf station is might due to lower level of biosecurity, physical structure and aging of Bandargah station and existence of two possible source of contamination, the Bushehr nuclear power plant pollutants and Bandargah fishing harbor, near to the station. On the basis of results, the maximum values of APN in Bandargah station was 42 while it was 30 in Persian Gulf station. These results revealed that the level of risk in Bandargah station is lower than that in Persian Gulf station. The most probable risks in both studied research stations are related to transmission of pathogens in shrimp feeding and water intake pollution.

    Description: White spot syndrome virus (WSSV) is the causative agent responsible for huge-shrimp viral epidemics in shrimp farms throughout the world.Our study was aimed to determine the effect of WSSV Gamma-vaccinated Litopenaeus vannamei in occurrence of apoptosis. One thousand and twenty PL15 were randomly distributed among 2 treatments and two control groups. Gama-Vaccinated shrimp and none-Gamma-vaccinated ones were our treated and untreated groups. Our result showed there is a significant difference (p〈.05) between vaccinatedexposed group (82.33±2.51) and none-vaccinated exposed group (26.00±10.00) was about 56%. It is concluded that apoptosis can be a helpful process as immune function in shrimp especially against WSSV.

    Description: Nowadays, white spot virus disease is serious threat for breeding and culture industry of shrimp. In this study was increasing resistance of shrimp against white spot virus by using modern methods such as shrimp vaccination with inactivated viruses and recombinant proteins. The aim of this study were determine the growth and survival rates vaccinated and non-vaccinated of Litopenaeus vannamei (5 to 15 and 12 to 26 day), that were challenged with white spot virus in 40 and 60 day rearing. This study consisted two separate groups were vaccinated and non-vaccinated with 11 treatments experimental and each of replicate was stocked 1000 pieces by post larva of 5 to15 and 12 to 26 day. After vaccination, two groups of post larvae exposed to the white spot virus at 40 and 60 day, one groups no exposure to the virus. Samplings were randomly of shrimp in 40, 60 and 80 days 10 pieces each of treatment experimental and measured mean of weight and length. Also, number of deaths was recorded at morning and evening daily and calculated survival rate at the end of study. The results showed growth rate of post larvae vaccinated (5 to15 day) which exposed to white spot virus at 40 and 60 was significantly lower than non-vaccinated of post larval, while the growth rate of post larval exposed to virus in 60 day was significantly increased. On the other hand, growth rate of post larval vaccination (12 to 26 day) exposed to virus in 60 day compared with post larval vaccination (5 to 15 and 12 to 26) exposed to virus in 40 and 60 days was significantly increased. Hence, growth rate was significantly increased in post larval vaccinated (5 to 15 and 12 to 26) which non-exposed to virus. Although the survival rate was post larval vaccinated (12 to 26 days) exposed to virus Post larvae in 60 day higher than post larval were exposed to virus in 40 and 60, but no significant differences were observed. However, relative mortality of post larval vaccination in 12 to 26 day compared with post larval vaccination in 5 to 15 days exposed to virus were significantly lower. Considering growth and survival index was improved of post larval vaccination can be concluded that the optimum age for vaccination against white spot virus of L.vannamei was 12 to 26 day.

    Description: With the advent of the science of fisheries and aquaculture in the country, and the importance of reproduction and breeding of various species of aquatic animals (freshwater and salty water), attention has been paid to pathogenic factors in the process of aquaculture, one of these factors is pathogenic microorganisms and Nonpathogenic (bacterial, fungal, and viral) that can increase the environmental risk for aquatic organisms and, in some cases, human beings, and, with accurate knowledge of the disease, steps can be taken to prevent and treat withdrawal, as well as research and More studying on various pathogens in either natural or experimental conditions. Although many studies have been carried out over the years about aquatic microorganisms and aquatic environments, there is no complete information on genetic studies of microorganisms in the country, and if such research is feasible and not required, if Gathering information about these creatures and identifying their genetic reserves can provide the basis for research in various fields. What microorganisms are identified and maintained under standard conditions is a question that has remained unresolved so far and this study has tried to introduce a complete list of microorganisms, including bacteriafunges and viruses that have been isolated so far from aquatic and aqueous humor. And the aquatic microorganisms that have been identified in the microorganism bank are also included, and all the documentation shows that there is a huge potential for the identification and maintenance of these microorganisms. In this study, isolated and identified bacteria from northern waters, internal waters, and south of Iran were 73.39 40 genera and species, respectively. Viruses identified in northern waters, inland waters, and south of Iran were 4 species in aquatic and northern waters of Iran, 6 species in Iranian aquatic and inland waters and 7 species in aquatic and southern waters of Iran. Identification fungi have been reported in the waters of northern, inland and southern waters, respectively, 20,25 of the 12 genera and species. In the bank of the National Center for Genetic and Biotechnological Resources of Iran, there are some species that overlap with bacteria isolated from Iran's water resources. There are 20 species of bacteria, and this is not seen for fungi and viruses.
