    Evaluation of the immunity factors (THC, TPP, PO, SOD, POD) of shrimp fed with the yeast Saccharomyces cerevisiae compared to shrimp fed without yeast (2018)

    Description: Effects of S. cerevisiae on immune parameters of the L. vannamei after 14 days of S .cerevisiae feeding were evaluated in this study. For this purpose a total of 300 pieces of shrimp with an average weight of 30 to 35 grams were selected from a pool shrimp Abadan CHOEBDEH. After making sure the health, absence of necrosis on the surface of the body, cuts antenna, shrimp were transferred to the center of BANDAR IMAM Research Station. Adaptation was carried out for 3-5 days. After the adaptation, shrimps were screened for virus (WSSV, TSV, MBV, HPV, YHV, BP, IHHNV and IMNV) and vibrio bacteria.After screening shrimps divided to two groups with three replication (including 50 pieces of shrimp in triplicate). The experimental diet has the commercial shrimp composition ,but 2 g of S. cerevisiae substituted 2 g of fish meal. Shrimp of first group (T1) for 14 days with food containing nutritional yeast and shrimp in second group (T2) were fed with normal diet without yeast. After 14 days Immune Factors and survival rates in both groups were evaluated. The results showed that the relative survival rate between the two groups showed no significant difference. But Immune Factors (THC, TPP, PO, POD and SOD) in the treatment fed yeast (T1) compared to control treatment (T2) showed a significant increase. In conclusion these results suggest that the increased survival rate and resistance of shrimp after S. cerevisiae consumption occurs through immune modifications, such as increases in THC, TPP, SOD, SOP and PO activity.

    The Study of Establishment of Rainbow trout Culture and Hachery’s Farms on Zayanderood’s River region in Caharmahal and Bakhtiyari Province (2018)

    Description: The aim of this study was to find the best location for establishment of rainbow trout culture and hatcheries farms on Zayanderood’s river region in Charmahal and Bakhtiyari province. This survey carried out over ten station along Zayanderood’s river. The result of physical and chemical analysis showd that the annual average of air temperature varied from 9.5oc o 10oc wehre the pH annual average value were between 7.5 and 8.8. the dissolve oxygen concentration in stations except in rainbow trout farm effluent were above 10 mg/l. the other chemical , pollutant as well as pesticides levels were under the limiting concentration for rainbow trout culture and Hatcheries activity . The plankton survey showed that the Bacillurophyta were the dominant group of phytoplankton where protozoa constituted the most abundant group of zooplankton the Benthic organisms sensitive to pollutant in particular Epirus were dominant group in all stations . In regard to fishes presence in river , five species of Ciprinidae , one species from Balitoridae and one species from salmonidae families were identified . The capacity for development of rainbow trout culture for tow phase period in Zayanderood’s river region with respect to self purification potential (self purification potential were determined from the oxidation of the effluent of the only active trout farm of the river region), minimum of 10 L/s water requirement for production of trout in concrete canal and pond system and 1L/S water need for production in semi circular closed system were estimated to be 5202 metric tons.

    Description: White spot disease (WSD) is one of the shrimp deadliest viral diseases that causes heavy losses on all shrimp of Penaeid family. Most invertebrates are lacking adaptive immune system and its defense is the innate immune system that is as cellular and humoral, but a like immune system against white spot virus in shrimp was been detected. In this research, control and prevention of white spot disease in shrimp using algae Gracilaria corticata, investigated. About 300 vannamei shrimp were divided to 4 groups and fed by normal pellet and algae extract in 14 days. At the end of the fourteenth day half of the shrimp were challenged with acute white spot virus. After the fourteenth day in the days 0, 3, 9, 18 and 25 sampling were done from the hemolymph of survived shrimps and survival and immune factors were evaluated. Based on results, in the challenge test, shrimps that fed with algae extract has a significant survival rate than shrimp fed with commercial diet. Increased the Immune Factors from day one to day 25 observed during the test. Greatest amount of Immune Factors THC, TPP, SOD, POD and PO in T1 group were observed in day 25 of tests. This situation was also true for group2 (T2), but its rate significantly was less than group 1(T1).
