    Gill chloride cells and prolactin hormone are of high importance in the adaptation of euryhaline fish. Guldenstati (Chalcalburnus chalcoides, 1772), an adromous fish, migrates from the Caspian Sea to rivers to have a more successful reproduction. The present study was aimed to evaluate the changes in the number and size of C. chalcoides gill chloride cells as well as to determine the relationship of its plasma prolactin with water salinity. Eighty-four individual C. chalcoides were collected from river (Lale Roud; 0.4 ppt), Lale Roud estuary (3.75 ppt), and Caspian Sea (9.71 ppt). The sampling was lasted for a-12 month period in 2014. The highest (1349±152) and lowest (881±37) number of gill chloride cells were observed in the animals collected from the Caspian Sea and in the river (Lale Roud), respectively. However, plasma prolactin demonstrated the highest level in C. chalcoides caught from the river (0.89±0.02 ng ml-1), but the lowest amount (0.70±0.03 ng ml-1) in the ones collected from the Caspian Sea. Overall, these results suggest that C. chalcoides migration across its habitats is an energy consuming ecological behavior, and the fish consumes high energy just after breeding and while returning to the Caspian Sea.

    Freshness is one of the main quality attributes for processing, marketing and consumption of fish. Fish is increasingly becoming the favored food of people in many countries as it is rich in proteins. However, the disadvantage associated with broader consumption of fish products is their comparatively short shelf-life. Therefore, effective methods for extending shelf-life and improving quality of fresh silver carp fillets are necessary. The goal of this study was to evaluate the biochemical and microbial changes of silver carp fillets in different packaging including aerobic, vacuum and modified atmosphere packaging (MAP) when stored at 4ºC for 15 days. Data obtained from these tests was averaged and subjected to the analysis of variance (ANOVA) using SPSS software. The fillets packaged at MAP had significantly (p

    The objective of this paper focused on the ffects of dietary nucleotides (NT) on histopathological alternations of striped catfish Pangasianodon hypophthalmus, after exposure to water-borne silver nanoparticles (AgNPs) and silver nitrate (AgNO3). Fish were fed with a diet containing nucleotide (0.75%) or control diet for 10 weeks and then divided into 3 experiments including control, 20 µg L-1 of AgNPs or AgNO3 for 10 days. At the end, histopathological changes in gill, liver and kidney were evaluated using haematoxylin-eosin technique. Water-borne AgNPs or AgNO3 caused some distinctive histopathological alterations in both feeding group. The most important damages were observed in epithelial cell hyperplasia, inflammation and necrotic epithelial cell in the gills, pigmentation, fiber cells and cytoplasmic vacuolization of hepatocytes in the liver and visualization of red blood cells and eosinophils, glomerular and tubular necrosis in the kidney. Based on organ index (Iorg), the highest damages were observed in the tissues of the fish fed on the control diet and exposed to 20 µg L-1 of AgNPs. No significant differences were observed in histopathological alterations between two feeding groups when compare the same organs with similar pollutant (kind and concentration). It could be concluded that dietary NT could not improve the fish ability against water-borne AgNPs or AgNO3.

    Emerging contaminant in drinking water has created concerns among public, water supplier and government. Pharmaceutical in water and food even in low concentration have shown potential risks to human. Acetaminophen and ibuprofen are among a set of the most prescribed drugs in the world. In this study raw water and treated drinking water from Latyan drinking water treatment facilities were analyzed to determine possible concentration of acetaminophen and ibuprofen in water. All the data were subjected to analysis of variance to consider significance of differences. Furthermore mean comparison between data was calculated using Duncan test. Presence of acetaminophen in the ground water resources was not reported. While in the Jajrood river and Latyan Dam Lake the concentration of acetaminophen were 2.16 ± 0.09 and 9.17 ± 0.18 ηg L-1 respectively. In the case of ibuprofen the only observed concentration was equal to 11.49 ± 0.33 in the Latyan Dam Lake. No concentration of acetaminophen and ibuprofen was detected in drinking water samples gathered after treatment process.Why pharmaceuticals were known as indicators for controlling the quality of raw water and the treatment efficiency in the drinking water treatment facilities, ground water and treated water of this area are safe with no detection of acetaminophen and ibuprofen.

    Zataria multiflora is well known to middle-east, Iran, Afghanistan and Pakistan where, it is cultivated only in warm areas. The objective of this article focused on this issue whether Zataria multiflora Boiss has effect on haematological and Growth parameters of Oncorhynchus mykiss. One hundred and twenty healthy finger ling fish, Oncorhynchus mykiss (mean weight 4.3 g) were commercially obtained and then transferred to the research field located in Tehran. Fish were fed on diets covering 0, 50, 100 and 150 mg kg-1 Z. multiflora (Z.M.) as four groups; in triplicates. All of them were hand-fed (3-4% of body weight) to satiation 6-8 times a day for 8 weeks (60 days). There was no significant difference (p> 0.05) among the fish fed the different levels of Z.M for the mean weight. The maximum value of SGR was observed in group 50 ppm of Z.M. (2.85 ± 0.01) with significant difference (p 0.05) compared with group 50 ppm of Z.M. The result of WG for group 50 ppm of Z.M. (453.86 ± 0.46) showed a significant difference (p 0.05). Against, the values for Hb and MCH were significantly lower than others (p

    The study evaluated the effects of Levamisole, Quil-A and Cinnamon on growth, hematological and immune parameters of marmalade cichlid. Fish (2.00 ± 0.02 g) were fed diets supplemented with 0.2% Levamisole, 0.5% Quil-A and 1% Cinnamon for 60 days and the control group was fed with basal diet. The highest weight gain and condition factor were observed in fish fed diet enriched with Levamisole followed by Quil-A. There was no significant difference between the three treatments in specific growth rate (SGR) (p>0.05). However, the SGR showed a significant difference in the control group (2.16 ± 0.02% day-1) compared to other treatments (p0.05). The lowest FCR was recorded in fish fed diet enriched with Levamisole (1.74 ± 0.95). The highest levels of RBCs, hemoglobin and hematocrit were observed in Levamisole treatment, but the highest number of WBCs was recorded in Cinnamon treatment (16766700 ± 450.92 mL-1). The maximum level of lysozyme was also observed in Cinnamon treatment (8.84 ± 0.38 µg mL-1). While no significant difference was recorded in the levels of the basophil, eosinophil, and monocyte, the highest levels of neutrophils (25.00 ± 1.0%) and lymphocytes (78.33 ± 0.57%) were observed in Cinnamon treatment. So, the use of Levamisole significantly improved growth performance and hematological parameters, but immunological parameters were improved with fish fed diet supplemented with Cinnamon.
