    Effects of Aloe vera extract on growth and some hematological parameters of shirbot, Tor grypus (Heckel, 1843) (2020)
    Details
    Publication Date: 2021-05-19
    Description: A feeding trial was conducted for sixty days to determine the effect of dietary Aloe vera on parameters related to growth rate, health status and hematological parameters of shirbot (Tor grypus). Two hundred and forty fish weighing 50-60 g were randomly subjected to four different treatments, including a control, T1 (0.1% of A. vera), T2 (0.2%) and T3 (0.5%) in triplicate. Hematological parameters and some growth parameters, including the body weight, total length, condition factor, feed conversion ratio, feed efficiency, specific growth rate and protein efficiency ratio were measured. Administration of fish to different concentrations of A. vera extract led to significant (p〈0.05) increase in total erythrocyte count, packed cell volume, and hemoglobin when compared with the control group. Mean corpuscular hemoglobin concentration were increased only in T2 and T3 in comparison with the control. When animals received 5% of A. vera daily, they showed a significant increase (29%) in white blood cells (p〈0.05). Growth parameters were improved with the addition of different concentrations of A. vera to fish food. According to the results obtained, it might be concluded that feeding this species with A. vera extract could likely enhance growth rate and also hematological parameters.

    Haemato-immunological responses to diazinon chronic toxicity in Barbus sharpeyi (2018)
    Details
    Publication Date: 2021-05-19
    Description: The present research aimed to determine acute toxicity and evaluate the effect of sub-lethal concentrations of diazinon on some haematological and immunological parameters of Barbus sharpeyi by the Organization for Economic Cooperation and Development methods. Juvenile B. sharpeyi were exposed to 0, 5%, 10% and 25% 96h LC50 concentrations of diazinon for 21 days. Blood samples were taken after 7, 14 and 21 days of exposure to diazinon. Haematological and biochemical parameters including: RBC, Hb, PCV and WBC, as well as serum enzymes were evaluated. Immunological indices and resistance against bacterial infection, were determined. Results showed that 96h LC50 of diazinon in B. sharpeyi was estimated at 3.987 mg/L. Diazinon toxicity at a level of 1 and 0.4 mg/L decreased RBC, Hb, and Hematocrite, in almost all sampling periods compared. WBC and globular index decreased significantly in fish exposed to 1 mg/L diazinon on days 14 and 21(p〈0.05). Dose dependent increase in serum enzymes were seen in fish exposed to diazinon. Diazinon toxicity showed no effect on serum LDH level (p〉0.05). Dose dependent decrease in serum total protein and globulin were indicated in diazinon exposed fish. Serum lysozyme and bactericidal activity decreased in T3 and T4 at days 14 and 21. Mortality following challenge to A.hydrophila increased in fish exposed to 1 mg/l diazinon. It can be concluded that diazinon is toxic to B. sharpeyi. Therefore, the strict biosecurity should be taken into consideration when this pesticide is used in agricultural fields surrounding freshwater sources of fish cultivation

Therefore, the strict biosecurity should be taken into consideration when this pesticide is used in agricultural fields surrounding freshwater sources of fish cultivation.

    Description: For this purpose, 144 specimens were studied in five healthy groups. The first group was the control group put in dechlorinated tap water and four respectively in the next group were kept with salinity 4ppt, 8ppt, 12ppt, 16ppt in the same condition. In days (1, 3, 7, 14, 21, 28) samples were collected from skin of head, ventral and lateral lines. Sections with 5- 6µm thickness were made and stained with PAS and H&E methods. In histometrical survey, epiderm thickness, numbering of club cells and goblet cells in 200 µm of epiderm length in any area, was investigated comparatively. The results showed that in different salinity concentrations, skin of head, ventral and lateral lines were influenced and changes in epiderm thickness, reduce the number of club cells and increase the number of goblet cells were demonstrated. These changes in different concentrations for each parameter, for significantly increased (p〈0.05).
