  • Effect of pituitary extract, ovaprim and combination of human chorionic gonadotropin and metoclopramide on reproductive performance of Caspian shemaya, Alburnus chalcoides (Guldenstadt, 1772)

    Nosrati, M.; Khara, H.; Vahabzadeh, H.; Mirhashemi Nasab, S.F. (2019)
    The present study was conducted to examine the effects of three different hormonal treatment types i.e., pituitary extract (Pt), ovaprim (Ov) and human chorionic gonadotropin (HCG) + Metoclopramide (Met) on reproductive performance of Caspian shemaya, Alburnus chalcoides (Guldenstadt, 1772). To this end, three experimental treatments and one control group were considered. The experimental groups were administrated with different doses of Pt, Ov, HCG + Met as follows: Pt [2 mg kg bw (body weight)^-1], Pt (3 mg kg bw^ -1), Pt (4 mg kg bw^ -1), Ov (10 μg kg bw^ -1), Ov (20 μg kg bw^ -1), Ov (30 μg kg bw^ -1), HCG + Met (1000 IU kg bw^ -1), HCG + Met (2000 IU kg bw^ -1), HCG + Met (3000 IU kg bw^-1) and also a control group without any hormonal treatment. The highest values of oocyte weight and egg diameter were observed in groups administrated with Ov (10 μg kg bw^-1) and HCG + Met (2000 IU kg bw^-1) respectively. The highest values of absolute fecundity and relative fecundity were recorded for fish administrated with Ov (20 μg kg bw^-1). The latency period and hour-degree for final maturation were lower in fish administrated with Ov (10 μg kg bw^-1) compared to other experimental groups (p<0.05). There were no significant differences between experimental groups in terms of other assayed parameters. The results of the present study demonstrated higher efficiency of ovaprim in improving the reproductive performance of Caspian shemaya
  • Fishery and population dynamics of Caspian kutum, Rutilus frisii kutum (Cyprinidae), in the Caspian Sea

    Afraei Bandpei, Mohammadali (Universiti Sains Malaysia, 2010)
    The Caspian Sea is the largest enclosed body of water in the world. The water is slightly brackish. The aim of project was to determine length at maturity (Lm_50%), evaluate of feeding items, investigation some of biological aspects included in sex ratio, growth and age structure, instantaneous mortality coefficient, maximum sustainable yield (MSY) and break-even point of Rutilus frisii kutum in southern part of the Caspian Sea. Specimens of Kutum were collected from the catches obtained from 131 sample sites along the Iranian coast of the Caspian Sea. The minimum and maximum fork length and weight was 21cm and 58cm with mean 38.4±6.4 cm; 104 and 2450 g with mean 775.2±382.5 g, respectively. The sex ratio of males to females was 0.65: 1 (males: females). The condition factor in Guilan was more than Mazandaran and Golestan provinces. The length at maturity (Lm_50%) of Kutum obtained was 39.1cm. The minimum and maximum absolute fecundity varied from 15,713 to 130,737 eggs with mean 69,961.7±3,836.4. The reproduction phase was extended from February to April, peak in March, with the highest average values 5.52 for males and the highest value was 17.00 for the females in April. Due to males‟ migration from sea to river occurred sooner than that of the females. The diet consisted of different prey items, bivalves representing the most important prey group (59%), and followed by Cerastoderma lamarki (57%). The instantaneous natural mortality rate was estimated M= 0.46 y^-1. Based on total instantaneous mortality coefficient (Z) from the seasonalized length-converted catch xxv curve, F (the instantaneous fishing mortality coefficient) as 0.82 y^-1 through the relationship: F=Z-M, and giving a current exploitation rate E (=F/Z) as 0.64 y^-1. The length-at-first capture and age-at-first capture was obtained L_c =36.8 cm and 3.92 years, respectively. The Maximum sustainable yield (MSY) based on cohort analysis for Kutum resulted MSY=20,004 tonnes with biomass B of 51,937 tonnes. The selection ogive procedure gave the following summary: E_max=0.76, E_0.1=0.65 and E_0.5=0.39. Yield per recruit analysis suggests that the stock of this species has a moderately exploitated at E=0.64. Kutum contributed about 76% of total sell bony fish in south of the Caspian Sea and total income of Kutum sell were estimated US$30,415,998. The income of the fishermen through selling of Rutilus frisii kutum from total bony fish income was 74% for Guilan, 85.8% for Mazandaran, and 26% for Golestan provinces. Therefore, R. f. kutum plays a significant role in fishermen‟s income in southern coasts of the Caspian Sea. The break-even point of Kutum obtained with mean 19,220±5,364.5 for Guilan, 18,843±4,989.2 for Mazandaran, and 10,677±1,358.2 for Golestan provinces, which coincided with the fishing effort, catch ratio, number of fishing cooperatives, and number of labour.

  • Evaluation of toxicity and biochemical effects of the Oxadiargyl in Common carp (Cyprinus carpio L.)

    Emadi, Hossein; Shariatzadeh, Somayeh; Jamili, Sh.; Mashinchian, Ali (2018)
    This study aimed to investigate the effects of sublethal concentrations of oxadiargyl herbicide on growth performance, serum biochemical parameters and liver histology of the common carp, Cyprinus carpio, during 30 days exposure period. Carp fingerlings were randomly divided into four duplicate groups. Experimental groups were exposed to the concentration of 0.1, 0.3 and 0.5 ppm of oxadiargyl, while the control group was kept in toxicant free. During the experiment, none of the control fish died. Weight gain and condition factor decreased, while food conversion ratio increased in fish exposed to 0.5 ppm of oxadiargyl. Exposure to oxadiargyl significantly increased serum ALT, AST and ALP, as well as glucose levels, while cholesterol, total protein and albumin were significantly decreased in the exposed fish groups depend on oxadiargyl concentrations and exposure time. Diffuse and focal necrosis mainly as perivascular necrosis fibrosis, increase in size and number of melanomacrophage centers, bile duct hyperplasia, hyperemia and hemorrhage, fatty changes in the hepatocytes, fibrocyte aggregation and focal inflammatory cells were also the histological lesions observed in the liver of exposed fish. These results showed that oxadiargyl is highly toxic to common carp and had negative effects on the growth performance, serum biochemical parameters and the liver tissue of common carp.

    Keramati, Vida; Jamili, Sh.; Ramin, M. (2010)
    Diazinon on as an organophosphate toxin applied widely in agricultural gardens of Iran, so every year huge volume of diazinon on enter to aquatic ecosystems. In this study, antioxidant enzyme activity (Catalase) were assessed in liver of Rutilus rutilus weighing about 7.0+1.0 g following exposure of fish to 20, 40 and 60 lig L-1 concentration of diazinon at 22.0+1.0°C and acceptable water quality conditions. At the first, LC„ 96 h was determined 4.5 ppm. We have 3 treatments with 3 replicate and 1 controls (without diazinon). on). In each aquarium (Volume: 8 L) were 10 fishes. The result of measuring catalase activity in liver with special kit did not show significant differences between treatment groups and control (p>0.05). Also, regression curve did not show significant correlation between increasing toxin concentration and catalase activity changes. The results showed that in same concentration, catalase activity in time 24 h significantly was higher than times 48 and 96 h (p<0.05). Finally, the results did not show special relationship between different concentrations of diazinon on and catalase activity in fish liver, that is maybe was result of parameters such as antioxidant enzymes conjugative operation, enzymes professional reaction against special pollutant, rapid reactions and acute phase reaction and antioxidant adaptation again. st pollution and antioxidative reaction outbreak in target organ.

  • Morphology and phylogeny of the sea anemone Stichodactyla haddoni (Cnidaria: Anthozoa: Actiniaria) from Chabahar Bay, Iran

    Attaran-Farimin, Gilan; Javid, Pegah; Shakouri, Arash (2015)
    Carpet anemones of the genus Stichodactyla are characterized by having no calcium carbonate skeleton, being flattened with rather short tentacles, being exclusively tropical, and being hosts for clown fish species. Most of the species belonging to this genus, however, are often very similar morphologically; thus, identification by external features is rather difficult. In this study, we have described the morphology and phylogenetic affinities of a carpet anemone species collected from Chabahar Bay. Although the Iranian species showed different coloration patterns within the same geographical area, they strongly resemble Stichodactyla haddoni Saville- Kent, 1893 in having short tentacles densely covering the undulated oral disc and white, pointed, recognizable exocoelic tentacles. Comparison of 18S rDNA with other actiniarians revealed that the 2 Iranian species are closely related to Stichodactyla haddoni, Stichodactyla gigantea, and Heteractis magnifica. This is the first record of Stichodactyla haddoni from the southeastern coast of Iran and the northern part of the Sea of Oman.

  • Antimicrobial Activity of Sea Cucumber (Stichopus variegatus) Body Wall Extract in Chabahar Bay, Oman Sea

    Shakouri, Arash; Shoushizadeh, Mohammad Reza; Nematpour, Fatemeh (2017)
    Seas and oceans have been recognized as a rich source of metabolites and bioactive compounds with biodiversity and drug activity. These compounds have accumulated in various organisms. Bioactive compounds can be extracted from various animal groups, such as coral, crabs, moss animals, Echinodermata, case-bearers, fishes, and sponges. Objectives: Antimicrobial extracts of the sea cucumber body wall (Stichopus variegatus), collected from Chabahar Bay, were tested for four bacterial, fungal, and yeast species. Methods: The disk diffusion method was used in this study. The McFarland 0.5 standard was used in the preparation of suspensions of the mentioned microorganisms under a hood. Next, the species were cultured with a swab on a Mueller-Hinton agar for bacteria and on a Sabouraud dextrose agar for fungi. Subsequently, the disks, with appropriate concentrations, were placed on microbiological growth media. Results: The results of the study showed that the best effect belonged to the aqueous methanol extract of the sea cucumber body wall, with an 8 mg/mL concentration on E. coli, with an inhibition zone diameter of 12.26 mm. The lowest inhibition zone diameter belonged to the methanol extract of white strands, with a 2 mg/mL concentration on C. albicans and an inhibition zone diameter of 1.16 mm. The n-hexane and chloroform extracts had no effect. Conclusions: Comparison of these tests indicates that sea cucumbers have an innate immunity system, which can be considered a potential source for discovering antimicrobial peptides.
