    Shakouri, A.; Nabavi, M.B.; Kochanian, P.; Savari, A.; Safahieh, A.; Aminrad, T. (2009)
    Although, sea cucumbers are well known animals in Eastern Asia, in Iran they are not popular marine animals. Divers recorded these animals in their dives but this is the first scientific approach in identification of holoturians in Southeast coast of Iran. All sea cucumbers were collected with SCUBA diving and species identification was done through morphological keys and review of their dermal ossicles. There are two species of sea cucumber belong to genus Holothuria were collected on subtidal zone of Chabahar Bay in the late of 2007. This is the first report of H. hilla, H. parva from Chabahar Bay (North of Oman Sea). This study is revealed the special characteristics of the presented species in order to just identification of them. In the studied areas, H. parva has known as a rare species.
  • Antimicrobial activity of sea Cucumber (Stichopus variegatus) body wall extract in Chabahar Bay, Oman Sea

    Shakouri, Arash; Shoushizadeh, Mohammad Reza; Nematpour, Fatemeh (2017)
    Background: 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.
  • The first report of Micronephthys sphaerocirrata: Nephtyidae in sub-tidal areas of Chabahar Bay

    Shakouri, Arash; Dehani, Esmaeil (2015)
    This study was conducted to identify Micronephthys sphaerocirrata species in sub-tidal areas of Chabahar Bay during the time period from June 2013 to February 2014. The study area is located in south east of Iran Oman - Sistan and Baluchistan coast. The sampling was performed from Shahid Beheshti, Hafte Tir and Konarak ports. The samples were taken seasonally from each port three times from the depths of 2-10 meters by Van-Veen grab (250 cm2) for identification and one liter of sediment was taken to determine the grain size of the sediment habitat M. sphaerocirrata. The samples were sent to the laboratory and the identifications were performed based on the necessary resources and references. Also the environmental factors such as pH, Salinity, temperature in the sample were determined. The results of this study indicated that M. sphaerocirrata species had the highest frequency during autumn.

  • Sea star (Echinodermata) species diversity and distribution in the south-east of Iran (Gulf of Oman)

    Pourvali, Naser; Esfandiar pour, Fatemeh; Shakouri, Arash; Rezai, Hamid (2014)
    Echinoderms are one of the oldest and most important groups of marine organisms which play an important role in the marine ecology especially in the coral reefs. During November 2012 to August 2013, six stations were selected in the intertidal zone at the north of Gulf of Oman according to sea bottom. At each station, the Sea star species of the selected area were counted in 10 m2 with 10 replications. This study was made in three seasons namely autumn, winter and summer. According to the result, cluster analyses showed the site similarity in species abundance and diversity with the same substrata. Maximum and minimum sea star diversity was shown in winter and summer, respectively.
  • Antibacterial and antifungal activity of Holothuria leucospilota isolated from Persian Gulf and Oman Sea

    Adibpour, Neda; Nasr, Farhad; Nematpour, Fatemeh; Shakouri, Arash; Ameri, Abdolghani (2014)
    Background: Emergence of antimicrobial resistance toward a number of conventional antibiotics has triggered the search for antimicrobial agents from a variety of sources including the marine environment. Objectives: The aim of this study was to evaluate the antimicrobial potential of Holothuria leucospilota from Qeshm and Kharg Islands against some selected bacteria and fungi. Materials and Methods: In this investigation, sea cucumbers from two coastal cities of Persian Gulf were collected in March and May 2011 and identified by the scale method according to the food and agriculture organization of the United Nations. Antibacterial activity of hydroalcoholic extracts of the body wall, cuvierian organs and coelomic fluid, methanol, chloroform, and n-hexane extracts of the body wall were evaluated by the spot test. In addition, their antifungal activity was assessed by the broth dilution method. Results: The displayed effect was microbiostatic at concentrations of 1000 and 2000 µg/mL rather than microbicidal. The highest activity of hydroalcoholic extracts was exhibited by body wall, cuvierian organs and coelomic fluid against Escherichia coli, Salmonella typhi, Staphylococcus aureus and Pseudomonas aeruginosa; Aspergillus niger, A. fumigatus, A. flavus and A. brasilensis. However, none of the methanol, chloroform and n-haxane extracts showed appreciable effects against Shigella dysenteriae, Proteus vulgaris, Bacillus cereus, S. epidermidis and Candida albicans. Moreover, cuvierian organs did not possess any antifungal potential.Conclusions: Our data indicated that water-methanol extracts from the body wall of H. leucospilota possess antibacterial and antifungal activity. However, additional and in-depth studies are required to isolate and identify the active component(s).
  • Morphology and phylogeny of the sea anemone Stichodactyla haddoni (Cnidaria: Anthozoa: Actiniaria) from Chabahar Bay, Iran

    Attaran-Fariman, 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 south eastern coast of Iran and the northern part of the Sea of Oman.
  • Feeding habits of the scalloped spiny lobster, Panulirus homarus (Linnaeus, 1758) (Decapoda: Palinuridae) from the South East Coast of Iran

    Mashaii, Nassrin; Rajabipour, Farhad; Shakouri, Arash (2011)
    Certain ecological aspects of the feeding habits of 260 scalloped lobsters Panulirus homarus collected during monthly dives off the southeast coast of Iran were considered. Parameters under consideration included: water temperature, salinity, turbidity, pH, dissolved oxygen and macrobenthose of the lobsters habitat. The mean number of empty stomachs varied from 25% to 62%. Statistical analysis revealed no monthly or seasonal significant difference in the frequency of non-empty stomachs (P>0.05). 1 to 6 prey items were distinguishable in each non-empty stomach. Monthly mean of point counts of prey obtained was from 8.76±4.18 to 154.95±73.62, without any significant difference by Tukeys’ HSD test. Bivalves often had the maximum amounts of Fi and Pi amongst different prey items. Pearson χ2 test did not show any significant difference between frequency of occurrence of each prey item with different length classes, sex, moulting condition and presence of eggs in females (P>0.05). Ivlev electivity index of crabs, gastropods and bivalves was close to 1 and sloped to -1 for polychaetes and echinoderms. This index revealed crabs, bivalves and gastropods were more important in the diet than sediment throughout the year. Frequencies of food occurrence suggest bivalves as the main food; crabs, gastropods, barnacles and algae as secondary food and polychaetes, fish, echinoderms and Ascidiacea as incidental food for P. homarus in the area. Spearmans’ correlation coefficients of stomach fullness against different length classes, sexes, moulting and ovigerous females were not significantly different (P>0.05). There was only a significant Pearsons' correlation between the number of point for bivalves in the stomach against body weight (P<0.05).
