Polychaete worms with high species richness and diversity play a key role in the water food chain. In this research polychates of the intertidal zone of Tis coast in Chabahar bay were studied. Sampling was conducted over a period of one year, from summer to winter 2013 and during four seasons by 50 cm×50 cm quadrats. Twenty two families and 30 genera and 4 species were identified polychaetes.Th...
The problem of pollution in the Caspian sea has attracted increasing scientific concerns in recent years, but still, there is limited data relevant to the Gorgan bay. The current study aimed to evaluate the organic pollution of the Gorgan Bay, using Palmer Algal Index. Sampling was conducted seasonally in triplicate from summer 2017 to spring 2018. Phytoplankton samples were collected from surf...
Compounds obtained from marine organisms have been isolated due to their anti-bacterial and antifungal activities. In this study, the antifungal activity of aqueous-methanol, methanol, chloroform and n-hexane extracts of body wall, guts and white strings of sea cucumber (Holothuria leucospilota) collected from Chabahar Bay in 100 to 2000 μg/ml concentrations is discussed. The antifunga...
In this research, the nutritional effects of Sargassum ilicifolium Chabahar Bay, Oman Sea, on cholesterol levels of white-leg shrimp (Litopenaeus vannamei) were studied. The seaweed was collected from coastal areas, rinsed, dried, powdered and the nutritional values were measured in the laboratory. A part of protein resources of shrimp feed replaced with seaweed powder in four treatments (D: as...
The aim of this research was to identify and isolate the fatty acids composition of Nerita textiles in intertidal area of Chabahar Bay, and also to explore the seasonal changes of fatty acid content in Nerita textiles. GC/MS resulted thirteen fatty acids, that saturated fatty acids (SFA) of palmitic acid (16:0) was the most abundant category of fatty acid obtained in total lipids. There were no...
Heavy metals and some organic substances which are drained into the aquatic environments and cannot be decomposed or eliminated will sink into sediments or find their way into different levels of food chain. Bioaccumulation is the process of continuous deposition and aggregation of these substances into the body tissue of living organisms. Mollusks are remarkably appropriate to be used as bio-i...
Introduction: Marine macro algae used in pharmaceutical, medical, food, cosmetics and health. Bioactive compounds in seaweeds have widespread the effects of antibacterial, antitumor, antifungal, antioxidant and anticancer. In this study, the antioxidant properties of the extracts of Cystoseira trinodis collected from the Chabahar Bay were studied. Methods: In this experimental study, methanol,...
The Oman Sea (Makoran) has always been influenced by the monsoon currents, and this phenomenon is a natural stressor for species inhabiting the marine ecosystem, including bivalve molluscs. To study the diversity of subterranean bivalves sampled from three areas of Ramin, Beris, and Pasabandar, a total of 10 stations, in the winter of Pre-Manson, Mansoon and Post Mansoon in 2018. In this study,...
Natural stones (armourstones) of varying sizes and qualities are frequently used to construct breakwaters protect coastal engineering structures from wave actions for economic reasons. Time-related armourstone deterioration in the form abrasion disintegration may result structural damage. Therefore, it is necessary investigate performance quality armourstones, which should be robust long-lastin...
Echinoderms are independent and quite special branch of world animals. Sea cucumbers are among the strangest members of echinoderm class regarding their structure and physiology. These fauna have been tested with regard to anti-bacterial, anti-fungal, anti-coagulants, anti-virus, cytotoxic, hemolytic and anti-HIV features. In this study, the antibacterial activity of Holothuria leucospilota...
