1. introduction seas and oceans comprise over 70 percent of the planet earth always taken into attention in the history. however, the most important official and legal actions to regularize a number of claims made by coastal countries regarding the demand of the territorial and marine control and exclusive ownership date the 20th century. the first conference on marine international law was hel...
Using the outline analysis of otolith to study stocks predominant species genus Acanthopagrus (Sparidae family) in Persian Gulf and Oman Sea
Several studies on the white sardine: Sardinella albella, have focused on the identification of stock composition and behavior. In this study population genetic structure and historical demography of S. albella along the cost of the Persian Gulf and Sea of Oman were investigated with a 500-bp segment of mt-DNA control region. In total 40 samples were collected from 3 locations: Jask in Sea of O...
Genetic diversity of sea turtles (hawksbill turtle) was studied using sequencing of mitochondrial DNA (mtDNA, D-loop region). Thirty dead embryos were collected from the Kish and Qeshm Islands in the Persian Gulf. Analysis of sequence variation over 890 bp of the mtDNA control region revealed five haplotypes among 30 individuals. This is the first time that Iranian haplotypes have been recorded...
Small pelagic fishes particularly anchovy (Encrasicholina punctifer) and sardine (Sardinella sindensis) have an important role to support the Iranian fisheries and are distributed along the coastal waters of the Persian Gulf and Oman Sea. Using a logbook on small pelagic fisheries, a GIS-based environmental modeling approach was applied to investigate the presence and abundance of anchovy and s...
Sea water samples were collected from 32 stations in the southern part of the Persian Gulf and the Gulf of Oman during winter of 1987. Surface water of the Persian Gulf exhibited wide range and higher values of salinity (37.15-43.95, mean 40.02%) compared with lower values and narrow range (36.58-36.95, mean 36.74%) in the Gulf of Oman. Surface salinity did not reflect any significant relations...
این مطالعه در سه محل از سواحل بندر لنگه در جنوب ایران، در سواحل شمالی خلیج فارس انجام شد . 119 گونه از جلبکهای جمع آوری و شناسایی شده منطقه که شامل 29 گونه جلبک سبز (2 گونه گزارش جدید)، 31 گونه جلبک قهوه ای (4 گونه گزارش جدید) و 59 گونه قرمز (2 گونه گزارش جدید) می باشد معرفی می گردد.
given the reduced freshwater supplies across the world, seawater desalination is one of the appropriate methods available for producing freshwater. selecting an optimal location is crucial in the installation of these plants owing to the environmental problems they cause. the present study was conducted to identify optimal locations for installing desalination plants in the coastal areas of sou...
sea surface topography (sst) by definition is the separation between the geoid and the mean sea level (msl). the separation between the geoid and msl is caused by various non-gravitational physical effects. if determination of the geoid as the zero point of the height systems from the tide gauge observation be the goal, it is necessary that the affect of the physical effect be precisely compute...
The aim of this study was to assess the ecological factors associated with feeding by Rachycentron canadum (cobia) in the waters of Hormuzgan Province, Iran. Specimens were collected seasonally from Sep. 2014–Sep. 2015 from the Ferdows-1 survey ship and from landing areas in the city of Bandar Abbas. A total of 577 cobia were collected (340 male, 237 female) (20–161 cm Total length). Our result...
