Article
The taxonomy of oysters along the northern coasts of the Persian Gulf and the Gulf of Oman is not well recognized. We present a phylogenetic analysis of oyster species in these regions. We combined morphological and molecular techniques to obtain the identity of oysters to the lowest taxonomic levels. Analysis of partial nucleotide sequences from m...
Article
The situation of Ramsar sites along the Caspian Sea coast has deteriorated over the past decades, and this is more noticeable in the narrow coastal strip of the south Caspian Sea. In this study we investigate how the Caspian Sea level changes affect the coastal Ramsar sites. Particularly, we focus on the Gorgan Bay in the southeast corner of the Ca...
Article
Mudskippers (Gobiidae: Oxudercinae), are air-breathing fish, that play important roles in the structuring of benthic communities in mangrove habitats, serving as important ecosystem engineers. We used stable isotopes and the Bayesian mixing model to determine if mangrove provides a base of nutritional support to the mudskipper, Periophthalmus walto...
Article
Investigation of aquatic animals' locomotion is of great importance due to their high propulsion efficiency. An efficient algorithm considering all effective parameters is needed to understand the hydrodynamic behavior and their propulsive efficiency. In this paper, a robust three-dimensional unsteady panel method in form of a computer software Pan...
Article
Aim. Analysis of new data on populations of invasive ctenopfores Вeroe ovata and Mnemiopsis leidyi in the Caspian Sea and assessment of adaptation of B. ovata to new habitat conditions.Material and methods. The data was obtained in the Dagestan sector of the Middle Caspian Sea in September‐November 2021. Ctenophores and zooplankton were collected b...
Article
The aim of this study was to examine the combined effects of thyme essential oil (TEO) and prebiotic (Immunogen ®) on growth performance, hematological parameters, innate immunity, and oxidative status of rainbow trout, Oncorhynchus mykiss. For this purpose, the fish (11.92±0.06 g) were fed (3% of biomass) experimental diets that contained 0 (Contr...
Article
Oysters are widespread throughout the intertidal regions, and accurate identification and monitoring of their ecological status are still difficult due to their high level of plasticity. Anthropogenic activities facilitate oyster dispersal to new habitats through the shipping and elimination of existing barriers. In this study, a combination of mor...
Article
In this article dissolved oxygen results of research cruises through the Persian Gulf during 2018–2019 are discussed. The results showed that summer to autumn hypoxia occurred mainly at depths ≥ 50 m to the bottom. This seasonal hypoxia started in late summer reaching its greatest severity in mid-autumn with an area of 50,000 km² in the Persian Gul...
Article
Despite the economic and political importance of the Persian Gulf and the vast amount of marine trade carried on, mainly in tanker traffic, chemical oceanographic properties of the area, particularly nutrients and chlorophyll a had been measured only a few times in the past (expeditions of the Research Vessels Meteor (1965), Atlantis II (1977), Umi...
Article
Common carp were fasted for 0, 3 and 14 days prior to exposure to a 2‐hr crowding stress. Serum cortisol, glucose, lactate, T4, T3, serum alternative complement (ACH50), lysozyme, total immunoglobulin (Ig) and blood WBC were determined before and 0, 6 and 24 hr after the crowding stress. Three days of fasting led to a significant decrease in serum...

The purpose of this study was to evaluate the distribution of the medicinal leech, Hirudo medicinalis, in the containers, type of motion in the water recirculating system, and to find the optimal frequency of exchange of water in this system. According to the results, there are found that the living conditions, created in the experimental group wit...

Given the importance of the Persian Gulf, the Strait of Hormuz and the Gulf of Oman in terms of biotic and abiotic resources and various strategic issues and considering the increasing stress on these valuable marine environments, the development of a long-term monitoring program in its all related fields seems to be essential. The Iranian National Institute for Oceanography and Atmospheric Science, in line with its missions has formulated a long-term monitoring program (applying advanced measurement and sampling equipment , specialized staffs in various oceanographic sciences, it’s well-equipped laboratories and research vessel (Persian Gulf Explorer) to study and monitor the biotic and abiotic factors in the Persian Gulf, the Strait of Hormuz and the Gulf of Oman in the field of oceanography. Regular studies in various fields including physical, chemical and biological oceanography, marine geology, satellite oceanography and atmospheric science are programmed in a specified monitoring network with a defined timetable.
