This study focused on the accumulation of heavy metals (Couper, Nickle, Cobalt, chromium) in the edible tissues of Crucian. Sampling was done in 3 stations (West, Center, and East) of Anzali wetland in 2012. In this study, 10 samples were collected from each site in the standard weight by gill net fishing method and measuring the concentration of heavy metals was performed using flame atomic ab...
In this study, drought characteristics of Arak, Bandar Anzali, Tabriz, Tehran, Rasht, Zahedan, Shiraz and Kerman stations during the statistical period of 1956 to 2015 were studied by Reconnaissance Drought Index (RDI) and Standardized Precipitation Index. Precipitation and temperature data were needed to calculate RDI. Precipitation data was also required to estimate SPI. In this study, Drinc ...
Over the last few decades, Anzali wetland has been at risk of pollutants, especially from heavy metals. The present research analyzes some physical and chemical properties and heavy metals concentration in 27 points in nine stations of Anzali wetland. The samples of each station have been mixed, acidic digested, and analyzed by inductively coupled plasma mass spectrometry (ICP-MS). The mean con...
─ Acute urinary tract infections consist of upper urinary tract infections, including pyelonephritis, prostatitis, intra-kidney abscesses, and around-kidney abscesses, and lower urinary tract infections, including urethra infection and bladder infection. These infections can independently or in combination result in irritation in various parts. They may appear as asymptomatic or as one of the c...
This study was done on wild common carp and main aims were determination of relationships between fecundity and the fish weight, length and age. One hundred individuals of pre-spawning females with a body weight 285.1-5483 g, total length 27.9-67.1 cm and age 4-12 years old, were sampled in Anzali wetland in 2016 and 2017. A mix subsample was sampled of eggs from front, middle and back parts of...
Length weight relationships of Vimba vimba persa were studied. For this purpose 174 fish samples were collected by gill nets, beach seine and purse seine from March through June 2008 at two Guilan fisheries catch stations of Guilan located in Anzali- Kiyashahr regions. Samples were immediately transferred to the laboratory of fish biology at University of Guilan for further an...
Background: Mercury (Hg) is a major environmental contaminant due to its global ubiquity, tendency to bioaccumulate, and toxicity in wildlife. Mercury accumulation in wetlands threatens critical breeding and foraging habitats of many fish and wildlife species. In this study, mercury concentrations were detected in different tissues of pike. Methods: To achieve these purposes, 58 pikes (Esox l...

Following the report of suckermouth catfish (Hypostomus plecostomus) from Anzali Wetland, the present study was conducted to review the biological and ecological characteristics of this species and its effects on aquatic ecosystems. A literature review revealed that the suckermouth catfish is native to South America and one of the most popular species in the ornamental fish industry. This speci...
