[ 1 ] - Effect of CuO nanoparticles on some hematological indices of rainbow trout oncorhynchus mykiss and their potential toxicity
Objective(s): This study aimed to determine the possible toxicity of Cuo nanoparticles (NPs) on Oncorhynchus mykiss by evaluating hematological parameters.Materials and Methods: Fish were sampled and treated in 4 aquariums containing the concentration ranges of 1, 5, 20 and 100 ppm of CuO NPs. There was one control group (no CuO NPs) and three replicates. The physicochemical properties of water w…
[ 2 ] - Hematological responses of Goldfish (Carassiusauratus) to different acute concentrations of Silver Sulfate as a toxicant
This study aimed to evaluate the efficacy of silver sulfate (AgSO4) as a toxicant in goldfish (Carassiusauratus). One hundred and forty-seven live specimens of C. auratus were obtained and exposed to 1, 10, 100, 500, 1000 and 2000 ppm of AgSO4for 96 hours. There was one control group (no AgSO4) and three replicates. The physicochemical properties of water and the following parameters were constan…
[ 3 ] - Age, growth and spawning season of Luciobarbus esocinus Heckel, 1843 in Gamasiab River, Iran
In current paper reproductive strategy and growth rates of Luciobarbus esocinus were investigated from 2010 to 2012, in Gamasiab River, Kermanshah, Iran. Samples were collected seasonally by gillnet and electro-fisher device. Sex ratio was evaluated from 162 individual and the percentage of male and female individuals were 54.76% and 45.24% respectively. Age structure was distributed between I an…

[ 6 ] - بررسی فراوانی طول کاراپاس، رابطه طول-وزن میگوی سفید سرتیز و تعیین توده زنده (Metapenaeus affinis) در صیدگاه‌های میگو در استان هرمزگان
چکیده این پژوهش، با هدف دست‌یابی به فراوانی طولی، پراکنش، تعیین توده زنده و رابطه طول-وزن میگوی سفید سرتیز در صیدگاه‌های میگوی سفید سرتیز انجام شد. نمونهبرداری به وسیله تور ترال و به روش مساحت جاروب شده از بهمن 1388 لغایت اسفند 1389 صورت پذیرفت. طول بیشینه کاراپاس برای جنس نر و ماده به ترتیب 35 و 47 میلیمتر به دست آمد. بیشترین فراوانی طول کاراپاس برای هر دو جنس مربوط به بازه طولی 20 الی 22 میلیمت…
[ 7 ] - Assessing benthic health of hard substratum macrobenthic community using soft bottom indicators and their relationship with environmental condition
This study aimed to assess ecological quality status of hard substratum macroinvertebrates communities of the Caspian Sea with three ecological indices and their relation with environmental factors. For this purpose benthic communities of the Caspian Sea basin were studied seasonally during 2014 in 8 sampling sites. Temperature, salinity, dissolved oxygen, pH, nitrate, nitrite, silicate and phosp…

[ 10 ] - تأثیر غلظت‌های تحت کشنده‌ی فلز مس (CuSo4) در پارامترهای هماتولوژیک خون قزل آلای رنگین کمان (Oncorhynchus mykiss)
پژوهش حاضر به منظور بررسی تأثیرات غلظت‌های تحت کشنده‌ی 0125/0، 035/0، 075/0 و 15/0 میلی‌گرم بر لیتر فلز مس بر پارامترهای هماتولوژیک خون قزل‌آلای رنگین‌کمان Oncorhynchus mykiss پی ریزی شد. نمونه‌ها با میانگین وزنی حدود 3±18 گرم به مدت یک هفته در معرض سولفات مس قرار گرفتند. دمای آب در طی دوره آزمایش 1±14 درجه سانتی گراد، pH 5/8-7 و سختی کل برابر با 270 گرم بر لیتر کربنات کلسیم بود. شمارش کلی گلبول …
[ 11 ] - Short communication: Morphological analysis of Alburnoides samiii from Toolkhone river, Guilan province, south Caspian Sea basin
This study investigated the effect of the installation of flood dams on the morphological variation of Alburnoides samiii Mousavi-Sabet, Vatandoust & Doadrio, 2015, in Toolkhone River, origin from Somam Mountain, the South Caspian Sea basin, north of Iran. Multivariate analysis (MANOVA) was employed for morphometric characteristics of the fish inhabit upstream and downstream of the dams. Signific…
