[ 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...

[ 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 const...

[ 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 ...

[ 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 م...

[ 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 pho...

[ 10 ] - Effect of CuSo4 sub-lethal concentration on some hematological indices of Rainbow Trout Oncorhynchus mykiss

The present study was designed to investigate the effects of 0.0125, 0.035, 0.075 and 0.15 ppm sub-lethal concentration of copper on hematological parameters (Hb, HCT, RBC, WBC, MCV, MCH, MCHC, lymphocyte, monocyte, neutrophil and eosinophil count) of the Oncorhynchus mykiss. Samples weighted 18±3 gr and exposure to CuSo44 for a week. Physicochemical properties of water were 14±2 Cº temperature...

[ 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. Signif...
