The genus Flavivirus, family Flaviviridae, includes a number of important arthropod-transmitted human pathogens such as dengue viruses, West Nile virus, Japanese encephalitis virus and yellow fever virus. In addition, the genus includes flaviviruses without a known vertebrate reservoir, which have been detected only in insects, particularly in mosquitoes, such as cell fusing agent virus, Kamiti...
ازآانجایی که شکل و اندازه سلول‌های قرمز خونی در جنبه‌های فیزیولوژیکی علوم جانوری به خصوص تنفس و انتقال مواد مغذی بسیار مهم هستند، این مطالعه به منظور بررسی تغییرات شکل و اندازه سلول‌های قرمز خونی (ناهنجاری‌ها) در ماهیان قزل‌آلای رنگین‌کمان (Oncorhynchus mykiss)، ماهی آزاد دریای خزر (Salmo trutta caspius) و آمیخته تریپلوئید آن‌ها (Oncorhynchus mykiss ♀× Salmo trutta caspius ♂) انجام شد. القای تر...
Occurrence and distribution of larval and juvenile fish was investigated in nearshore waters of the southeastern Caspian Sea including the Gorgan Bay. Samples were collected during seven surveys using a fine mesh beach-seine in five sampling sites from July 2014 to June 2015. A total of 15500 individuals mostly juvenile were captured, representing 18 species from 8 families. Most juveniles belo...
Nowadays, the use of a wide range of medicinal herbs such as saffron and its aromatic compounds is increasingly being regarded as natural sources of antioxidant properties. In addition to saffron stigma, saffron petal is a rich herbal source of antioxidant compounds. The present study was conducted in a completely randomized design with three replications to study some of the enzymatic and non-...
Although macrobenthic assemblages are considered as major players in many ecosystems around the world, the ecology of Caspian Sea macrobenthos is currently understudied. This study describes the species composition and quantitative distribution of macrobenthos in the southern Caspian Sea and relates the distribution to seasonal changes at three depths (1, 5 and 10 meters) on the Boojagh Marine ...
The effects of dietary protein levels were investigated on growth, carcass biochemical composition and apparent digestibility coefficient in Caspian trout, Salmo trutta caspius. The present study was carried out in a completely randomized design with five experimental diets containing five different dietary levels of protein: 35, 40, 45, 50 and 55%, and 15 fish per replication of each with an i...

Abstract This study was conducted to investigate the possibility of population forming of Oncorhynchus mykiss in competition with Salmo caspius on the southern shores of the Caspian Sea in Mazandaran province, Iran. One hundred fish specimens were collected seasonally from commercial purse seine from October 2017 to April 2018. Brown trout diet was analyzed and a total of 90 individuals belo...
