[ 1 ] - Effects of Aloe Vera crude extract on growth performance and some hemato-immunological indices of Oncorhynchus mykiss in farm scale
BACKGROUND: The immunostimulating effect of Aloe vera in mammals has been documented, but few works were done on effect of A. vera on fish health and immune responses. OBJECTIVES: In this study the effect of oral administration of A. vera on growth indices, hematological parameters and immune responses of rainbow trout were investigated. METHODS: One thousand five hundred rainbow trout fingerli...
[ 2 ] - Acute toxicity evaluation of five herbicides: paraquat, 2,4-dichlorophenoxy acetic acid (2,4-D), trifluralin, glyphosite and atrazine in Luciobarbus esocinus fingerlings
Background: Evaluation of herbicide pollution in aquatic environments needs the great concern and the most important echo-pollutant effects of herbicides are related to their effects on non target aquatic organisms. Native fish can serve as a proper bio-indicator for evaluation of pollution on aquatic ecosystems. OBJECTIVES: To find environmentally friendly herbicides, in this study the acute ...
[ 6 ] - Effects of Two Probiotics, Lactobacillus Plantarum and Lactobacillus Bulgaricus on Growth Performance and Intestinal Lactic Acid Bacteria of Cyprinus Carpio
Background: The application of probiotics to aquaculture is rather new. Probiotics affect the intestinal microbial flora of fish and subsequently modulate its immune response and growth performance. OBJECTIVES: This study was conducted to evaluate the effect of food supplementation with L.plantarum and L.bulgaricus on growth performance and gut microbiota of Cyprinus carpio. METHODS: For this p...
[ 7 ] - The first report on epicardial cavernous hemangioma in farmed sturgeon, Acipenser baerii, a microscopic survey
Haemangioma is a benign tumor of vascular endothelial cells or their progenitors. In spring of 2016, an Acipenser baerii, (+3 years, 2.2 kg weight) was reffered to the Department of Aquatic Animal Health, Faculty of Veterinary Medicine, Shahid Chamran University of Ahvaz. After dissection it was found that the heart had a cobblestone appearance which was characterized by multiple dark red cysts...
[ 8 ] - Evaluation of silver nanoparticles toxicity in Daphnia magna: Comparison of chemical and green biosynthetic productions
Recently nanoparticles, particularly silver nanoparticles, are broadly used in industry, hence the contamination of the environment with AgNPs has caused considerable concern. In this study, the toxicity of biosynthetic nanosilver produced by two macroalgae: Sargassum boveanum and Ulva flexuosa extracts were compared with chemical nanosilver in Daphnia magna. Size and quality of nanoparticles e...

[ 10 ] - تاثیر مصرف خوراکی عصاره الکلی جلبک Laurencia snyderia وSargassum angustifolium برمیزان رشد، بازماندگی و رنگدانه‌های پوست ماهی ماکرو (Labidochromis caeruleus)
جلبک قهوه‌ای (Sargassum angustifolium) و جلبک قرمز (Laurencia snyderia) از جمله جلبک‌های دریایی مهم خلیج فارس محسوب می‌شوند که منابع مهمی از پروتئین‌ها، ویتامین‌ها، مواد معدنی و رنگدانه‌ها می‌باشند و مهم‌ترین رنگدانه‌های موجود در جلبک‌های دریایی کاروتنوئیدها هستند. به منظور مطالعه‌ی اثربخشی جلبک‌های دریایی بر رشد و رنگ پذیری ماهی زینتی ماکرو، 210 قطعه ماهی با میانگین وزن ...
[ 11 ] - مقایسه سمیت نانو ذرات نقره در سه گونه ماهی کپورمعمولی (cyprinus carpio)،آمور (Ctenopharyngodon idella) و فیتوفاگ (Hypophthamichthys molitrix)
ترکیبات نقره از دیرباز اثرات ضدعفونی کننده داشته و در آبزیان نیز امکان استفاده دارند. در این تحقیق اثرات سمی (50LC) دو محصول کلوئیدی محلول در آب نانوذرات نقره (L2000 و LS2000) در سه گونه ارزیابی گردید. بدینمنظور ماهی ها به مدت 96 سا...
[ 12 ] - ارزیابی مقایسه ایی سمیت نانوذرات نقره شیمیایی و بیوسنتز شده توسط دو گونه ماکروجلبک دریایی در شاخص زیستی آرتمیا
زمینه مطالعه: نظر به گرایش فزاینده به استفاده از نانو مواد مختلف در سطح جهان و راه یابی نهایی آن‌ها به اکوسیستم‌های آبی، سنجش سمیت آن‌ها بر محیط زیست آبزیان و ارائه راهکارهای زیست سازگار در تولید آن‌ها، ضروری به نظر می‌رسد. هدف: در این راستا در تحقیق حاضر، سمیت نانوذرات نقره شیمیایی و بیوسنتز شده توسط جلبک‌های دریایی با استفاده از نشانگر زیستی آلودگی، ناپلیوس آرتمیا (Artemia fransiscana) ارزیاب...
[ 13 ] - Comparative toxicities of five herbicides on nauplii of Artemia franciscana as an ecotoxicity bioindicator
Artemia is one of the most important test organisms available for ecotoxicity test. In this study the toxicity of five widely used herbicides formulations including: Paraquat, 2,4-dichlorophenoxy acetic acid (2,4-D), Trifluralin, Glyphosite and Atrazin were compared using ecotoxicity bioindicator, Artemia franciscana. Acute toxicity (48 h LC50) of five herbicides were determined via OECD standa...
[ 14 ] - Effects of Lipopolysaccharides (LPS) of Yersinia ruckeri on Immune Response in Rainbow Trout (Oncorhynchus mykiss) by Intraperitoneal and Oral Administration
BACKGROUND: Recently, the researches about herbal medicines as substitutes for chemical drugs have risen in number. OBJECTIVES: To add more aspects to this research area, this study evaluated the changes in biochemical factors of the blood serum due to the consumption of Thymus daenensis extract and the effect of the period of its consumption int...
