background: pesticides are widely used in agriculture. excessive use of pesticides has health risk for human and threatens non-target organisms. this research aimed to determine lethal concentrations of malathion and hinosan for carassius auratus (5±1 gr) [mean ± sd]. methods: experiments were performed according to o.e.c.d for 4 days (96 h) and concentrations of 0, 1, 2, 4, 8 mg l-1 hinosan an...
The effects of dietary supplementation of commercial human probiotic, Lactobacil and antibiotic, oxytetracycline on the growth, survival, disease resistance and content of intestinal microflora in two ornamental fishes, viz., goldfish, Carassius auratus and swordtail, Xiphophorus helleri were studied. The total wet weight gain, food conversion ratio and specific growth rate of C. auratus did no...
polybrominated diphenyl ethers (pbdes) have been widely used in many products as flameretardants, which resulted in their release into the environment. little is known about the impact of coexisting pbdes on organisms. in this study, the in vivo effects of bde-47 and bde-99 on a suite of biomarkers, acetyl cholinesterase (ache), ethoxyresorufin-o-deethylase (erod), glutathione-s-transferase (gs...
Monogenoidea pathogenic activity can elicit various histological responses in fish. Species of Ligophorus are specific parasites of mullets, and its relationship with host fish may result in a moderate pathogenic action. In order to ascertain this relationship, estuarine mullets (Mugil liza) were collected in an estuary, reared in laboratory, for three weeks, and forwarded for histological and ...
Twenty-four polymorphic microsatellite loci were isolated and characterized for Liza affinis using a (GT)13-enriched genomic library. The number of alleles per locus ranged from 3 to 9, with a mean number of 6.250. The observed and expected heterozygosities ranged from 0.417 to 1.000 and from 0.550 to 0.861, with an average of 0.859 and 0.779, respectively. Deviation from Hardy-Weinberg proport...

In order to evaluate the eco-toxicological effects of Roundup on Carassius auratus (C. auratus), fish were exposed to 32 μg/L Roundup, isopropylamine salt of glyphosate (G.I.S) and polyoxyethylene amine (POEA) over different periods (0.5, 1, 3, 7 and 14 d). Hydroxyl radical (·OH), malondialdehyde (MDA) and acetylcholinesterase (AChE) in liver were detected in this study. Results showed that the...
در تحقیق حاضر ماهیان گاریز (مید) (liza klunzingeri) مشکوک به بیماری نکروز عصبی ویروسی (vnn) از این نظر مورد بررسی قرار گرفتند. نمونه ها حاصل از چند مورد وقوع تلفات در منطقه بندرعباس در سال 1389 بودند. محدوده طولی اکثر ماهیان 8 الی 18 سانتیمتر بوده و وزن آنها نیز 15تا 20 گرم بود. ماهیان در حال مرگ دارای علایمی از قبیل رنگ پریدگی و تغییر رنگ پوست بدن، شنای غیرطبیعی، شنای خوابیده بر پشت، عدم جهت ی...
Background and purpose: Cold-smoking is one of the most common ways to increase the shelf life of fish during storage. Materials and methods: This study aimed to extract and measure the polycyclic aromatic hydrocarbon (PAH) carcinogens, using high-pressure liquid chromatography (HPLC)-mass, fatty acids profile, nutritional value, and bacterial community in three widely-used species of smoked f...
