New record of larval Hysterothylacium sp. (Nematoda: Raphidascar-ididae) in pick handle barracuda (Sphyraena jello) ) from the Persian Gulf, Iran

Pick handle barracuda (Sphyraena jello) ) is one of the most important commercial species in the Persian Gulf. In order to investigate prevalence and intensity of nematoda, 150 S. jello  from three sites (Khuzestan, Bushehr and Hormozgan provinces) of the Iranian coast of the Persian Gulf were monthly investigated in the period 2012-2013. The nematodes belonging to the genus Hysterothylaci...

Antibacterial activity, antibiotic susceptibility and probiotic use of lactic acid bacteria (LAB) in Persian sturgeon (Acipenser persicus)

Growth behavior of five lactic acid bacteria previously isolated from Persian sturgeon (Acipenser persicus), were evaluated at different pH, temperature and salt concentrations. Also, antibacterial activity of extracellular products (ECPs) of this LAB were assessed to Aeromonas hydrophila . Further, their antibiotic susceptibility was determined with some commonly used antibiotics in aquacultur...

The Effects of Lead Toxicity on the Hematological Parameters Common Carp (Cyprinus carpio) at Varying Salinity Levels

Background: Lead (Pb) is an important metal used in industries, mining and agriculture. It is equally important to the aquatic ecosystems and has negative impact on the health of aquatic organisms. Methods: The LC50 of lead toxicity at varying salinities was first determined for 96 hours. Then juvenile fish were transferred to tanks individually and were exposed to 0, 15, 30, 60 and 120 mg/l o...

Fungal Contamination of Feed Material Manufactured in Iran with Emphasis on Its Importance in Safety of Animal Origin Foods

Background: Mycotoxins are a group of structurally diverse substances produced by a wide range of moulds. These fungal secondary metabolites, whose presence in feed is unavoidable, can impose hazards to human and animal health. Continuous concern about potential effects of mycotoxins in the human diet has led to an increasing interest in researches about fungi and mycotoxin production. The aim ...

Isolation, phenotypic and molecular characterization of motile Aeromonas species, the cause of bacterial hemorrhagic septicemia in affected farmed carp in Iran

Background: Motile Aeromonas species cause heavymortalities in carp farms during spring and summer in Iran. Objectives: The aim of this study was to detect phenotypicand genotypic characterization of motile Aeromonas species isolated fromdiseased carps in some northern and southern provinces of Iran. Methods: A number of 40 samples from 22 fish farms werecollected. The identified motile Aeromon...
