the aim of this study was to investigate the effects of administering antioxidants, including vitamin c and chitosan on oxidative stress markers in muscle as edible tissues of cyprinus carpio exposed to cadmium chloride. in this experiment, by exposing to 0.2 mg/l cadmium chloride for 21 days, fish were fed a normal diet, diet containing chitosan (1000 mg/kg diet), vitamin c (1000 mg/kg diet) o...

rapid and accurate identification of microorganisms have a significant impact on strategies and fish health management programs. hence, in this study a duplex pcr assay based on the 16s rrna gene for simultaneous detection of aeromonas hydrophila rticc 1032 and escherichia coli rticc 2325 from pure cultures, and challenged fish tissues was performed and their results were compared with the resu...

Domestication can be defined as the artificial selection in animals to achieve morphological, physiological, and developmental conformity human needs, with aim of improving various limitations species under a feeding environment. The future sustainability aquaculture may rely partly on availability numerous domesticated fish species. However, underlying adaptive mechanisms that result domestica...

Chalcalburnus mossulensis from the cyprinidae family is one of the indigenous fish in Gheshlagh Lake of Kordestan, Iran. Ligula intestinalis is one of the infective parasites among various species of fish and causes gonads atrophy.

The aim of this study was evaluation an organic germicide (Aquagerm) histological affects on Rainbow trout (Oncorhynchus mykiss) vital tissues. This new disinfectant is an aquatic antiseptic and mixed-oxidant disinfectant which is produced for the first time in Iran. This new product mechanism is based on oxidant properties of pro-sulphate which attack crucial structures of pathogens. In this s...

Rainbow trout (Oncorhynchus mykiss), round gobies (Neogobius melanostomas), yellow walleye (Stizostedion vitreum), and yellow perch (Perca flavescens) were given Clostridium botulinum neurotoxin type E (BoNT/E) at four doses (0, 800, 1500, and 4000 mouse lethal doses). BoNT/E was sought in the fish tissues at death or at the conclusion of the experiment (10 days after treatment). Fish were divi...
