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 study, forty healthy fish were selected and divided in to two groups as control and treatment. The treatment group was treated with 1/2000 concentration of organic germicide for 45 min (according to the manufacturing protocols). At 4, 8, 12, 24, 48 and 96 h after bath challenge, 5 specimens were collected from treatment and one from control group. Gill, brain, kidney, and liver of all fish were sampled. Some histological damages such as edema and detachment of basic layer in secondary gill filaments were observed in gill microscopy results. The most important histological changes observed in the brain were congestion of some blood vessels. Furthermore, some evidences of increased melano-macrophage, glomerular shrinkage, and dilatation in Bowman capsules were recorded whereas no any damages were observed in liver. All histological changes removed after 48-96 h. It could be concluded that, all pathological observations in this study were just a natural response of fish body after exposing to the new disinfectant, and they were not recorded any damages like those which happen against hazardous chemicals. It seems that there is no risk associated with the consumption of this disinfectant for the fish tissues.}, Keywords = {Rainbow trout, Organic germicide, Kidney, Liver, Gill, Brain, Histopathology}, volume = {12}, Number = {3}, pages = {500-510}, publisher = {Iranian Fisheries Research Organization}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, url = {http://jifro.ir/article-1-1088-en.html}, eprint = {}, journal = {Iranian Journal of Fisheries Sciences}, issn = {1562-2916}, eissn = {}, year = {2013} } @article{ author = {Afzali, M. and RahimiMianji, G. and Gholizadeh, M.}, title = {Genetic variability of rainbow trout (Oncorhynchus mykiss) cultured in Iran using molecular RAPD markers}, abstract ={In the present study we evaluated the amount and distribution of genetic variation by using RAPD marker variation of 12 markers loci in three broodstock groups of rainbow trout.

It was sampled from three stations placed in different tributaries in Karoon drainage and evaluated to understand the molecular phylogenetic relationships of Turcinoemacheilus in Iran. The mitochondrial cytochrome b gene (cyt b) and control region were used to infer phylogenetic relationships. PCR amplification of control region was not carried out successfully, possibly due to the high divergence of this sequence in the studied genus. The amplified fragments of cyt b were sequenced then analyzed by the use of phylogenetic software. Only one divergent position was seen in all three samples stations located in amino acid position 365. GTR and p-distances of cytochrome b gene for T. kosswigi computed from different stations of running water in Karoon drainage showed these samples belong to different populations and fall in intraspecific differences.

The purpose of this study was to elucidate the factors affecting antimicrobial effectiveness of essential oils Rosmarinus officinalis, Zataria multiflora, Anethum graveolens and Eucalyptus globulus against food spoilage and pathogenic bacteria, Streptococcus iniae the cause of zoonotic streptococcosis in fish. Food conservation is based on an intermittent search for foods with a high nutritional quality and microbial stability and it has been reached by the control of the growth / survival of spoiling and pathogen foodborne microorganisms. Based on several reports, fish streptococcosis is currently considered as one of the main limiting factors in the aquaculture industry, due to the significant economic losses (annually more than $150 million) that these infections cause in different cultured fresh and seawater fish species worldwide. The sensitivity of S. iniae to antibacterial activity of the essential oils was determined using well diffusion assays and paper disc diffusion method. The ranges of minimum inhibitory concentration (MIC) of the oils and extracts were 3.9–250 and 7.8- 500 µg/ml and the ranges of minimum bactericidal concentration (MBC) values for the oils and extracts were found to be in the range of 7.8-250 and 15.6-500 µg/ml, respectively. The essential oils exhibited antibacterial activity against S. iniae. The essential oil of rosemary showed the strongest antimicrobial activity.}, Keywords = {Essential oils (EO), Rosmarinus officinalis, Zataria multiflora, Anethum graveolens, Eucalyptus globulus, Antibacterial activity, Minimum inhibitory concentration (MIC) }, volume = {12}, Number = {3}, pages = {702-716}, publisher = {Iranian Fisheries Research Organization}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, url = {http://jifro.ir/article-1-1104-en.html}, eprint = {}, journal = {Iranian Journal of Fisheries Sciences}, issn = {1562-2916}, eissn = {}, year = {2013} } @article{ author = {Bilen, S. and MügeBilen, A.}, title = {Effects of different protein sources on growth performance and food consumption of goldfish, Carassius auratus}, abstract ={}, Keywords = {}, volume = {12}, Number = {3}, pages = {717-722}, publisher = {Iranian Fisheries Research Organization}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, url = {http://jifro.ir/article-1-1105-en.html}, eprint = {}, journal = {Iranian Journal of Fisheries Sciences}, issn = {1562-2916}, eissn = {}, year = {2013} } @article{ author = {Kocabaş, M. and Başçinar, N.}, title = {The effect of salinity on spotting features of Salmo trutta abanticus, S. trutta fario and S. trutta labrax of cultured brown trout}, abstract ={}, Keywords = {Spotting, Salinity, Brown trout, Salmo trutta abanticus, Salmo trutta fario, Salmo trutta labrax.}, volume = {12}, Number = {3}, pages = {723-732}, publisher = {Iranian Fisheries Research Organization}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, url = {http://jifro.ir/article-1-1106-en.html}, eprint = {}, journal = {Iranian Journal of Fisheries Sciences}, issn = {1562-2916}, eissn = {}, year = {2013} } @article{ author = {Saeedi, A.A. and Pourgholam, R. and Shohreh, P. and MehdizadehMood, S. and Moghimi, M. and Nasrollahzadeh, H. and Zahedi, A. and Safari, R. and Habibi, F.}, title = {Parasites and bacteria isolated from ctenophore invaders, Mnemiopsis leidyi and Beroe ovata}, abstract ={}, Keywords = {}, volume = {12}, Number = {3}, pages = {733-736}, publisher = {Iranian Fisheries Research Organization}, title_fa = {}, abstract_fa ={}, keywords_fa = {}, url = {http://jifro.ir/article-1-1107-en.html}, eprint = {}, journal = {Iranian Journal of Fisheries Sciences}, issn = {1562-2916}, eissn = {}, year = {2013} }
