in this study, seasonal variations of fatty acid amounts in muscle tissues of capoeta caelestis were investigated. we have found that the ω3 contents of c. caelestis in spring, summer, autumn and winter were 17.43%, 15.29%, 17.54%, 13.63% in female and 16.96%, 19.25%, 18.66%, 14.76% in male, respectively. the amounts of ω3 polyunsaturated fatty acids were higher than those of ω6 polyunsaturated...

growth and reproductive attributes were determined for capoeta damascina, an endemic fish species from west of iran. a total of 147 specimens of both sexes were sampled monthly from november 2008 to october 2009. the overall sex ratio was female biased. males were aged 0-4 years and females 0-5 years. the von bertalanffy growth parameters were estimated as; linf=34.81 cm, k=0.27 year-1, t0=-0.6...

in this paper, the metazoan parasite community system of capoeta damascina in the tigris basin (mesopotamian region) in the middle-east is presented. overall, 54 species have been identified. between 2005 and 2008, iranian surveys of capoeta damascina found a total of 47 metazoan parasites species, most identified to species level. in addition, 6 parasite species from iraq and 1 species from oc...

siah mahi, capoeta capoeta gracilis, is a predominant fish in the river systems of the south caspian sea basin. although there is evidence of the geographical divergence of this taxon, but no information is available on genetic differences within the subspecies populations. this study was designed to evaluate variation and differentiation in the tajan river and investigation shahid rajaii dam e...

In this study, changes in malondialdehyde level (MDA), superoxide dismutase (SOD) and catalase (CAT) activity fish liver tissue were investigated by applying two doses of 2,4-dichlorophenoxyacetic acid (2,4-D) herbicide to Capoeta umbla for 72 hours. Changes MDA level, CAT SOD determined spectrophotometric methods. As a result the it was that there statistically significant increase C. exposed ...
