تحقیق حاضر به منظور بررسی انگلهای خارجی و دستگاه گوارش ماهی گل خورک (boleophthalmus dussumieri) به مدت 6 ماه از دی ماه 1390 تا خرداد ماه 1391 در منطقهی خورآبی ساحل بندرعباس انجام شد. در طول تحقیق، 69 نمونهی ماهی به روش دستی صید و به صورت زنده به آزمایشگاه منتقل گردید. انگلهای جداسازی شده از دستگلاه گوارش در محلول فرمالین 4% تثبیت و به منظور نگهداری به اتانول 70% منتقل شد. در طول دورهی ب...
mitochondria1 dna (mtdna) control region sequences were analyzed to evaluate the population genetic structure of persian sturgeon (acipenser persicus) in caspian sea. a total of 45 specimens were collected from the different locations of the caspian sea. mtdna control region was amplified using pcr. direct sequencing was performed according standard method. the results showed that 12 haplotypes...
in the present study, mitochondrial dna polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) assay was used to assess the population structure and genetic relationships among six persian sturgeon, acipenser persicus populations from south caspian sea along the iranian coast. the complete nucleotide dehydrogenase subunit 5 (nadh 5) region of mtdna amplified by pcr was di...
histopathological and pathomorphological effects of 15 ppb mercuric chloride on persian sturgeon, acipenser persicus, were investigated using histological and electron microscopy observations. light microscopy showed that the gill epithelial hypertrophy, wrinkling and hyperplasia in lamellar epithelia and lamellae fusion occurred after 48 h of exposure. gill epithelia also showed occasional nec...
Twelve species of the genus Ophiomorus DUMÉRIL & BIBRON, 1839 have been identified and introduced so far seven this found in Iran which include four endemic three nonendemic species. Although geometric morphometry is a powerful tool to analyze morphological changes, discovery identification these long relied on traditional morphometric analysis. In study, analyses were used determine morphometr...
Genetic structure of Acipenser persicus, in the Caspian Sea was studied using tetrasomic microsatellite markers. A total of 195 specimens of A. persicus breeders were collected from the sampling stations located in the five fishery catch zones as well as from the Sefidrud River in the south Caspian region. About 2 g of caudal fin samples was collected from each sturgeon specimen and preserved i...
