پرتو هایuv و گاما به واسطه اثرات مخربی که بر dna موجودات زنده دارند، به عنوان عوامل محیطی استرسزا موجب بسیاری از تغییرات فیزیولوژیک از جمله تاثیر بر اسپرم، کاهش لقاح و بدشکلی جنین ماهیان میشوند. هدف از این مطالعه، ارزیابی تاثیر دوز و مدت زمان پرتوهای ماورا بنفش و گاما بر آسیبهای dnaماهی قزل آلای رنگین کمان (oncorhynchus mykiss) بود. در این خصوص تاثیر دوزهای متفاوت پرتوهای ماورابنفش نوع b و c (ب...

The ultra-fast quantitative real-time polymerase chain reaction (qPCR) assay was developed and validated to differentiate the morphologically similar ones, Oncorhynchus keta mykiss. Species-specific primers were designed for COI genes of mtDNA. species-specific O. mykiss selectively amplified by DNA, respectively. sensitivity 1 ng/μL. Quantitative testing showed that results met ‘Guidelines on ...

Ten primer pairs were screened to develop single nucleotide polymorphism (SNP) TaqMan assays that will distinguish California golden trout and some rainbow trouts (Oncorhynchus mykiss sspp., O. m. aguabonita) from the Paiute and Lahontan cutthroat trouts (Oncorhynchus clarkii seleniris, O. c. henshawi). From these 10 primer pairs, one mitochondrial and five nuclear fixed SNP differences were di...

Oncorhynchusmykiss exhibits a vast array of life histories, which increases its likelihood of persistence by spreading risk of extirpation among different pathways. TheKlamathRiver basin (California–Oregon) provides a particularly interesting backdrop for the study of life history diversity inO. mykiss, in part because the river is slated for a historic and potentially influential dam removal a...

Adult steelhead Oncorhynchus mykiss tagged with archival transmitters primarily migrated through a large river corridor at depths >2 m interspersed with frequent but short (<5 min) periods closer to the surface. The recorded swimming depths and behaviours probably provided adequate hydrostatic compensation for the supersaturated dissolved gas conditions encountered and probably limited developm...

The species Oncorhynchus mykiss is characterized by a complex life history that presents a significant challenge for population monitoring and conservation management. Many factors contribute to genetic variation in O. mykiss populations, including sympatry among migratory phenotypes, habitat heterogeneity, hatchery introgression, and immigration (stray) rates. The relative influences of these ...
