چکیده هدف از این مطالعه بررسی اثر روش های مختلف آماده سازی اولیه ماهی قزلآلای رنگین کمان (oncorhynchus mykis)(کامل، شکم خالی، فیله و فیله پروانهای) بر کیفیت و مدت ماندگاری طی 4 ماه نگهداری در فریزر خانگی بود. به این منظور ماهیان قزلآلا پس از انتقال به آزمایشگاه و شستشو، به روشهای ذکرشده آماده گردیدند و ارزیابی کیفی ماهیان در انتهای هر ماه از طریق اندازه گیری فاکتورهای شیمیایی (اسیدهای چرب ...
The objective was to analyse the antibacterial ability of members of the intestinal microbiota of Oncorhynchus mykiss specimens on several bacterial target strains that contaminate food and cause disease in humans. Bacterial colonies from an intestinal portion of the 20 specimens of O. mykiss were obtained in different culture media. Several of the colonies showed antibacterial action on differ...

Oncorhynchus mykiss have a diverse array of life history types, and understanding the relationship among types is important for management of the species. Patterns of gene flow between sympatric freshwater resident O. mykiss, commonly known as rainbow trout, and anadromous O. mykiss, commonly known as steelhead, populations are complex and poorly understood. In this study, we attempt to determi...
We report 80,388 ESTs from 23 Atlantic salmon (Salmo salar) cDNA libraries (61,819 ESTs), 6 rainbow trout (Oncorhynchus mykiss) cDNA libraries (14,544 ESTs), 2 chinook salmon (Oncorhynchus tshawytscha) cDNA libraries (1317 ESTs), 2 sockeye salmon (Oncorhynchus nerka) cDNA libraries (1243 ESTs), and 2 lake whitefish (Coregonus clupeaformis) cDNA libraries (1465 ESTs). The majority of these are 3...
approved:__________________________________________________ Carl B. Schreck The extent to which stressful events are maladaptive or adaptive to the long-term survival of fish remains to be better understood. The aim of this study was to identify differentially expressed genes in the livers of rainbow trout, Oncorhynchus mykiss, responding to an experimental stressor. Gene expression responses w...
This work shows that the atypical erythrocytes in triploid rainbow trout Oncorhynchus mykiss were morphologically similar to those of toads. The nuclei of the cells can be bell-shaped, constricted or irregular. It is presumed that such nuclear division is probably amitosis.
