This beautiful fish was caught in the Spanish Pyrenees, far outside the fish’s original range. Photo by Sandy Hays World Domination In the spring of 1875, rainbow trout eggs made the journey by train from California to New York—the first time the species had been shipped out of its nati...
3). These results are consistent with shifts in sex and Omy05 karyotype frequencies within the stream among trout across the migratory size range (>100 mm; Fig. 3b,c). The best-fit model of migratory tendency includes sex-dependent dominance of the Omy05 rearrangement, where the ...
Magnetic field perception of the rainbow trout, Oncorhynchus聽mykiss, was demonstrated with a heartbeat conditioning test. The electrocardiogram was measured with subcutaneously inserted silver species of the family Salmonidae. Magnetic field perception of the rainbow trout, Oncorhynchus聽mykiss, was ...
We used the paleolimnological record to reconstruct food web changes in four lakes in interior British Columbia that have been stocked with rainbow trout since the early to mid-1900s. Analysis of pigments, diatoms, and Cladocera was undertaken in cores from all lakes. We predicted that if ...
We recently reported in rainbow trout a regulation of the mRNA abundance of the three receptors of ECs (cnr1, gpr55 and trpv1) under different nutritional status (Díaz-Rúa et al., 2020b). We also demonstrated the presence of a rewarding response in the same species mediated by ECs in...
rainbow trout. Therefore, testing the risk of DNA methylation changes at the spermatozoa level is the first step to be carried on before the consequences on the progeny can be considered. The aim of our study was then to assess whether cryopreservation of rainbow trout spermatozoa can alter ...
Then, during the second phase (Winter: December–March; 103 days), rainbow trout were added in the tanks resulting in a polyculture phase with black bullhead catfish and a second cycle of Swiss chard. During winter, the expected temperature range was below the feeding temperature range of ...
Oil extraction from rainbow trout intestines using UAE Five grams of the wet ground sample was weighed into 40-mL glass vials. Specific amounts of water and NaCl were added to each sample, which were vortex-mixed for 1 min and then placed in an ultrasonic bath (SD-351H, Mujigae, Seoul,...
Ito1*, Jun Kurita1, Koh‑ichiro Mori2 and Niels J. Olesen3 Open Access Abstract In general, viral haemorrhagic septicaemia virus (VHSV) isolates from marine fish species in European waters (geno‑ types GIb, GII and GIII) are non- to low virulent in rainbow trout....
In fish, protein-coding and noncoding genes involved in muscle atrophy are not fully characterized. In this study, we characterized coding and noncoding genes involved in gonadogenesis-associated muscle atrophy, and investigated the potential functional
