Discrimination of bile acids by the rainbow trout olfactory system: Evidence as potential pheromone
(Sociedad de Biología de Chile, 2008)
First report of swim bladder-associated microbiota in rainbow trout (Oncorhynchus mykiss)
(Japanese Society of Microbial Ecology, 2017)
The aim of the present study was to identify major bacteria associated with the swim bladder in the rainbow trout, Oncorhynchus mykiss. We extracted DNA from the swim bladder and gut contents in order to perform a temporal ...
Further Evidence of Chromosome Abnormalities in Normal and Haploid Gynogenetic Progenies of Rainbow Trout, Oncorhynchus mykiss
Gynogenetic haploid progenies of rainbow trout, produced using UV light for sperm inactivation, were studied in comparison with normal progenies. In a total of 437 normal embryos, 3.5% of them showed chromosome abnormalities: ...
Local regulation of immune genes in rainbow trout (Oncorhynchus mykiss) naturally infected with Flavobacterium psychrophilum
Flavobacterium psychrophilum is the etiological agent of bacterial cold water disease (BCWD), also referred to as rainbow trout fry syndrome (RTFS), a disease with great economic impact in salmonid aquaculture. Despite ...
Discrimination of bile acids by the rainbow trout olfactory system: evidence as potential pheromone
(Soc Biolgia Chile, 2008-01-01)
Electro-olfactogram recording was used to determine whether the olfactory epithelium of adult rainbow trout is specifically sensitive to bile acids, some of which have been hypothesized to function as pheromones. of 38 ...
Synaptonemal complex formation in spermatocytes of the autotriploid rainbow trout, Oncorhynchus mykiss (Pisces, Salmonidae)
Meiotic cells of triploid male rainbow trouts were analyzed by a surface-spreading SC technique in order to show the process of chromosome synapsis. At zygotene the formation of SCs involved, almost exclusively, two sets ...
SYNAPTONEMAL COMPLEX-ANALYSIS IN SPERMATOCYTES AND OOCYTES OF RAINBOW-TROUT, ONCORHYNCHUS-MYKISS (PISCES, SALMONIDAE) - THE PROCESS OF AUTOSOME AND SEX-CHROMOSOME SYNAPSIS
(Rapid Science Publishers, 1995-05-01)
The surface-spreading synaptonemal complex (SC) technique was employed to analyze spermatocytes and oocytes of rainbow trout in order to visualize the process of autosome and sex chromosome synapsis in this species. The ...
Can the polyculture with South American catfish improve the feeding efficiency of rainbow trout culture?
The objective of this study was to determine if the South American catfish (Rhamdia quelen) is suitable to be farmed in polyculture with rainbow trout (Oncorhynchus mykiss) in intensive systems during the juvenile phase ...
Effects of autoclaving on the apparent digestibility coefficient of dehulled pea seed meal (Pisum sativum L.) in rainbow trout (Oncorhynchus mykiss W.)
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2010)
