Genomic testing helps improve trout production in Brazil

Producers of rainbow trout (Oncorhynchus mykiss), one of the most valued cold water fish, can now count on a tool to improve and guarantee the quality of parent stock, breeding stock and fry. Embrapa Genetic Resources and Biotechnology (DF) is already offering, through the AquaPLUS platform, the TroutaPLUS, a service that will help in the evaluation of the structure and genetic diversity within and between commercial breeding stocks of this species. The technology was developed with resources from the Research Support Foundation of the Federal District (FAP-DF) and from Embrapa itself. Researcher Alexandre Caetano explains that research on rainbow trout in Brazil, so far, has focused mainly on ecological and historical aspects of the introduction of the species in the country (see table at the end of the article), the economic viability of the productive system, reproductive, health and management aspects. “There was little information about the composition and genetic structure ...
