Great reductions in costs of genotyping using pooled DNA sequencing
Genomic selection is a new powerful method to select the best individuals based on DNA data. It estimates the effects of genome-wide dense genetic markers (SNPs) and uses these estimates to select the parents for the next generation. This selection method is today used in Atlantic salmon breeding programs and its accuracy was tested in FISHBOOST on all the species of the project.
It matters who your mother is, even for fish
In breeding and genetics, the environment provided by the mother, that is the maternal factors like egg size and quality, affect the growth and the size of the offspring produced. A new study has found that including information about the mother (maternal effect) changed the decision about selection of the best breeding candidates in Tilapia.
A view from above and below: Hatchery chinook salmon are self-sorting in tanks
Hatchery-raised chinook salmon sort themselves into surface- and bottom-oriented groups in their rearing tanks. This behavior might be due in part to the fish’s genes, according to an Oregon State University study.
Spanish researchers move closer to Greater amberjack aquaculture with improved hatchery and fattening know how
The research team working on the project “Diversification of Spanish aquaculture through the optimization of the breeding of the greater amberjack (Seriola dumerili) - SERIOLA” is making progress in the development a new commercial species in Spain, by improving the larval stage and optimizing fattening of juveniles.
