Genetic evaluation of the unknown contribution of stocked fish in angler catches: a case study using mulloway <i> Argyrosomus japonicus</i> Open
Stock enhancement involves the augmentation of wild populations with hatchery-reared recruits. Stock enhancement generally also includes a postrelease monitoring program which tracks stocked individuals within the fishery, and this relies …
View article: Genomic Prediction for Whole Weight, Body Shape, Meat Yield, and Color Traits in the Portuguese Oyster Crassostrea angulata
Genomic Prediction for Whole Weight, Body Shape, Meat Yield, and Color Traits in the Portuguese Oyster Crassostrea angulata Open
Genetic improvement for quality traits, especially color and meat yield, has been limited in aquaculture because the assessment of these traits requires that the animals be slaughtered first. Genotyping technologies do, however, provide an…

Prediction Accuracies of Genomic Selection for Nine Commercially Important Traits in the Portuguese Oyster (Crassostrea angulata) Using DArT-Seq Technology Open
Genomic selection has been widely used in terrestrial animals but has had limited application in aquaculture due to relatively high genotyping costs. Genomic information has an important role in improving the prediction accuracy of breedin…
