Genetic parameters estimation and optimization of genomic selection in mud crab (Scylla paramamosain): a case study for growth-related traits.

ABSTRACT:

Background

Genomic selection (GS) has become a preferred method for genetic improvement in aquaculture species. However, its application in mud crab (Scylla paramamosain) remains limited. Given that the prediction accuracy of GS varies across species and is influenced by several factors, including statistical models, marker density, and the size of the reference population, a systematic investigation of GS in mud crab is necessary. To explore the impact of these factors on GS and optimize the application strategies of GS in mud crab breeding, a total of 508 mud crabs were genotyped by the 40 K liquid SNP array (named "Xiexin No. 1") to estimate genetic parameters of growth traits and systematically investigate the impact of prediction models, SNP density, and reference population s
