内容記述 |
Rainbow trout is a globally important aquaculture species and has traditionally been cultured in freshwater. Recently, production of rainbow trout in seawater has been increasing due to its potential for faster growth relative to rearing in freshwater. However, a high mortality during adaptation from freshwater to seawater and growth retardation during subsequent rearing period often occur. This study aimed to evaluate the genetic potential for growth and survival of rainbow trout in seawater rearing and to validate the effectiveness of genomic selection (GS) for these traits. Two populations, designated as A and B, were subjected to both freshwater and seawater growth trials. Using GRAS-Di analysis, 11,105 biallelic SNPs were identified in these fish. Survival rate in the seawater rearing was 43.8% for population A and 49.8% for population B, respectively, with the mortality being observed among the sexually matured individuals. Body weight and standard length showed positive correlations between the values in freshwater and seawater (Pearson's r = 0.55). Narrow-sense heritability for growth traits was estimated using the GBLUP method, which revealed moderate values of heritability in seawater (0.57 for standard length, 0.50 for body weight). Genomic estimated breeding values (GEBV) were calculated and a correlation of 0.25 was obtained between GEBV for body weight in freshwater and seawater. Cross-validation demonstrated predictive accuracies of 0.80 and 0.54 for the body weights in freshwater and seawater, respectively. These results indicate a potential for genetic improvements through GS in the growth and survival of rainbow trout in seawater, providing valuable insights for the sustainable aquaculture practices. |
