The study collected liver tissue samples from Australian Salmon in various states to analyze their genetic variation and population structure. The results showed low levels of genetic diversity in western salmon and only one useful marker system for population structure analysis. The tests revealed no significant differences in genders or age classes, and no significant geographical heterogeneity. The coefficient of kinship was used to measure breeding and was plotted against geographic distance to obtain a visual summary of the salmon's spatial breeding structure. Overall, the study suggests that there is little genetic differentiation between populations of Australian salmon in different regions.
