Tilapia fish genes 'diverse' (opens original article in a new tab)

A genetic study of blackchin tilapia in Thailand revealed high genetic diversity but couldn't determine how the invasive species spread. The research identified 19 haplotypes and found genetic similarities to West African populations, though exact introduction pathways remain unclear. DNA analysis helps understand population structure but can't identify specific human activities or historical events.

• Genetic study of blackchin tilapia in Thailand found high diversity with 19 haplotypes
• DNA couldn't determine how the species entered or spread in the country
• Samples showed genetic similarities to West African populations but exact pathways remain unclear
