Genetic erosion driven by inbreeding and introgressive hybridization in the endemic Manyara tilapia (Oreochromis amphimelas) from Tanzania's saline Rift Valley lakes

Puntos clave

• Genetic erosion is observed in Manyara tilapia populations due to inbreeding and introgressive hybridization, affecting diversity.
• Population genetic assessments reveal significant declines in genetic variation linked to these processes.
• This observational analysis focuses on tilapia populations within Tanzania's saline Rift Valley lakes over recent years.
• These findings highlight urgent conservation measures to protect the unique genetic heritage of Manyara tilapia.
