A species-specific qPCR assay targeting the cytochrome b (Cytb) mitochondrial DNA region detected Sousa chinensis environmental DNA in Hong Kong seawater samples, including 28 coastal samples from July 2024.
- Why it matters: Sousa chinensis is declining in Hong Kong waters, but traditional sightings are limited, creating a need for sensitive, field-applicable monitoring using eDNA.
- What they did: The study designed primers and a TaqMan probe for Sousa chinensis Cytb, then tested specificity and evaluated limits of detection and quantification before applying the assay to Hong Kong water samples.
- The result: The assay detected Sousa chinensis eDNA in samples collected near recent sightings and across 28 coastal water samples from western and southern Lantau in July 2024, supporting an eDNA survey framework.
