eDNA Survey for the Endangered Maugean Skate in Bathurst Harbour, Tasmania

Environmental DNA (eDNA) water samples were collected from Bathurst Harbour in November 2021 and February 2022 to detect the presence of the endangered Maugean skate. The dataset likely contains results from qPCR amplification and sequencing of samples, including control samples from Macquarie Harbour. It was published via the Australian Ocean Data Network.

Use Cases

• Assess species presence/absence based on eDNA detection methods described.
• Compare detection rates between two isolated estuaries (Bathurst and Macquarie Harbours).
• Analyze temporal variation in eDNA signals from samples collected in November 2021 and February 2022.
• Validate mitochondrial primer pairs for species-specific detection mentioned in the methodology.

Strengths

• Focuses on a species with one of the most limited distributions of any known extant elasmobranch.
• Uses a modern detection method (eDNA sampling and qPCR amplification) as described.
• Includes control samples from Macquarie Harbour for methodological comparison.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
