Physiological measurements from sand flathead (Platycephalus bassensis) collected to examine regional differences in thermal performance between heavily fished southern and lightly fished northern populations in Tasmania. Fish were acclimated for three weeks before measurements of standard metabolic rate, maximum metabolic rate, aerobic scope, and critical thermal maximum at 12.5°C, 15°C, and 20°C. The dataset was published via the Australian Ocean Data Network and last updated on 2026-04-28.
Use Cases
- Modeling population-specific thermal sensitivity based on metabolic rate measurements.
- Assessing the impact of fishing history on physiological resilience to warming based on regional comparisons.
- Analyzing the relationship between acute thermal exposure and critical thermal maximum based on acclimation experiments.
Strengths
- Measurements include three key metabolic metrics (SMR, MMR, AS) and a thermal tolerance metric (CTmax).
- Data collection involved controlled laboratory acclimation for three weeks before testing.
- Thermal responses were measured at three specific temperatures: 12.5°C, 15°C, and 20°C.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the two Tasmanian populations studied.
Provenance
- Source
- Australian Ocean Data Network
- Collection Method
- Fish were captured from two regions in Tasmania and acclimated under common laboratory conditions for three weeks. Measurements were taken using intermittent-flow respirometry.
