Toxicity of Imidacloprid and Propiconazole to Barnacle Larvae, 2018-2019

Standard ecotoxicology protocols determined the effects of two pesticides on larval development of the acorn barnacle Amphibalanus amphitrite. Experiments were conducted in 2018 and 2019 by the Australian Institute of Marine Science (AIMS) as part of the NESP TWQ 3.1.5 project. The dataset contains results from 4-day larval development bioassays, likely including metrics like survival and transition rates to cyprid stage.

Use Cases

• Modeling dose-response relationships for imidacloprid and propiconazole based on larval development rates.
• Assessing environmental risk to marine crustaceans in the Great Barrier Reef catchment based on experimental toxicity data.
• Comparing pesticide sensitivity between barnacles and other marine taxa using standardized bioassay results.

Strengths

• Experiments followed standard ecotoxicology protocols with defined quality control criteria (>70% survival in control groups).
• Pesticide stock solutions were prepared using analytical grade products with purity >=98%.
• Bioassays included multiple treatment concentrations and control groups with three replicate funnels per treatment.

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 data_gov_au, focusing on species sourced from Darwin Harbour.
