Predation Risk Factors for Southern Rock Lobster in South Australian Fisheries

Research from Parks Australia examines in-pot lobster predation by Maori octopus, analyzing factors like lobster size, sex, season, fishing zone, and catch rate. The dataset was last updated on 2026-07-16 and is provided to maintain access following the decommissioning of the Australian Marine Parks Science Atlas platform. It aims to inform fishery management decisions to reduce economic losses.

Use Cases

• Modeling predation risk based on lobster size and sex mentioned in the description
• Assessing seasonal and spatial patterns of octopus predation within discrete fishing grounds
• Evaluating the economic impact of depredation on South Australian rock lobster fisheries
• Informing fishery management strategies based on variable depredation rates

Strengths

• Research examines multiple factors: lobster size, sex, season, fishing zone, and catch rate.
• Dataset is provided by Parks Australia, an authoritative government organization.
• Analysis uses mixed modelling techniques as described.

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 South Australia.
