Tasmanian Giant Crab Fishery Catch and Biomass Assessment, 2013-2014

Tasmania's giant crab fishery assessment from March 2013 to February 2014, forecasting catch rates and biomass. The report details a total catch of 25.95 tonnes, representing 55.7% of the Total Allowable Commercial Catch (TACC), and a decline in state-wide exploitable biomass to 106 tonnes. The data was produced by Parks Australia and published on data.gov.au.

Use Cases

• Modeling stock biomass trends based on reported catch and effort data.
• Analyzing regional catch rate differences between the West and East coasts of Tasmania.
• Assessing recruitment potential by examining catch rates of undersize crabs.
• Evaluating management effectiveness by comparing actual catch to the Total Allowable Commercial Catch (TACC).

Strengths

• Provides specific catch figures, including 25.95 tonnes for 2013/14 and 26.41 tonnes for 2012/13.
• Includes detailed biomass estimates, such as a decline to 106 tonnes in 2013/14 from approximately 1100 tonnes in the early 1990s.
• Contains regional breakdowns, with West coast catch rates at 27% and East coast at 15% of a 1995/96 baseline.

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 temporal bias inherent to the single-season assessment.
