Model Fits

Catch

Fits (blue line) to the catch data (black dots) for all the fleets.

CPUE

Fits to the CPUE data. Each row corresponds with an index. The left-hand panels show the observed (dots) and model predicted (blue line) index in log-scale. The right-hand panels show the log deviations (the observation model is log-normal).

Length Compositions

Model predicted length composition (green line) and observed length composition (grey area) aggregated over all years for each fleet.

Model predicted length composition (green line) and observed length composition (grey area) aggregated over all years for each fleet.

Length composition Pearson residuals showing residuals over time for each fleet. Closed bubbles are positive residuals (observed proportion is higher than expected) and open bubbles are negative residuals. The area of the bubble is proportional to the residual error.

Conditional Age-At-Length

Stock-Recruitment

Time series of spawning biomass and recruitment estimated by the model (upper figures). The lower figures show the stock-recruitment relationship (Beverton-Holt) and the estimated log recruitment deviates.

Selectivity

The estimated selectivity-at-length for all the fleets in the terminal year of the assessment model. The x-axis represents the fish length (cm) and the y-axis is the selectivity value.

Stock Status

Reference Points

The biological reference points.
