This assessment updates the 2006 KAH 1 assessment and investigates potential sources of uncertainty. The data used to estimate the natural mortality rate is reviewed and a higher rate is now considered plausible. Alternative indices of abundance were offered to the model and the magnitude of the recreational catch history is now better informed. The model appears to be insensitive to plausible values of steepness. All model configurations suggest that the KAH 1 is at or above the target level of 52% B0.
