There are no new assessment results from 2008 for these oreo stocks.

Black oreo

The stock assessment of OEO 4 black oreo was considered unreliable and was not accepted. However,

abundance indices from standardised CPUE analysis suggests that there was a decline in the stock through the 1980s and 1990s. It is not known if recent catch levels or the current TACC are sustainable or if they are at levels that will allow the stock to move towards a size that will support the maximum

sustainable yield.

Smooth oreo

The OEO 4 smooth oreo stock assessment was updated in 2007. Three final runs are reported for the


The model estimates of mid-year mature biomass in 2005

-06 was 57% (51–62) of mature B0 and


suggests that there is not an immediate sustainability issue with this stock. However, there are

considerable uncertainties associated with this assessment described in section 4.3.6 above. The main

uncertainty is that substantial proportions of the abundance in each acoustic survey are attributed to

layer marks which are generally not fished by the commercial fishery. Also, standardised CPUE in the larger east fishery has declined in recent years.
