Abstract
Total echo abundance of saithe increased by 40 % compared to 2008 but is still among the lowest in the time series since 1992. The indices for all age groups were well below the average. The number of coastal cod increased for all age groups, except for the 2 years old. There are no signs of improved recruitment. It must be emphasized that the stock of coastal cod is for the time being at such a low level that the uncertainty in acoustic abundance estimation is relatively high.
