| Abstract: | |||||||
|
The ICES International Bottom Trawl Survey (IBTS) quarter 3 (Q3) data, Dutch Beam Trawl Survey (BTS) Q3 data, and ICES stock assessment data were analysed to model the catchability of each 1-cm size class of demersal fish caught in the Q3 IBTS. Estimates of catchability were generally low, suggesting that raw trawl survey density data seriously underestimated actual densities.
