Original version
This report is not to be cited without prior reference to the authorsAbstract
Catch figures of different demersal species(cod, haddock, saithe etc.)
in the cod-ends of a two level trawl were examined using variable
height of the separating panel (0.5, 0.75, 1.0 and 1.5 m).
Cod enters the trawl mainly in the lower part of trawl while haddock,
and especially saithe, enter the trawl at higher levels. Diurnal and
size dependant effects were recorded.
