The survey was carried out in the period 13 June to 5 July by 4
vessels, CORELLA (England), EXPLORER (Scotland), JOHAN HJORT
(Norway) and TRIDENS (The Netherlands).
The gear used, the design of the experiment and the method of
fishing were all as described for the 1976 survey by Daan et al
(1976). In addition, a survey was made to the west of Scotland
by the R.V. CLUPEA in a preliminary attempt to delineate the
western distribution of 0-group gadoids because the results of
previous international North Sea surveys had shown that the
distribution of 0-group gadoids does not stop at 5 W, the
present western limit of the international survey. In particular,
the distribution of 0-group haddock in 1978 suggested that these
might be moving from west of Scotland into the North Sea.
(Benjaminsen et al, 1978). The survey by the CLUPEA was carried
out in the standard manner from 5-14 June. The results from this
survey and the international survey are presented separately but
are considered together in the general discussion.
All by-catch data for herring, sprat and sandeel are given in
tables VI - XVIII.
