MetadataShow full item record
In 1985 investigations were started to try to measure the abundance of 0-group saithe before the main concentrations entered the inshore waters. In 1986-1988 the investigation area was. expanded to also cover the eastern part of the northern North Sea. This report gives some results from the cruise in April-May 1988, In 1987 the results indicated that the end of April was too late to get a good measurement of the 0-group from the North Sea, Tbe cruise indicate, however, that this is too early to start. For the northern stock (north of 62°N) the chosen time seems to be all right.
