The distribution of young cod. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
Abstract
The distribution of young cod in the North Sea is described,
using catch data from national and international trawl surveys
and experimental fishing. Information on seasonal movements
and feeding related to the concentration in the winter of I- and
II-group cod in shallow, low salinity water is presented.
The pelagic 0-group cod in June move rapidly inshore by
September-October and remain there as I-group fish until the
spring. In the summer the majority move offshore returning
again for the winter as II-group. Cod older than II-group
generally avoid shallow, low salinity water. An analysis of
food types of the age groups indicates that this behaviour
reduces cannibalism.
