Publication Abstract

Interannual variability in temperature and the recruitment of Irish Sea cod

B. Planque and C.J. Fox

A short review shows that in cold arctic regions of the North Atlantic positive relationships are generally observed between cod recruitment and water temperatures whilst negative relationships are observed in warm-temperate regions. According to this relationship, cod recruitment in the Irish Sea should be negatively related to sea temperatures. Using three independent sources of long-term temperature records we test this hypothesis and show a highly significant connection between the recruitment of cod and winter temperature signals. We suggest that this relationship should be taken into account in any future attempt at understanding or predicting cod recruitment in this area.
