Cod Growth Data

Data from Cod Growth Workshop, May 8-10 2000, Dartmouth, Nova Scotia,
Canada. The workshop was proposed by the ICES/GLOBEC Working Group on
Cod and Climate Change. The terms of reference for the workshop were:
- To develop models of growth in order to improve the quality of
stock forecasting;
- To describe major sources of uncertainty in further improving the
prediction of growth rate and advise on further studies to reduce the
uncertainty;
- To assess the contribution of growth rate variability to the
observed variability in stock biomass and stock forecasts; and
- to recommend standard methods for comparing growth rates.

Growth rate varies widely among cod stocks. Large changes in growth
rate have also been observed within many cod stocks. This variation in
growth rate has important consequences for the productivity of these
stocks. Variation in growth rate may reflect effects of temperature
change, density dependence (i.e., changes in per capita prey
availability due to variation in prey or cod abundance), changes in
maturation schedules, changes in size-selective fishing mortality, or
genetic variation. An understanding of the causes of variation in
growth rate among and within cod stocks may lead to improved forecasts
of stock biomass and productivity, and is required to assess the
likely impacts of climate change on cod populations.

To facilitate the exchange of data and ideas, a Discussion/Bulletin
Board for the workshop will be maintained at the ICES/GLOBEC Internet
site ("http://www.ices.dk/globec/globec.htm").
