Cod Growth Data
Listed in NASA Earthdata CMR
Data from Cod Growth Workshop, May 8-10 2000, Dartmouth, Nova Scotia, Canada.
Description
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 ("ices.dk/globec/globec.htm"). This webpage contains information on where to get Cod Growth Data for areas of interest to ICES. This information has been taken from the ICES/GLOBEC Cod and Climate Change website "ices.dk/globec"
