Where have all the codfish gone?
Date:2/26/2014

University of Georgia Genomics Facility in Athens, Georgia.

This publication provides the first publicly accessible, large-scale molecular resource for investigating the physiological ecology of Calanus.

Highlights of this study include:

  • The observation that a large percentage of genes are not in play at any particular time while a young copepod matures;
  • The discovery of specific messages being sent out as individuals prepare to enter a critical dormant phase in their annual population cycle; and
  • The discovery of a number of previously unknown genes, suggesting a more complex biology than that of related animals like the fruit fly and water flea, which are used extensively for biomedical and ecotoxicologial research.

With the Calanus transcriptome in hand, scientist now have a tool to better understand how copepods adapt, and may be better able to predict when and where population changes will occur for this planktonic crustacean on which many fisheries depend.
