Cod development

Cod development (CODE)
Start date: 1. July 2010
End date: 31. December 2014
Financed by: Research Council of Norway
In cooperation with: UiB, HI, NOFIMA, SINTEF, NTNU, UiTø, BUC
The project is lead by: University of Bergen

Background

CODE is a knowledge platform, funded by the Research Council of Norway, for studies of the development of biological processes in early stages of Atlantic cod, linked to nutritional, environmental and management aspects. A reference material (-The gold standard-), e.g. larvae fed natural zooplankton, will be used as a baseline to describe the ontogeny of a range of mechanisms and biological processes. The larval development will be compared to larvae fed rotifers and the effect of temperature on ontogeny of selected processes will be determined. We will also study how differential nutritional and temperature programming during early stages affect development and performance later in life. The knowledge acquired in CODE is relevant for health management in aquaculture, and for
understanding effects of climate change on stock recruitment of Atlantic cod.

Objective

Primary objective:

  • Gain a deeper understanding of developmental processes in cod and effects of environmental factors (nutrition, temperature).
  •  Identify mechanisms underlying differences in larval quality and recommend improved rearing protocols.

Specific objectives:

  • Describe development of brain, light sensory organs, hypothalamus-pituitary-interenal and -thyroid axes, skeleton, osmoregulation, appetite and digestion, absorption and metabolism of protein and lipid and red-ox balance.
  • Study effects of temperature and first feeding diet on a selection of these processes.
  • Study effects of early programming of fish on their development and performance later in life.
