Seasonal variation in temperature preference of juvenile Atlantic cod ( Gadus morhua), with evidence supporting an energetic basis for their diel vertical migration
Juvenile (3-year-old) Atlantic cod (Gadus morhua) from Broad Cove, Conception Bay, Newfoundland, exhibit seasonal variation in temperature preference. Laboratory studies show that juvenile cod from ambient temperature water prefer temperatures that correlate closely with seasonal changes in the temp...
