Effects on temperature on spontaneous and thyroxine‐stimulated locomotor activity of Atlantic cod
Spontaneous locomotor activity of cod Gadus morhua maintained at 6° C tripled from February to May. In contrast, locomotor activity of cod held at 2° C was significantly lower than at 6° C (between 25 and 65% lower) and the seasonal increase was smaller. Plasma levels of both thyroxine (T 4 ) and tr...
