Energy losses due to routine and feeding metabolism in young-of-the-year juvenile Atlantic cod ( Gadus morhua )
We examined the effects of body size (313 cm total length) and temperature (4.5, 8.0, 12.0, and 15.5 °C) on routine (R R ) and feeding (R SDA ) energy losses by laboratory-reared, young-of-year juvenile Atlantic cod (Gadus morhua). The magnitude of the effect of temperature on R R , expressed via t...
