Effects of temperature and body size on the swimming speed of larval and juvenile Atlantic cod (Gadus morhua): Implications for individual-based modelling
The routine swimming speed (S) of three groups of 4, 9 and 32 cm total length (L T) juvenile cod (Gadus morhua) was quantified in the laboratory at 6 - 10 different temperatures (T) between 3.2 and 16.7°C. At temperatures between 5 and 15°C, mean group S increased exponentially with increasing T (...
