DOES TURBULENCE PLAY A ROLE IN THE FEEDING AND REPRODUCTION OF CALANUS FINMARCHICUS ?
 
Laboratory experiments have shown turbulence to have an important effect on feeding and reproduction of copepods. However, data about the influence in the field are very scarce or nonexistent. In this work, using multiple correlation methods, we considered the possible influence of the turbulence (estimated from the wind speed) on the gut fluorescence and egg production of Calanus finmarchicus using data collected in the North Atlantic and in the Norwegian sea. Wind speed appears to have a significant negative influence on the gut fluorescence but not on the egg production rate. The results are discussed in the context of the actual knowledge about the effect of small scale turbulence on copepod behaviour.
