The fish of whose recapture particulars are to hand neither appear to have moved 

 far nor to present marked indications of seasonal migration. With a few exceptions 

 among the largest fishes they stayed throughout the year in water differing very little in 

 depth from that in which they were caught. 



A general trend towards the south or west, irrespective of season, is however observable 

 among the fish recaptured, especially among those which were reported to have been 

 caught at an appreciable distance from the localities of liberation. This may be due to 

 a migration of the small fish towards the English shores: it may also result in part from 

 the topography of the region, grounds resembling the positions of liberation in depth 

 and character being found, in the main, south and west of these points. 



The experiments yield extremely little information as to the movements of fish of 

 60 cm., or more, in length. The behaviour of the few fish of this size retaken has 

 already been mentioned.
