The results of this experiment were discussed in last 

 year's Report, but several recaptures have been made 

 during the present year and some doubtful cases have 

 been traced. It may be useful, therefore, to summarise 

 the results anew. Eighteen of the 35 plaice liberated, or 

 over 51 per cent., have been returned, and it will be seen 

 that the positions of recapture are distributed over a 

 considerable area, one fish being taken in the Firth of 

 Clyde, and one off the East Coast of Ireland. It will be 

 noticed that a group of eight fishes have been recaught in 

 inshore waters during the four months after the date of 

 liberation. Two of these had migrated to the South, but 

 were recaptured still in shallow water inshore, while six 

 fishes were taken in almost the same place where those 

 liberated were originally caught. Then we have a group 

 of seven fishes recaptured much further offshore and in 

 relatively deep water, and all from seven to ten months 

 after the date of liberation. Finally, three fishes are 

 included in this year's recaptures : one taken near 

 Dundalk, one in the Firth of Clyde, and one taken 

 probably by a steam trawler not far from Morecambe
