132 



fishes found were cauo-ht in Red Wharf Bay within the 

 first four weeks. One, however, was taken in the Dee and 

 one in Carnarvon Bay, having? probably p-one through the 

 Menai Straits. 



Station IV .— O ff Great Orme's Head. 



In this experiment the lesults are almost exactly the 

 same as in Experiment III. Two fishes were found in the 

 Dee. Two, however, made very extended migrations, and 

 were found in Newport Bay, in the Milford Fishery 

 District, and off New Quay Head, near the Southern 

 extremity of our own area. 



Station V. New come Knoll. 



This experiment is remarkable because of the 

 extraordinary manner in which the fishes liberated have 

 scattered. Within the first 12 weeks after liberation 

 marked plaice from this station were found in Red Wharf 

 Bay, Menai Straits, the Wallasey shore, the Ribble, and 

 Morecambe Bay. Three also were recaught off the 

 North-East Coast of the Isle of Man. Later on the other 

 fish caught were taken in the waters round Holyhead, and 

 these were probably those which had migrated to that 

 area in the first three months. 



Station VI. -Blackpool Closed Ground. 



This is the most interesting of all the experiments 

 made, and the results are, on the whole, consistent with 

 each other. They are represented on Chart I. by the 

 black circles. If note be made of the length of time 

 elapsing between the liberation and recapture of the fish 

 (this time is indicated by the small figures within the 

 circles), then it is fairly easy to trace the migration paths 

 of the fishes recaught. Out of 78 plaice liberated, 16 were 

 found in the waters of ^Morecambe Bay, and two in the
