landed here, and no marked ones. There has been a fair 

 percentage of soles, but hardly any plaice to compare with 

 former years." 



I think, then, the cause of the apparent failure of 

 these experiments is that a dispersal of the plaice present 

 in Tremadoc Bay in June and July has taken place.

It will be seen that the plaice recovered from this 

 experiment were all caught quite near to the place where 

 liberated and within the territorial waters. One was 

 recaught by the Aberystwyth first class trawler AB71, and 

 the others by the Southport second class trawler LL343.
