Experimental of 1905 was made while trawling in 

 Luce Bay for mature plaice for Piel Hatchery. Twenty 

 fishes were liberated, and during the next twelve months 

 eight of these were returned. Four of these were 

 recaptured in Luce Bay itself, not far from the place of 

 original capture. An interesting result from this experi- 

 ment is that for the first time we have observed a 

 migration from Luce Bay into the Irish Sea. Previously 

 the fishes marked in Luce Bay were recaught in their 

 original habitat, in the Firth of Clyde, or in the Solway, 

 but three (Nos. L865, L8T0, L8T6) of the lot here 

 considered were recaught in the Northern part of the 

 Irish Sea and one (L871) on the East Coast of Ireland, 

 which it probably reached after traversing the waters 

 East of the Isle of Man.
