REPORT ON EXPERIMENTS WITH MARKED 
BISHus DURING THE YEAR 1908. 
By Jas. JOUNSTONE. 
Because of the pressure of other work only two 
experiments were made during 1908. The first was made 
at Piel on 7th April, when 196 plaice, caught in a stake- 
net in Barrow Channel, were put into the tanks at the 
Station and kept there for about a fortnight. They were 
then marked and liberated near to the Barrow Channel 
Bar. The second experiment was made while trawling, 
in Luce Bay, for mature plaice for the Piel and Port Erin 
Hatcheries. 
I have to make the usual acknowledgments of the 
assistance given by the correspondents referred to in 
previous Reports.
